Twilio can change the terms of service and will give at least 30 days notice for material changes; continuing to use the service after changes means you have accepted them.
This analysis describes what Twilio's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
The agreement authorizes Twilio to modify terms unilaterally with as little as 30 days notice for material changes, with continued use constituting acceptance, which means customers' contractual rights can change without requiring affirmative agreement.
Interpretive note: The enforceability of deemed acceptance through continued use for material changes may vary in EU/EEA and UK jurisdictions, which may require affirmative consent.
The updated terms establish a different dispute resolution process for customers domiciled or registered in Mexico. Previously, Mexico was subject to the standard arbitration venue clause routing disputes to San Francisco, California. Under the revised agreement, Mexican customers must first engage in good faith negotiations with Twilio's senior representatives for 30 days; if unresolved, disputes proceed to binding arbitration under Centro de Arbitraje de México (CAM) rules, conducted in English in Mexico City before a sole arbitrator. The agreement also explicitly states that Mexican consumer protection law (Ley Federal de Protección al Consumidor) does not apply to the commercial relationship between the parties. Mexico-domiciled customers should review the updated dispute resolution procedures and understand that consumer protection law carve-out before continuing use.
View change record →The updated terms establish two new regional service entities: CISA Telecomunicaciones for Mexico and Teravoz Telecom for Brazil, meaning customers in those jurisdictions will contract with the local entity rather than Twilio Inc. The agreement now permits orders to be placed through Twilio's online self-service purchasing workflow in addition to traditional written order forms, streamlining how purchase terms can be documented. The updated language also removes the prior commitment that Twilio will not materially decrease overall service functionality, replacing it with a general statement that services may change over time without specific protections on functionality levels.
View change record →The updated terms now route Twilio service agreements for Mexico and Brazil customers to new regional entities rather than Twilio Inc., which may affect service delivery, dispute resolution venue, and applicable local law. The definition of Order Form was expanded to explicitly include self-service online purchases, clarifying that terms negotiated through Twilio's account interface carry the same contractual weight as traditional executed agreements. The terms also removed language stating that Twilio would not materially decrease overall service functionality, replacing it with a simpler statement that services may change over time, which narrows the operational commitment Twilio makes regarding service stability. You can review the separate agreements that now govern your use based on your regional location.
View change record →Added carve-out for updates resulting from legal/regulatory/telecom provider changes; specified notice must be 'written'; clarified notice timing relative to effective date; added explicit statement that continued use constitutes acceptance and is binding.
View full change record →Added explicit 30-day notice requirement for material changes (previously only said "notice of material changes"), replaced "material changes" with more specific "changes that materially alter your rights or obligations," and removed the conditional instruction to stop using Services if disagreeing.
View full change record →Business customers and developers are bound by updated terms if they continue using Twilio after the 30-day notice period, meaning pricing, data practices, and other key terms can change with limited notice and without requiring explicit re-acceptance.
