Frequently Asked Questions about Phone Number Masking

Phone number masking (also known as call masking) is a privacy solution that is used by businesses to safeguard their customers’ identity and privacy. Call masking works by anonymizing the participating phone numbers by connecting the call through a temporary proxy phone number, and is a solution often used by e-commerce, ride sharing, and food delivery companies. By utilizing Voice APIs and a pool of temporary virtual numbers to connect the customers and the agents, customers and gents can communicate without revealing their personal phone numbers to each other. The number masking feature also allows companies to choose the different, virtual phone number that is displayed on the recipient’s device.
