ZIP codes for major Oregon cities

Salem is the state capital. Larger cities have many ZIP codes because each code follows mail delivery routes, not city limits.

These examples use real city and ZIP pairs with invented street lines, so they are safe for testing and documentation.

Tips for working with these ZIP codes

• Store ZIP codes as text, not numbers, so the format stays consistent across states with leading zeros.
• Oregon spans more than one time zone (Pacific and Mountain). Use the ZIP code or county, not the state, to decide local time.
• A quick sanity check: a valid OR ZIP code begins with one of the prefixes listed above.
• City names in addresses are post office names. A suburb may share a ZIP code and city name with a nearby larger town.
