How we ranked them

Ranked by median household income (ACS 5-year estimates, 2020–2024). The Census Bureau caps published medians at $250,000; ZIP codes at the cap are shown as $250,000+ and ordered by population. ZIP codes need at least 1,000 residents to be ranked; 133 of 136 qualify.

Which of these to mail, and why

Higher-income ZIP codes suit offers with a bigger ticket: remodeling, pools, roofing, financial planning, private schools, premium dining. A median describes the middle household, not every door, so the routes inside each ZIP still vary.

The top five ZIP codes on this list hold 57,733 households, on 123 carrier routes with 65,091 residential mailboxes. Open any of them on the route map to see each carrier route's own figures before you choose.
