Telephoning a Member of Congress

It's easy to contact your federal legislators by telephone. Call the capitol operator directly at 202/224-3121. Once you are connected to the capitol operator, ask for your senator or representative by name. You will then be connected directly to the member’s office. Identify yourself as a constituent, and deliver your message. Make sure to leave your name and address to get a response. 

Writing to a Member of Congress

Faxes and emails are the recommended forms of communication with a congressional office. Sending a letter via post is greatly discouraged because of time delays associated with security procedures.

Composing Your Letter

Your purpose for writing should be stated in the first paragraph of the letter. If the letter pertains to a specific piece of legislation, identify it accordingly, by bill number if possible. Be courteous and to the point. Include key information, using examples to support your position. Address only one issue in each letter. Try to keep the letter to one page.
