If you're receiving an error message stating that you're phone or email is already in use, it's possible you've already registered for an Uber account.

We recommend that users have only one Uber account for both rides and Uber Uber Eats.

If you need to update the phone number on an existing account, follow the steps listed on the link below.
When you're unable to sign up for a new account because your number is already registered, you'll need to share a few details associated with your account below. This information is requested to ensure the security of your account.
