Definition of Sender ID
A Sender ID (also known as a Sender Name or Alphanumeric Sender ID) is a custom text identifier that appears as the sender of your bulk SMS messages instead of a phone number. It's the name that recipients see when they receive your SMS messages on their mobile phones.
For example, instead of receiving a message from an unknown number like 070011000, your customers will see your brand name like CELCOM_AFRICA or YOUR_BRAND as the sender. This is achieved through sender ID registration with Mobile Network Operators (MNOs) and the Communications Authority of Kenya (CAK).
Key Characteristics:
- Maximum 11 characters in length
- Alphanumeric characters only (A-Z, 0-9, underscore, hyphen, or space)
- Must be unique and registered with MNOs
- Requires CAK approval for use in Kenya
