If you transfer your domain to HostPapa as your primary domain, this can be your free domain registration. HostPapa will renew this domain on your behalf as long as you pay the renewal fees each year thereafter. If you decide to leave HostPapa within the first year, there is a one-time domain transfer administration fee.

Alternatively, you may register a brand new domain for free and then “addon” or “park” your existing domain name for free in your cPanel.
Here is a link to more information about “addon” and “parked” domains: https://www.hostpapa.co.uk/knowledgebase/kb/the-difference-between-addon-domains-parked-domains-and-subdomains/
Note: HostPapa provides one free domain registration for the first year. All other domains registered through HostPapa on your account are subject to annual domain registration fees.
