Go to facebook.com/login/identify on a phone or computer you've logged in from before, then try every email address and mobile number you've ever owned, one at a time, followed by your username and variations of your name. Facebook also says a friend can look up the contact details on your profile or send you your profile web address, which contains your username, so as of Nov 2026 the job is feeding the search every detail your account might be filed under.
The identify page is a search box, nothing more. It can only match what you type against what's stored on the account. When it says it can't find you, the account may well still be there; the search just hasn't been given the detail it's filed under. Everything below is what Facebook's own Help Centre says to type, and where.
Run the search somewhere familiar
Facebook's advice is to search from a familiar device. It gives examples: your own phone or computer, an old phone, or a family member's laptop. Type facebook.com/login/identify into the browser you usually use there, rather than a new browser you've just installed.
That's worth a minute of thought before you start. If you used to check Facebook on an old work laptop or a tablet the kids now play games on, that might be the device Facebook knows best. Dig it out, charge it and start there.
Everything the search box will accept
Most people type the email they use today, get no match and give up. Facebook's troubleshooting tips are wider than that:
| What you could type | What Facebook says |
|---|---|
| Old email addresses | Try each one you've owned, one at a time; you may have added an old address and forgotten about it |
| Old mobile numbers | Same advice: each number you've owned, one at a time, as an old one may still be on the account |
| Your username | Enter it if you created one; it's your personalised Facebook web address |
| A nickname or a variation of your name | Try variations in case you signed up with a nickname |
| A friend's full name, if asked | Try several friends if the first doesn't locate an account, and use full names, not just first names |
| An email that sign-up says is taken | You can't create a new account with an email already tied to an existing one, which tells you an account is on it |
Think about the business side of your history here. The email from a job you left, the address on a domain you let lapse, the number from a phone contract you cancelled years ago. Any of those could be the one Facebook has on file.
The search, in order
- Pick up a phone or computer you've logged in from before.
- Go to facebook.com/login/identify in your usual browser.
- Enter each email address and mobile number you've ever owned, one at a time.
- If none of those match, try your username, then variations of your name.
- If you're still stuck, ask a friend to send you your profile web address or the contact details shown on your profile.
Keep a list as you go, so you aren't typing the same address twice and missing the one you haven't tried.
Getting the mobile number format right
Phone numbers are where a lot of searches quietly fail. Facebook's article on logging in with a phone number says to enter your entire mobile number, including the country code, and to leave out any extra zeros, plus signs or other special characters.
So a number you'd normally write with a leading zero won't match as typed. Drop the zero, add the country code and skip the plus sign. The Log in to Facebook article backs that up: no zeros before the country code and no symbols. If the number still fails, the same article sends you back to facebook.com/login/identify on a device you've used before.
What a friend can see that you can't
Locked out, you can't look at your own profile. A Facebook friend can, and Facebook suggests two ways they can help. They can open the About section of your profile and send you the email address or mobile number listed under Contact information. Or they can go to your profile and send you the username in its web address.
That second one is often the quickest win. If you set a username years ago and forgot it, it's sitting in plain sight in your profile link. Finding a Facebook profile ID or URL shows what to look for if your friend isn't sure where to find it.
If they're trying to find someone else entirely, not your account, that's a different job, and how to find someone on Facebook is the page for it.

When sign-up says the email's already taken
Plenty of people try to make a fresh account and get told the email is already in use. That's a clue, not a dead end. Facebook says you can't create a new account with an email address already tied to an existing one, so an account is sitting on that address.
Facebook adds two things. If you share an email address with someone who has an account on it, it suggests creating a free email address of your own. And it's against Facebook's Community Standards to keep more than one personal account; if you sign up with the same or a similar email and password as an account you've already made, Facebook says you'll be logged in to that existing account. So the second sign-up can lead you straight back to the first.
Once your account turns up
Facebook's article for people who aren't sure they still have an account says that once it's found, you can reset your password to keep using it, or delete it. If you find it but still can't get in, Facebook has separate recovery steps for that. If you think someone's taken it over, Facebook says to visit www.facebook.com/hacked on a device you've logged in from before.
If the account doesn't turn up because you deleted it, that's its own question, and getting a deleted Facebook account back covers it. For general login trouble, fixes for when you can't log into Facebook is the wider list.
Where I'd look first
I'd start with the oldest email address you can remember, on the oldest device you can still switch on. Facebook says an old address you forgot adding may be the one on the account. Then I'd text a friend for your profile link before trying a dozen name spellings. Skip making a new account to get around it; Facebook's one-account rule means you'll likely end up back at the old one anyway.
