SMS Falcon is an API and web app that provides private virtual phone numbers for receiving SMS verification codes (OTP). Developers and QA teams use it to test sign-up, login and two-factor flows end to end; individuals and small businesses use it to keep a personal number out of sign-ups.
How it works: request a number for an app and a country through the REST API or the dashboard, trigger the verification in the target app, and read the code from the API response or the dashboard. Each number is private to the account that bought it. If no SMS arrives during the number's window, the charge is refunded automatically.
Key facts: 265 supported apps, 156 countries, 90–98% delivery on every service, prices visible before purchase, card and crypto payments worldwide, Pix and crypto for accounts in Brazil, documentation in English, Portuguese and Spanish. Operated by B.F.A LTDA, Brazil.
