📌 Notes

• The precise ranking can vary slightly depending on the source and year of the underlying data; different datasets (e.g., IRS adjusted gross income vs. census median income) may list slightly different ZIP codes.

• ZIP codes with very small populations (e.g., under ~100 residents) often appear extremely high in income rankings due to small sample sizes — but the list above focuses on more sizable communities when possible.
