Anyone know how to complete the new registration process

forgive me if I come off like an absoloute noob (I am) and these will probably be very stupid questions, submitted my application and it bounced back with some changes required, also assuming this is new because old posts i’m trying to use to help are using different terms.

1. ⁠it’s asking me for a company registration number, I submitted an EIN but should I put my business identification number instead? it’s also saying in the little help hover button to “mention the unified social credit code found on your business license” is this different from my BIN / EIN and do I literally put in my bin / ein and on the same line put whatever this social credit code is?

2. ⁠asked for rent receipts but the only thing I could find on my resident dashboard was a utility bill, I thought great so I uploaded the utility bill but amazon only let’s me upload individual utilities or a bank statement which is a bit annoying (ex: electricity bill, water bill) but my utility bill includes all of this with the address included so I uploaded this under electricity but it rejected it. should I just use a bank statement?

apologies again, just trying to receive confirmation of anything before I submit and wait another few days, curious about anyone else’s experience.
