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 or call masking is the best way for businesses to safeguard their customers’ identity, and prevent misuse of sensitive information, enabled by anonymization of customer’s phone number. This solution allows you to connect two parties without revealing either party’s phone number. 

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
