# Domain Availability Checker

Check whether a domain is available, and for a registered one see its age, its expiry date and the status codes that hold it, from the registry (RDAP).

## Capabilities and processing

Enter a domain or paste RDAP JSON. A domain is sent to our server, which asks the registry’s RDAP service; pasted JSON is read in your browser.

An RDAP not-found response is reported as no registration found; it does not guarantee that the name can be registered. For a registered name, the page shows its age, a timeline from registration to expiry, the registrar and every status code in plain words, including the expiry stages: auto-renew, redemption and pending delete.

## Example workflow

The sample domain was registered in 2011 and is transfer-locked. Break it shows a free name, one expiring in two weeks, one in redemption with an estimated drop date, and one registered last week.

## Limits and interpretation

Price, premium and reserved names are the registrar’s to say. Drop dates after redemption are estimates. Nothing is stored.
