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. The main purpose of this is to inform you about the channel that is being used in order to deliver the messages on your mobile phones.
Therefore in the image above, we have taken an example sender Id prefix i.e ‘AD’, where
A = is the telecom operator name.
D = is the location of the operator.
So, we can now easily say that message has come from AIRTEL, DELHI
These rules have been formulated by TRAI( Telecom Regulatory Authority of India ).
So, let us check the code for Telecom Operator and its Locations.
|Aircel, Dishnet Wireless||D|
|BPL Mobile/Loop Telecom||L|
State codes that signify the origin of the SMS:
|Location of Telecom Operator||Code|
|Jammu & Kashmir||J|
