How to play

Guess today’s ZIP from distance- and place-style clues. It is a US5 exclusive: the same ZIP identifiers that power Places pages, presented as a daily geography puzzle instead of a data table.

ZIP codes vs places on a map

ZIP Codes are USPS delivery routes, not census polygons. On US5 we still treat a five-digit ZIP as a practical place key — linking mail geography to cost, salary, and demographic snapshots on `/zip/{code}` pages.

Daily ZIP Guess trains you to think in that five-digit space: coastal vs inland, metro fame (90210), and how a code can sit next to a very different neighbor.

After you guess, open the real ZIP page

A correct (or revealed) ZIP is a doorway into US5 Cost and Places — rent signals, wages, and methodology — not just trivia. Use the quiz to discover codes, then dig into the data.

Zone Improvement Plan geography: East-to-West routing

The U.S. Postal Service introduced the 5-digit ZIP code system in 1963, structured on a strict geographic gradient from East to West. Digit 0 represents New England and Puerto Rico, moving through 1 (New York/Pennsylvania), 2 (Mid-Atlantic), across the Midwest (4–6), through the Mountain West (7–8), reaching 9 on the Pacific Coast and Alaska/Hawaii.

Daily ZIP Guess trains you to decode these spatial gradients: a single starting digit immediately eliminates 80% of the country, while the next two digits pinpoint the regional Sectional Center Facility (SCF).

Frequently asked questions

Are these real deliverable ZIPs?
Yes — curated, well-known codes used for education. Always verify unusual codes on an official USPS tool before mailing.
How is ZIP Guess different from ZIP Code Quiz?
ZIP Guess is a once-a-day challenge with progressive clues. ZIP Code Quiz is a multi-round practice set you can replay anytime.
What do the first digits in a ZIP code represent?
The first digit represents a broad group of U.S. states (from 0 in New England to 9 on the West Coast). The second and third digits identify the regional central postal sorting facility (SCF), and the final two digits specify the local delivery post office or carrier station.
Can a single ZIP code span across multiple towns or counties?
Yes. Because ZIP codes are designed for mail delivery logistics rather than political borders, many rural and suburban ZIP codes cross municipal and even county boundaries.
Is this official government data?
No. Games are educational practice tools. For decision data — cost of living, salary, ZIP demographics — use US5 Places, Cost, and Money pages, which cite Census / HUD-style sources.
