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
This clause establishes the procedural mechanism by which Twilio may unilaterally amend the contractual relationship. The 30-day notice requirement for material changes creates an operational window for users to review modifications before the updated terms take effect, while the continued-use acceptance standard determines when modified terms become binding.
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 →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.

"Twilio reserves the right to modify the terms of this Agreement at any time. Twilio will provide at least 30 days' notice of changes that materially alter your rights or obligations. Your continued use of the Services after any modification constitutes your acceptance of the updated Agreement.— Excerpt from Twilio's Twilio Terms of Service
(1) REGULATORY LANDSCAPE: Unilateral modification rights with deemed acceptance through continued use are common in cloud service agreements. In EU/EEA jurisdictions, material changes to commercial agreements may require affirmative consent or longer notice periods under applicable consumer or contract law, particularly for terms that affect price or core service characteristics. (2) GOVERNANCE EXPOSURE: Medium. The 30-day notice period for material changes provides a limited window to evaluate and respond to changes that could affect compliance posture, pricing, or operational requirements. (3) JURISDICTION FLAGS: EU member state contract law in some jurisdictions imposes minimum notice periods or affirmative consent requirements for material term changes in ongoing service agreements. UK consumer contract regulations may also apply where applicable. (4) CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers should negotiate longer notice periods for material changes and, where possible, contractual stability periods for pricing. Vendor management programs should monitor Twilio's Terms for updates within the 30-day window. (5) COMPLIANCE CONSIDERATIONS: Legal teams should establish an alert mechanism for Twilio Terms of Service updates. When material changes are announced, a review of the impact on existing compliance posture, data processing arrangements, and operational procedures should be completed within the notice period.
