To protect users from fraud, French network operators are now actively blocking messages that use outdated, generic, or improperly formatted Sender IDs (the name that appears as the sender on a mobile phone).

We want to ensure your SMS campaigns continue to run without interruption.

🛠️ The New French Rules (Strict Formatting)

If your Practice wants to send messages to French mobile numbers, their Sender IDs must adhere strictly to these alphanumeric criteria:

• Length & Characters: Maximum of 11 characters. Only standard letters (A–Z) and numbers (0–9) are allowed.
• No Spaces: Spaces are completely prohibited.
• No Punctuation or Symbols: Dashes, underscores, dots, or symbols are strictly banned.
• No Accents: Accented characters (e.g., é, à, ç) cannot be used.
• No Generic Terms: Words like ALERT, INFO, or APPOINTMENT will be automatically blocked. The ID must clearly match their registered company, clinic, or brand name.
• Proof of Identity: Clients must have official documentation (like company registration or trademark info) ready to provide if requested by the regulator.

To ensure your SMS campaigns are not blocked or labelled as “Unverified” you must register your Sender ID(s) now.

How to Register

You can submit your information in one of two ways:

• Option 1 (Quickest): Complete the Australian Sender ID Registration Form.
• Option 2 (Offline): Fill out the attached Excel Registration Form and email it back to us at:

1. Australian Sender ID Registration Form (Excel): Use this if you prefer to gather your data offline before submitting.
2. Letter of Authorisation (LOA) Template: Mandatory if you are sending SMS on behalf of another entity (e.g., as a reseller or agency). This must be printed on the Sender ID owner’s letterhead and signed.
3. Additional Support Information (PDF): A detailed guide on the registration process, including how to verify your use case if you do not have an Australian Business Number (ABN).

1. Identity Verification: Your named Authorised Representative will receive an email via DocuSign to validate their identity.
2. ACMA Submission: Esendex will submit your application to the Australian register.
