SMS Operator Codes

You have been receiving SMS codes: TA-ICICI, AX-Airtel…and wondering what’s it?

Recently, from almost a month SMSs from Banks, Service Providers, Companies have started prefixing something like ID, AT, VK…etc. What’s all this after all!!? Here I am to explain you what it is! Normally these SMSs originates from a Bulk SMS provider where you can use 11 digit Alpha-Numeric characters as "Sender". But there were some security risks in this method. I was able to give a phone number as "Sender" & it appears as that person at the recipient end. Basically there was a chance to send SMSs as a different person! I was actually using this to fool my friends.

But the new TRAI regulation insisted bulk SMS providers to restrict the "Sender ID" to 8 characters. Other three characters should be used to specify who is the service provider & where it’s originated from. Say for example: HDFCBANK sends an SMS to you using bulk SMS provider located at Tamil Nadu which uses Airtel. You will receive it as AT-HDFCBANK. First character specifies which service provider the message is being originated & the second character specifies from which location it’s originated. Here is the table which has details of these SMS codes:

Service Provider Codes:

Aircel, Dishnet Wireless	D
Bharti Airtel	A
BSNL	B
BPL Mobile/Loop Telecom	L
Datacom Solutions	C
HFCL Infotel	H

So, combination of these two constitutes the first two digit of Sender followed by an hyphen (-) & actual sender name.
