The carriers responsible for toll-free text messaging in North America mandate verification of toll-free numbers before you can use a toll-free number to send application-to-person (A2P) messages. This change aligns toll-free messaging with 10DLC and short codes, which already have business verification measures in place. The intent is to ensure that message senders on all services are reviewed and that businesses that send messages are documented and verified.
The verification process involves the carrier responsible for verification reviewing the submitted information and either approving or rejecting the application. The process can take up to two weeks.
Irrespective of the volumes of application-to-peer (a2p) messages you intend to send on toll-free numbers, you must verify each toll-free number.
Plivo recommends that you begin sending messages only after a toll-free number has been verified.
How to get toll-free numbers verified
Verified numbers are subject to the least amount of filtering — but that doesn’t mean customers can use them in unapproved ways. All messaging must still comply with best practices for A2P messaging and must not be used for any use case that is not allowed by carriers in the US or Canada.
Once verified, a number does not need to be re-verified for the same use case in the future. If you want to use any given toll-free number for a different or an additional use case, you should submit a new verification request. Failure to do so can be considered noncompliance by the carriers and may result in your messaging services being suspended.
