Toll Free SMS Registration Requirements

Effective November 8 2023, all Toll-Free numbers must be verified before they can be used for sms messaging in the U.S. and Canada. As of that date, Toll-Free numbers will be blocked from messaging until they've been submitted for verification.

Toll-Free Message Verification for US/Canada

Toll-Free Verification is required for sending outbound SMS messages over Toll-Free phone numbers to US and Canadian subscribers.

These requirements are consistent with industry-wide, global moves to require registration for all A2P messaging traffic which enables a level of trust by verifying the identity and intent of the sender. Consumers are more likely to trust that a call or text is legitimate, increasing engagement.

Status Traffic Limits More Information

Not Submitted or Rejected

Traffic will be restricted and SMS messages won't be delivered.

Starting on November 8, 2023, ALL Restricted traffic will be blocked in the US.

Pending Verification

Sending Limits (not guaranteed)

Daily: 2,000 message segments

Weekly: 6,000 message segments

Monthly: 10,000 message segments

Once verification has been submitted to our Carrier Partners, your number(s) are moved into a Pending Verification status, which allows for daily sending volumes in the US, but subjects your traffic to tighter message filters while verification is processing.


3 SMS segments per second by default, but can be increased by request.

Upon a successful review of your verification submission and carrier approval, your verified numbers will have full access to A2P sending, and a greatly reduced risk for message filtering on Toll-Free traffic towards all major networks in the US and Canada, as long as you adhere to your stated use case and all applicable policies and regulations.

Verification Process

To begin the verification process, please contact our support team with the following information. Carrier approval will take approximately 1-2 weeks from submission.
