Your domain host is the internet service that manages your website or the platform you bought the domain from. Your emails should have billing records and invoices related to the registration or transfer of domains.
If you’re unable to find your domain host, you can use a site like ICANN.
Visit: https://lookup.icann.org/ and enter your website’s URL.

Click on the Lookup button and you’ll find details about your domain like created date, expiration dates, and more. Perhaps, a little too much information. Scroll down to the Registrar Information section and you’ll find your domain host.

Alternatively, you can find the domain purchase receipt by signing in to your domain host service. Go to your Billing page and download the invoice in PDF format.
