Domain Age API
WHOIS-Based Registration Lookups.
Look up the registration date and age of any domain name using live WHOIS data. Useful for SEO research, fraud detection, due diligence, and competitive analysis.
How Domain Age Detection Works
Every domain name has a registration date recorded in the global WHOIS database. We query that record in real time to tell you exactly how old a domain is.
WHOIS Lookup
When you check a domain, we query the global WHOIS database — the authoritative record of who registered a domain name and when. WHOIS data is maintained by registrars and updated within hours of any domain registration.
Registration Date
The WHOIS record contains the original registration date — the day the domain was first created. This date does not reset when a domain is transferred or renewed, making it a reliable indicator of true domain age.
Age Calculation
We calculate the exact age from the registration date to today, returning both years and days so you have precise data. Results are cached to keep the tool fast for popular domains.
API Documentation & Code Examples

Why Domain Age Matters
SEO & Search Rankings
Search engines factor domain age into trust and authority scores. Older domains with a consistent history tend to rank more easily for competitive keywords. If you are buying a domain or evaluating a competitor, domain age is a key signal.
Fraud Detection
Fraudsters and phishing operators routinely register new domains to avoid blacklists. A domain registered within the past 30–90 days is a significant risk signal. Combining domain age with IP intelligence gives you a powerful fraud scoring model.
Due Diligence
When evaluating a vendor, partner, or acquisition target, domain age reveals how long they have actually been operating online. A company claiming 10 years of experience with a 2-year-old domain is a red flag worth investigating.
Domain Age — FAQs
Common questions about domain age and the ip-api.io Domain Age API.
What is domain age?
Domain age is how long a domain name has been registered, measured from its original registration date to today. It is retrieved from WHOIS records maintained by domain registrars and registries worldwide. A domain registered in 1997 is considered very old; one registered last month is considered new.
Why does domain age matter for SEO?
Domain age is one of many signals search engines use when evaluating trust and authority. Older domains have typically accumulated more backlinks, content, and user history — all positive ranking signals. A newly registered domain must build that trust from scratch, which is why new sites take longer to rank for competitive keywords.
How do you check domain age?
You can check domain age using the free tool at the top of this page — enter any domain name and get the registration date and age instantly. For programmatic use, the ip-api.io Domain Age API at GET https://ip-api.io/api/v1/domain/age/{domain} returns the registration date, age in years, and age in days in JSON format.
Can domain age help detect fraud?
Yes. Very new domains — registered within the past 30 to 90 days — are frequently associated with phishing campaigns, spam, and fraud operations. Fraudsters register fresh domains to avoid blacklists. Checking domain age as part of fraud detection lets you flag or block interactions from suspiciously new domains before they cause harm.
Is the domain age checker free?
Yes, the interactive domain age checker tool on this page is completely free with no sign-up required. API access requires a paid subscription — see the pricing section for plans.
