How to Fix the “CPF Is Already in Use” Error for .br Domains at Hostinger

Using a unique CPF for .br domain registration

Updated 1 week ago

If you are registering a .br domain (including .com.br, .org.br, etc.), you may get the CPF is already in use. Enter unique CPF message:

This means that the CPF entered has already been previously used. For security reasons, each CPF/CNPJ can only be associated with one Hostinger account. To solve this, you need to register the domain with a different CPF or CNPJ.

It can be that you have another Hostinger account where you’ve used the CPF/CNPJ for domain registration previously. If you want to use the same CPF/CNPJ for the new domain registration, you should cancel that new domain order while the domain is refundable and create it again on the account with the CPF associated with it.

How to Check Which Domains Are Registered Under Your CPF/CNPJ

If you’re unsure which Hostinger account your CPF/CNPJ is linked to, you can check your registered domains directly from the Registro.br panel. Here’s how:

  1. Go to registro.br and log in using the CPF or CNPJ you are trying to use to register a domain at Hostinger. If this is your first time logging in or you can’t remember your password, click on “I can’t remember or I don’t have the password” and reset it.
  2. Once logged in, click on “Domains” at the top of the page.
  3. Take a screenshot of the list of domains that appear and share it with our support team.

Our team will use this information to identify which Hostinger account was originally used with that CPF/CNPJ and guide you through the next steps.
