Toll-free verification for US/CA toll-free (+18xx) numbers imported to Sakari via number provider integration (e.g., Twilio, Aircall) is not handled by Sakari.
Numbers of this type must be attached to a toll-free verification approved by the original provider.
US SMS carriers may block messages sent from imported toll-free numbers that are not associated with an approved verification, and you will be charged for those messages.
