Best Free Domain Age Checkers (2026): How They Differ and Which to Trust

Every domain age checker answers the same question: when was this domain registered? Most of them read the same public registration data, so the differences are not in "accuracy" but in what else they show: history, bulk checks, ccTLD support, and whether they tell you where the date came from.

Before comparing, one thing to keep in mind. Domain age is the creation date of the current registration, not the age of the website and not a measure of trust. If a domain expired and someone registered it again, the clock restarts. If it changed registrar, the creation date normally stays. And an old domain can host a brand-new scam after it changes hands. Our guide on what domain age really means covers this in detail.

Where the date comes from: RDAP and WHOIS

Registries publish registration data through two protocols. WHOIS is the old text protocol; every registry formats it differently. RDAP is its structured successor (JSON over HTTPS), now the standard for generic TLDs such as .com. A good checker uses RDAP first and falls back to WHOIS. Country-code registries (.uk, .de, .pl, .ua and others) set their own rules, and some publish only part of the data.

The tools, by what they are best at

ICANN Lookup — best for the authoritative current record

ICANN Lookup is ICANN’s own registration data tool for domain names and IP resources. It queries RDAP, so for gTLDs you get the registry’s structured answer with creation, expiry and last-changed dates, registrar and status codes. It does not calculate the age for you and has no history, but when two checkers disagree, this is the record to trust.

WhoisXML API — best for registration history

A plain age check cannot tell you whether a domain dropped and was re-registered, or changed owners. WhoisXML API’s WHOIS History can: the company says it holds an archive of more than 28.7 billion WHOIS records and gives 500 free API credits with no credit card. You need an account. Use it when you are judging an expired domain before buying it or investigating who was behind a site.

Wayback Machine — best for what the domain hosted before

The Wayback Machine does not show registration data at all, and that is exactly why it belongs here. Its archive of more than a trillion web pages shows what the domain displayed over the years. A 15-year-old domain whose first snapshot is from last month, or which hosted a casino before becoming a "family bakery", tells you more than the creation date alone.

SmallSEOTools Domain Age Checker — best for small batches

SmallSEOTools lets you enter up to 10 domains at once. According to the page, the report shows age, creation, expiry and update dates, registrar, IP address, name servers and a link to the domain’s Wayback history. That makes it convenient for comparing a short list of competitors. The page does not publish daily limits.

PromoPilot Domain Age — best for age plus expiry at a glance

Our Domain Age checker queries RDAP first (via rdap.org) and, if no creation date comes back, asks the registry’s WHOIS server directly. It reduces subdomains to the registrable domain, including second-level zones such as com.ua, co.uk or com.pl, which some checkers get wrong. The result shows age in days and years, creation, expiry and last-updated dates, registrar, and a colour badge with the days left until expiry. For a broader picture use the full WHOIS lookup or the domain trust check.

Whois.com — best for reading the raw record

Whois.com is a public WHOIS lookup for domains and IPs, run by a company that also sells domains and hosting. It is a fast way to see the full record as text, including fields that age checkers hide. It does not compute age or keep history, and the page does not publish limits.

What the dates in a record mean

• Creation (registration) date: when the current registration started. This is what "domain age" is calculated from.
• Updated (last changed) date: the last time the record changed. Renewals, name server changes and contact updates all move it, so a recent date here says little on its own.
• Expiry date: when the registration ends unless it is renewed. Most domains renew automatically, so a near expiry date is not suspicious by itself, but for your own domains it is the date that matters.
• Registrar and status codes: who manages the registration and whether it is locked against transfers or on hold. A domain on hold usually does not resolve at all.

Why checkers sometimes show different ages

• Re-registration. After a drop, the registry shows the new creation date. History services may still show the old one.
• ccTLD rules. Some country registries do not publish a creation date over RDAP or WHOIS, or publish it in their own format. A checker may then show nothing or fall back to another field.
• Wrong domain parsed. A checker that treats shop.example.co.uk as co.uk returns nonsense.
• Time zones and caches. Small differences of a day usually come from UTC conversion or cached records.

How to choose

1. Just need the date? Any RDAP-based checker. Confirm disagreements in ICANN Lookup (gTLDs) or the national registry (ccTLDs).
2. Checking whether a shop is legit? Combine age with the other signals in our guide on how to check if a website is legit. A young domain is a reason to look harder, not proof of fraud.
3. Buying an expired domain? You need history: WHOIS history plus the Wayback Machine.
4. Monitoring your own domain? Watch the expiry date, not the age.

What our tool does not do

• No history: it shows the current registration only, so a dropped and re-registered domain looks young.
• One domain per check, no bulk mode. Limits: 15 checks a day without an account, 45 with a free account, no daily cap on Pro.
• If the registry publishes no creation date, we cannot show the age, and we say so instead of guessing.
