"No record found" is not "available": how to check a .com before you fall for a name

You find a name you love, run a lookup, and the .com comes back "not found". Before you print the logo, it helps to know what that result does and does not tell you.

What a "not found" lookup means

RDAP is the protocol that replaced WHOIS for looking up domain registrations. When a registry's RDAP server answers "not found" (HTTP 404) for a .com, it means the registry had no registration record for that name at the moment you asked. Registries that document their RDAP service note that this usually means the name isn't registered, but not that it can necessarily be registered (SWITCH, the .ch registry; Register.si).

When a name still can't be bought normally

Cases that are not "not found" at all

Even dedicated tools get this wrong: one domain search tool reported at launch that about 1 in 20 names it showed as available were in fact taken, because of quirks in how it checked (Lean Domain Search, 2012).

A 3-step check before you commit

  1. Registrar search. Search the exact name at a registrar and confirm availability and the full price at checkout. A new .com typically costs around US$10–25 a year depending on the registrar; a price in the hundreds or thousands usually means a resale listing.
  2. Registration lookup. Confirm with ICANN Lookup: if a record exists, look at its status and dates.
  3. Trademarks. A free .com says nothing about trademarks. Search the markets you care about, for example the USPTO, EUIPO and WIPO Global Brand Database, and ask a lawyer for anything important.

Then register it before you share it widely.

Looking for names in the first place?

Browse new name ideas one at a time: short made-up names or meaningful two-word combos. Each card shows the date of a quick DNS pre-check of its .com, which is a filter, not proof that you can register it, plus a link to check it at a registrar. Free, no sign-up.
