Your social accounts need a number. It doesn't have to be your personal one.
Social networks ask for a phone number at sign-up, for two-step sign-in and whenever they need to confirm it's really you. A U.S. mobile number in your browser covers all three without putting your personal number on file.
Why the number on your account matters
Your phone number is how a social network recovers your account and confirms a login from somewhere new. If it's a number you could lose, like a SIM from a country you've left, getting back in gets hard. Many platforms also turn away VoIP numbers. A TwinNumber is registered as mobile and stays the same when you move or travel.
Tips
- 01
Use it for two-step sign-in
Codes arrive in your TwinNumber inbox wherever you are, so a trip abroad or a new SIM card never cuts you off from your account.
- 02
Keep work on a work number
Running your company's page or a LinkedIn profile for work? A dedicated number keeps those codes and messages apart from your personal phone.
- 03
Switch numbers in time
Update the phone number on your accounts while your current SIM still receives codes, and only then let the old one go.
Questions
Will the number show on my profile?
That's up to each platform's privacy settings. If anyone does see it, they see your TwinNumber, not your personal number.
Can I get codes while traveling?
Yes. Codes arrive in your browser over any internet connection, with a notification or an email copy if you turn them on.
Can I use one number for all my social accounts?
Yes, for your own accounts. One stable number makes sign-in and recovery simpler on every network you use.
