Helping people with computers... one answer at a time.
Facebook identifies your account through your email address. Deleting one account won't delete the other.
I have two personal Facebook accounts under my name. To make a long story short, while I was on vacation two years ago, I could not access my original Facebook account, so I created a second one using an alternate email address. The problem that I am facing now is that people connect with me through both Facebook accounts while I would rather use just one. I did look into deleting one of them, but I'm afraid that both of my accounts will then be deleted as both are under the same name, but have their own email and password. How do I safely delete just one of my accounts?
In this excerpt from Answercast #16, I look at why and how Facebook tracks accounts through email addresses and how to disable a duplicate account.
Facebook actually doesn't care about your name. What identifies an account completely is the email address.
So, I mean, there aren't many Leo Notenbooms out there, but think of all the John Smiths in the world who perhaps have Facebook accounts?
They are all "John Smith." If Facebook tracked it only by name, then the first John Smith to disable his account would disable all of the John Smiths and that's clearly not gonna happen.
So go ahead and pick the account you want to use. Make sure your friends on the other account know that you're moving and then feel free to delete using the email address as the identifier of the account you no longer you want to use.
The other approach, by the way (since there's nothing really wrong with keeping it open either), is to go ahead and leave it open. But, I'll leave that up to you.
Certainly deleting your Facebook account should be a safe thing since it's identified completely by its email address and you're using different email address for your different accounts.
I do have an article on the subject, "How do I delete my Facebook account?"
