How to Convert States to Zipcodes

How to Convert States to Zipcodes Using Python Programming Language

Python is an open-source programming language that is widely used in various data applications such as data analysis, machine learning, and web development. It is also used in the automation of certain processes that include data manipulation, file management, and many others. In this article, we shall discuss how to convert states to zip codes using Python programming language.

Understanding Zip Codes

Zip codes are unique identifiers that are assigned to different regions in the US by the United States Postal Service (USPS). They are five-digit codes that are used in mail deliveries to help the USPS deliver the mail to the correct location. Zip codes make it easier for the USPS to sort and deliver mail efficiently.

Understanding States

A state is a defined territory in a country that is governed by a particular constitution and a particular set of laws. In the US, there are 50 states, each with its unique identity.

Converting States to Zip Codes

To convert states to zip codes using Python programming language, we shall use a Python library called USZipCode. USZipCode is a Python library that provides zip code information for the entire United States. To use the USZipCode library, you will first need to install it in your Python environment. You can install it by running the following command in your terminal:

pip install USZipCode

Once you have installed the USZipCode library, you can now proceed to convert states to zip codes using Python. The following Python code will help you to convert states to zip codes:

from USZipCode import SearchEngine

search = SearchEngine()

# Convert State to Zip Code
zipcode = search.by_state(‘New York’)


In the above Python code, we imported the SearchEngine class from the USZipCode library. We then created a new instance of the SearchEngine class called search.

We then used the by_state() method of the search object to convert a state to a zip code. In this case, we converted the state ‘New York’ to a zip code.

The output of the above Python code will be a list of zip codes for the given state. The USZipCode library uses a list to account for the cases where there are multiple zip codes for a particular state.


In conclusion, converting states to zip codes using Python programming language is easy using the USZipCode library. By using the SearchEngine class in the USZipCode library, we can easily convert a state into a list of zip codes. With this knowledge, you can easily extend it to meet your specific use case in your Python applications.
