NumberOTP — SMS verification codes

Get a real phone number for any site, and have the SMS code filled in for you.

NumberOTP gives you a real phone number for the site you're on and fills in the SMS verification code when it arrives, without leaving the page. HOW IT WORKS 1. Sign in once. The extension shows a short code; you approve it on numberotp.com. No password is ever typed into the extension. 2. Open the popup on a sign-up page. It suggests a number for that site, or you search any service. 3. Pick a country. You see the price and stock before you buy, paid from your NumberOTP balance. 4. Click "Fill number". The number goes into the page's phone field, with the right country code for the page. 5. When the SMS arrives you get a notification, and "Fill code" puts the code into the page. Allow the site once and the code fills in by itself. No SMS? Cancel the number and the price goes back to your balance automatically. FEATURES • Fill number and Fill code buttons, including split one-digit code boxes • Notifications the moment a code arrives (Web Push, with a polling fallback) • Side panel (Chrome) and sidebar (Firefox) that stays open while you sign up • Your open numbers with a countdown, Copy, Another SMS, Cancel & refund • Top up from the popup (card or crypto on numberotp.com) • 8 languages: English, Spanish, Portuguese, French, German, Russian, Hindi and Arabic PRIVACY AND PERMISSIONS • No access to any website by default. "Fill number" works on the tab you clicked in (activeTab). For automatic code fill the extension asks for that one site, and never for all sites. • It only types into fields. It never reads page content back, never submits forms, and skips password fields. • No content scripts, no remote code, no analytics or tracking. • Sign-in tokens stay in the extension's background; signing out revokes the session. Use it for your own accounts and follow each platform's terms; some platforms don't allow virtual numbers. A NumberOTP account is needed (free to create at numberotp.com).
