What Is a Username?

A username is the name you use to identify yourself on a website, app, or online service. It is how the system knows who you are, and it is often how other people find and mention you. Depending on the platform, it might be the name you log in with, the handle after an @ symbol, or both. If you have ever signed up for anything online, you have created a username.

These two get mixed up all the time. Your username is usually unique, meaning no one else on the platform can have exactly the same one, and it often cannot contain spaces. Your display name is the friendlier label shown next to your posts, and it can usually repeat, include spaces, and be changed freely. On Instagram, for example, your handle is your unique username, while the name shown in bold on your profile is your display name.

A strong username is short, easy to remember, and easy to say out loud, since people often share handles verbally or type them from memory. It usually connects to you or to what you post, so a new visitor gets an instant sense of who you are. Long strings of numbers and underscores tend to make a name harder to find and to tag, so they are best avoided when you can. When your first choice is taken, adding one short, meaningful word reads better than random digits.

Start with a word that means something to you, like your name, a nickname, a hobby, or your niche. Pair it with a descriptive word if the plain version is taken. Try to claim the same handle across the platforms you use so people can find you everywhere. And test your favorite by reading it aloud before you commit.
