1723 E Lombard 21231-1809-23-8 1723 W Lombard 21223-2314-23-5 1723 W Hollins 21223-2310-23-9 as you can see the zips for W Hollins and W Lombard are similar, but if there is a barcode printed in the address or one of those sprayed/labeled on orange barcode down at the right bottom, this shouldn't be an issue. I would guess the guy sorting mail into his bag just stuck that handfull of mail in the wrong part of his street walking sequence. (in case anyone is wondering about the "zip12" numbers, the pair o digits are the delivery point in the zip4 area, usually the last two digits of street number for single family residences, and the last digit is a check digit [all digits add to mod 10 = 0])
