Physical Stealth address

[two3aight1]

Quick question in regards to making stealth mercari accounts but this may apply to Eb and pp as well. So new address for each account, I get that part but wanting a physical address for each I go to ups store and open a new mailbox. Now if I open a ups box and get issued "134 whatever street unit 321" can I open another box at the same location and use a different unit number? Or just one account per street address?

different unit is fine.

Thanks appreciate it. Will give it a go. Didn't wanna drive all around town opening boxes.
