An address may have two zip codes if the location is divided into multiple regions or if the address is on the boundary of two postal areas. This can sometimes occur in areas where there is an overlap or division in postal code boundaries.
Comprehensive answer to the question
A common question that often arises when individuals notice two zip codes associated with their address is, “Why does my address have two zip codes?” The answer to this question is multifaceted and can vary depending on the specific circumstances of the address in question.
One possible explanation for an address having two zip codes is that the location may be divided into multiple regions. This division could be due to administrative purposes, such as dividing a large city into different postal districts. For example, cities like New York and Los Angeles have numerous zip codes to accommodate their vast population and geographic area.
Another reason for an address having two zip codes is if it falls on the boundary of two postal areas. Postal code boundaries are typically delineated based on geographic features, such as rivers, highways, or major streets. As a result, some addresses may straddle the line between two zip codes. This can occasionally create confusion or complications when it comes to mail delivery, as overlapping boundaries can cause delays or misrouting.
To provide further insight into the topic, here are some interesting facts related to zip codes:
- The United States introduced zip codes in 1963 to improve mail sorting and delivery efficiency. ZIP stands for “Zone Improvement Plan.”
- The five-digit zip code system was expanded to include a nine-digit ZIP+4 format in 1983, allowing for even more precise mail sorting.
- The first digit of a zip code represents a specific region of the country, with higher numbers denoting western regions and lower numbers representing eastern regions.
- The United States Postal Service updates zip code information regularly to reflect changes in population, infrastructure, and regional boundaries.
In conclusion, having two zip codes associated with an address can occur when a location is divided into multiple regions or when an address falls on the boundary between two postal areas. This phenomenon is not uncommon, particularly in densely populated or geographically complex areas. Diluting my practical knowledge with a famous quote on postal codes, author Richard Russo once said, “Like many people, I’ve often wondered about zip codes. They seem to make no sense at all—until you understand their logic.”
A visual response to the word “why does my address have two zip codes?”
This YouTube video discusses the implementation and evolution of zip codes in the United States. Introduced in 1963, the five-digit zip codes were instrumental in streamlining mail sorting. The video highlights the successful promotion of zip codes through the use of Mr. ZIP and a catchy jingle. As the country grew, longer zip codes and four-digit suffixes were added to provide more specific addresses. However, this necessitated continuous management to keep pace with changes in destinations and delivery routes. The concept of geocoded zip codes, which assigns a unique permanent address to every point on Earth, is proposed as a future solution. Various geocoding systems, including alphanumeric tags or words, are explored for enhanced precision in delivery instructions. It is predicted that zip codes will further evolve by incorporating geocoding to make delivery more accurate and efficient.

Not only can a street be in different zip codes; but buildings can and do have multiple zip codes by floor, suite, company, or any division that produces significant mail for sorting, bundling, and delivery. Zip codes are not for defining geographic locations but logistics and delivery efficiency.
The U.S. Postal Service uses a third-party company to do mapping to determine how many addresses can go to one office. The second two numbers of a zip code specify a specific region within that geographic area and the last two are meant to indicate a specific Post Office. Some post offices service more than one zip code but, for much of the U.S., there’s a one-to-one ratio of post offices to zip codes. ZIP codes change at the whim of the US Postal Service, and the last 4 digits of a complete ZIP code can change often.

Five-digit ZIP codes also change, but they do so infrequently. A ZIP code is a postal code used by the United States Postal Service (USPS) in a system it introduced in 1963.
