US and Canadian Toll-Free Phone Number FAQ


The average carrier review process is within 72 hours of submission.


Beginning Jan 31, 2024, the industry’s Toll-Free aggregator will block messaging traffic for unverified Toll-Free numbers. 


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.


How do I submit a Toll-Free verification form? 

Verification can be completed directly from the Sender page in Sakari.

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 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. These numbers will remain in this pending state until a decision has been made on verification status.

  Previous Limit Limit starting Jan 31, 2024
Daily Limit (segments) 2,000 0
Weekly Limit (segments) 6,000 0
Monthly Limit (segments) 10,000 0

Restricted (Unverified)

Restricted numbers have either 1) not submitted a verification request or 2) have had their application denied. 

  Previous Limit Limit effective Nov 8, 2023
Daily Limit (segments) 2,000 0
Weekly Limit (segments) 12,000 0
Monthly Limit (segments) 25,000 0

Toll-Free numbers sending traffic to Canadian destinations will need to have their traffic verified or the traffic will be blocked. 


Cost of Toll Free Verification

The Toll-Free verification process is free of charge. 


Requirements to get verified

The minimum requirements to verify your toll free number are:

  • One or more Toll-Free numbers
  • 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?

Currently the average carrier processing time to review a Toll-Free submission is approximately 4 weeks.

Once submitted, your Toll Free number will be pending verification, which will be subject to the sending limits as stated above.

Benefits of a Toll-Free Number

Toll free phone numbers have several benefits compared to local phone numbers: 

  • Higher Rates- Toll-Free Phone Numbers are made for application-to-person (A2P) SMS and offer higher send rates than long code (local) phone numbers.
  • Call Forwarding- All inbound calls can be forwarded to an existing phone number

Alternatives to a Toll-Free Number

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 with 3 business days.

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) see the article here.
  • 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.
