Zip codes are a fundamental part of the American postal system. Created by the United States Postal Service (USPS), they help organize and deliver mail accurately and efficiently. The term “ZIP” stands for “Zone Improvement Plan.” The system was introduced in 1963 to enhance the efficiency of mail sorting and delivery.
Each zip code in the U.S. points to a specific geographic region. These codes simplify the delivery of letters and packages. They also play a role in demographics, marketing, navigation, and emergency services. Zip codes can reveal much about a place—its size, location, and sometimes even its purpose.
Understanding the Format of a Zip Code
A standard U.S. zip code has five digits. The first digit represents a group of U.S. states. The second and third digits point to a region within that group. The final two digits identify a more specific area, such as a town or part of a city.
For example, zip code 90210 is well-known for Beverly Hills, California. Likewise, zip code 10055 has its own special meaning and use. Let’s explore what makes this zip code unique.
Where is Zip Code 10055 Located?
Zip code 10055 is located in New York, NY. It is part of Manhattan, the economic and cultural heart of New York City. Specifically, 10055 is known as a unique zip code.
A unique zip code is not assigned to a neighborhood or general population. Instead, it is reserved for a specific organization or building. In the case of 10055, this code is primarily used for:
- General Electric Company Headquarters
- Located at 30 Rockefeller Plaza (also known as the GE Building)
This location is iconic. It stands tall in the heart of Midtown Manhattan, surrounded by major businesses and famous landmarks like Radio City Music Hall and Times Square.
Type and Purpose of Zip Code 10055
As mentioned, zip code 10055 is a unique zip code. USPS assigns unique zip codes to certain organizations, large corporations, and government entities. These codes help streamline mail delivery by directing items to high-volume addresses.
The main purpose of 10055 is to support fast and accurate delivery to a high-traffic business location. Instead of sorting mail through the broader Manhattan system, USPS sends it directly to this address.
Other Examples of Unique Zip Codes
10055 is not alone. There are many other unique zip codes across the U.S., such as:
- 20500 – The White House, Washington, D.C.
- 10199 – Internal Revenue Service (IRS), New York, NY
- 94105 – Salesforce Tower, San Francisco, CA
These codes are vital for efficient mail distribution at a large scale.
Geographic Coverage of 10055
Unlike standard zip codes, 10055 does not cover a wide geographic area. It refers to one address only—30 Rockefeller Plaza. This building has multiple floors and tenants, but the code is linked to the main business occupant.
Because of its unique status, 10055 does not apply to residential buildings or surrounding streets. Regular mail users in that neighborhood use nearby standard zip codes such as 10020 or 10036.
Businesses and Institutions Using Zip Code 10055
General Electric (GE) is the most well-known organization linked to this zip code. Although GE has moved some operations, 10055 remains tied to its former headquarters. It is a legacy code and part of USPS’s consistent address system.
In addition to GE, other businesses operating from 30 Rockefeller Plaza may use this zip code for mailing purposes. However, it remains a specialized designation, not used by the general public or for residential use.

The Role of USPS in Managing Unique Zip Codes

Once assigned, these zip codes are rarely changed. They form part of USPS’s infrastructure and mapping system. Businesses that qualify must demonstrate ongoing need for such a service.
