ZIP Code Assignments and Change Requests
A Chapter territory consists of postal zip codes that are assigned by National in consultation with the Chapter and its State Office or the Chapter Services Office if there is no State Office. Territories may vary in size, but the designated territory should be of a size that members find comfortable to travel to meetings and events, a distance usually from 15 to 30 miles (or 45 minutes maximum driving time). Actual size will depend upon the area requested by those forming the Chapter and is finalized at the discretion of the State Director or Chapter Services Office responsible for helping to create the Chapter. If you would like to review your Chapter’s list of ZIP codes and/or a map of your territory, please contact Chapter Services (please keep in mind that PO Box ZIP codes will not show up on the map, so you'll need to get a list of those from your post office to make sure you aren't missing any ZIPs within the geographic boundaries of your territory). Chapters are encouraged to review this list at least once after every US Census, because the Postal Service sometimes adds ZIP codes, and to contact Chapter Services if changes are needed.
Membership and Recruitment Outside of a Chapter's Territory
Member recruits that do not live within your Chapter's territory--either in another Chapter's territory or in an unclaimed territory that is not feasible to add to your Chapter's territory--may be added to the Chapter's roster as long as the proper coding is used on the membership form. Likewise, current Audubon members who live outside the Chapter's territory but would like to be part of the Chapter can contact Member Services and request to be "hard-coded" to the Chapter of their choice (must provide the 3-digit Chapter code).
