Before we get to the instructions, it's important to understand the difference between these - an explanation of the difference can be found here.
If you've created two accounts (i.e. registered twice on IMDb with two different emails), see this help article about how to handle.
IMPORTANT: A name page can only be considered 'empty' if it does not contain any bio, credits, performer profile, photos or Contact data - some of which you cannot see or access unless you are an IMDbPro member. If you don't have an IMDbPro membership, check for a More at IMDb Pro section - if a name page has links to Contact Info or Clients etc, the page isn't empty and you shouldn't merge it.
Name Merges can be used to combine entries for a single person that appear under two or more different names. In this case, you should decide which name should remain -- usually the name used most often, though if a person is expected to use a single name for all future credits, this would be the one to choose. If you're confident two pages should be merged together, take a look at the written instructions below.Step by step instructions
Please note that the updates may happen in stages, which can mean that some credits may disappear for a day or two while the merge is being processed.
