Twilio Sub-Processors
Last Updated: September 2026
Third Party Sub-Processors
Twilio uses the third party companies below (each, a “sub-processor”) to process personal data (i) on behalf of Twilio customers; (ii) in accordance with customer instructions as communicated by Twilio; and (iii) in strict accordance with the terms of a written contract between Twilio and the sub-processor.
Twilio imposes obligations on its sub-processors to implement appropriate technical and organizational measures ensuring that the sub-processing of personal data is protected to the standards required by applicable data protection laws. Further information relating to sub-processor security measures can be found via the external links below.
Where the engagement of a sub-processor requires the cross-border transfer of personal data, Twilio has performed Transfer Impact Assessments for such data transfer.
Twilio maintains an up-to-date list of the names and locations of all sub-processors below for all generally available services. For services that are not generally available, sub-processors are listed in the product documentation provided with the service. Twilio customers may subscribe to notifications of sub-processor changes to receive updates.
Duration of processing: For each sub-processor below, processing of personal data will be for the duration that the customer uses and continues to use the applicable service(s), and for the retention periods as set out in customer’s agreement with Twilio.
Please note that telecommunications providers used by Twilio are not processors of Twilio or sub-processors of our customers. Additional information about this position can be found here.
