Facilitate communication while protecting privacy

Protect user privacy

Avoid revenue leakage

Gain new insights
  • Track, record, and analyze calls to gain new insights on your business.
How it works
Connect your marketplace users without exposing their phone numbers
A user places a call from your app
A user on your service calls a local virtual number to hail a ride, book a place to stay, or to purchase an item from a seller in your marketplace.
The other party picks up
Nexmo’s platform connects the caller with the other party in your marketplace. Neither party sees the other party’s personal phone number; they see only the virtual number your application provisioned for the service.
The conversation takes place
With their personal phone numbers masked, the parties talk and possibly come to an agreement — for a ride, for goods to be purchased through your marketplace, or whatever it may be.
Analyze trends and discover insights
Though the parties can’t see each others’ number, you can. You can generate reports from the console to understand who spoke with whom and when, analyse trends and discover insights that are important to your business. If the call was recorded, it can be transcribed and analyzed for further insights.
