Paste domains or URLs separated by commas, spaces, or line breaks. We remove duplicates after normalizing the registered domains.
Each lookup stands alone.
An unavailable record won’t stop your batch. Results show the reason for each failed lookup and keep missing dates empty.

Sort the table by age or dates. Copy or export completed results with sources, timestamps, and errors for a transparent research record.
How to check domain age in bulk
Prepare a list of up to 50 distinct registered domains and paste it into the checker. Select Check domains to request their public registration records. Each row shows its own progress or error, so one unavailable record does not stop the rest of your batch.
When the batch completes, select a column heading to sort the results. Use Export CSV to keep a copy for a domain portfolio review, a website audit, or a shortlist you are researching. For a detailed view of one record, open the domain age checker.
Follow our bulk domain age research guide for list preparation, comparison tips, and a workflow for keeping source records with your CSV.
What the bulk lookup can and cannot tell you
Age is calculated from the creation date in the current registry record. The oldest domain in your list may have changed owners or hosted different websites. Registration age alone does not measure authority, trust, or search ranking potential.
Coverage depends on the registry's public RDAP service. We do not guess missing dates, and lookup failures remain in your export. Read about our registration data and calculation method before drawing conclusions from a comparison.
If a row is missing a date or returns an error, use the domain lookup troubleshooting guide to understand the response before retrying.
Frequently asked questions
Bulk domain age checker FAQs
How to check registration dates, understand website history, and put age in context for SEO.
More about our dataIs the bulk domain age checker free?
Yes. Check up to 50 domains per batch without signing up. You can sort, copy, and export results as CSV for free. Request limits and registry availability still apply.
Can I paste full website URLs?
Yes. Paste domains or URLs separated by spaces, commas, or line breaks. URLs and subdomains are normalized to the registered domain, and duplicates are removed before lookup. Different pages on the same domain share one registration record.
Why do some domains have no age?
A registry may not support public HTTPS RDAP, omit a creation date, restrict requests, or be temporarily unavailable. Missing dates stay empty, and failed lookups include an explanation. An unavailable result does not mean a domain is available to register.
Can I download the domain age results?
Yes. After the batch finishes, use Export CSV to download the results. The export includes available registration details, source URLs, retrieval times, and lookup errors so you can review the batch outside the checker.
Does the oldest domain have the best website?
No. Domain age measures time since the reported registration date. It does not verify current ownership, website quality, traffic, or search performance. Review website history and current content separately.
