In order to ensure that all of your faxes go to your representative, please make sure that you have the four digit extension of your zip code in your user information. You can find this field and make corrections after logging in to the site. If you require assistance finding your four digit extension code, go to the United State Postal Service website found here: http://zip4.usps.com/zip4/welcome.jsp.
If the wrong representative is still listed after following the above steps, please submit a help request with which congressman is being displayed and which should be showing.
