I tried to purchase postage online to mail a stand-alone I-130 to Chicago. The I-130 instructions say the zip code is 60680-4107, but the online post office verification system says the zip for that PO Box should be 60680-4143. I called the Post Office 800 number and they verified they have 4143 as the +4 for the PO Box address. Has anyone had any issues with the Chicago lockbox receiving their package due to a different ZIP+4?
Post Office has a different ZIP+4 then on the instructions
