"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

• Someone registers it after your check. A lookup is a snapshot. Good short names can go between your search and your checkout.
• The registry reserves it. Some .com labels are reserved from initial registration unless ICANN authorizes their release (.com Registry Agreement 2024, Appendix 6).
• The lookup itself failed. A timeout, a rate limit or a tool that queries the wrong server can look like "not found" if the tool doesn't tell the cases apart. Treat any result without a clear source and time as unknown.

Cases that are not "not found" at all

• Expiring names. A .com in redemptionPeriod or pendingDelete still has a registration record; it only becomes registrable after the registry deletes it (ICANN, EPP status codes).
• "Premium" or "for sale" .com names. These are usually already registered and listed for resale by their owner. That is a purchase from a person, at their price, not a new registration.
• Names with no website. A name that doesn't load can still be registered; a registered .com may have no name servers at all (status inactive in the same ICANN list).

Even dedicated tools get this wrong: one domain search tool reported at its 2012 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 at checkout that it can be registered: check the first-year price, the renewal price, taxes, and whether it is 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.
