We provide Alphanumeric Brand Sender ID or Masking Sender Name for Corporate Bulk SMS. Generally we provide one fixed default sender id for each user account. By default all user and reseller account assign with none-masking or fixed numeric sender id. If any company or organization need to send sms with their own brand name sender id, then they need to submit Masking Approval Letter from our Documentation menu. For Brand name sender id it's take up to 3-15 working days to verify and approve your brand name sender id from the operator.

An alphanumeric sender can maximum 11 character and can't use any space on sender name. Brand name sender id doesn't support CDMA (CityCell, Bangladesh) operator.
