Bulk SMS Sender ID Codes In India

Like it. Share

One of the most popular and cheapest marketing channels known to us is Email Marketing or as some might refer to it as Bulk email marketing. Have you noticed SMS sender Id prefixes like DM, TA, LM, DZ in Bulk SMS Sender ID Codes? This article explains what they actually are.

Majorly, there are two types of SMS; Transactional & Promotional.

Promotional SMS Vs Transactional SMS

TRAI has notified “The Telecom Commercial Communication Customer Preference Regulations, 2010” classifying text messages as per the intent or nature of content within the text messages. Here is an easy summary:

Promotional SMS is used to send offers, discounts or promotions to new and existing customers. The messages may or may not be solicited by the recipients.Transactional SMS is used to send OTPs, informational messages, booking and order alerts to your registered customers. They should not be intended for marketing.
Messages are only delivered to non-DND numbers and opt-in numbers*Messages are delivered to all recipients, irrespective of their Do-Not-Disturb (DND) status
Promotional SMS can be sent only between 9am and 9pmTransactional SMS are delivered 24×7 with no time restriction
Promotional bulk SMS will be delivered with a random 6-digit Sender ID assigned by the telecom operator
Transactional SMS can be assigned a 6-alpha character Sender ID of your choice. It should correspond with your business or product name.

Can we identify Transactional SMS from a Promotional SMS

One can very easily differentiate a transactional SMS from a promotional SMS based on the Sender-ID it gets delivered from.

All sms will have prefix as LM, MD, DM, etc which are automatically set by the operator delivering the particular message. Because we work with different SMS gateways in India who internally work with multiple operators who may try to send your SMS via the cheapest & best route possible, the prefix is mostly unpredictable. These prefixes are meant to inform the recipient about the channel used in delivering the SMS. Typically, they use this Prefix information to report a DND/NDNC violation to operators.

For example, we receive SMS from our bank, let us take ICICI, when we receive then the sender id would be like this TD-ICICIB. So, here we are discussing on the first two characters of the sender id, that is TDT as in Tata Teleservices, hence this is a Telecom Operator Code and D as in Delhi, hence this is Regional Code.

We have listed major Telecom Operator Codes and Regional Codes to understand better.

“AX-650134” – would be Promotional SMS from Airtel Karnataka.
