Constituents can contact their congressional representatives by email, phone, website forms or postal mail. The U.S. House of Representatives and ContactingtheCongress.org provide lists of contact information, as of 2015.
The U.S. House of Representatives website, house.gov, uses a zip code locator to identify a congressional representative and provides the available contact information. ContactingtheCongress.org displays contact information for all congressional members, searchable by street address, zip code, city or state.
Some representatives have contact forms on their individual government websites. Restrictions apply to some websites that only allow district constituents to use the form. Other representatives use social media to access concerns or answer questions through public official accounts.
