Create a Sender ID
What is a Sender ID?
A Sender ID is a set of alphanumeric characters that represent the identity of the sender. It can be a mobile number (in the case of a regular message) or a company brand. Let’s take an example of the transactional message you receive from a bank when you withdraw the money. The Sender ID here would be either the name of the bank or any alphanumeric characters from which you would have received the message.
Sender ID Format
Different countries have different guidelines for companies to create Sender IDs. For example, in India, TRAI has the following guidelines:
- Promotional Sender IDs should be in the format of AY-1ZZZZZ. The AY here is a combination of operator and area code, 1 represents the category as listed in NCPR, and ZZZZZ is the five-digit code given by the access provider.
- Transactional Sender IDs should be in the format of AY-A2DCE. The AY here is again a combination of operator and area code, and A2DCE represents the five-digit alphanumeric code the customer chooses.
You can refer to our document for more information on global guidelines before creating a Sender ID.
