I recently formed my LLC online and used a PO Box as the main business address. I am trying to keep my personal info seperate from my buisness. I used the PO Box as the address in all required address sections for the LLC. I did not have to use my home address at all. What addresss do I use for the EIN if the only adresss listed on the business cert is a PO Box and the online application will not allow a PO Box??
