To make room for everyone and their dog, it has been necessary to expand the system.The "plus 4 part" comes in.We're getting ahead of ourselves, so let's start with the basics.
You're familiar with these codes.They look like a destination post office.Here's why.
If you're mailing a letter from Boston to Seattle, the mail carrier in Massachusetts doesn't care about the street address of the destination.It's outside his jurisdiction.The other carrier can get it to that address if he knows the mail carrier that will send it.
On a given day, a postal worker can only cover so much ground.Since the USPS has a standard of delivering in rain, sleet or snow, there is no chance of doing the service in stages.Any post office can only serve what it can reach in a day.ZIP codes reflect that.
Every one of the latter has a ZIP Code that is tied to a post office.ZIP Codes can be used as a mailing address for a post office.One-on-one game plans are the norm, even though some do handle more than one ZIP Code.
ZIP Codes are not "boundaries."They are a collection of delivery routes.They don't follow geographic or administrative boundary lines.They follow the delivery trucks.
ZIP Codes can be special."military" ZIP Codes include everything from military bases to battleships at sea.There are unique codes.The volume of mail can cause businesses and organizations to have their own ZIP Codes.Since the organization usually has a mail department that presorts mail before giving it to the USPS, they are often benefiting from bulk mailing discounts."military" and "unique" ZIP Codes circumscribe their own delivery areas.
ZIP codes are used to ensure the fastest, most accurate mailing possible.Once the address has been proven real, they're provided.The actual path the mail truck would travel in a single drop-off is indicated by the codes.This usually includes ten to twenty homes or locations.ZIP+4 codes are assigned to PO boxes.Each PO Box has its own +4 Code, which often matches the box number.
