Important Information for Sending Text Messages to UK Mobile Numbers via International Long Codes:
If you have recently sent SMS messages to UK mobile numbers using long international codes, please take note of the following:
Starting June 1, 2023, UK network operators will implement a block on SMS messages sent using long international codes.
This decision results from UK network operators considering using long international codes for Application-To-Person (A2P) SMS as an infringement on Person-To-Person (P2P) routes. To adhere to the new regulations, SMS messages destined for the UK must be sent using a local number.
What actions should be taken?
Before June 1, 2023, it is necessary to utilize a local UK number to send Application-To-Person (A2P) messages to the UK. If you are using LC Phone and require assistance procuring an SMS-capable UK number, kindly contact our support team, and we will acquire a mobile UK number on your behalf.
For those who are not using LC Phone, please follow these steps in the Twilio Console:
- Go to Develop > Phone numbers.
- Select Buy a number.
- Set the country to the UK and uncheck the Voice capabilities option.
- This will provide you with a list of available numbers that can be purchased for receiving messages.
If no action is taken, SMS messages sent to the UK using long international codes will be blocked effectively from June 1, 2023.
