How we ranked them

Ranked by median value of owner-occupied homes as reported by owners (ACS 5-year estimates, 2020–2024). Published medians are capped at $2,000,000. ZIP codes need at least 1,000 residents to be ranked; 22 of 24 qualify.

Which of these to mail, and why

Home value tracks what owners spend on the house itself: renovations, landscaping, pest control, security, interior design. Pair it with the homeowner share so the mailer reaches owners, not tenants.

The top five ZIP codes on this list hold 74,729 households, on 107 carrier routes with 92,908 residential mailboxes. Open any of them on the route map to see each carrier route's own figures before you choose.
