SMS Guidelines for Belarus

MCC: 257
Dial Code: 375

Alphanumeric Sender IDs are supported with registration. Alpha numeric Sender ID registration is required.

The use of generic Alpha Sender IDs is not recommended as these can be rejected or blocked by local Operators. Alphanumeric Sender IDs should be directly related to the message content.

Please make sure to always refer to our Acceptable Use Policy for Messaging.

For more information on Alpha Sender ID registration kindly reach out to alpha_sender_id@telnyx.com.
