Several boundary notes matter here. Lake Oswego and Milwaukie are Clackamas County cities whose limits cross the line into Multnomah by only a few blocks, so their citywide populations are not counted above. West Haven-Sylvan straddles the Washington County line north of US 26, and the Cedar Mill CDP likewise sits almost entirely in Washington County with a small Multnomah edge. Older versions of this page listed dozens of places such as Alameda, Sellwood, St. Johns, Kenton, Montavilla and Linnton as separate towns — all of them are neighborhoods of Portland, not municipalities. St. Johns and Linnton were annexed by Portland in 1915.<\/p>\n

ZIP Codes<\/h2>\n

Portland alone uses the 972xx block, running from 97201 through 97299 (including PO box and unique-use codes), so this list covers the county’s codes outside the Portland core.<\/p>\n
