Firebase Phone Number Verification
Fetch verified phone numbers on behalf of users
Get the numbers for devices currently running your app directly from the carrier, using cellular or wifi. No SMS or typing any numbers, just a single button tap does it all.
Reduce fraud and abuse
Eliminate SMS OTPs, phishing, and abuse while reducing fraud. Improve user experience through frictionless sign-ins, which can lead to higher onboarding success rates and increased conversions.
Smooth transition from SMS
Use our SDK to check for carrier compatibility in the background, and know which UI to present. Automatically use new carriers as they become available with no further binary changes.
