Domain Age Checker
Check when an email domain was first registered. New domains are riskier — established domains are more trustworthy.
What is Domain Age?
Domain age refers to how long a domain name has been registered. It's determined by looking up the domain's WHOIS or RDAP registration record to find the original creation date. For example, google.com was registered in 1997, making it over 25 years old.
Domain age is a significant trust signal in email validation. Legitimate businesses and organizations typically have domains that are months or years old. In contrast, domains created within the last 30 days are statistically much more likely to be associated with spam, phishing, or fraud — spammers frequently register new domains to avoid reputation-based blocking.
Our tool queries the RDAP (Registration Data Access Protocol) database, which is the modern, structured replacement for WHOIS, to retrieve the domain's registration date and calculate its age.
Why Does Domain Age Matter?
Many spam filters use domain age as a factor in their scoring. A domain less than 30 days old sending bulk email is a strong spam indicator. Email service providers like Google and Microsoft give preferential treatment to older, established domains with clean sending histories.
For B2B email validation, domain age helps assess the legitimacy of a contact. A prospect email from a domain registered last week deserves more scrutiny than one from a 10-year-old domain. Combined with other checks, domain age provides valuable context about sender trustworthiness.
Frequently Asked Questions
How old should a domain be to be trusted?
There's no hard cutoff, but generally: domains under 30 days are high risk, 30-365 days are moderate risk, and domains over a year old have established some history. Of course, domain age alone doesn't determine trustworthiness — a new legitimate business will have a new domain.
Why can't you find the age of some domains?
Some top-level domains (TLDs) don't publish RDAP data, or their registrars may not include creation dates. Country-code TLDs like .uk, .de, and .jp have varying levels of RDAP support. In these cases, we report the age as unknown.
Can domain age be faked?
Not directly, since registration dates are maintained by registrars. However, spammers sometimes purchase expired or aged domains to inherit their age and reputation. This is why domain age should be one factor among many in a comprehensive email validation approach.
