Check availability and claim it before someone else does

Instagram usernames are first-come, first-served. Once someone takes a username, you cannot get it unless they delete their account or change their username themselves. The only way to find a unique username is to claim it while it is still available.

Go to Instagram.com or open the Instagram app. If you are not logged in, sign in to the account where you want the username. Tap your profile icon at the bottom right, then tap "Edit profile." Next to your current username, tap the username field. Instagram will show you whether your desired username is available — a green checkmark means you can use it, a red X means someone already has it.

If the username is available, type it in and tap "Done" or the checkmark. The change takes effect when ready. If it is taken, you will need to try a different variation.

Key Takeaways

  • Instagram usernames are claimed on a first-come, first-served basis, and you cannot reserve one before you are ready to use it.
  • You can change your username once every 14 days, so test variations before settling on one you want to keep.
  • Adding numbers, underscores, or periods to a name makes it unique when the plain version is taken — for example, sarah.jones or sarahjones22.
  • Usernames can be 1 to 30 characters long and can include letters, numbers, periods, and underscores, but cannot start with a number.
  • If you change your mind, you can switch to a different username, but the old one becomes available for anyone else to claim when ready.

What characters and lengths Instagram allows

Instagram usernames can be between 1 and 30 characters long. You can use letters (a–z, A–Z), numbers (0–9), periods (.), and underscores (_). You cannot use spaces, hyphens, or special characters like @, #, or &. Usernames are case-insensitive, so Sarah.Jones and sarah.jones are treated as the same username.

One rule: your username cannot start with a number. It can contain numbers anywhere else, but the first character must be a letter or underscore. This is why usernames like 22sarah are not allowed, but sarah22 or _sarah are.

How to make a taken username unique to you

If your first choice is taken, you have several ways to modify it. Adding a number at the end is the most common approach — sarah becomes sarah22 or sarah2024. Adding an underscore before or after a word works too: _sarah or sarah_. A period between words creates a professional look: sarah.jones or sarah.design.

Combining these methods gives you more options. If sarah_jones is taken, try sarah.jones, sarahjones22, or _sarah_jones. The key is to keep it short enough to remember and type easily, while still being distinct from the original.

Some people add their location, profession, or interest to make it unique: sarah_photography, sarahfromboston, or sarahdesigns. This also helps people understand what your account is about at a glance.

The 14-day waiting period between changes

Once you change your username, Instagram requires you to wait 14 days before changing it again. This means you should test a few variations in your head before you commit. Write down your top three choices and sleep on them — you do not want to change it twice in a week and then be stuck with a username you do not like.

The 14-day timer starts the moment you save the change, not when you think about making it. If you change from sarah to sarah22 on Monday, you cannot change to sarah_jones until the following Monday.

What happens to your old username when you change it

When you switch to a new username, your old one becomes available for anyone else to claim when ready. You cannot reserve it or hold it. If you think you might want to go back to it later, you should know that someone else might take it first.

Your profile, followers, posts, and messages all stay with your account — only the username changes. People who follow you will still see your account, but the old username will no longer lead to your profile.

Why Instagram does not let you reserve usernames

Instagram treats usernames as active identifiers, not property you can hold. The platform assumes that if you are not using a username, someone else should have the chance to. This is why you cannot claim a username and then decide to use it later — you have to be ready to use it now.

This system prevents people from hoarding popular usernames or sitting on them for resale. It also means that if an account has been inactive for years, someone else can eventually claim that username if the original owner changes it or deletes their account.

Frequently Asked Questions

Can I get a username that someone else is using?

No. The only way to get a username someone else has is if they delete their account or change their username themselves. Instagram does not have a process to request or claim a username from another active user.

What if I want to change my username back to what I had before?

If someone else has claimed your old username, you cannot get it back. You will have to choose a different one. This is why it is worth thinking through your username choice before you change it.

Can I use spaces or hyphens in my username?

No. Instagram only allows letters, numbers, periods, and underscores. Spaces and hyphens will not work. If you want to separate words, use an underscore (sarah_jones) or a period (sarah.jones).

Do I have to wait 14 days if I made a typo?

Yes. Even if you change your username by mistake, the 14-day waiting period applies. You cannot change it back right away. Plan your username carefully before you save it.

Will changing my username affect my followers or posts?

No. Your followers, posts, messages, and all other account data stay exactly the same. Only the username changes. People who follow you will still see your account under the new username.
