Mailing Destinations

Where the card can land.

Greater St. Louis, one neighborhood at a time. A card is up to 5,000 homes on selected USPS Every Door Direct Mail routes — not every ZIP in a region on day one.

West County is the first edition we're filling. The other six areas on this page are the rest of the metro we built FridgeSaver to cover. They are not live cards yet.

West, South, North, and Mid County are local names inside St. Louis County — they are not official county lines. Some cities sit on a highway and get claimed by more than one label. ZIP codes can straddle a city limit. Treat the lists as a guide, not a survey plat.

Seven areas. One map.
