São Tomé & Príncipe mobile number format
São Tomé & Príncipe mobile numbers are 7 digits long, dialed after the +239 country
code, and typically start with 9. A generated number such as
+239 9555000 has the right shape of a real São Tomé & Príncipe mobile number, but is not
assigned to anyone and cannot receive calls, SMS, or OTP codes.
What you can use them for
- Filling phone fields while testing signup, checkout, or profile forms
- Seed data for a database or a demo environment
- Screenshots, tutorials, and UI mockups that need a realistic number
- Example numbers in documentation
What they are not
These numbers cannot receive SMS or OTP codes. They are not temporary, virtual, or disposable inbox numbers. If you need to actually receive a verification code in São Tomé & Príncipe, you need a real SIM or a paid virtual number service - this is the wrong tool for that.
Is it legal to use a fake phone number?
Yes, for testing, demos, documentation, and mockups. Using any number - fake or real - to impersonate someone, commit fraud, or get around a verification step you're required to complete is not.
