Alphanumeric Sender IDs, Registration process

What is a Sender ID?

Sender ID is the alpha name or alpha-numeric name or number which appears on the mobile phone as the sender of an SMS (It is used to identify who’s sending the message to the recipient). Sender ID can be a number (i.e. a Mobile Phone Number) or alpha-numeric term such as DARBIRD, DARCART.

How is Sender ID useful?

Sender ID is useful in uniquely identifying your business and helps with brand recall amongst your customers.

Why is registration required?

In some countries, there is a specific restriction, where A2P messaging is allowed only when they are whitelisted (registered) with the network operators.

Also, registering your sender id in advance increases the delivery rate of your messages and reduces the chances of getting blocked by carriers.
