Display names, handles and what you can change on X

Every X profile has two names. The display name is the bold one at the top of your profile and next to every post. The username, also called the handle, is the @name that people type to mention you and that appears in your profile's web address. They follow different rules and do different jobs, and people often confuse them when they set up or rename an account.

The display name

The display name is how you introduce yourself. X allows up to 50 characters, and it doesn't have to be unique, so a thousand people can be called Sam Rivera. It accepts spaces, punctuation and emoji.

Because it appears next to every post and reply, the display name gets read more often than anything else on your profile. That has two practical effects.

The first is truncation. On a phone, a long display name is cut off in replies and timelines, often after about 20 characters depending on the screen and the length of the handle beside it. Whatever you put first is what most people see. "Sam Rivera | ICU Nurse | Runner | Dog Mom 🐶" will usually show as something like "Sam Rivera | ICU Nur…".

The second is search. People search X by name, so if you want old friends or colleagues to find you, your real name, or the name they know you by, should be in there.

Popular patterns for display names:

• Just your name. Clean, and the most common choice.
• Your name plus a short role: "Sam Rivera, RN".
• Your name plus pronouns in parentheses: "Sam Rivera (she/her)".
• A brand or creator name, if that is what people know you as.

What tends not to work: long chains of labels, several emoji before your name, and all caps. Each of those pushes your actual name out of view in the places people see it most.

The username, or handle

The username is your address on X. It shows as @samrivera on your profile and in mentions, and it forms the end of your profile URL. X's rules for it are stricter:

• Up to 15 characters.
• Letters A to Z, numbers 0 to 9 and underscores only. No spaces, dots, dashes or other symbols.
• It must be unique. If someone else has it, you can't.
• Words like "X" and "Admin" are reserved for official accounts, so handles built around them may be refused.

Usernames are not case-sensitive for mentions, so @SamRivera and @samrivera reach the same account. Capitals are still worth using for readability, as in @SamRiveraRN.

A good handle is short, easy to say out loud and easy to spell. If your name is taken, try adding a role or a place (@SamRiveraRN, @SamInDenver) before adding a string of numbers. Numbers are hard to remember and can make an account look automated. Underscores are allowed, but a handle with two or three of them is easy to mistype when someone tries to tag you.

Changing your display name

You can change your display name in Edit profile at any time. Your followers, posts and handle all stay the same, so the risk is low. People may just need a moment to recognize you in their timeline.

There is one thing to check. If your account has a verified checkmark through a paid subscription, changing your display name, profile photo or username can make the checkmark disappear for a while until X reviews the account again. If the checkmark matters to you, make all your profile changes in one go rather than over several days.

Changing your username

Changing the handle is a bigger decision. You change it in your account settings, under your account information, and X checks whether the new one is available as you type. When you change it:

• Your followers, posts and direct messages stay with you.
• Old posts that mention your previous @name keep showing the old text, and those mentions no longer link to you.
• Links to your old profile URL stop pointing to your account.
• Your old username becomes available for someone else to claim, though usually not instantly.

Because of the last two points, a handle change can be confusing for people who knew you by the old one, and in a worst case someone could pick up your old @name and receive mentions meant for you. If you are changing it, post about it from the account first, update the link in your other profiles and email signature, and consider keeping the old handle on a second account that points to the new one.

Name and handle together

The two names work best when they match. If your display name is "Sam Rivera" and your handle is @sriv_88, people have to work harder to connect them, and it's harder to find you by searching. Ideally your handle is your name, or your name plus a short role or place.

Creators and small brands face a choice: should the display name be the person or the project? Use whichever people will search for. A podcaster known by the show name might use "The Night Shift Podcast" as the display name and put "Hosted by Sam Rivera" in the bio. Someone building a personal following should usually lead with their own name.

What else you can change

Besides the names, your profile has a bio of up to 160 characters, a location of up to 30, a website field, a profile photo, a header image and a pinned post. All of them can be changed in Edit profile, and none of them affects your followers. We cover the bio in how to write an X bio that works and the pinned post in the pinned post and bio guide.

X changes its settings from time to time. The limits in this guide were checked against X's Help Center in November 2026. Our writer checks your display name and username against them as you type.
