Yes but how does this work? How do they match the ABN being entered to eBay sellers? I cannot see any way they have personalised this form - even though I received one for each eBay store email address I use. It looks like a generic form and as I mentioned previously business name is optional. Surely a better way to do it would for sellers to add the ABN to their seller's account. Someone sent a link through earlier (3 in fact) to the same form, what's to stop someone here using those links to enter their ABN. I don't really understand how they can match the ABN to the seller. I have one ABN that is related to two eBay stores and one registered business. Very badly communicated email.
