Upon returning to the United States after the war, "Porter" operated off the east coast until she was decommissioned in June 1922. In June 1924, "Porter" was transferred to the United States Coast Guard to help enforce Prohibition as a part of the "Rum Patrol". She operated under the name USCGC "Porter" (CG-7) until 1933, when she was returned to the Navy. Later that year, the ship was renamed "DD-59" to free the name "Porter" for another destroyer. She was sold for scrap in August 1934.
