Documents Required and Instructions to Register Your Alphanumeric Sender ID in Bangladesh

Before we begin

Due to regulatory requirements, there is sometimes a need for documents to be signed by customers to ensure that registrations are done on behalf of customers that have the right to use the Sender ID. This serves to ensure that traffic is coming from legitimate sources and minimizes any potential misuse.

This article outlines the documentation requirements for a pre-registration in Bangladesh.
