Sender ID regulation for SMS

A Sender ID is the name or number displayed to the recipient when they receive an SMS. While the SMS channel allows you to choose your Sender ID, it’s important to note that each destination country has its own regulations regarding Sender IDs, and these rules may change over time. Below is an overview of the possibilities for a few countries:

• The Netherlands

  • Both numeric and textual senders are allowed.

  • Textual senders must be between 3 and 11 characters (applies to all countries).

  • Numeric senders can be up to 15 characters long (including country code, e.g., 0031).

  • No special registration required.

• Belgium

  • All sender names are overwritten by the shortcode 8850.

  • No special registration required.

• France

  • Textual senders are supported, with 'STOP 36047' automatically added to the SMS content.

  • To remove the STOP message, a special shortcode is necessary. Contact support@cm.com or your CM.com contact person for assistance.

  • No special registration required.

• Germany

  • Both numeric and textual senders are supported.

  • No special registration required.

• UK

  • Both numeric and textual senders are supported.

  • No special registration required.

• South Africa

  • All sender names are replaced with a local number.

  • No special registration required.

• USA & Canada

  • Messages must be sent from a local number, available for purchase through the CM platform. Contact support@cm.com or your CM.com contact person for assistance.

  • Registration is required.

In all countries, the sender name should be meaningful to recipients and reflect the sending company. Generic sender names (e.g., 'Info', 'Support') may be filtered as SPAM or smishing.

When composing your message in the web interface, you can select or create your own Sender ID. In some countries (e.g., Belgium), a shortcode selection is mandatory because delivery via an alphanumeric Sender ID is not possible.

⚠️ Always ensure compliance with the latest local regulations. The rules outlined in this article may become outdated, so it's crucial to verify current regulations if you're uncertain.
