If you are getting a message that says that a GMC number is linked to more than one account this could be for a number of reasons. It might be that another account was created when assessing a trainee, or that there was an old account from a long time ago that is no longer in use. Or it could simply be that your number was been entered incorrectly.
In all cases the best thing to do is email us and tell us what your correct number should be - it may be that the GMC number on your account is correct, and if so confirming that will help us to locate the issue. We may need you to confirm some further details about previous email addresses so that we can merge accounts.
If your number is incorrect then please tell us what it should be. If it needs to be changed then we will need to update this for you.
