Masked Phone Numbers

Use case

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 ’ 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

Your customer’s phone number is never revealed during the transaction. After all, the onus of protecting the customer’s privacy falls on the business


In-platform transactions

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


Save cost

Call your customers without depleting your employees’ mobile balance. Connecting them via Exotel is more cost efficient


Track & analyse

Track, record and analyse all your customer conversations to gain insights in real-time

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.
