If you do not know who your congressional representrative is, you will first need to know your 9-digit zip code. If you are not sure of the last 4 digits of your zip, go to http://zip4.usps.com/zip4/welcome.jsp and type in your address and 5 digit code, click “submit” and the USPS will tell you your 9 digit zip. Then go to http://www.house.gov/writerep/ and find out who your congressperson is.
