Famous ZIP Codes in the United States: What a ZIP Code Is and Why It Exists

What Is a ZIP Code?

A ZIP Code is a postal code used in the United States to identify specific geographic delivery areas. The term ZIP stands for Zone Improvement Plan, a system introduced by the United States Postal Service (USPS) in 1963 to improve the speed and accuracy of mail delivery.

A standard ZIP Code contains five digits:

• The first digit represents a group of U.S. states or a large region.
• The next two digits identify a sectional center facility (a mail sorting hub).
• The last two digits represent a local delivery area.

Later, the ZIP+4 system was introduced to provide even more precise delivery locations, such as specific buildings or city blocks.

Why ZIP Codes Were Created

Before ZIP Codes, mail sorting was largely manual and time-consuming. As the U.S. population and mail volume grew—especially after World War II—the postal system needed a way to automate and standardize delivery routes.

ZIP Codes were created to:

• Speed up mail processing
• Reduce delivery errors
• Enable automated sorting
• Improve logistics planning

Today, ZIP Codes are used for far more than mail delivery. Businesses use them for:

Market research and demographic analysis

• Targeted marketing and advertising
• Territory planning and logistics
• Insurance and risk modeling
• Real estate analysis

Because ZIP Codes are tied to geography and population patterns, they have become one of the most widely used geographic identifiers in the United States.

How Businesses Use ZIP Codes Today

ZIP Codes have evolved into a critical tool for:

• Location intelligence
• Customer segmentation
• Territory planning
• Delivery optimization
• Demographic analysis

For marketers and data professionals, ZIP Codes provide a powerful way to understand geographic patterns in income, population, and consumer behavior.

For example, let's compare AGI (Adjusted Gross Income) returns between these zip codes and find out how each is performing. Below is a code excerpt, you can download the full Python code from our Github Repository. The full code does the following:

• Uses a list of the most famous zip codes in this blog article.
• Leverages the end point /zipc/v1/zipcodes/{zipcode}/soi?year=2022 to get return statistics for each zip code.
• Aggregates the data by zip code and sorts the result in descending order.
• Plots a bar graph with each zip code sorted from top income to lowest income in the list.

def get_agi_total_single_year(zipcode, year):
    url = f"{BASE_URL}/{zipcode}/soi?year={year}"
    response = requests.get(url, headers=headers)

    if response.status_code != 200:
        print(f"Error for {zipcode}: {response.status_code}")
        return None

    data = response.json().get("data", [])
    df = pd.DataFrame(data)

    if df.empty:
        return None

    # Ensure numeric
    df["agiGroupId"] = pd.to_numeric(df["agiGroupId"], errors="coerce")
    df["adjustedGrossIncome"] = pd.to_numeric(df["adjustedGrossIncome"], errors="coerce")

    # Filter AGI groups 1–6
    df = df[df["agiGroupId"].between(1, 6)]

    total_agi = df["adjustedGrossIncome"].sum()

    return total_agi

When running this python code you should get the following graph:
