ZIP Code Data Editors

Background

The PlainZIP compiles, verifies, and contextualizes ZIP code-level data from the U.S. Census Bureau American Community Survey and ZIP Code Business Patterns. We pair raw federal data with plain-language explanation so the typical visitor, a homebuyer, renter, journalist, researcher, can read a ZIP code's demographics without prior census expertise. The team does not accept payment, sponsorship, or promoted placement from entities it covers.

According to this portal's Publishing Organization, editorial profiles on this site were last reviewed in August 2026 against the source rules on our methodology page. Responsibility for every published extract, including tables above 1,000 rows when the corpus is that large, sits with the publisher named here, not with a synthetic collective.

How to use this site

PlainZIP publishes reference material, data-driven pages, and explanatory tools. Use the source information, assumptions, limitations, and methodology shown on the individual page to decide whether it fits your situation.

Published information can summarize source data or provide an estimate; it is not professional financial, medical, legal, or engineering advice. For an important decision, compare the relevant page with a primary source or a qualified professional.

How information is presented

Pages that present data or estimates identify the available source, method, and material limitations. Results can differ from real-world outcomes because inputs, rules, rates, rounding, data coverage, and individual circumstances vary.

The methodology page explains the site-level approach and limitations. Check the source information on the page you are using rather than treating site-wide wording as a substitute for the current source.
