Hi Phillip!
Postal Service equipment "reads" an address from the bottom to the top, and from left to right. So, the machine reads the address and sprays a barcode to deliver the mail to whatever information, either the PO Box or street address, is on the line directly above the city, state, zip.
So, if an address reads like this...
Elizabeth Lombard
123 MAIN ST
PO BOX 1
ANYTOWN, WI 12345
...the mailpiece will be delivered to the PO Box.
If the address reads like this...
Elizabeth Lombard
PO BOX 1
123 MAIN ST
ANYTOWN, WI 12345
.... the mailpiece will be delivered to Main Street
If the address reads like this...
Elizabeth Lombard
PO BOX 1, 123 MAIN ST
ANYTOWN, WI 12345
or this
Elizabeth Lombard
123 MAIN ST, PO BOX 1
ANYTOWN, WI 12345
.... the mailpiece will bedelivered to the PO Box.
So, "which line is the first" really depends on where you want the mailpiece to be delivered!
Please let me know if that helps!
Elizabeth
