If you are seeing "ID or phone number already exists" when signing-up to an account, it means that you've likely already registered or created an account with us in the past.
You may only have one Coinmama account at a time, so you will need to either:
- Login using your other email address (if possible)
- Update the email address on your existing account
For information on updating your email address please click here. If you get stuck, our Happiness Heroes are only a message away.
