Bulk Messages(SMS) Codes reference

Ever confused by what does LM-ICICIBNK, VX-Citibank, LM-AxisBank, BT-SBI, AM-Holidays etc. means ??

As per 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............ Code 
Aircel, Dishnet Wireless........ D 
Bharti Airtel....................... A 
BSNL................................ B 
BPL Mobile/Loop Telecom...... L 
Datacom Solutions............... C
