The Meaning of SMS Codes Like TD-Google AD-mCampus AD-SBIINB You Have Receiving from Banks, Service Providers, Companies ETC.

You have been receiving SMS from Banks, Service Providers, Companies and many other recognized organizations, institutes that have started prefixing something like TA, AD, ID, AT, VK…etc. What’s all this after all!!?

Normally these SMSs originates from a Bulk SMS provider where they use minimum 9 digit Alpha-Numeric characters as “Sender”. But there were some security risks in this method. They can give a phone number as “Sender” & it appears as that person at the recipient end. Basically there was a chance to send SMSs by any other different person or fake identity with the same number to fool someone!

But the new TRAI regulation insisted bulk SMS providers to restrict the “Sender ID” to minimum 6 characters. Other three characters should be used to specify who is the bulk SMS service provider & where it’s originated from. Say for example: SBI bank(SBIINB) sends an SMS to you using bulk SMS provider located at Delhi which uses Airtel. You will receive it as AD-SBIINB. 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:
