It is possible to create a Google Business Profile without an address and have a service area. However, you won't be able to view citations in the platform without an address.
This is because the tool we use, Brightlocal, requires an address. Therefore, we are currently unable to show citations if your Google Business Profile has no address connected.
Please note, it's important not to use your home address as your business address, as this is against Google's privacy guidelines.
