NUMBER MASKING

Increase privacy and security for businesses and customers alike by using number masking to anonymize voice calls. Add number masking to safeguard identity and heighten the user experience whilst also protecting your business, ensuring that all communications remain on platform, avoiding revenue leakage and increasing user retention.

PRODUCT USE CASES

Let drivers and passengers call each other with Number Masking, without ever sharing a personal phone number

Users can connect to each other to share important and timely information about upcoming deliveries and other services

Marketplaces

How it works

By renting a virtual local number, your customers will use this as a bridge for their communication. It’s all very simple: you let us know which number we should forward the incoming call or SMS to and we simply switch the CLI/senderId so the receiver only sees your virtual local number. Check out our tutorial on how to add anonymous calling to your app
