Ozipedia The ZIP Code Encyclopedia
Ozipedia The ZIP Code Encyclopedia

Every ZIP code, explained by its data.

Ozipedia is a reference work, not a listings site. Each entry describes one ZIP code — who lives there, what it costs, what the hazards are, how the schools and the streets measure up — and every figure names the agency it came from and the year it describes.

10 ZIP codes published · wave 1 Coverage expands in waves. This is what is published today, not a plan.

Where the numbers come from

Every entry is assembled from public data. Ozipedia adds the joining, the comparison and a small number of its own scores — and those scores each link to the method that produced them.

Where a source has nothing for a ZIP code, that section is simply absent. Ozipedia does not print "no data available" and it does not fill a gap with an estimate. Read how Ozipedia is made for vintages, methods and the corrections policy.

Ozipedia is the reference. OurZip is the live view.

Ozipedia entries are written, dated and stable — they describe a place rather than report on it minute to minute. For what is happening in a ZIP code right now — current alerts, events, local updates and an interactive map — OurZip is the companion tool, from the same team.
