Oregon ZIP Codes

ZIP Codes 97000-97999 are all in Oregon. The numbering scheme appears to be:

• 970xx: Portland suburbs, (but excluding Portland) plus the area to Sherman County
• 971xx: NW Oregon, including north coast
• 972xx: Portland and adjacent communities in Clackamas and Washington counties
• 973xx: Salem area: central coast to Cascade mountains
• 974xx: Eugene area: south central coast to Cascade mountains
• 975xx: Medford area (Jackson and Josephine counties)
• 976xx: Klamath Falls area (Klamath and Lake counties)
• 977xx: Central Oregon (primarily Crook, Deschutes, Harney, Jefferson counties)
• 978xx: Pendleton area (Baker, Gilliam, Grant, Morrow, Umatilla, Union, Wallowa, Wheeler counties)
• 979xx: SE Oregon: Malheur County plus other immediate communities (Served by Boise)

Within each 3-digit designation, numbers are issued in the following manner: The main post office is given the -01 ZIP Code (Salem 97301). Some space may or may not be reserved (-02 to -09, for instance). The rest of the communities in the area are then alphabetized and issued numbers in that order. Generally you will see the A- communities at the top of the list and the Z- communities at the bottom. In some cases, post office names may be out of order. One reason could be that a rural post office is served by another larger one as in the case of the closed out McCoy (97339) having been served by Dallas (97338). 970-, 971-, and 979- do not follow the -01 nomenclature. In these cases Portland is the -01 for 970- and 971-, and Boise, Idaho is the -01 for 979-. Portland is also the -01 for Washington's 986-.

ZIP Codes mostly follow county lines. Cases where they do not would include a post office and ZIP Code closing out to the most convenient post office across a county line. Gilliam County has only two post offices, (Arlington and Condon), the fewest of any county in Oregon. However, Mayville in Gilliam County closed down to Fossil in Wheeler County, thereby creating a small area of Gilliam county that is served by a third post office outside of the county. Crook County is unique in that all four of the county's post offices and ZIP Codes are in sequential order (Paulina, Post, Powell Butte, Prineville; 97751, -52, -53, -54).

In the list by ZIP Codes, multiple names separated by commas means either multiple communities and/or post offices are in the same ZIP Code, or the United States Postal Service recognizes several names for the area. In most cases, the first name is accepted by the USPS and the remaining entries are communities that are served by that zip code. Many secondary entries never had their own zip code or post office.

Italicized entries are defunct ZIP Codes that are no longer recognized. Most of these communities' postal services have been absorbed by a neighboring community. Some of these ZIP Codes have been re-issued (such as 97339 from McCoy to Corvallis). Others are still used, but are issued from a single post office. Such a case is five zip codes served by Burns: Burns, Fields, Princeton, Diamond and Frenchglen (97720, 97710, 97721, 97722 and 97736). Burns also took over Lawen (97740) upon its closure.
