How it works

Three ways to verify, tried in order.

Verified picks the fastest channel each phone supports and falls back automatically. The check takes about half a second.

1

The number fills itself in

On supported carriers, Verified reads the verified number from the phone’s SIM. The user just taps to confirm.

2

No code to type

The user enters their number and Verified confirms it with the carrier in the background. Works on all three major US carriers.

3

A code or link, as a backup

If neither is available, Verified texts a code, a link or both. Works on every carrier, over Wi-Fi or cellular.

The problem

Phone verification is where signups leak.

Text codes are the standard way to verify a phone. They’re slow, clunky and easy to abandon.

Verified customersPhone verification
3–25%

of users drop off at the phone verification step, depending on the company.

Waiting for the text

Codes can take seconds or minutes to arrive, and some never do.

Leaving your app

People switch to their messages to find the code, and some don’t come back.

Typing six digits

Every code is another chance for a typo, a timeout or a resend.

Integration

Integrate in about 15 minutes.

Use our SDK for the full flow, build your own screens on the API, or drop our native module into your app. Test everything in Sandbox first.

FAQ

Questions about 1-Click Verify

Which carriers support autofill?

Verizon and T-Mobile, plus most of the networks that run on them. ATVerizon and T-Mobile support autofill, where the user doesn’t have to enter anything. Verizon, T-Mobile and AT&T support silent, where the user has to enter their phone number, but they don’t have to receive an SMS or enter a verification code.T doesn’t support autofill, so AT&T users verify silently instead.

Does it work on Wi-Fi?

Autofill and silent verification need a cellular connection. Native apps can use cellular even when the phone is on Wi-Fi. Web apps use whatever connection the user has, so texts are more common on the web.

What happens if a channel isn’t available?

Verified moves to the next one automatically: autofill, then silent, then a text that works on every carrier.

Can we use 1-Click Verify on its own?

Yes. Use it anywhere you need a verified phone number. It’s also the first step of 1-Click Signup, which can flow into 1-Click Health.

How long does it take to go live?

Less than an hour. Before launch, our compliance team and the carriers review your consent language, which takes 3 to 5 days.

Can we customize the texts?

Yes. Choose a code, a link, or both. Every message includes your brand name, and links can send people wherever you choose.

Is 1-Click Verify available outside the US?

Not yet. It works with US mobile numbers today.
