How to Change Your Facebook Username in the App ?

How to change your Facebook username in the Facebook app — updated 2026 guide.

Your Facebook username is more than a small setting buried in your profile — it is the handle that appears in your profile link (facebook.com/yourusername), the name people can tag you with in Messenger, and part of how your profile shows up in search results. Whether you picked a random username years ago, changed your legal name, are rebranding a business page, or simply want a cleaner and more professional handle, this guide walks you through exactly how to change your Facebook username in the Facebook app, on both Android and iPhone, using the current 2026 menu layout.

We also cover the rules Facebook enforces around username changes, the most common errors people run into, the difference between your name and your username (a mix-up that trips up almost everyone), and what happens to your old link once you switch. Everything below reflects Facebook's current Accounts Center-based settings menu.

What Is a Facebook Username, Exactly?

A Facebook username (Facebook also calls this your "vanity URL") is the unique string of text that appears at the end of your profile link, right after facebook.com/. For example, if your username is "john.doe", your profile link is facebook.com/john.doe. This is different from your account's numeric Facebook ID, and different again from your display name, which is the name shown at the top of your profile and next to your posts.

Your username is used in a few important places:

• Your personal profile link, which you share with friends, on business cards, or on other social platforms
• Messenger, since Facebook and Messenger share the same username system
• Search results, where a clean username can look more polished and trustworthy
• Instagram, if you have profile syncing turned on between the two apps

Facebook Username vs. Facebook Name: The Key Difference

This is where a lot of people get stuck. Facebook has two separate identity settings that live in two separate menus:

• Name — the display name shown on your profile, in your posts, and in search. Facebook expects this to be the name people know you by in real life, and changing it can trigger a review or an ID check for unusual edits.
• Username — the custom handle that forms your profile link (facebook.com/yourusername). It follows different formatting rules and is changed through a separate "Username" screen inside Accounts Center.

If you only change your display name, your profile link and username stay exactly the same. You have to update them separately if you want both to match.

Before You Start: Things to Check First

A few minutes of prep can save you from a frustrating retry loop:

• Update your app first. If your Facebook app is more than a year or so old, your settings menu may look different from the screens described here. Update from the App Store or Google Play before making the change.
• Decide on 2–3 username options. Popular words and short handles are often already taken, so have backups ready.
• Know that you may not get your old username back. Facebook's Help Center notes that once you change your username, you may not be able to reclaim the previous one, so don't change it on a whim if your current link is already shared widely.
• Note any links pointing to your old profile URL. Business cards, email signatures, other social bios, and website links that reference your old facebook.com/oldusername address will need to be updated after the switch, since old links won't automatically forward for personal profiles.

How to Change Your Facebook Username in the App (Step by Step)

The core steps are identical whether you're on an Android phone or an iPhone, since Facebook now routes username changes through the shared Accounts Center panel. Here's the full walkthrough:

1. Open the Facebook app and make sure you're logged into the account you want to update.
2. Tap your profile picture in the top right corner of the screen (on some Android layouts, tap the three-line menu icon instead).
3. Scroll down and tap "Settings & privacy."
4. Tap "Settings" from the drop-down menu that appears.
5. Tap "Accounts Center" — this is the panel Meta uses to manage settings shared across Facebook, Instagram, and Messenger.
6. Tap "Profiles" and select the specific Facebook profile you want to change the username for (useful if you manage more than one profile or page).
7. Tap "Username."
8. Clear the existing text and type your new username. Facebook checks availability in real time and will let you know instantly if the name is taken or invalid.
9. Confirm your password if prompted, then tap "Save" or "Done" to lock in the change.

That's it — your profile link updates immediately, and the new username is active across Facebook and Messenger right away.

Changing Your Username on iPhone (iOS)

On iPhone, the profile icon sits in the bottom-right corner of the Facebook app rather than the top right. Aside from that, the path is the same: Profile icon → Settings & privacy → Settings → Accounts Center → Profiles → select your profile → Username → enter your new handle → Save.

If you don't see "Accounts Center," scroll further down the Settings screen — Meta has been rolling this panel out gradually, and it sometimes sits under a "Personal details" or "Meta Accounts Center" heading depending on your app version and region.

Changing Your Username on Android

On most Android phones, tap the hamburger menu icon (three horizontal lines) in the top right instead of a profile photo. From there the steps match: Menu → Settings & privacy → Settings → Accounts Center → Profiles → your profile → Username → type new username → Save.

Some Android skins and older app builds still show a direct "Username" row under Settings without routing through Accounts Center — if that's what you see, tap it directly, enter your new username, and confirm with your password.

How to Change a Facebook Page's Username

If you manage a business or brand Page rather than a personal profile, the steps are slightly different since Pages have their own admin tools:

1. Open the Facebook app and go to your Page.
2. Tap "Edit Page Info" (or "Manage Page" → "Page info," depending on your app version).
3. Tap the Username or "@" field.
4. Enter your new Page username and tap "Save" or "Check Availability" first, then "Save."

Page usernames must generally be at least five characters long, and admins are typically limited to changing a Page's username roughly once every 60 days, so pick carefully before saving.

Facebook's Username Rules and Character Limits

Facebook enforces a specific set of formatting rules for personal profile usernames:

• Only letters (A–Z), numbers (0–9), and periods (.) are allowed
• Periods and capitalization are cosmetic — "John.Doe" and "johndoe" are treated as the same username
• No spaces, symbols, or special characters
• Usernames generally need to be at least five characters
• You cannot use another person's name, a trademarked term, or anything that violates Facebook's Community Standards
• Extremely generic single words are usually already taken, since Facebook has billions of active accounts

Meta has also indicated that non-Latin (non-romanized) character support for usernames may be introduced in the future, though as of now, standard usernames are limited to the Latin alphabet, numbers, and periods.

Common Errors and How to Fix Them

"This username isn't available"

Someone else already has that exact username (remember, periods and capital letters don't count as different). Try a variation — add a middle initial, a number, or a period in a different spot.

"This username isn't allowed"

Your chosen username likely contains a restricted word, resembles a trademark, or violates Facebook's naming policies. Try a version that's clearly personal and unrelated to brand names or public figures.

The Username field won't load or the Save button is greyed out

This is often a temporary app glitch. Force-close the Facebook app, make sure you're on the latest version from the App Store or Google Play, and try again. If the problem persists, try the same steps on the Facebook mobile website through a browser.

You just changed your username and want to change it again

Facebook may temporarily restrict back-to-back changes. If you're blocked from changing it again right away, wait a short period and retry — this cooldown exists specifically to prevent username squatting and abuse.

What Happens After You Change Your Username

• Your profile link updates instantly to facebook.com/yournewusername.
• Your Messenger username updates automatically, since Messenger shares the same identity system as Facebook.
• Your Instagram username only changes if you've enabled Sync Settings between Facebook and Instagram inside Accounts Center. If sync is off, Instagram keeps its own separate username.
• Your old profile link may no longer work for visitors, and Facebook notes you may not be able to reclaim that old username later — so update any external links (LinkedIn, email signature, website, other bios) that pointed to the old URL.
• Friends can still find you by name in Facebook search even after the change, since search isn't solely dependent on your username.

Tips for Choosing a Strong New Username

• Keep it consistent with your other platforms. Matching handles across Instagram, TikTok, and X (Twitter) makes you easier to find and looks more professional.
• Avoid numbers and random characters unless necessary — cleaner usernames are easier to remember and share verbally.
• For business Pages, use your brand name exactly as it appears elsewhere, to avoid brand confusion.
• Double-check spelling before saving. Since you may not get an old username back and future changes can be restricted, a rushed typo can be inconvenient to fix.
• Test the link after saving by opening facebook.com/yournewusername in a browser to confirm it loads your profile correctly.

Frequently Asked Questions

How many times can I change my Facebook username?

Facebook's official Help Center advises being careful before changing your username, since you may not be able to reclaim your original one afterward. Facebook Page usernames can typically be changed by an admin roughly once every 60 days.

Will changing my Facebook username change my profile URL?

Yes. Since your username is the part of your link that appears after facebook.com/, updating it automatically updates your profile URL.

Does changing my Facebook username also change my Messenger and Instagram username?

Your username is shared with Messenger automatically. It only updates on Instagram if you have profile syncing turned on in your Accounts Center sync settings.

Why does Facebook say my new username isn't available?

This typically means the exact username is already taken by another account, it doesn't meet Facebook's length or character requirements, or it's flagged for resembling a trademark or public figure's name. Try a close variation and check availability again.

Is changing my Facebook username the same as changing my name?

No. Your display name is what appears on your posts and profile, while your username is your unique link handle. They're edited in separate settings screens and follow different rules — name changes can trigger identity review, while username changes are checked for availability and formatting.

Final Thoughts

Changing your Facebook username in the app takes only a couple of minutes once you know where the setting lives: Settings & privacy → Settings → Accounts Center → Profiles → Username. The trickier part is picking a username that's available, matches your branding, and follows Facebook's formatting rules on the first try — since you may not be able to switch back to your old one afterward. Take an extra minute to double-check your spelling, update any external links pointing to your old profile URL, and you'll be set with a cleaner, more shareable Facebook handle.
