5-Letter .io Domains That Are Still Available

5 letters is 11,881,376 possible .io names. The zone file lists 104,133 of them as registered, so about 11,777,243 are not — an estimate rather than a bound, since a zone misses a registration nobody pointed anywhere and keeps listing names that have since dropped. The names below are the exception: each was confirmed with a registrar.

Pronounceable, and unregistered when checkedchecked

Some registrar links earn us a commission. It never changes what you pay, and it plays no part in whether a name is shown as available.

Find your own

Nobody can search 11,881,376 names at once, and a tool that offered to would be lying — the largest plan here checks 10,000 in a run. What works is taking a corner of the space at a time: fix the first 3 letters and cross them with every two-letter ending, which is 676 combinations and runs on a free account.
