**Important:** Requirements for Sender ID Names:

* **Up to 14 characters:** If the name consists solely of digits.

* **Up to 11 characters:** For names containing text, digits, and/or spaces.

* **Prohibited names:** Misleading names (e.g., POLICE) are not allowed.
  {% endhint %}

* If you are using a custom name (e.g., company name), it must be verified by the Customer Service Office (CSO). After adding the header, you will receive an email confirming that the name is pending approval. **The process takes a maximum of one business day.**
