What best practices need to be performed for bulk SMS service?

Here are the best practices that need to be followed for bulk SMS messaging;-


  • ID should be such that it either defines your company name (eg Flipkart) or your content (eg VERIFY for OTP).
  • ID cannot be a person's name or related to government authorities/firms, banks, the stock market, etc. For eg (SBIONL,  IRCTC, LICIND). If you still wish to use one, you or your client need to provide us with a letterhead signed by the organization stating that you are allowed to use their Sender IDs.
  • For stock market messages, your user must be registered with SEBI and should be able to provide a SEBI certificate.


  • Any kind of promotion, marketing, sales, offers, or invitations can only be sent through a transactional route or to DND numbers only if the recipients are your registered users.


  • The message should share proper information and not contain any spam content or keywords belonging to the category. For eg. greetings, personal messages,  etc.
