How do you properly address an envelope and letter to a state representative?

To address an envelope to a state representative, place their name on the first line, followed by their title (e.g., "The Honorable [Full Name]"). On the next line, include the state representative's office address, typically formatted as "State Capitol, [Street Address], [City], [State] [ZIP Code]." In the letter, start with a formal salutation like "Dear Representative [Last Name]" to maintain professionalism.
