Masked Phone Numbers

Number Masking For Customer Privacy

Connect your customers to drivers, delivery personnel or vendors, without revealing their phone numbers




What is Number masking?

Number masking, as it is colloquially called, is the best way for businesses to safeguard their customers’ identity, and prevent misuse of sensitive information, enabled by anonymisation of customer’s phone number. This solution allows you to connect two parties without revealing either party’s phone number. This also allows you to ensure that transactions happen on your platform and not offline.

How It Works


Driver/Executive gets assigned to a customer

Clicking on the ‘call customer’ button in the app, automatically makes a call to Exotel’s virtual number.


Exotel reaches your server

Exotel pings your server with the driver’s/ executive’s details. Your server returns the corresponding customer’s number


Exotel dials customer number

Exotel connects the assigned executive to the respective customer


Customer number masked

Customer/passenger numbers are masked from drivers/executives as virtual number acts as a bridge between the parties

Advantages of Masked Phone Numbers


Ensure Customer Privacy

Number masking is also the best way to avoid off-platform transactions thereby allowing you to monetize better


Save Cost

Who can use it?

Masked telephone numbers can be used in any industry that requires customers to give their personal numbers.

Typically, E-commerce, last mile companies and cab aggregators use masked phone numbers to connect delivery personnel/cab drivers to customers without revealing the number of either of the parties.

We used to use a traditional PBX system before. But that doesn’t have the capabilities of Exotel’s IVR system. So, we decided to use Exotel for our IVR cancellation system.
