Available One-Word Domains: How Many Are Left by TLD, Language and Length
This article counts the available one-word domains in the Vacant Domains catalog. It covers 72,212 single words in English, German, Spanish and French and shows how many of them are unregistered on each TLD, broken down by language and word length. All figures are from the catalog as of October 26, 2026.
On .com, 1,835 of the 72,212 words (2.5%) can be registered at a standard price. On .io the figure is 32,446 (44.9%), and on .ai it is 28,713 (39.8%). None of the 4,718 words with four letters or fewer is available at standard price on .com.
How the numbers were counted
- Word list. The same list of 72,212 plain words is checked on every TLD: 58,156 English, 4,568 German, 4,996 Spanish and 4,492 French. Each word is tagged with one language. Prefix and suffix variants (such as a word with "go" in front) are excluded.
- Available. A domain counts as available when the most recent registrar API check reported it as unregistered. Checks run through the APIs of Namecheap, Name.com, NameSilo, Dynadot and Spaceship.
- Standard price. A domain is at standard price when the registrar did not flag it as premium. Premium names can be registered, but at a price set above the normal registration fee.
- Recency. For .com, more than 99.9% of these rows were checked in the 30 days before October 26, 2026. Every other TLD in this article had at least 92% checked in that window. TLDs below 90% are left out.
- Excluded rows. The .com data also contains about 69,000 plain words with no language tag. They are excluded so that every TLD is measured against the same list.
The full catalog holds about 8.5 million domains across 51 TLDs, including prefix and suffix variants. About 6.9 million of them were available at the last check.
