The term 'Postal Division' can be broken down into two parts: 'Postal' and 'ZONE'. The Postal ZONE is a geographic area used by the United States Postal Service (USPS) to efficiently deliver mail. It is divided into ten numbered zones, with each ZONE covering a different region of the country. The USPS assigns a specific ZONE number to each address in order to ensure that mail is delivered to the correct location. The Postal ZONE system is an important part of the USPS's operations, as it helps to ensure that mail is delivered quickly and accurately.
