Adapt Zip Code Notice For Free

This is because ZIP code boundaries are based on mail routes and delivery points rather than geographic factors. The U.S. Post Office Department, predecessor to USPS, developed a zoning address system in 1943 as a way to make sorting and delivery of mail easier.

There are over 100 cases where ZIP codes cross state lines. Even if ZIP codes could be plotted with well-defined boundaries, these would not align with other political boundaries such as county or municipal borders. And ZIP codes certainly do not align with United States Census tracks, block groups, or blocks.

Not Always. When looking at postal codes around the world, there are cases where two different cities are served by the same postal code. For example, the zip code 94608 in California is used for both Emeryville and parts of Oakland. One postal code, two cities.

Place the city, state, and ZIP Code in that order on the last line. This must be the last line. Never place an ?attention line,? telephone number, or other entries after the ZIP Code line.

Since our caller works for the U.S. government, and ZIP codes are a government thing, I checked the US Printing Office style guide first. It recommends ?ZIP Code.? Associated Press style is similar: ?ZIP code??two words with ?ZIP? in all caps?but it uses a lowercase C, and I was surprised it would deviate.

When the machine asks for a zip code, try entering the three consecutive numbers of your postal code followed by two zeros. For example, the postal code M5J 1E3 translates into the zipcode 51300.

ZIP Codes are numbered with the first digit representing a certain group of U.S. states, the second and third digits together representing a region in that group (or perhaps a large city) and the fourth and fifth digits representing a group of delivery addresses within that region.
