Change the cellphone number on your account

Your cellphone number is your Bitcoin4U account, so a new number is registered as an account of its own: confirm a code we text to it and verify your ID again.

Change my phone number

This browser forgets your old number, and we take you to Verify my ID to register your new one.

How it works

Choose "Register my new number". If this browser remembers you, it stops greeting you by name and filling in your old number on our order pages.
On Verify my ID, enter your new cellphone number and the 5-digit code we text to it, then follow the steps to verify your ID.
Once your ID is verified, use your new number every time you buy or sell online or buy at one of our Bitcoin ATMs.

Your old number

Nothing on your old number's account is removed: its transactions stay on our records. Once our verification has matched both accounts to you, a complete statement requested with your new number lists the transactions on your old one as well.

Receipts and the transaction tracker for your old number still ask for a code texted to that number. If you no longer have access to your old number, email us at [email protected] from the address on your account and we will help, with a receipt or an order you placed with it too.

Only changing your email address?

You do not need a new number for that: change the email address on your account instead. Everything else you can do yourself is on My account.
