Frequently Asked Questions

What is a ZCTA (Zip Code Tabulation Area)?

US ZIP codes were created by the USPS for mail delivery. This means that they don't always cover a continuous geographical area. What's convenient for delivery purposes (e.g. delivering on one side of the street except for large businesses) doesn't always lend itself to mapping or statistics. Since zip codes are often used for these purposes, the US Census Bureau calculates the approximate boundaries of zip code areas. These areas are called Zip Code Tabulation Areas.

Are all zip codes ZCTAs (Zip Code Tabulation Areas)?

No. Some zip codes are for PO boxes only, unique to an organization, or used by the military. Such zip codes are not areas and therefore are not represented by ZCTAs. When possible, our database uses parent_zcta to let you know if a zip code resides within an established ZCTA. This allows you to use the ZCTA as a proxy for additional information.

Is the Basic (free) version sufficient for my needs?

The Basic (free) database will meet many users needs. You may want to purchase the Pro or Comprehensive versions if:

You need data for infrequently-used zip codes that are unique to businesses, used for P.O. boxes or reserved for the military.
You need demographic data such as age, race, education or income.
You don't want to attribute your use of our data on a public-facing website.

How are latitude and longitude calculated?

We've used GIS software to calculate the centroid for every ZIP code categorized as a ZCTA. A centroid is the average position of all of the points in a shape. This is best way to convert an area into a point. For zip codes that represent discrete points, we've used authoritative sources such as the National Weather Service to geocode them into latitude and longitude.

Why don't latitude and longitude coordinates exist for some zip codes?

Some zip codes, such as those used by the military, do not represent a discrete point or a ZCTA area. In these cases, it's not possible to convert a zip code to a geographical point.

Am I allowed to redistribute the database if I purchase a paid license?

No. You are not allowed to sell the database or make it publicly available. However, you can make copies and backups of the data. You are also allowed to query the database to power publicly facing applications such as a store locator. To learn more, read the full license terms.

How often do you release updates?

It depends. We frequently monitor the USPS for updates to zip codes. If there are any changes, we will release a new version.

Why should I trust this data?

This database was aggregated from authoritative sources and carefully processed by SimpleMaps. We've been developing and selling interactive maps to Fortune 500 companies and prominent international organizations for over 14 years. Over this time, we've learned a lot about geographic data. To get a sense of the expertise and support we offer, check out some of the testimonials from our happy customers.

If I use the free database, what type of attribution is required?

If you use the Basic (free) database, you must link back to this page:
https://simplemaps.com/data/us-zips
from a public webpage where you are using the data. If you want to use the data internally, you must link back to this page from your firm's website on a page that can be easily found though links on the root domain. The link must be clearly visible to the human eye.

Why do other databases contain more zip codes?

Unlike other databases, we only include one entry per zip code and we only include active USPS zip codes and ZCTAs. Our goal is to create an accurate database that is easy to use, not artificially inflate the size of our database.

How do I calculate the distance between two zip codes?

We've published free formulas in popular programming languages. Check them out.

How recent are the demographic variables such as income_household_median?

Almost all of the demographic variables come from the 2022 American Community Survey (5-year estimate) which is run by the United States Census Bureau. A few fields: farmer, self_employed and charitable_givers come from 2016 IRS data.

How come some demographic variables are blank (empty strings) for some zip codes?

For privacy reasons, the Census Bureau and IRS will only provide zip code level data if the zip code is large enough to protect resident privacy. So, for smaller zip codes some variables may not be available.

Is it possible to get the age fields disaggregated into 5-year buckets?

Yes, this is available for no additional charge for comprehensive license holders. Please contact us for help.

Has your database been updated with results from the 2020 Census?

Yes, all latitude and longitude coordinates for ZCTAs (and geographic relationships) are now based on ZCTA shapes from the 2020 Census. We're also now using the 2022 American Community Survey (5-year estimate) for demographic data.
