In our day to day life, we all receive a lot of messages to our mobile phones but have you ever wondered about the two characters in front of the six-letter characters sender Id. If you haven’t notice that then continue reading this article.
In the image below, the first two characters AD are the prefix of the six-letter characters (SWIGGY) sender Id.
You will find out whenever you will receive the sender Id messages on your mobile phones. The two characters in front of the sender Id are the prefix i.e ‘AD’. These two characters are automatically generated by the telecom operator.

A = is the telecom operator name.
