Deactivations Resource

This resource retrieves a list of United States phone numbers that have been deactivated by mobile carriers. These phone numbers are no longer in service for the subscriber who used to own that number. Twilio updates the set of available reports daily.

These reports should be used periodically to remove deactivated phone numbers from your opted-in subscriber list. For more information how to use these reports, see the "Handling Deactivated Phone Numbers" Help Center article(link takes you to an external page).

API requests to the Deactivations Resource are free of charge.
