A Twitter handle is the username that appears after the @ symbol when you post or mention someone on X (formerly Twitter)

Your handle is how other people find and tag you on the platform. When you create an account, you choose a handle during setup — it becomes part of your profile URL and the way people address you in replies and conversations. Unlike your display name, which you can change anytime, your handle is more permanent and is what the system uses to identify you.

A handle can be 4 to 15 characters long and can include letters, numbers, and underscores. You cannot use spaces or most special characters. The @ symbol is not part of the handle itself — it is just how the platform marks usernames when you mention someone or link to their profile.

Key Takeaways

  • Your handle is your username on X, shown with an @ symbol, and is different from your display name.
  • Handles must be 4 to 15 characters and can include letters, numbers, and underscores, but not spaces.
  • You can change your handle in your account settings, though the old handle becomes available for someone else to claim after 30 days.
  • Other people use your handle to mention you in posts, replies, and direct messages.
  • A handle is public and searchable — anyone can find your profile by typing your handle into the search bar.

How handles work in posts and mentions

When someone types @ followed by your handle, X highlights it and turns it into a link to your profile. If they use your handle in a reply to one of your posts, you receive a notification. This is called a mention or tag. You can mention multiple people in a single post by typing @ and their handle for each one.

Handles also appear in direct messages. If you want to send a private message to someone, you search for their handle or display name to find their profile, then open a message thread with them. The handle is the unique identifier that makes sure the message reaches the right person, even if multiple people have similar display names.

The difference between a handle and a display name

Your display name is what appears at the top of your profile and next to your posts — it can be anything you want and you can change it as often as you like. Your handle is the permanent username that other people use to find and mention you. You might have a display name like "Sarah Chen" but a handle like @sarahchen42.

This distinction matters because people often search for you by handle, not display name. If you change your display name frequently, people who know you by your handle can still find you. However, if you change your handle, the old one becomes available for someone else to use after 30 days, and anyone who bookmarked or linked to your old profile URL will find a dead link.

Choosing and changing your handle

When you first create an account, X suggests a handle based on your email or phone number, but you can type in something different. Choose something you are comfortable with, because changing it later can confuse people who know you by the original handle. Many people use their real name, a shortened version, or a combination of their name and numbers.

You can change your handle anytime by going to Settings and Privacy, then Account, then Username. Type in a new handle and X will check whether it is available. If someone else has already claimed it, you will need to choose something different. Once you change it, your old handle is held for 30 days — during that time, no one else can claim it, but after 30 days it becomes available to anyone.

Why handles matter for privacy and safety

Your handle is public information. Anyone can search for it, find your profile, and see whatever you have set to public. This is why many people do not use their full real name in their handle — it keeps their account slightly less discoverable to people who might search for them by name alone.

A handle also makes it easier for people to impersonate you or create accounts that look similar to yours. Someone might create a handle like @sarahchen4 if @sarahchen is taken, hoping to confuse people. X offers verification badges (blue checkmarks) to some accounts to prove they are authentic, but most accounts do not have them. If you are concerned about impersonation, you can report fake accounts to X support.

How to find someone by their handle

If you know someone's handle, you can find them by typing @ and their handle into the search bar at the top of X. The search will show you their profile immediately. You can also search just the handle without the @ symbol and get the same result. Once you find them, you can follow their account, view their posts, or send them a direct message.

If you only know someone's display name and not their handle, searching by display name will show you a list of accounts with that name, and you will have to look through them to find the right person. This is one reason why handles are useful — they are unique to each account, so searching by handle always takes you to exactly one person.

Frequently Asked Questions

Can I have the same handle on X and other social media platforms?

Yes. X does not prevent you from using a handle that exists on other platforms. Many people use the same handle across multiple social media sites to make themselves easier to find. However, if someone else has already claimed that handle on X, you will need to choose something different for your X account.

What happens if I change my handle and someone had bookmarked my old profile?

Their bookmark will stop working. The old handle becomes available for someone else to claim after 30 days, so the URL they saved will eventually point to a different person's profile. This is why changing your handle can be disruptive if people know you by the old one.

Can I use special characters or spaces in my handle?

No. X only allows letters (A–Z, a–z), numbers (0–9), and underscores in handles. You cannot use spaces, hyphens, periods, or other special characters. If you want to separate words, use an underscore — for example, @sarah_chen instead of @sarah chen.

Is my handle the same as my email address?

No. Your email address is what you use to log in to your account and receive notifications from X. Your handle is your public username. You can change your email address in your account settings without changing your handle, and vice versa.

What should I do if someone is using a handle that looks like mine?

If someone has created an account that impersonates you or uses a handle very similar to yours to confuse people, you can report it to X. Go to their profile, tap the three dots menu, and select "Report @[handle]". Choose "It's abusive or harmful" and then "It expresses intentions of self-harm or suicide" or "It's a fake account" depending on what applies. X will review the report.
