Quick answer: Read the status badge beside your account name in the Twilio Console. Active means the account is not suspended; something narrower stopped, such as one A2P campaign (error 30990) or an unverified toll-free number (error 30032). Suspended with a negative balance: pay. Otherwise Twilio asks you to contact Support within 24 hours, replying to its notification email.
Last updated 26 September 2026. Every Twilio rule here was read on Twilio’s own pages that day.
If you are typing “why is my Twilio account suspended” with an AI calling or SMS campaign stalled halfway through, this page is for tonight. It covers Programmable Voice, Programmable Messaging, A2P 10DLC, toll-free verification and Elastic SIP Trunking, using only what Twilio publishes: its Acceptable Use Policy, Messaging Policy, voice terms, Fraud and Abuse Response Guide and error-code pages. Most of what lifts a suspension is work you can start before anyone replies.
Why is my Twilio account suspended? The four reasons Twilio lists
Twilio’s “Engage: Contact Twilio Support” page defines it: “When an account is suspended, it can’t be used to make or receive calls or SMS messages.” Note receive: inbound is down too, not just the campaign.
The same page groups what it calls “potentially fraud-related reasons” into four categories. All four, as Twilio words them:
- Violation of the Acceptable Use Policy. Sending spam; sending fraudulent, abusive or illegal traffic; phishing, malware or other malicious activity; prohibited content; and “excessive consumer complaints or opt-outs”.
- Directly fraudulent or abusive activity. Specific indicators of fraud or abuse from accounts you own; “unusual spikes in usage that are determined to be fraudulent or could impact Twilio’s platform”; suspected or confirmed account compromise; and use of Twilio to facilitate fraud, chargebacks or abuse.
- Non-payment or zero/negative balance. “If your account balance becomes negative or you have overdue payments, your account will be automatically suspended until payment is made.”
- Security risks. Threats to the platform or other customers, and detected compromise or malicious activity.
Twilio’s error 10001 page adds two causes outside these four: a suspended parent account suspends its subaccounts, and a subaccount’s status can be set to suspended, including by your own code.
For an AI calling team, the first category is the one to read twice: an agent that dials faster than a human team produces complaints and opt-outs faster too. The AUP (last updated 12 May 2025) prohibits breaching rules “that require (a) consent be obtained prior to transmitting, recording, collecting, or monitoring data or communications or (b) compliance with opt-out requests”, and says “if Customer or any End User violates this AUP, Twilio may suspend Customer’s use of the Services.”
A full account suspension is also only one of the interventions Twilio names. Its Fraud and Abuse Response Guide says intervention “can include placing restrictions, deprovisioning phone numbers, suspending your campaigns, or even suspending your affected accounts.” Much first-hour panic comes from reading the first three as the fourth. A Twilio campaign suspension is not a Twilio account suspension, and the status badge tells you which one you have in under a minute.
Is a Twilio suspension as urgent as it feels?
Partly. Two clocks on Twilio’s own pages are real, and neither is measured in minutes.
- The 24-hour contact window. For the four reasons above, Twilio’s Engage page says: “If Twilio suspends your account for any of these reasons, contact Twilio Support within 24 hours to initiate review and reactivation.” That is a request to open the conversation, not a deadline for having everything fixed.
- The 90-day number window. Twilio’s help article on phone number charges during suspension says: “After 90 days of your account being suspended by Twilio, your phone numbers are at risk of being reclaimed.” Your numbers are not lost tonight.
What is not urgent: a billing suspension. Twilio’s reactivation article says the time from payment to reactivation “typically takes 5-10 minutes”, and if the banner persists after 10 minutes, sign out and back in.
What deserves real attention: a suspension for suspected compromise or abuse, because the fix is evidence, which takes days to assemble. Even so, Twilio’s response guide says: “If your account has been restricted, don’t panic.”
Which kind of suspension do I have? The triage table
Start with the badge. Twilio’s help article on checking account status (updated 25 September 2026) says the Console shows one of four states in the top bar beside the account name: Active, Trial, Dormant or Suspended. One detail matters here: for Suspended, “the panel explains the suspension only when the account was suspended because it appears to have been compromised.” For every other cause, the explanation is in your email, not the Console.
Then match what you see to a row; each cause and remedy comes from the Twilio page linked.
| What you see | Account suspended? | Likely cause | What to send Twilio | Evidence to gather |
|---|---|---|---|---|
| Error 10001 “Account is not active” or messages failing with error 30002, and a zero or negative balance | Yes | Billing: balance at or below $0, overdue payment, or failed auto-recharge | Nothing, usually. Pay; reactivation typically takes 5–10 minutes. Contact Support only if it does not come back | Payment receipt; the auto-recharge setting you are about to fix |
| Suspended badge whose panel mentions compromise; unrecognised logins, API keys your team did not create, traffic to countries you do not call | Yes | Account takeover (Twilio calls it ATO) | A reply to the notification confirming containment; an RCA report if asked, and one is required for a repeat takeover | GitHub search result for your Account SID; token-rotation and key-deletion timestamps; Monitor events |
| Suspension notice after a sudden volume spike, often to high-cost country prefixes | Yes | Artificially inflated traffic, usually bots abusing a web form, callback or OTP flow | Proof the entry point is closed: rate limits, CAPTCHA, geo permissions | Targeted prefixes; first-spike timestamp in UTC; cost impact from Usage Summary |
| Suspension notice citing spam, complaints, opt-outs or prohibited content | Yes | Acceptable Use Policy, Messaging Policy or voice-terms breach | Your use case, how consent was collected, and what you have changed | The RCA pack below: consent records, opt-out log, call and message SIDs, scripts |
| SMS failing with error 30990 “Campaign Suspension” | Not by this error alone | One A2P 10DLC campaign (or its Brand) suspended: live traffic not matching the registration, prohibited content, excessive complaints or missing age gating | The remediation the suspension notice asks for; if no guidance arrived, ask Support | Registered use case, description, sample messages and consent flow, side by side with what the agent actually sent |
| Toll-free SMS failing with error 30032 | No: a narrower block | Toll-free number not verified, pending, or rejected | A new or corrected Toll-Free Verification request | The rejection reason; you have a seven-day edit window if the request is eligible |
| Error 22300 when buying a new number | No: a narrower block | Twilio Compliance has restricted provisioning of new long codes | Email to [email protected] with Account SID, business name and a brief use-case explanation | The same three items, written plainly |
| Individual messages failing with error 30007 “Message filtered” | No: a narrower block | Filtering by Twilio or a carrier, not a suspension | Three or more Message SIDs with that error, to Support | The message bodies and the consent behind each recipient |
| Calls connect but show “Scam Likely” on the handset | No: not a Twilio action | Analytics labelling at the called party’s carrier, not Twilio | Nothing to Twilio about a suspension; this is a different remediation path | See the scam-label remediation guide linked below |
The last row is easy to mistake for a suspension: calls going out and being answered less is handset labelling, covered in our guide to fixing AI voice agent calls labelled Scam Likely. An SMS campaign that was never approved is a registration problem, covered in why A2P 10DLC campaigns for AI SMS agents get rejected.
One more trap: API calls failing with error 20003 “Permission Denied”. Twilio lists “the account is suspended or closed” as one of twelve causes; most of the other eleven are credential problems, including a rotated or deleted Auth Token. If your team rotated keys an hour ago, 20003 may be your own doing. Check the badge first.
What to do in the next 24 hours after a Twilio suspension
In order. None of these waits on a reply from Twilio.
- Stop your own queue. Pause the dialler, the agent’s task list and scheduled SMS so they stop retrying into errors. Twilio’s error 30002 page says to “stop any traffic that could violate the Acceptable Use Policy” during a policy review.
- Find the notice. Check every account user’s inbox, including spam. Twilio’s carrier penalties article says carrier warnings go to “the users on your Twilio account who are opted-in to Compliance and Regulatory related alerts”, who may not be the person running the campaign.
- Reply to that email, not a new ticket. The Engage page says “it is critical to reply directly to the Support notification email and follow the instructions provided.” With no notice and no paid support plan, the same page says to ask the Help Center Assistant “I need more help – can I submit a ticket?”. For suspected fraud it gives [email protected].
- Contain if there is any sign of compromise. The guide is blunt: “Do not wait for a response from Twilio Support to start this phase.” The steps in Twilio’s account takeover article include: change passwords for all users, reset the Auth Token (and every subaccount’s), delete existing API keys, enable two-factor authentication for all users, and restrict Voice and Messaging geo permissions to the countries you actually call; it also covers securing your applications and computers, and checking user emails, caller IDs and website security. It also suggests searching GitHub for your Account SID; any result other than zero means the account may be compromised.
- Pay, if it is billing. Then wait 10 minutes, sign out and sign back in before you conclude it has not worked.
- Put inbound somewhere else. A suspended account cannot receive calls, so if your website or ads list a Twilio number, point enquiries at another phone line, such as a staffed mobile, until service returns.
- Do not route around it. Twilio’s 30990 page says: “Do not try to send similar traffic through another existing or new campaign while the suspension is under review. That can lead to additional enforcement on your account.” Its Messaging Policy separately prohibits snowshoeing, and its fraud guide says closing a compromised account and opening a new one “is not recommended unless the root cause has been fully identified and remediated.”
- Start the timeline. Write down, in UTC, when the campaign started, when errors began, when you paused, and every exchange with Twilio. It is item 1 of the pack below.
What to send Twilio to get a suspended account back: the RCA pack
We call this the RCA pack: one folder that gathers the evidence Twilio’s own pages say it may ask for. Its spine is the “Diagnose: Root Cause Analysis” page, which defines a complete RCA as four things: build a timeline, assess the impact, identify the root cause, and define preventative and corrective actions. The consent and calling items come from the Messaging Policy and voice terms, because consent and complaints are the causes an AI outbound operator controls most directly.
For calls, the voice terms set four requirements on telemarketing and advertising calls, and each maps to an item in the pack: obtain the callee’s prior consent as the applicable rules require; clearly disclose the purpose of the call and identify yourself or your organisation at its beginning; provide a way to opt out and honour opt-outs; and do not call numbers on the applicable do-not-call list or registry.
Whether a formal RCA is required depends on the case. For a first account takeover, the Engage page says “in some cases, you may need to provide an RCA report”; a repeat takeover victim “will be required to provide an RCA report.” For a policy suspension, the notice says what it wants. Build the pack either way; at worst it becomes your own post-mortem.
| Item in the pack | What goes in it | The Twilio rule it answers |
|---|---|---|
| 1. Timeline (UTC) | Campaign start, first error, first complaint or spike, pause, containment steps, every Support exchange, reactivation | Diagnose page: “Build a timeline” with “precise dates and timestamps wherever possible” |
| 2. Consent record per number contacted | For each number: the date consent was given, the method (form, call, inbound text), and the subject it covered | Messaging Policy: on written request you must provide “proof of a recipient’s consent and the date and the method through which that consent was obtained” |
| 3. Opt-out log | Every STOP or verbal opt-out, when it arrived, and when your system suppressed the number | Messaging Policy “Revocation of Consent”; voice terms: provide an opt-out mechanism and honour opt-out requests |
| 4. Do-not-call scrub record | Which registry you checked (for US numbers, the National Do Not Call Registry) and when | Voice terms: it is “your responsibility to cross-check” numbers against the applicable registry |
| 5. Opening script and sample messages | The agent’s first spoken lines, and a sample of messages it actually sent, against the registered campaign samples | Voice terms: disclose the purpose of the call and identify yourself at its beginning; 30990: live traffic must match the registered use case and samples |
| 6. Traffic shape | Calls and messages per hour, per originating number: attempts, unanswered share, average call duration | Voice terms: no “high volume of unanswered outbound voice call attempts from a single originating phone number” or “low average outbound voice call duration” in a month |
| 7. Example SIDs | Call SIDs and Message SIDs for the traffic in question; three or more for filtered messages | 30002 page: include the affected Message SIDs; 30007 page: “3 or more examples” |
| 8. Impact, root cause and corrective actions | What was affected (numbers, services, customers, cost from Usage Summary), why it happened, and the specific changes, each with a date | Diagnose page: “Assess the impact”, “Identify the root cause” and “Define preventative and corrective actions” |
Two cautions on item 5. Whether you must also say the caller is an AI depends on where you and the called person are; that is a question for your own counsel. And if your agent writes every SMS fresh, item 5 is often where a campaign suspension starts: live traffic drifts from the registered samples. Our A2P 10DLC guide for AI SMS agents covers registering the bounds the model writes inside.
The sentence to carry into any reply: the fastest Twilio reactivation is the one where every question is answered in the first reply, with evidence attached. Twilio’s Engage page adds: “You are also responsible for keeping Support informed as you complete each step to avoid delays in the reactivation process.”
What to do in the next 7 days while Twilio reviews the account
Days 1–2: finish containment and send the first reply. For compromise or inflated traffic, follow the Contain phase and tell Support as each step is done. Twilio’s illustrative timeline on the Diagnose page runs from first spike to reactivation in under 24 hours, after the customer sends “evidence of remediation (rate limiting and geo blocking)”. Treat that as a best case. The Twilio pages cited here give a clock only for billing reactivation; for fraud and policy reviews they describe steps, not a turnaround time.
Days 2–4: fix the traffic, not the paperwork. For a campaign suspension, the 30990 page’s steps are: read the suspension reason, correct the underlying issue, make live traffic match the registered use case, description, samples and consent flow, and resolve any Brand suspension first, because “all campaigns on that Brand remain suspended until the Brand issue is addressed.” For a toll-free rejection, the 30032 page says the edit window is “seven days from the initial request”.
Days 3–7: build resilience for compliant traffic. A second carrier path for voice is sound engineering; our walkthrough on building failover into an AI voice agent starts at that layer, the SIP trunk. It protects legitimate calls from an outage. It is not a way to keep sending the traffic that caused the suspension.
Throughout: know what is still billing. Twilio’s zero-balance article says recurring charges continue while suspended “(like phone numbers, Interconnect, SIM Cards, Campaign Fees, Support Plans etc.)”. Its phone-number article works an example: 2 numbers suspended with zero balance for 2 months produce 6 number charges in the month of reactivation (2 per suspended month plus 2 for the current one). Releasing a number stops its charge, but releasing and repurchasing numbers to dilute their reputation is what Twilio’s carrier-penalties article lists as “Messaging Program Evasion”, with a $1,000 fine.
Why AI calling campaigns trip Twilio’s rules faster than human teams
None of Twilio’s rules are AI-specific. They describe a traffic shape, and an unattended agent changes that shape faster than a person can. Twilio’s help article on maintaining a positive caller reputation gives the practical lines.
| Twilio’s published line | Where it is written | How an AI campaign usually crosses it |
|---|---|---|
| No “high volume of unanswered outbound voice call attempts from a single originating phone number” in a month | Voice terms | One caller ID carrying the whole list because the agent can dial all night |
| No “low average outbound voice call duration” in a month | Voice terms | Answering-machine detection that hangs up in seconds, pulling the average down |
| “Ensure the called party hears audio within 2 seconds of the greeting. No silent calls.” | Caller reputation article | Speech-to-speech latency, or an agent waiting for the callee to speak first |
| “Allow at least 30 seconds (5 ring cycles) for the called party to answer” | Caller reputation article | Short ring timeouts set to push throughput |
| Example limit: “Limit calls to a given number to 2 in a single day and no more than 5 in a month” | Caller reputation article | Retry logic that re-dials no-answers with no per-number cap |
| No calls “outside the hours of 8AM to 9PM, local time for the called party” (US TSR, stricter in some states) | Caller reputation article | Calling windows set in the operator’s time zone, or from the area code rather than where the person now lives |
| Consent “for each message subject”; blanket or third-party consent not acceptable | Messaging Policy | Bought or shared lead lists, and agents that drift from the subject the person agreed to |
Twilio gives the 2-and-5 figure as an example and the 8AM–9PM line as a US Telemarketing Sales Rule requirement. Treat both as a floor for US traffic, not a safe harbour, and check each other country’s rules.
The fix that stops a Twilio suspension happening again
Five changes, in the order that removes the most risk first.
- Keep the consent ledger live, not reconstructed. Items 2 to 4 of the RCA pack should be a query you can run any day. The Messaging Policy requires you to retain proof of consent “for as long as needed to meet your legal requirements and at least until a recipient withdraws their consent”.
- Put pacing in software, with hard caps. Per-number call caps, local-time windows and a minimum ring time belong in the scheduling layer, where no prompt change can override them. In Zian that layer is SmartReach AI, which orchestrates channel, message, timing and follow-up pacing; whichever platform you run, that is where Twilio’s example limits should live.
- Separate campaigns and clients into subaccounts. A subaccount can be suspended and reactivated on its own, containing a problem to one client or campaign. Know the limit: Twilio’s error 10001 page says a suspended parent account also suspends its subaccounts, so isolation runs downward only.
- Add a spend circuit breaker. Twilio’s own Usage Triggers article shows a subaccount suspending itself when a daily trigger fires, with an example trigger of $30 a day. Two warnings from it belong in your runbook: “Twilio will not alert you when a subaccount is suspended by the REST API”, so send yourself the alert; and set the threshold above your normal number-renewal charges or the breaker will trip on the day your numbers renew.
- If you run campaigns for clients, own their compliance. The AUP says “Customer is responsible for its End Users’ compliance”, and Twilio’s carrier-penalties article says an ISV “is responsible for its End Users and would be considered the ‘content provider’.” If one client’s traffic breaks the AUP, it is the agency’s account Twilio may suspend.
All of this is buildable in-house, given a telephony developer and a compliance owner. The cost is ongoing hours rather than a project: a consent ledger queried weekly, pacing rules retested whenever the agent changes, and a runbook someone has rehearsed. Zian has run outbound acquisition since 2017, at one point for roughly a hundred businesses in the same vertical simultaneously, which is the scale at which that discipline stops being optional.
When a Twilio suspension is not a Twilio problem
If the notice attaches or mentions a regulator, a law-enforcement request, a subpoena or a consumer claim, call a lawyer who practises telemarketing or privacy law in the called person’s jurisdiction before you reply. Twilio’s own help article on its Voice Services Policy tells customers to “speak with their legal counsel to ensure their voice campaigns comply with the policy.” If a carrier fine arrives that you believe is wrong, Twilio says it “will work with you to appeal if the penalty appears to have been applied in error.” The RCA pack and pacing fixes can run in parallel; the legal question is not ours to answer.
If you would rather the pacing, consent and channel layer belonged to a platform built for autonomous outbound, that is what Zian AI does: sales agents running phone, SMS, email and WhatsApp outreach in 30+ languages, with SmartReach AI™ handling timing and follow-up pacing and private model deployment on customer infrastructure. Zian AI is in partnership-application beta, so there is no free trial and no self-serve signup. Apply For Partnership.

Frequently asked questions
Why is my Twilio account suspended?
Twilio lists four categories: an Acceptable Use Policy violation (including spam and excessive complaints or opt-outs), directly fraudulent or abusive activity (including unusual usage spikes and account compromise), non-payment or a negative balance, and security risks. Check the notification email for which one applies to you. The categories are on Twilio’s Engage: Contact Twilio Support page.
How long does it take Twilio to reactivate a suspended account?
For a billing suspension, Twilio says reactivation typically takes 5 to 10 minutes after payment, per its reactivation help article. For fraud and policy suspensions, the pages cited here describe steps, not a turnaround time.
Can I just open a new Twilio account and keep calling?
Not as a fix. Twilio says closing a compromised account and opening a new one is not recommended unless the root cause is fixed, and its error 30990 page warns that sending similar traffic through another campaign during a review can lead to additional enforcement. Its Messaging Policy also prohibits snowshoeing.
Will I still be charged for my Twilio numbers while the account is suspended?
Yes. Twilio continues to bill recurring charges such as phone numbers and campaign fees during a suspension, and after 90 days suspended your numbers are at risk of being reclaimed, according to its help article on number charges.
Does error 30990 mean my whole Twilio account is suspended?
Not by itself. Error 30990 means one A2P 10DLC campaign is suspended and messaging for that campaign is halted, per Twilio’s error page. If the Console badge reads Active, the account is not suspended.
Can I be fined as well as suspended?
Yes, for messaging. Twilio passes through carrier fines, including a $10,000 T-Mobile content violation fine that follows a warning, $1,000 for evasion such as snowshoeing, and Sev-0 fines of $2,000 ($5,000 for RCS), $1,000 or $500 depending on tier, per its carrier penalties article.
Do I need a lawyer for a Twilio suspension?
Usually not for a billing or compromise suspension. If the notice mentions a regulator, a subpoena or a consumer claim, yes, and Twilio itself tells customers to speak with legal counsel about voice campaign compliance in its Voice Services Policy article.
