Most people don’t think about the importance of zip codes when house shopping. However, understanding how these numeric representations of cities, their neighborhoods, and their districts work can play a big part in gaining valuable information when deciding where to live.

Let’s first take a look at how zip codes work.

How Do Zip Codes Work and What do They Tell Us?

The necessity for zip codes to achieve expediency and accuracy in mailing anything in the U.S. is common knowledge. That was the U.S. Postal Service’s intent in 1963 when they first instituted use of the five-digit number at the end of any address to which a letter or package would be sent.

Finding ways to streamline delivery at that time arose from the transformation and increased use of both air and ground shipping. Twenty years later, the USPS would add an additional four digits to zip codes for even more detailed accuracy to streamline mail delivery. Use of these numbers was optional then, and still is.

The process of assigning zip codes was methodical, starting with the east coast and working westward. Each number in a zip code represents a designated area, from largest to smallest.

For example, the first number in a zip code represents a group of states. The few states in the uppermost part of New England begin with ‘0’, moving southward into Florida, whose zip codes begin with ‘3’. Numbering continues as we move north, then south, repeating all the way across to the west coast, where zip codes all begin with ‘9’.

The second number in all of Oregon’s zip codes is ‘7’. Notice on the above image how both Washington and California have multiple variations after the first number, indicating more populous areas.

The third number in the Portland area is a ‘2’, indicating an area specific to all of Portland, with ‘0’ as the fourth number, designating central Portland (and 1 or 2 for less central Portland neighborhoods). The last number is specific to each neighborhood.

Here’s how to break down a Portland zip code.

9 –West Coast
7 –Oregon
2 –Portland metro area (main mail distribution center)
0 –Central Portland (1 or 2 for neighborhoods further away from central Portland)
2 –A specific part of central Portland

Top 4 Zip Code Maps for Portland

Discerning zip code boundaries can feel like a mystery but worth your time when thinking of moving to a new area, even in your own city. If you’re new to Portland or are considering changing neighborhoods, we found some useful zip code maps to help.

1. Metro’s Regional Zip Code Map. This useful map is offered by Portland’s Metro Council for Multnomah, Washington, and Clackamas counties. You can count on this one for accurate information that extends beyond Portland proper all the way south to Canby, west to Forest Grove, and east to Troutdale. This map is also downloadable.

2. Google Earth Pro. Go to “Layers” > “More” > “Government,” and select “Postal Code Boundaries.” (This feature isn’t available for the free Google Earth.)

3. United States Postal Service Zip Code Map. Okay, this is really the USPS’ official direct mail map service, but I find it to be an incredibly detailed zip code map down to the street and house level. To try it out, simply enter in any zip code into their search bar.

4. This one is not a government map, so user beware. Data might not be entirely accurate, especially if boundaries have shifted, which happens sometimes. That said, though, the color-coded maps are a great way to get an at-a-glance view of Portland zip code areas.

Best Ways to Look up Portland Zip Codes

When you find a home you love and want to know more about the neighborhood and general area, use these three tools to start your investigation.

  • City of Portland Zip Code Lookup. This website is Multnomah-specific and lists metro area zip codes, including the city they’re in and approximate boundaries.
  • Google Maps. Google Maps is different from Google Earth Pro in that you won’t find a zip code map. But what you can do is enter a zip code, and the map will show you its boundaries. You’ll then be able to zoom in and see restaurants and other businesses, as well as parks, grocery stores, and the area’s proximity to highways.
  • United States Postal Service ZIP Code™. Use this resource to look up zip codes by: 1) address, 2) city/state, or 3) zip code to see which cities or parts of a city it covers. Found on the USPS’s own site, you can count on this one to be accurate.

Use a Portland Zip Code to Look for Real Estate

As we’ve said, zip codes can be a useful real estate tool. House hunting? Visit and search by zip code. You’ll be taken directly to an interactive map where you can zoom in and gather details about homes that spark your interest.

So what if you’ve decided to sell your home? How can this map help you? It can save you time. Instead of sorting through the entire mass of RMLS listings, search for your current zip code to see what home prices are in your area. You can also save your searches and receive updates about new sales.
