History of the ZIP Code

During World War II, thousands of experienced postal employees left to serve with the military. To offset the loss, in May 1943 the Post Office Department began a zoning address system in 124 of the largest cities. Under this system, delivery units or zones were identified by one or two numbers between the city and state — for example, Birmingham 7, Alabama — so that mail could be separated by employees who did not have detailed scheme knowledge.

Twenty years later, the Department implemented an even farther reaching plan, the Zoning Improvement Plan (ZIP) Code.

The social correspondence of the 19th century had given way, gradually then explosively, to business mail. By 1963, 80 percent of all mail in the United States was business mail. The development of the computer brought centralization of accounts and sent a growing mass of utility bills and payments, bank deposits and receipts, advertising, magazines, credit card transactions, mortgage bills and payments, and Social Security checks through the mail. Yet while mail volume grew and while the Post Office Department had been at the forefront of advances in transportation, the methods and much of the equipment used to sort mail in thousands of Post Offices remained the same as in Benjamin Franklin’s day. A better way to sort mail was needed.

In June 1962, after a study of mechanization, the presidentially appointed Advisory Board of the Post Office Department made several recommendations. One was the development of a coding system, an idea the Department had considered for a decade or more. A number of coding programs were examined and discarded before the Department selected a system advanced by Department officials. Postmaster General J. Edward Day announced that the ZIP Code would launch July 1, 1963.

Preparing for the new system involved a realignment of the mail system. The Post Office Department had previously recognized that new avenues of transportation would open and had begun to establish focal points for air, highway, and rail transportation. Called the Metro System, these transportation centers were set up around 85 of the country’s larger cities to deflect mail from congested city streets. The Metro concept was expanded and eventually became the core of 552 sectional centers, each serving between 40 and 150 surrounding Post Offices.

Once these sectional centers were delineated, the next step in establishing the ZIP Code was to assign codes to the centers and the postal addresses they served. The existence of postal zones in the larger cities, set in motion in 1943, helped to some extent, but in cases where the old zones failed to fit within the delivery areas, new numbers had to be assigned.

By July 1963, a five-digit code had been assigned to every address throughout the country. The first digit designated a broad geographical area of the United States, ranging from zero for the Northeast to nine for the far West. This number was followed by two digits that more closely pinpointed population concentrations and those sectional centers accessible to common transportation networks. The final two digits designated small Post Offices or postal zones in larger zoned cities.

The ZIP Code began as scheduled. At first, use of the new code was not mandatory for anyone, but in 1967, the Department required mailers of second- and third-class bulk mail to presort by ZIP Code. The public and business mailers alike adapted well to its use.

How to Find USPS ZIP Codes

by Ashley Donohoe

Published on 11 Feb 2020

When sending your business mail, it’s important to include the ZIP Codes for your business and the recipient on the package or envelope so your item moves efficiently through the postal system. While the USPS might still process mail without the ZIP Code, you risk both delays and potentially lost mail. For your convenience, you can use the USPS ZIP Code locator tool, which you can access through the «Quick Tools» menu option on the USPS website.

Tip

The USPS website has a tool you can use to easily find a ZIP Code by address or city. You can also obtain the ZIP Code through online research and communication with the company.

How USPS ZIP Codes Work

The postal service implemented the first form of ZIP Codes in the 1940s to make it easier to sort mail by city and state. While these numbers first had just two digits, they expanded to the standard five-digit ZIP Codes we see today. USPS eventually added four additional digits separated with a hyphen — called a ZIP+4 Code — to provide more specific details about the destination.

The USPS breaks down a ZIP+4 Code as follows:

• The first three digits will refer to a large area, like a city.
• The last two digits before the hyphen will point to a specific delivery area or local post office.
• The first two digits after the hyphen refer to city blocks or a particular sector.
• The last two digits might refer to a specific part of a street or a sector.

Find ZIP Code by Address

As long as you can locate everything about the address except for the ZIP Code, you can simply perform a USPS ZIP Code search by address. Click the «Find by Address» button on the USPS tool and type the full street address with city and state at a minimum. You can also enter the company name and any suite or floor number. Click «Find» to see the USPS-formatted address with the five-digit ZIP Code and its extra four digits.

If the tool reports an error finding that particular address, try leaving off the company name and search again. You might also use a search engine to verify the street number and name, suite number and neighborhood.

Search by City and State

If you’re curious about the ZIP Codes that span a particular city, go to the USPS ZIP Code search tool and select the button to «Find by City & State«. After you type the city name, choose the state from the menu and click «Find.» You’ll then see each ZIP Code that matches that location.

While a small town may list just one ZIP Code, large cities can have a ZIP Code list with dozens of results, and you’ll need to navigate through several pages. USPS will also identify any special ZIP Codes reserved for PO Box usage.

USPS ZIP Code Finder Alternatives

While you’ll very likely find the ZIP Code you need using these methods, you do have a few alternatives to consider:

• Do a web search: When you type the business’s name into Google, Yahoo or Bing, you’ll often see a special local result that shows the address with ZIP Code along with the company’s website, reviews, phone number and other details. You can also go to the company’s official website and find the contact page that should show the full address. However, such methods may not show the ZIP Code’s extra four digits if you need them.

• Check previous mail and documents: If the company has sent you mail before, you could check letters and envelopes to see the sender’s ZIP Code. Documents such as advertisements, invoices and catalogs may also have this information.

• Contact the company: If the business has little presence on the web, look up the phone number and give them a call to ask for the ZIP Code. You can also ask in person if possible.

How to Find Postal Codes and Area Codes Online

Postal codes are numeric codes used to facilitate mail delivery, and code codes are used to indicate a geographic region when calling a phone number. Instead of flipping through a big, cumbersome phone book, you can easily find and check postcodes and area codes online.

How to find a zip code

USPS zip code lookup: If you have an address or a partial address, you can find a zip code through the Postal Service website. You can also search by city or state, or find all cities that are part of a specific zip code. nine0003

International Postal Codes Site maintained by Columbia University: Here you can find an extensive index of domestic as well as international postcodes, in addition to postal abbreviations, policies and best practices.

You can also use various search engines to look up postcodes:

Google: enter a partial address on Google and you will see a location map with the postal code included; you can even enter something like Postcode South Laurel MD to see them all in this area. You can also enter a zip code to see the geographic location it belongs to, as well as a map and other related web results, such as cities that use that zip code.

If you don’t add zip code at the end of a Google search, it may show unrelated information. For example, searching for

reveals information about the series, while

zip code shows zip code information.

DuckDuckGo: Enter a zip code and DuckDuckGo will return a map, zip code location, weather, real estate, and other relevant web results.

Bing: Searching a zip code in Bing returns the city/region it belongs to, maps, and local points of interest such as grocery stores, hotels, and movie theaters. If you enter an incomplete address, Bing completes it for you and displays the zip code. nine0003

How to find an area code

As with a postal code, you can use a search engine to find an area code by doing a city search. To do the opposite and find out which part of the country an area code belongs to, simply enter the area code into a search engine.

Google. To find an area code with Google, enter the name of the city and the state you are looking for, followed by the words area code ; you will usually find what you need. For international listings, search for a phrase such as The Kenya calling code is and you will receive an informative response with the numbers you will need to call this country.

Bing: Enter your city and state and you’ll likely see Google-like results that display the area code at the very top of the results. The same can be said about international codes. Searching on Bing is easier when you know some extra tips.

Wolfram Alpha: Another way to find code on the web is Wolfram Alpha, which is considered «computational intelligence». This data-driven search engine does not display results like the others mentioned on this page, but with a little digging, you can find unique city and state information that you cannot find in another search engine. nine0003

Yahoo: using Yahoo to find the area code, very similar to Google; just enter city and state name followed by area code and you will get instant results. Finding international codes is not as easy with Yahoo as it is with Google, but you can of course use Yahoo to find other sites that can provide you with this information.
