How do you address a letter to a Supreme Court judge?

In a letter addressed to the chief justice of the U.S. Supreme Court, the salutation reads "Dear Chief Justice" followed by a colon. For a letter to an associate justice, the salutation reads "Dear Justice" followed by the justice's last name and a colon.

When writing a letter to the chief justice of the U.S. Supreme Court, use the following address: The Chief Justice of the U.S. Supreme Court, One First Street NE, Washington, D.C. 20543. When writing a letter to an associate justice of the U.S. Supreme Court, use the same address. If there are two or more associate justices with the same last name, include the first name of the justice as well.
