You may have heard US mobile carriers have recently changed their policies and will now require that all Toll-Free Numbers (TFNs) complete a registration process.

What does this mean for you?

All text messages from US Toll-Free numbers will now need to be pre verified by all US carriers. Non-verified message traffic will be subject to filtering and message volume limits. In addition, messages to Canada will not be permitted without a pre verified US Toll-Free number or Canadian Long Code.

Currently, messaging traffic to the United States and Canadian mobile phones is supported with the use of dedicated virtual mobile numbers provided by Burst SMS. 

  • USA accounts are provided with a US Toll-Free number 
  • Canadian accounts are provided with Canadian Long Codes
  • For accounts in other regions sending messaged to the USA please contact us for support 

Message Volume Limits

Going forward, mobile carriers will also apply industry-wide thresholds for messaging sent over any unregistered Toll-Free Number:

  • Daily limit: 2,000 text messages
  • Weekly limit: 12,000 text messages
  • Monthly limit: 25,000 text messages

Canadian Longcode Limits

A Canadian Long Code number is a 10-digit phone number that is supported by all major carriers in Canada. These numbers do not require pre verification however are subject to volume limits of 2,000 messages in a day.

 If you would like to send more than 2,000 messages in a day, please Contact Us and we would be happy to take you through your options.

  • Get rich quick schemes (Work-from-home programs, Risk investment opportunities, Pyramid schemes)
  • Debt forgiveness (Third-party debt collection, Debt consolidation, Debt reduction, Credit repair programs)

  • Phishing, fraud or scams
  • Deceptive marketing (Third-party lead generation services)
