⚠️ Please note: The deadline for registration of Toll-Free US/Canada Numbers has passed. We suggest you complete this registration as soon as possible to protect your SMS experience.
This industry-wide process is jointly managed by Aircall and our suppliers and carriers providing US/Canada Toll-Free numbers. This verification reduces the risk of message filtering on Toll-Free traffic toward all major networks in the United States and many major networks in Canada.
If a Toll-Free number is not verified or if the submitted verification documentation is rejected, outgoing SMS traffic may be blocked for the unregistered Toll-Free number. While submitted verification is pending, outbound SMS traffic will be open.
Unverified Toll-Free outbound sms activity towards US numbers will be limited to:
Daily limit: 2,000 segments
Weekly limit: 12,000 segments
Monthly limit: 25,000 segments
⚠️ Above this limit every additional outbound sms message will be filtered by our provider. Inbound won’t be affected.
Unverified Toll-Free outbound sms activity towards Canadian numbers will be blocked.
This process will not impact inbound SMS traffic or voice services.
If your company has registered numbers for A2P 10DLC, you will be required to submit new information unique to your Toll-Free US/Canada numbers for messaging compliance as A2P 10DLC does not apply to Toll-Free numbers.
Unlike A2P 10DLC, which has requirements for registration based on volume and use case, this registration is required for all Toll-Free US/Canada numbers regardless of messaging volume or use case.

What is a “Segment?”
Aircall, along with the whole telco industry (carriers and providers), count messages in 'segments.' Segments come from the SMS standard that was implemented in the 1990s, and is still in use today.
1 segment is 160 characters (using only a specific range of characters). Longer text messages are combined to appear as single messages even if they contain several segments (up to 1600 characters).
To verify how many segments are in one of your messages, you can find segment calculators online.
