Number masking lets two parties talk without seeing each other's real numbers. A temporary number is shown instead.

Number masking means two parties can talk on the phone without seeing each other real numbers. A temporary intermediate number is shown instead, which protects the privacy of both customer and employee. The technique is common in platforms where individuals need to reach each other without handing out their numbers.

How number masking works

  • The system assigns a temporary number that both parties call through.
  • The call connects without revealing the real numbers.
  • The number can expire when the case is done and be reused later.

Examples of when it is used

  • Marketplaces where buyers and sellers should talk safely.
  • Deliveries where driver and recipient need to reach each other.
  • Taxi and sharing services where contact is needed but not private numbers.
  • Customer service calling out without exposing an employee mobile number.
