In short. Whether a domain is free or taken is shown by WHOIS — the domain-name registration database. If a name returns a registration date and a registrar, the domain is taken; a "No match" / "no data" answer means the name is free to register. The check takes a minute and needs no trip to a registrar. Mind two traps: a name can be free in .com but taken in .net (and vice versa), and "taken" doesn't mean "in use" — domains are often held in reserve or resold. Below is how to check correctly and what to do if the name is taken.
What "domain is taken" means
Every domain name is unique within its zone: example.com can belong to only one owner. When someone registers a name with an accredited registrar, it enters the zone registry and becomes unavailable for re-registration as long as the owner keeps paying to renew. "Taken" is exactly that registry entry.
You don't buy a domain forever — you rent it. While the owner renews, the name is taken; the moment they stop paying, it goes through a grace period and returns to the free pool.
Don't confuse "taken" with "in use." A huge share of registered domains point to no site at all: held in reserve, bought for resale (domaining), or abandoned but not yet released. So a blank page at an address is no sign the name is free.
Check in a minute
Method 1 — WHOIS. The most reliable. Enter the name in a WHOIS lookup and read the answer:
- A
Creation Date, registrar, status — the domain is taken. You'll also see when the registration expires (Registry Expiry Date) — sometimes a name is about to be released. - "No match for domain" / "No entries found" / empty answer — the name is free to register.
# from the terminal — the same thing:
whois example.com | grep -iE 'created|expiry|registrar|status'
# empty or "No match" = the domain is freeHow to read the remaining fields is in the WHOIS guide.
Method 2 — registrar search. Every registrar has a lookup form: type a name, it shows free zones and prices. Handy when you want to register right away, but remember the registrar is in the business of selling, so it actively pushes "similar" paid options.
WHOIS answers "is the name taken," a registrar answers "how much to register it." For a cold check, start with WHOIS: it's neutral and shows registry facts, not a storefront.
Check several zones at once
A name being free in one zone says nothing about others. myshop.com may be taken while myshop.store, myshop.io or myshop.shop are free — and vice versa. Before choosing, run the name across at least the key zones:
| Zone | For | Note |
|---|---|---|
| .com | International project, recognition | The most crowded zone — short names are nearly all gone |
| .store / .online / .shop | Online stores | Freer and cheaper up front, but pricier to renew |
| .io / .dev / .app | IT products, startups | Pricier; .dev and .app require HTTPS (on the HSTS-preload list) |
| ccTLD (.de, .co.uk…) | Local business, regional audience | Some require local presence or documents to register |
How to pick a name and zone for the job is in the domain-choosing guide.
The name is taken — what to do
- Take another zone. The fastest path:
.comis taken — take.store,.ioor a country zone. Check the name is also free there and doesn't point to a competitor. - See if the domain is being released. WHOIS shows the expiry date. If registration ends soon and the owner isn't renewing, the name goes through a grace period and returns to the free pool. You can place a backorder with a registrar.
- Buy it from the owner. If the name is essential, find the contact in WHOIS (or via the registrar's form when data is masked by privacy) and offer to buy. Be ready — domainers hold desirable names precisely for resale.
- Change the name. Adding a word, a region, or a short prefix is often smarter and cheaper than fighting for a taken name.
Frequently asked questions
WHOIS says free, but the registrar says "taken." Who's right?
Usually the registrar — registry data updates with a lag, and the name may have just been reserved or submitted for registration. The reverse happens too: WHOIS shows it taken while the site doesn't work — that's "taken but not in use." Trust the registration attempt: if the system won't let you register, it's taken.
Why doesn't WHOIS show the owner?
Privacy. For individuals' domains, many registrars and zones mask personal data (GDPR for international zones, private-registration options everywhere). The name, date, and registrar are always visible; the contact is often reachable only via the registrar's form.
Has someone taken my brand in other zones?
Worth checking: typosquatters and competitors register brands in adjacent zones for phishing or resale. Run your name across .com, country zones, and popular new zones via WHOIS, and put your main domain on expiry monitoring so you don't lose it yourself.
Checklist to remember
- Availability is shown by WHOIS: a registration date means taken, "No match" means free.
- "Taken" ≠ "in use": a blank site at an address doesn't mean the name is free.
- Check several zones at once — free in
.comdoesn't guarantee.io. - Taken — take another zone, wait for release (grace period), or buy it.
- Keep your own domain on expiry monitoring so you don't lose it by inattention.
