The notice discloses that Twilio receives telecommunications data from carriers and aggregators including phone type, SIM and carrier history, registration location, account type, and IP address for identity validation purposes, and that these telecommunications service providers function as independent data controllers when processing metadata.

This provision establishes that telecommunications service providers receiving customer data operate as independent data controllers rather than processors, meaning their data handling is governed by their own privacy frameworks rather than Twilio's DPA terms. The telecommunications data categories disclosed include SIM and carrier history and registration location, which are operationally sensitive for identity verification purposes.
The updated Privacy Notice now explicitly discloses that Twilio is subject to FTC investigatory and enforcement powers, clarifying the regulatory oversight applying to the company. The policy also establishes an opt-out right allowing users to prevent disclosure of their data to third parties (other than service providers) or use of data for purposes materially different from the original collection purpose. You can exercise this opt-out by contacting Twilio through the mechanisms described in the privacy notice.
View change record →The updated notice establishes more explicit disclosures of Twilio's Data Privacy Framework certifications and specifies the legal hierarchy governing data processing. Under the revised policy, the DPF Principles now take precedence if they conflict with other terms in the privacy notice. The updated language also clarifies your right to opt out of third-party disclosures (except to service providers acting on Twilio's behalf) and to opt out of uses that materially differ from original collection purposes. You can exercise these choices by contacting privacy@twilio.com.
View change record →The updated Privacy Notice now provides more detailed explanations of how Twilio collects and processes personal data, including explicit definitions of what constitutes personal data and descriptions of direct relationships (when you create an account or opt into communications) versus indirect relationships (when you are a customer of one of Twilio's customers). The revised language establishes that Twilio acts as a data controller and determines how and why personal data is processed, subject to applicable law. The notice states it aims to be transparent about data use and to explain how you can exercise your rights, but the change itself does not modify what data is collected, how it is used, or what rights or controls are available to you.
View change record →Under this clause, personal data including SIM and carrier history, registration location, and account type is received from telecommunications operators and may be shared back with those operators, who function as independent data controllers subject to their own privacy terms rather than Twilio's policies. U.S. account holders may also exercise opt-out rights over CPNI use for marketing by contacting Twilio.

"Telecommunications Data: Communication-related data from operators, aggregators, and carriers - including phone type, SIM and carrier history, registration location, account type and IP address - used to validate whether personal data provided to Twilio matches operator, aggregator or carrier records. [...] Telecommunications Service Providers: Global network of operators, aggregators, and carriers who act as conduits for Customer Content. These providers function as independent data controllers when processing metadata for billing, fraud prevention, or legal compliance.Excerpt from Twilio's Privacy Notice
1) REGULATORY LANDSCAPE: U.S. CPNI regulations under the Communications Act and FCC rules govern the use and disclosure of call destination, location, and configuration data by telecommunications providers. GDPR and applicable national telecommunications privacy laws govern equivalent data in the EEA. The FTC, FCC (for CPNI-related matters), and relevant EU supervisory authorities are enforcement bodies. 2) GOVERNANCE EXPOSURE: Medium. The classification of telecommunications carriers as independent data controllers when processing metadata means that Twilio's DPA and privacy obligations do not extend to those processing activities, creating a gap in the chain of data protection accountability that enterprise customers may need to evaluate. 3) JURISDICTION FLAGS: U.S. CPNI regulations create specific obligations for Twilio regarding call destination, location, and configuration data. The notice provides a separate CPNI disclosure and opt-out mechanism. In the EEA, sharing of SIM and carrier history data may engage national telecommunications privacy laws in addition to GDPR. 4) CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers whose end-user communications data flows through Twilio's carrier network should be aware that carrier-level processing of metadata occurs under the carriers' own controller frameworks, and that Twilio's DPA terms do not govern that processing. Vendor assessments may need to account for this structural gap. 5) COMPLIANCE CONSIDERATIONS: Compliance teams should evaluate the independent controller classification for telecommunications providers against GDPR joint controllership standards, assess CPNI opt-out procedures for U.S. accounts, and review whether data flows to telecommunications operators in specific jurisdictions engage additional national regulatory requirements.
This provision establishes that telecommunications service providers receiving customer data operate as independent data controllers rather than processors, meaning their data handling is governed by their own privacy frameworks rather than Twilio's DPA terms. The telecommunications data categories disclosed include SIM and carrier history and registration location, which are operationally sensitive for identity verification purposes.
Under this clause, personal data including SIM and carrier history, registration location, and account type is received from telecommunications operators and may be shared back with those operators, who function as independent data controllers subject to their own privacy terms rather than Twilio's policies. U.S. account holders may also exercise opt-out rights over CPNI use for marketing by contacting Twilio.
