The Twitter username (or handle, as some may call it) is probably one of the most important decisions you’ll ever make as a Twitter user. The username defines who you are to the Twitter universe—your personal identity.
The bottom line: It’s very important to pick the right username for your account.
Here are five tips you should take into account when you are setting up your first Twitter account or changing your username.
Keep your username as short as possible.
This one is key: a shorter username is a better username on Twitter. Think about it: your Twitter username will be used in replies, follow fridays, retweets and the like. 140 characters is not an awful lot of space to work with.
Twitter allows usernames to be up to 15 characters, but I recommend keeping your username under 10-12, if at all possible. Don’t underestimate what a difference two to three characters can make.

Try securing a username you already own on other sites for personal branding.
Online identity is becoming more and more important these days, so securing a username on multiple platforms (including Twitter) is likely a very good idea. Think about the usernames you use for your email, your instant messenger clients and your other social networking sites.
Avoid using underscores (_) or excessive numbers.
This is among the most common errors I see with new Twitter users. While using underscores or a few numbers may help you secure a choice username, resist the urge to do so. All too often, people leave out the underscore or a single number, and the user misses a reply.
Instead of using underscores or numbers, test out different variations of a like handle. You may find one you prefer to use instead, and more likely than not, you’ll be better off excluding underscores and numbers from your username.

Before changing my username to @forrestkoba, I branded myself around the sports niche.
Avoid tying yourself to a niche or brand unless the account is for that purpose.
What you originally intend on tweeting about may not be the same thing six or 12 months from your signup date. Make a point to pick a username that is versatile and does not tie you in with a given niche or brand, unless you are directly affiliated with the brand or intend on using your Twitter account solely for a single niche.
This was one of my pitfalls when I signed up for the service. Since I planned on tweeting mostly about sports, I picked the username @forrestfanatic. However, the more I used Twitter, the more I found myself tweeting about other interests (tech, design, news). I just recently changed my username to a shortened version of my name, shedding the sports-only niche.
Pick a username that you think you’d be happy with one year from now.
Who isn’t in Twitter for the long term? Think about this: one year from now, will you be happy with the username you’ve selected? Ultimately, it is up to the user as to what makes him/her most happy with a username, so whatever you pick, make sure it’s something you like and something you want to stick with for a while.
