How to Find When a Domain Was Registered (Domain Age, One or Many)

A domain's registration date is the created date in its registry record. Paste one domain or a whole list into the bulk WHOIS lookup: each is looked up over RDAP on its registry's own server, and you get created, updated and expiry dates, registrar, status codes and nameservers in one table, with CSV export.

Find the created date with the bulk lookup

1. Open the bulk WHOIS lookup.
2. Paste domains, email addresses or website URLs, one per line, or upload a CSV of up to 5,000 rows and 500 unique domains. Addresses and URLs are trimmed to the registered domain.
3. Press Look up WHOIS records. Only the unique domains are sent, 20 at a time.
4. Read the created column, and sort by it to put the youngest domains first.
5. Download the CSV.

Find it by hand

whois google.com | grep -i "creation date"
#   Creation Date: 1997-09-15T04:00:00Z

curl -s https://rdap.verisign.com/com/v1/domain/google.com \
  | jq -r '.events[] | select(.eventAction=="registration") | .eventDate'
# 1997-09-15T04:00:00Z

RDAP calls the created date the registration event. Each TLD's RDAP server is in IANA's bootstrap file; TLDs missing from it, such as .io and .de when we checked on 8 November 2026, need the registry's WHOIS.

What the created date tells you

• It's the current registration. If a domain lapsed and someone registered it again, the date restarts. An old company can show a young domain, and a recently re-registered domain can carry someone else's history.
• A very young domain on a lead list is worth a closer look: new companies, but also throwaway domains. See domain age in lead scoring.
• For your own sending domains, age is one of several things mailbox providers weigh. See how old a domain should be for cold email.

Next step: check the mailboxes, not just the domain

A domain's age says nothing about whether a given address on it exists. Upload the list at /verify to check every mailbox without sending. The first 100 checks are free with a Google sign-in, no card.

*Fair use: the first 100,000 checks a month at full speed, then slower, never cut off.
