Welcome to Washington Environmental Council Voter Education Program

Match Legislative Districts to your member lists

 

This online tool is intended for use by non profit organizations and requires password access. Membership files containing address information can be uploaded onto the server (MS Excel - "xls" file ending or plain comma separated text files - "txt" file name ending). The tool will search for Legislative District information using the geographic location of the address.

Please note that matching rates depend on data quality and usually rage from 65 - 90 %. Matching of legislative districts for records containing P.O Boxes, incomplete addresses and locations outside of Washington State will fail. Maximum allowed file size is 1MB. The estimated error rate for legislative district information with this tool is 2-5% and occurs with addresses that are close to legislative boundary lines.  If your needs require 100% accuracy - please visit the WA.gov Leg ID district finder tool.
