## Strictly limited supply

There are 17,576 possible three-letter combinations and 1,000 three-digit numbers. Unlike longer names, no new ones can be created, and almost all of them were registered years ago. Short .ai names change hands on the aftermarket instead.

## Who uses short .ai domains

- Companies and funds known by their initials.
- Apps and products that need a name that fits a small screen.
- International brands, especially numeric names that read the same in every language.
- Marketing campaigns and redirects that must be easy to type.

## Letters, numbers and pronounceable names

Three-letter names with common letters and an easy rhythm are usually valued highest. Numeric names are popular in Asian markets, where certain digits carry meaning. Four-letter names that can be pronounced as a word work well as compact brands.
