Keep Your Personal Number Private at Sign-up
Give a private second number to the forms, apps and services that insist on one — receive the code, and keep your real number off marketing lists and breach dumps. For per-app verification tips, see our app verification numbers.
The Problem
Every sign-up form asks for your phone number, leading to a flood of spam texts.
Sharing your personal number for verification exposes it to data breaches.
OTP codes clutter your personal text messages with codes from dozens of services.
Some services sell your number to third-party marketers after sign-up.
You can't unsubscribe from verification-related spam without losing access to the account.
