Your short code may be audited for compliance with carrier guidelines by the CTIA, CWTA or by individual carriers. Furthermore, Twilio proactively audits US and Canada short codes to help you ensure that your campaign is compliant and up to date with industry standards.
If your short code is audited and the campaign is found to be non-compliant, Twilio’s A2P Compliance team will contact you with a list of the identified issues and will let you know how to resolve them. You will typically be given a deadline of one week to resolve any issues, after which point your short code will be at risk of suspension if the issues have not been resolved.
If your short code is suspended by a particular carrier, it will take at least 30 days (and possibly longer) to restore service. Every time a short code is suspended by a carrier, it must go through that carrier’s provisioning process again to be re-approved.
Below is additional information related to common audit violations as well as the expected cure dates for resolution.
