Toll Free A2P SMS Verification - Twilio Numbers

What do you need to know? 

The messaging industry is making changes to the message volumes that can be sent over an unverified Toll-Free number. This is part of the process to verify all Toll-Free numbers and align sender visibility with the Short Code and 10DLC messaging channels. 

On April 1, Twilio will apply the following industry-wide thresholds for messaging sent over Restricted and Pending Toll-Free numbers will be applied:


  • Daily limit: 500 messages 
  • Weekly limit: 1,000 messages
  • Monthly limit: 2,000 messages


  • Daily limit: 2,000 messages 
  • Weekly limit: 6,000 messages
  • Monthly limit: 10,000 messages

These limits aren’t applicable when a Toll-Free number is already verified. 


What do you need to do?

If you have unverified Toll-Free numbers that send messaging traffic over the new limits, please submit these numbers for verification as soon as possible. If you have a large inventory of numbers, please note that you can only register up to 5 toll-free numbers per account. When registering, select the 5 most important numbers for your messaging campaign. 

If you are not currently exceeding these thresholds, we strongly encourage you to register your Toll-Free number(s) as this can help to increase your delivery rate and reduces the potential for messages to be filtered by the wireless carriers. Registration is required for all Toll-Free numbers sending messages to Canada as well.


How do I register?

  1. Complete Business Registration via the Trust Center  (step 1 in this help article) if you have not already done so, and ensure your account status is carrier approved.  
  2. Complete the Toll Free Verification form which can be found under Numbers > Trust Center. Then select “Use” and scroll to the bottom of the page. There are no costs associated with this registration

Once submitted, the verification process can take up to 2-3 weeks to complete. Keep in mind, you’ll experience verification delays if you omit any information. During this time, your Phone Numbers are moved to a ‘pending verification’ state that adjusts the messaging limits while your submission is reviewed.


What if you don’t take action?

On April 1, 2023, messages sent via Toll-Free numbers that have not been Verified will be held to the messaging limits referenced above. If they exceed the limits, they’ll be blocked. Using additional Toll-Free numbers (snowshoeing) to exceed these limits isn’t allowed and will result in the same block.
