Instagram username format checker
Check basic username length and characters, try simple combinations with a suffix you choose and keep a manual shortlist. This tool checks format; availability stays unknown.
Format check only. Nothing is looked up.
Checked exactly as you type it. No spaces, accents or other characters are removed for you.
Type a name to check its format.
1 to 12 letters, numbers or underscores.
Variations appear once the name passes and the suffix fits. A long name may leave no room for a suffix.
Your shortlist
0 of 20Names you add stay in this tab until you leave.
Opening a profile is a manual check on Instagram. A profile that does not load does not prove the name can be registered.
How to use it
- 1
Type the name exactly as you want it, without the @. Each format rule shows whether it passes, and any unsupported character is named with its code.
- 2
Add a short suffix if you like to see a few variations, and add the ones you like to your shortlist.
- 3
Copy or download the shortlist. Use the links to look at each profile, and confirm your final choice inside Instagram.
Before you export
These basic checks use 1–30 Latin letters, digits, periods or underscores and flag leading, trailing or repeated periods. Passing them is not confirmation that Instagram will accept or assign the name.
No availability requests are made. Reserved names, trademarks and other account restrictions are outside this checker. A profile that does not load is not evidence that its username is available.
