SMS Sender ID: What prefixes like VM, AD etc. mean in Bulk SMS’ I receive?

Bulk SMS Regulation Background

Little do many know the present DNC regulations in India have a background. Telecom Commercial Communication Customer Preferences Regulation, 2010 are built on and preceded by Telecom Unsolicited Commercial Communications Regulations, 2007. When the initial regulations of 2007 were put in place, there was no common standard of Sender-ID (the from name) in Bulk SMS’ that were sent. This meant, SMS’ would be sent with Sender ID as literally anything, e.g. 57333, HelloWorld or any other such name.  This made it difficult for regulatory authorities to determine the origin and sender of SMS’. So there was really no way of tracking the sender of SMS’ except detailed deep dive into CDRs (which was a tedious process).

Welcome, SMS Prefix

c2008, on 10th December, the TRAI called it time enough. And tBulk SMSold all bulk SMS senders to fall in line. And that meant mandating the telecom operators (the entry point of SMS’ into the telecom world). What did they say? They said

  1. SMS sender ID’s in India would be of total 9 characters at the maximum.
  2. These will be of the format **-****** (nine characters, first two characters to be alphabets and third, a hyphen or dash and the last 6 characters again alphanumeric)
  3. The First Two Characters, would be First Character denoting the Operator who is originating the SMS, the Second Character denoting the telecom circle.
  4. The last 6 characters being alphanumeric characters for the name of the sender. For example, Phonon, CitiBk, HDFCBk, Indigo, AmExBk etc.
