SMS Sent from International Long Codes to the UK Will Be Blocked

• UK carriers have implemented restrictions on messaging traffic originating from international long codes to UK phone numbers; they consider the use of international long codes for Application-To-Person (A2P) SMS as an abuse of Person-To-Person (P2P) routes.
• Due to these restrictions, in 2023, Carriers began blocking all SMS messaging traffic sent from international long codes to UK phone numbers on the BT and Sky Mobile networks.

• Starting 30th July 2024, all SMS messages sent to the UK via international long codes, regardless of carrier, will be blocked. Going forward, SMS messages sent to the UK must be sent via a domestic UK long code, an Alphanumeric Sender ID, or a short code.

• We plan to support Alphanumeric SenderID and Short-codes in the next 6/9 months.

By 30th July 2024, start using UK long code to replace your international long codes to send A2P messages to the UK:

• Go to Location Settings -> Phone Numbers Tab
• Create a Regulatory Bundle / Address based on the number type you want to buy in the UK and submit it for approval.
• Once approved please proceed to buy a UK number.

If you don’t use an alternative to replace international long codes, all SMS messages sent to the UK from international long codes will be blocked starting 30th July 2024.
