How to Change Your IMDb ID
Internet Movie Database (IMDb) provides a vast database of film facts, credits, box office finances and much more from practically every movie produced, from studio blockbusters to little-known independent films. If you sign up for an account you are privy to even more information on individuals, films and companies alike, including contact information for studios and agents. If you decide later that you would like to change your IMDb ID, you can do so easily and quickly.

Locate "Change your IMDb ID" under one of the three columns marked "Registration Details" and click the link.
Enter the ID you wish to use in the text box marked "New ID" and click "Change." Congratulations, you have changed your IMDb ID.
