..... huh?
If you were to go to the Schenectady Post Office and get the PO Box numbered 6789 then your mailing address would be:

that's not for PO Box numbers. I couldn't tell you what it's for but it's not PO Box #s. BTW, it is entirely possible to have 12345-6789, contrary to what's been said by the OP.
I've seen a lot of mailing addresses where the P.O. Box # matches the 12345-xxxx number - I think the number is supposed to be a routing code of some kind.
From Wiki:
A ZIP+4 code uses the basic 5-digit ZIP plus an additional 4-digits to identify a geographic segment within the 5-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery.
For Post Office boxes, the general (but not invariable) rule is that each box has its own ZIP+4 code. The add-on code is often either the last four digits of the box number or 0 plus the last three digits of the box number. However, there is no uniform rule, so the ZIP+4 code must be looked up individually for each box.
