Three-letter domains you can still register

How many are left, by extension

Every three-letter name, aaa to zzz. Taken counts registered names, with or without nameservers, and names the registry reserves and does not sell.

“First year from” is the cheaper of Name.com and Namecheap for a normal-price name in that extension today, the same comparison the finder makes; “Renews at” is Name.com’s renewal for these names, and five years is the first year plus four renewals.

Questions

Are there any three-letter .com domains left?

No. All 17,576 three-letter .coms are registered, so one is a purchase from its owner. None sells at the normal price in .net, .org, .co and .ai either.

Where can you still register a three-letter domain at the normal price?

On October 26, 2026, in .fm (14,839), .gg (12,237), .sh (10,726), .company (9,593) and .app (1,894), where we checked every three-letter name, and in 22 more extensions where a random sample found some. Outside .com, 109 three-letter .io names also still sell at the normal price.

What is the cheapest three-letter domain to keep?

Of the extensions where we checked every name, the cheapest to keep over five years are .company ($3.99 the first year, then $24.99 a year: $104 in all), .app ($10.98 the first year, then $26.99 a year: $119 in all) and .sh ($34.98 the first year, then $99 a year: $431 in all). A cheap first year often renews at several times the price, so compare five years, not one.
