NOTE - these city names may not correspond with the city limits or other jurisdiction boundaries of incorporated cities. There are other acceptable city names listed that may be used for mailing addresses for some ZIP Codes. There are also other city names to avoid using for mailing addresses.

It was compiled by checking all numbers from 97000 - 97999 with the ZIP Code Lookup tool.</p><p></p><div><p>Most Standard and some PO Box Only ZIP Codes may also be listed as Census ZIP Code Tabulation Areas (ZTCA). NOTE - The ZTCA is only an approximation of a ZIP Code area based on the predominate ZIP Code of all housing units in each Census block. ZIP Codes actually follow lines of travel along letter carrier routes and are not polygons as shown by the ZTCA.</p></div></div>

<p>美国邮政服务区域改进计划（ZIP）代码在美国范围内被广泛使用，旨在提升邮件投递效率。俄勒冈州拥有479个独特的五位数ZIP代码，均以97开头。所有ZIP代码均由美国邮政服务独家分配和管理。ZIP代码主要分为三大类别：1）标准型，2）仅邮编箱，3）大型商业和政府客户的专有型。</p><div></div><div><p>美国邮政服务为每个ZIP代码指定了一个首选的城市名称。注意——这些城市名称可能并不与城市的行政边界或其他法人管辖区域的界限相吻合。对于某些ZIP代码，还有其他可接受的城镇名称，可用于邮寄地址。同时，也有一些城镇名称应避免用于邮寄地址。为验证首选的、可接受的或应避免的城镇名称，请使用美国邮政服务的此工具输入ZIP代码——https://tools.usps.com/zip-code-lookup.htm?citybyzipcode</p><p></p><p>此工具并非美国邮政服务的产品。它通过对97000至97999的所有数字进行ZIP代码查询工具的检查而编制而成。</p><p></p><div><p>大多数标准型以及一些仅邮编箱的ZIP代码也可能被列为人口普查ZIP代码统计区域（ZTCA）。注意——ZTCA仅是基于每个普查块中所有住宅单元的占主导地位的ZIP代码的一个ZIP代码区域的近似。ZIP代码实际上遵循邮递员的旅行路线，而不是如ZTCA所示的多边形。</p></div></div>
