This website says yes, one zip code may lies in more than one cities.

What do you think of this?

Answer 1

Actually, yes, one zip code can be located in more than one city in the same state if they are connected to each other or in close proximity, depending upon population and growth after the zip code was designated for that area (annexes can create this situation). Also one zip code can be used for the same area even though that area might go by several different "city" names. For example: 63124 and 63105 can be St Louis (as they are located within the greater metro area - all "631" zips can be properly designated as "Saint Louis" even though many are not in the actual city limits but are located in the greater surrounding area of the same county), and 63124 and 63105 are also located in the City of Clayton. Even though Clayton is in the greater St Louis metro area, it acts as the hub of the suburban county area surrounding the city proper of St Louis, and has its own judicial system, police department, board of elections, mayor, etc, and is considered a city itself. Many of the smaller municipalities use Clayton's courthouse, jail, etc, and it has its own parks system as well.
My own zip code has 3 options, two of which are "cities" and the other choice is a suburban area surrounding St Louis. I live in a "4th class incorporated city" which among other things means we share a tax base with several other smaller cities - they are not called towns, they are called "the city of" in each case - there is a difference in the classifications between towns, smaller cities and municipalities - but it is too technical and complicated to even try to explain, and there are more criteria than just size or population in the determination.
The mail will get to the proper destination if you have the proper zip code and street address regardless of which choice of city is used, as the zip code and street address are what the post office goes by the most.
The link is a zip code/city/address search site with the US Postal Service. Try it for yourself, enter any zip code and you will find that some of them do in fact allow several different names for the same area. Save the zip4 link as a favorite, it may come in handy sometime.

Answer 2

Zip Code

Answer 3

Zip codes are regional without regard to other political boundries. An underpopulated zip code area may be very large and contain several small towns, just like an over populated zip code may only cover a few blocks of a busy city. However, zip codes are never repeated so it would be impossible for mail to be misdirected because of duplicate zip codes.

Answer 4

Zip codes don't cross state boundaries. Within a state, they can cover several small towns, which would mean the same zip code was being used in multiple places. Note however that if the same zip covers 2 or more towns, it will also cover part or most of the area between those towns. You won't have two towns with the same zip code in different parts of the state.

Zip codes don't cover more than one city, however, since the population is too high. In fact, most cities have several zip codes, the largest (NYC, Chicago), have dozens or hundreds. As an example, the Empire State Building in NYC has its own zip code, as did each tower of the World Trade Center.

Answer 5

Yes, this is true. A ZIP Code I know of, 33436, covers both Boynton Beach and Hypoluxo, FL.

Answer 6

The objective of zip codes is to accurately describe the exact location where something is to be sent, how much sense would it make to have a code that was available in two or more different areas?

Answer 7

every city has a different zip code this is fact ?

Answer 8

Yes, but not "cities"... small towns. I once lived in a zip code that encompassed four small towns along the beach near Galveston Tx. All four towns got their mail at one post office.

Answer 9

Yes.

For example, 49544 can be for Walker, MI or Grand Rapids, MI. In fact, if you live there, you could use Walker or Grand Rapids as your address. Such as...

123 Main Street
Walker, MI 49544

...or...

123 Main Street
Grand Rapids, MI 49544

There are a lot of zip codes around Grand Rapids like this, which suburban communities share with Grand Rapids (Walker, Kentwood, etc.).

Answer 10

Many cities - no, because a city implies a minimum population. A number of small towns in the same rural county - yes.

Answer 11

Don't think so. You start with the small numbers on the northeast coast and work your way to the large numbers on the west coast.
