A Twilio compliance audit is a systematic review of every configuration, registration, and operational practice in your account that could create regulatory exposure, carrier policy violations, or deliverability problems. Most businesses that have been running SMS or voice programs for more than a year have accumulated at least one compliance gap, whether from a registration that was not updated after a business name change, a number that was added to the account but never assigned to a campaign, or an opt-out handling webhook that stopped working after a code deployment. A quarterly audit catches these issues before they cause harm.
Trust Hub Audit: Registrations and Statuses
The Trust Hub section of your Twilio console is the starting point for any compliance audit. Begin by reviewing your Customer Profile status and confirming it shows Twilio Approved; a Customer Profile in any other state indicates a verification problem that may be blocking other registration workflows. Next, review each registered brand and confirm the status is Approved and that the business name, EIN, and contact information still accurately reflect your current legal entity. If your business has changed its name or reorganized since the original brand registration, you may need to update or re-register the brand. Review each campaign registration and confirm that the use case still accurately matches the types of messages being sent under that campaign. Finally, check that every phone number currently in use for business messaging is assigned to an appropriate approved campaign in the number assignment section.
Phone Number Audit: Coverage and Assignment
Export a complete list of all phone numbers in your Twilio account from the Phone Numbers section, including the number type, country, capabilities, and whether they are assigned to a Messaging Service or campaign. Cross-reference this list against your A2P campaign number assignments, your toll-free verification statuses, and your application code to identify any numbers that are provisioned but either unassigned or actively sending traffic without registration. Numbers that have been provisioned but not used in the past 90 days should be evaluated for deprovisioning, as unused numbers still incur monthly rental fees and can create compliance risk if they were previously used for a different purpose than your current campaigns. If you discover numbers assigned to a campaign with a different use case than their current actual usage, reassign them to the correct campaign before the next send.
Opt-Out and Keyword Handling Verification
Test your opt-out handling by sending actual STOP, HELP, and CANCEL keywords to each of your active sending numbers from a test phone and verifying that the correct responses are received within seconds. Document the test date, the number tested, the keyword sent, and the response received. If any number fails to return a compliant STOP confirmation or HELP response, treat it as a critical finding that must be resolved before that number sends any further business messages. Check that your STOP response message includes only an unsubscribe confirmation without any promotional content, and that your HELP response includes your business name, a support contact method, and opt-out instructions. Verify that opt-out records from STOP replies are propagating correctly to your CRM or marketing platform so that unsubscribed numbers are suppressed in future sends regardless of which channel initiates the message.
Content and Consent Documentation Audit
Review a sample of 20 to 30 recent messages sent from each active campaign and compare them against the sample messages submitted during campaign registration. If actual message content has drifted significantly from the registered samples, particularly in use case type, your campaign registration no longer accurately describes your traffic, which is a carrier policy violation. Review your opt-in collection forms or mechanisms to confirm they include all required disclosures and that the consent collection process is functioning as documented in your campaign registration. Pull a sample of 10 to 20 recent consent records from your database and verify that each record includes the required data points: opt-in date, opt-in method, phone number, and disclosure text. If any of these records are incomplete, fix the data collection process and develop a plan for the historical records gap before the next regulatory review or TCPA litigation demand.
Conclusion
A quarterly compliance audit takes two to four hours and prevents the kind of accumulated compliance drift that turns into a legal claim, a carrier suspension, or a deliverability crisis that takes months to resolve.
