What is Twitter's character limit for usernames?

As of my last update, the character limit for Twitter usernames, also known as Twitter handles or @mentions, is 15 characters. This includes letters, numbers, and underscores. Usernames can also contain periods, but a period cannot be the first character in the username.

For example, the username "@example_user123" is within the character limit, while "@.exampleuser" exceeds the limit because the period is the first character.

It's important to choose a username that is memorable, easy to spell, and reflects your identity or brand on Twitter. Keep in mind that once you've chosen a username, it cannot be changed, so choose wisely!
