What is masking SMS?
In Bangladesh, masking SMS means a text message that arrives from a brand name, such as "MYSHOP", rather than from a phone number. That name is the sender ID or mask. Non-masking SMS arrives from an ordinary number.
| Masking SMS | Non-masking SMS | |
|---|---|---|
| Sender shown | Your brand name | A phone number |
| Setup | Mask must be registered and approved | Quick to start |
| Replies | Usually not possible | Customers can reply |
| Trust | Looks official | Can look like spam |
Masks are applied for through a licensed SMS gateway, which registers them with the mobile operators under the country's telecom rules.
Why does it matter for sellers in Bangladesh?
Not every customer uses WhatsApp, and some have no mobile data when the courier calls. SMS still reaches every phone. For order confirmations, OTPs and delivery notices, a masked sender ID tells the customer the message really comes from your shop, which matters when fraud messages are common. Many shops use WhatsApp as the main channel and SMS as the fallback.
Example
A shop registers the mask "DESHIBAZAR" with its gateway. When an order ships, customers without WhatsApp get: "DESHIBAZAR: Your order #1045 is with the courier. Pay ৳1,250 on delivery. Call 01XXXXXXXXX for help."

Frequently asked questions
How do I get a masking sender ID?
Apply through a licensed SMS gateway. You usually submit the brand name you want plus business documents, and the gateway gets it approved with the mobile operators under Bangladesh's telecom rules.
Is masking SMS more expensive than non-masking?
It is usually priced higher. Rates vary by gateway and change over time, so ask your gateway for current prices.
Can customers reply to a masking SMS?
Generally no, because the sender is a name, not a number. Add a phone number or WhatsApp link in the text if you want replies.
