You can follow the instructions below to transfer your domain from NameCheap to Cloudflare.
To transfer to a new registrar, your domain must meet the following requirements.
If it is listed as available for transfer in the Cloudflare dashboard, these restrictions have already been checked.
Cloudflare Registrar does not currently support email forwarding. If you require email forwarding from your registrar, you will need to use a third-party forwarding service and configure your MX record in the Cloudflare DNS setting for the domain.
Login to the Namecheap account where the domain is registered. Navigate to the Domain List page and select “Manage”.
Select the Sharing & Transfer tab. In that tab, you will find a card labeled “Transfer Out”. First, click “Unlock” next to “Domain Lock”.
Customers must remove “WhoisGuard” from NameCheap prior to transferring the domain.
While still on the Sharing & Transfer tab, click the button “Auth Code” next to “Domain Lock”. Namecheap will email the code to the email on file for your account.
In the Cloudflare transfer screen, input the authorization code. Each domain will have a unique authorization code and you will need to enter each for every domain you want to transfer.
Once Cloudflare processes your transfer, Namecheap will send an email to the domain’s registrant contact (the same address where the authorization code was emailed). The email will contain a link that you can click to immediately approve and process the transfer. If you do not click the link, the transfer will automatically approve within 5 days.
