Register your business officially in your country with a business address. For example, relocating where you have your business operation to not be your residential address.
Google allows trustworthy businesses only, by not listing the address of operation, you will not be able to follow the policy requirements and trust levels.
Our business is legally registered in our country but it's registered at our home address. So your saying I need to rent/buy a property to have a business address I'm willing to list just so Google will allow it?
Surely there is another way. Can I provide an email and phone number instead and use a PO box for returns?
I am saying you need to use the address that is officially registered, be it at home, or at a different property.
PO boxes, co working spaces, virtual offices, distribution centers are all generally not accepted.
A valid address that can be resolved in Google Maps, is only one of many requirements to get approved by Google.
If you are already suspended, you need to go the extra mile as you will be more scrutinized compared to a company that has a long track record of order fulfillment.
When you are already suspended, you need to go the extra mile. So just following the bare minimum, will most likely not work. I help hundreds of merchants and the ones that only do partial or try to limit what they do, pretty much all fail.
If you want to add a return address, that is different from the business address, sure that is fine. However on the contact page, you must add all contact methods, including address, phone, business hours, contact form and email address.
I want to update this thread that drop shipping is no longer cause of suspension. A google CM has confirmed with us product experts that this is not a reason for suspension.
