Alphanumeric Sender ID prefixes for SMS
A Sender ID is a unique Value or E.164 formatted mobile number that shows in the “from” field of your text messages on your mobile phone
Alphanumeric Sender ID allows you to set your company name or brand as the Sender ID when sending one-way SMS messages to supported countries. Alphanumeric Sender IDs may be up to 11 characters. Accepted characters include both upper- and lower-case ASCII letters, the digits 0 through 9, and space: A-Z, a-z, 0-9. They may not be only numbers.
Improved brand recognition: Because recipients see your name with every SMS sent, using a recognizable Alphanumeric Sender ID reinforces your branding.
Increased open rates: As cases of spam and fraud increase, being able to easily identify the sender is a key factor in whether recipients decide whether to open a message. If the sender is an international or unfamiliar number, the chance of the message being opened is next to none. With Alphanumeric Sender IDs, recipients immediately recognize the sender and know the message is legitimate. As a result, they are up to 80% more likely to open the message.
When a recipient receives a message from any provider or bank etc., a sender ID along with a prefix is displayed in the message inbox. For example- VM-INDUSB, AX-ADHAAR, VK-BAJAJF, and QP-FLPKRT and many more
The prefixes VM, QP, etc. are displayed because SMS is sent in huge numbers via bulk SMS. SMS providers follow rules framed by the Telecom Regulatory Authority of India (TRAI) and according to TRAI rules, Sender ID should be restricted to 6 characters. (E.g VA-ViCARE)
So when you receive an SMS like VM-ICICIB, it means the SMS has come from Mumbai SMS Gateway with Vodafone as operator and Icici Bank would be the Sender.
Sender IDs represent the company name of any sender. Mostly we can see Sender ids in the Transactional SMS route. One can use unlimited Sender IDs once they activate their SMS account with any Operator DLT portal in India.
The following are the list of SMS prefixes and their explanation
When you receive an SMS from "VM-LOCALM" - This SMS was delivered by Vodafone Mumbai. "JD-383022" - would then be Promotional SMS by/from Jio Delhi.
