You might be receiving SMS codes like AX-Airtel wondering what’s it?

Recently,SMSs from Banks, Service Providers, Companies have started prefixing something like PX, AX, …etc. What’s all this!!??

According to new TRAI regulation, bulk SMS providers have 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: MYTODAY sends an SMS to you using bulk SMS provider located at KARNATAKA which uses Airtel. You will receive it as AX-MYTODAY. 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
