Unregistered Short Domains

Unregistered short domains are short domain names, currently 3 and 4 characters, in .ai, .io, .md, .sh, .si and .so that are available for registration. The list is updated regularly to reflect the latest availability.

Short names are limited in supply and easier to remember, type, and brand. The Cross-TLD count for each domain shows how popular the same name already is across other extensions, which can indicate market demand.

Type (All, Pure Alpha, Pure Number) is open to everyone. With a free account you can also filter by TLD, Length, TLD Count and Pattern (3 Letter, CVCV, VCVC, CCVV, No Number, No Hyphen), exclude letters you do not want, and change the sort order. CVCV means consonant, vowel, consonant, vowel.

This shows how many other top-level domains (.com, .net, .org, etc.) are already registered for the same prefix. A higher number indicates the keyword is more widely used. Use TLD Availability Search to see exactly which extensions are taken or available for any keyword.

Yes. Click the Register button on any domain to confirm availability and register through registrar partners. Availability may change between the time you view the list and attempt registration, so act promptly on domains you want.
