We are sorry, but we do not recognize you as an authorized UnitedHealthcare provider - here are some reasons that might be:

Do you need to connect your TIN to your Optum ID? Or add another?

Use the "Connect TIN" button below to enter your Optum ID and click "No" when asked if you received a registration letter that included a security code. From that point, complete the required fields for the form as prompted.

Did you connect your TIN to your Optum ID recently?

We may need more time to process your request before recognizing you. For help, please contact your Practice Administrator or Network Management Contact.

Do you not have an Optum ID? Register for one today.
