Contact Colorado’s Members of Congress

Every Coloradan has two U.S. Senators and a U.S. Representative (also known as a Congressman or Congresswoman).  Both Senators represent the state as a whole and have district offices throughout the state. Colorado has divided into seven Congressional Districts and each District has a Representative. Representatives have several offices within their districts to serve their constituents. Representative and Senators have offices in Washington DC as well.

DC offices are primarily concerned with the legislative business of Congress. District offices focus on constituent services. Contacting a district office is often the best way to identify which staff member can help you with your request whether that person is in the same office or in DC.

Methods of Contact

  • In-person meeting or invitation to an event – The legislator’s website typically has an online form to use for scheduling requests.  Making a scheduling request well in advance of a meeting or event date is recommended.
  • Postal Mail – Postal mail can be sent to the member’s office in Washington DC or a district office in Colorado. Be sure to allow a few weeks for screening and delivery of postal mail to Washington DC.
  • Phone calls – Typically, Congressional websites do not include a directory of staff. If you don’t have a contact person for the matter, you can call the general number for the office and the staffer answering the phone will help you identify the right contact person. If you are unsure where to call, it’s best to start with the district office.
  • Emails – Congressional websites typically do not include email addresses for staff either. Use the contact form to lobby on a policy issue or ask a question. Request a response and include your contact information if you would like to hear back from the member of Congress. It may take days or weeks for a response due to the high volume of email.
  • If you plan to communicate regularly by phone or email, it helps to identify the right contact person for the office, so you can call or email that person directly.
  • Social media – Although Congressional offices vary in their use of social media, nearly all of them use Facebook and Twitter regularly.
