US Toll-Free Phone Number Registration


As of late November 2022, the average carrier processing time to review a toll-free submission is 5 business days. Please do not run any messaging campaigns for at least five business days after submission.


What is Toll-Free Verification?

The toll-free verification process is free of charge. It pre-qualifies messaging traffic as 'verified' with our downstream peers, which helps to increase message deliverability on the toll-free number.

Verification is not whitelisting, so approval doesn’t guarantee that you won’t experience any blocking. However, as long as the sent messages align with what's stated on the approved verification application, we can work with our peers more swiftly and ask for a block to be removed.

What are the differences between Verified, Pending, and Restricted numbers?

The Toll-free Aggregator has created 3 Classes of Service to classify verification status: Verified, Pending Verification, and Restricted.

  • Verified: Verified numbers have gone through the toll-free verification process and were approved. Their traffic is subjected to limited filters. If traffic does trigger any filters that specific content will be blocked but the number will not be automatically blocked.
  • Pending Verification: Pending Verification numbers have submitted a toll-free verification application, and are currently awaiting a response from the aggregator. They can send at a lower throughput than verified numbers, but higher than restricted numbers. Blocking can be applied to individual content or there can be an automatic block of all traffic from the number. These numbers will remain in this pending state until a decision has been made on verification status.
  • Restricted (aka Unverified): Restricted numbers have either 1) not submitted a verification request or 2) have had their application denied. These numbers are subject to the highest amount of filtering, and numbers in this state will automatically get shut off if any spam or unwanted traffic is detected. 
    • Daily Limit: 2,000 messages per day
    • Weekly Limit: 12,000 messages per week
    • Monthly Limit: 25,000 messages per month.


Toll-Free numbers sending traffic to Canadian destinations will need to have their traffic verified or in a pending status or the traffic will be blocked. The above limits do not apply to unverified Canadian traffic.


What does it cost? 

The toll-free verification process is free of charge. 


What are the minimum requirements to get verified?

  • One or more toll-free numbers
  • Verification form completed
  • The use case is not listed on our Ineligible Use Case list
  • A documented/detailed opt-in process (a screenshot and/or URL is required for marketing use cases).  See below for examples. 
  • Sakari Terms of Service and Carrier Best Practices (CTIA guidelines) are being followed


How long does it take to be approved?

As of late September 2022, once the Sakari team receives your form, it will be submitted within 1-2 business days. Upon submission, carriers are currently processing requests in 4-5 weeks


What other options do I have?

If you prefer to message from a United States Local phone number (e.g. 415, 206, 919), we can set that up on your account.  Please note that businesses messaging on local phone numbers have a separate registration process called 10DLC that must be completed.  10DLC registrations typically are approved in 1 business day.

Toll-Free Messaging Best Practices

Toll-Free messaging users must adhere to the following standards:

  • Obtain clear opt-in from your recipients before sending them messages (the opt-in does not need to be via text messaging)
  • Provide easy ways for your users to opt-out of messages
  • Maintain a very low opt-out (STOP reply) rate from your recipients
  • Use shortened, branded URLs for the highest deliverability levels when sending links in the message body. Do not use shared URL shorteners (such as popular free URL shortening services) as these are forbidden by US carriers and will result in filtering.  We provide a free of charge URL shortener, you can learn more about that here
  • Do not "load balance" by sending the same or similar messages using multiple Toll-Free numbers. Carriers call this "snowshoeing" and it is specifically targeted for filtering on toll-free SMS.
    • If you have a valid use case for sending the same or similar messages over multiple Toll-Free numbers, please contact Sakari support.
