  • Promo DND : This type of message and new and illegal and use to send Promotional contents on DND numbers the cost of Promo DND is higher that promotional and Transactional.


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 6 characters. Other three characters should be used to specify who is the service provider & where it’s originated from. Say for example: IDBIBK sends an SMS to you using bulk SMS provider located at Tamil Nadu which uses Airtel. You will receive it as AT-IDBIBK. 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:

Service Provider Code
Aircel, Dishnet Wireless D
Bharti Airtel A
BPL Mobile/Loop Telecom L
Datacom Solutions C
HFCL Infotel H
Idea Cellular I
Reliance Communications R

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