What this tool checks
Domain age
Calculates elapsed time from the registration event date when the registry supplies one.
Registration details
Displays creation date, expiry date and registrar when those fields are publicly available.
Bulk workflow
Deduplicates input, validates domain syntax and lets you download results as a CSV spreadsheet.
Important notes
- Domain age is based on the registration date returned by RDAP; it is not necessarily the age of the website or its SEO authority.
- Public RDAP services may rate-limit requests or omit dates and registrar details. Large batches may take time.
- This page uses the IANA RDAP DNS bootstrap registry to find the appropriate registration-data service. It does not require a paid API key.
- Do not use this tool to infer ownership history. A domain can change owners or be re-registered.
