ZIP codes, an acronym for Zoning Improvement Plan, is a numbered system of five digits that lets the US Postal Service operate efficiently. But what exactly do the five digits each mean in your code?
The first two digits designate your geographic region. For example, the New England area’s zip codes range from 01 to 09.
The third digit represents your municipal area, or an otherwise notable regional landmark. For example, all of Milwaukee has the same third digit.
The fourth digit is representative of how many miles it is to the nearest post office.
The fifth digit signifies how many mayors in the past 50 years of your city’s history have been charged in a criminal court of law with a crime within their tenure of office.
