Phone Number Regulations

Phone Number Regulatory Requirements For Customers

Both Twilio and our customers must adhere to local phone number regulations. To help you comply with these regulations and minimize the risk of disruption to your phone numbers, we maintain an up-to-date, country-by-country guide of phone number regulatory requirements.

Local regulations often require providing adequate identity documentation to carriers or a local enforcement agency. To avoid urgent escalations from regulators, we urge you to provide the required information for each country.

Read our Frequently Asked Questions (FAQ) or our Getting Started Guide for additional information. Or take a short tutorial, “International Number Regulations for Global Use Cases.” For detailed information about important milestones for your phone numbers and regulatory compliance, please review our 2019 timeline.

For the benefit of all our customers, these guidelines are provided to help you comply with applicable requirements and to help ensure Twilio's platform remains compliant with global telecommunications ecosystem requirements. These guidelines represent our current understanding of common compliance requirements generally applicable to Twilio and its customers, and do not constitute legal advice. By posting these guidelines, Twilio makes no assurances regarding the legal compliance of your application built using our APIs. You are expected to understand and abide by all compliance obligations applicable to your specific application. You should check these pages regularly for updates as telecommunications ecosystem requirements continue to evolve and change, and the information below may be updated or changed without notice.
