How we ranked them

Ranked by the change in ACS population estimates between the 2015–2019 and 2020–2024 releases. Both are 5-year averages, and ZIP code areas were redrawn for 2020, so a large change can partly reflect a boundary change. Both periods must have at least 1,000 residents. ZIP codes need at least 1,000 residents to be ranked; 26 of 26 qualify.

Which of these to mail, and why

Growing ZIP codes add households every year, which means new homes, new routes and customers without a go-to provider yet. Check the route map: new subdivisions can appear as new carrier routes.

The top five ZIP codes on this list hold 36,800 households, on 50 carrier routes with 34,940 residential mailboxes. Open any of them on the route map to see each carrier route's own figures before you choose.
