4-letter domain list

Every unregistered four-character .com in our index, A to Z. Pure letter names are almost all taken, so the list is made of letter and digit names you can register at the regular price. Browse it here for free, or download it as a text file: samples are free, and the full file comes with Pro.

What's in the list

One name per line, each one confirmed unregistered by our last check against the Verisign registry. Reserved names that the registry blocks are removed before a name is published.

Working with the list

A plain text file works with grep, spreadsheets or your own scripts. Filter for patterns you like, such as names ending in a digit or names with a double vowel, then check the ones you want on their domain pages before you register.

Keeping it current

Names get registered every day, so an old copy goes stale. The list is refreshed after the daily scan, and the available list on the home page always shows the latest data.

Frequently asked questions

Is there a free list of available 4-letter domains?
You can browse and filter the full list free on the home page. The download page has free sample files, and Pro members can download the complete list as .txt or .txt.gz.
Why are there no letter-only names on the list?
Pure letter .com names are almost always registered. When one drops and is still unregistered at our next check, it appears here and on the available 4-letter domains page.
