What is the meaning of prefixes like BP, DM, BW etc. in SMS?
When a receiver receives a message from any provider or bank etc., Sender ID along with a prefix is displayed in the inbox. For example- BP-MSGWOW, DM-Google, BW-Amazon, and VM-Redbus etc.
The prefixes BP, BW etc. are displayed because SMS are sent in huge numbers via bulk SMS. SMS providers follow rules framed by Telecom Regulatory Authority of India (TRAI) and according to TRAI rules,
- Sender ID should be restricted to 6 characters. (E.g. BP – MSGWOW)
- The prefix has a specific meaning i.e. the first character of prefix displays the operator name:
|Aircel, Dishnet Wireless||D|
|BPL Mobile/Loop Telecom||L|
- The latter character represents the location of the operator through which the message is received:
|Jammu & Kashmir||J|
