How is a Sender ID useful?

A Sender ID uniquely identifies your business and helps customers remember your brand. 

Why is registration required?

Some countries require that you register your Sender ID. These countries have a restriction that only allows A2P messaging registered with network operators. Likewise, registering your Sender ID in advance increases the delivery rate of your messages and reduces the chances of getting blocked by carriers.
