How to Find a Facebook Profile ID (2026): Desktop, Android, iPhone

Last checked: October 2026.

A Facebook profile ID is the long number Facebook gives every account. You don't see it day to day, but you'll get asked for it when you set up an app, fill in a support form, add someone to a tool that manages your social accounts, or report a problem with a profile that keeps changing its name.

Facebook's own Help Centre explains that every account has a user ID, whether or not it has a username. The username is the friendly part of your profile address, and you can change it. The ID is a string of numbers that stays with the account. Below I'll walk you through finding it on a computer, on Android and on iPhone, plus how group IDs work and why you rarely need an outside ID finder.

What is a Facebook profile ID and why would you need it?

Think of the profile ID as the account's permanent reference number. Facebook's Help Centre says it connects to your profile and to specific Messenger chats, and that apps connected to your account can use it to see your public information. Developers can also use it to look into problems you report with an app or game.

For a small business owner, the common reasons are practical ones:

• Setting up a scheduling or customer service tool that asks for an ID rather than a link.
• Giving a developer or virtual assistant the right account to add as an admin or tester.
• Reporting a fake or copycat profile, where the name can change but the number can't.
• Keeping a clean record of an account in your own files, in case the username changes later.

How do you find a Facebook user ID on a computer?

The quickest check is the address bar. It works straight away for any profile that hasn't set a custom username.

1. Open Facebook in your browser and go to the profile you want, yours or someone else's.
2. Look at the web address at the top of the browser.
3. If it reads facebook.com/profile.php?id= followed by a number, that number is the profile ID.
4. Copy only the digits after id= and paste them wherever you need them.

If the address shows a name instead, such as facebook.com/yourname, the profile has a username and the ID isn't shown there. You can still find it. Right-click an empty part of the page, choose the option to view the page source, then use your browser's find tool to search for profile_id or userID. The number that follows is usually the ID. Facebook changes its page code often, so if one search term finds nothing, try the other.

How do you find your Facebook profile ID on Android or iPhone?

The Facebook app doesn't show the ID as a labelled field, so you'll use the profile link instead. Menu names can vary a little between app versions, but the route looks like this:

1. Open the Facebook app and go to the profile.
2. Tap the three dots next to the buttons under the name.
3. Scroll down to the profile link section and tap Copy link (on some versions it's called Copy link to profile).
4. Paste the link into your notes app or a message to yourself so you can read it.
5. If you see id= followed by digits, those digits are the profile ID.

If the copied link shows a username or a short share link instead of id=, open the same profile on a computer and use the page source method above. It's the most reliable way to read the number for a profile with a username.

Facebook ID types at a glance

People mix these up all the time, so here's how they compare:

ID type	Where to find it	What it's used for
Profile (user) ID	Address bar on profiles without a username, the copied profile link, or the page source	Apps, support forms, admin access, reporting fake accounts
Username	The name after facebook.com/ in the profile address	A friendly link you can share and change
Group ID	The group address, or Share then Copy link inside the group	Tools that post to or manage groups
Page ID	The business Page itself, not a personal profile	Ads, business tools and Page settings

How do you find a Facebook group ID?

1. Open the group in your browser or app.
2. Look at the address. If it reads facebook.com/groups/ followed by a number, that number is the group ID.
3. If the group has a custom name in its address, tap Share inside the group and then Copy link, or use the page source search on a computer and look for group_id.
4. Paste the result somewhere you can read it before you copy the digits into the tool that needs them.

One quick pointer: a Page ID is different again. Business Pages have their own IDs, and you'll find them from the Page itself, not from your personal profile. If a form asks for a Page ID, don't give it your profile ID.

Are Facebook ID finder sites safe to use?

You'll see plenty of sites that promise to find any Facebook ID if you paste in a profile link. Some may work, but it's worth thinking twice:

• You're handing a stranger's website a link to a profile, and you don't know what they log or keep.
• Some ask you to connect your Facebook account or click Allow. That gives an outside app access you may not want to grant.
• Pages full of pop-ups and download buttons are a warning sign. Close them.
• You rarely need one. The address bar, the copied profile link and the page source cover almost every case.

What can someone do with your Facebook ID?

On its own, not much. Facebook's Help Centre says the user ID doesn't personally identify you, but it does connect to your profile, and someone who has it can view whatever you've made public. That's the same information they'd see by visiting your profile, so the real protection is in your privacy settings, not in hiding the number.

It's still sensible not to post your ID publicly next to your email address or phone number. Scammers like to stitch small bits of information together. For anything else you're trying to sort out on the platform, my Facebook help guide collects the most common fixes in one place, and if you're tidying up old content, here's how to find archived Facebook posts.

Quick checks before you share a Facebook ID

• Make sure you've copied the digits only, with no letters, slashes or question marks.
• Check it's the right type of ID: profile, group or Page.
• Open facebook.com/profile.php?id= followed by the number in your browser to confirm it lands on the right profile.
• Only share it with tools and people you trust, and remove app access you no longer use.

Frequently asked questions

How do I find my Facebook ID number?

Open your profile in a browser. If the address shows profile.php?id= followed by a number, that's your ID. If it shows a username, copy your profile link from the app or search the page source for profile_id or userID.

Is my Facebook username the same as my profile ID?

No. Your username is the changeable name in your profile address. Your profile ID is a fixed number that Facebook gives every account, whether or not it has a username.

Can I find someone else's Facebook ID?

Yes, for profiles you can see. The same methods work: check the address bar, copy the profile link, or search the page source. You'll only see what their privacy settings allow.

Can my Facebook profile ID change?

The ID stays with the account. Your username and display name can change, which is why tools and support teams often ask for the number instead.

Do I need a Facebook ID finder website?

Usually not. The address bar, the copied profile link and the page source cover most cases, and they don't ask you to paste links into an unknown site or connect your account.
