# Free username checker and ideas for Instagram

Check a handle for length and allowed characters, and get username ideas built from your words with fixed templates. Free, in your browser.

Enter a username to check it against common handle rules: up to 30 characters, with only letters, numbers, periods and underscores. Enter your own words to get username ideas from fixed templates. The check runs in your browser and tells you which rule a name breaks, so you can fix it before you try to claim the handle.

## How it works

The checker flags what would break the usual rules and adds advice for names that are legal but awkward, such as two periods in a row.

Ideas combine your words with short prefixes, suffixes and separators. Every idea passes the same check, and the same words always give the same list.

> It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, [start a trial](https://get1post.com/signup.md) and open it in the composer.

## Questions

**What does it check?**

The shape of the name: length, allowed characters and awkward patterns such as two periods in a row. It also suggests alternatives to try.

**Why are ideas the same each time?**

They come from fixed templates and your words, so the same input gives the same list. Change a word to change the list.
