Quick answer
To get a masking sender ID in Bangladesh, pick a sender name of up to 11 English letters or numbers, submit it with your NID and a valid trade license through your SMS provider, and wait for the mobile operators to approve it, usually within a few working days. Registration is free with Amar SMS, and masking SMS then costs from ৳0.49 per SMS.
Key takeaways
- Sender name: up to 11 English letters or numbers, no spaces.
- Documents: NID and a valid trade license. Schools may also need an authorisation letter.
- The mobile operators approve the name, usually within a few working days.
- Registration is free with Amar SMS; you pay only for SMS sent (from ৳0.49).
- Until the name is approved, you can already send non-masking SMS.
What is a masking sender ID?
A masking sender ID is the name that appears instead of a phone number when your customers receive your SMS, for example “AmarShop”. It makes messages recognisable and harder to fake. Learn how it compares with regular SMS in masking vs non-masking SMS.
Rules for choosing your sender name
- Up to 11 characters. “AmarShop” (8) works; “AmarShopOnline” (14) is too long.
- English letters and numbers only. No Bangla, spaces or symbols.
- Match your business. Use your brand or business name as it appears on your documents, or a clear short form of it.
- Don't imitate others. Names that look like another company, a bank, a mobile operator or a government body are likely to be rejected.
| Sender name | Likely result | Why |
|---|---|---|
| AmarShop | OK | Matches the brand, 8 characters |
| ABCBank | OK if you are ABC Bank | The name must belong to your business |
| Amar Shop | Change it | Contains a space |
| AmarShopBD24x | Change it | 13 characters |
| GovtNotice | Likely rejected | Looks like a government body |
Documents you need
| Document | Who needs it |
|---|---|
| NID number and a clear scan or photo | Everyone opening an account |
| Valid trade license | Everyone applying for a masking name |
| Authorisation letter on letterhead | Educational and some other institutions |
