How we ranked them

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 29,240 households, on 82 carrier routes with 31,530 residential mailboxes. Open any of them on the route map to see each carrier route's own figures before you choose.
