Barney reported to Division 19, Atlantic Fleet, and engaged in fleet exercises and maneuvers along the eat coast until 30 June 1922, when she went out of commission at Philadelphia. Recommissioned 1 May 1930, Barney operated with Destroyer Squadron, Scouting Force, on the east coast and in the Caribbean until transiting the Panama Canal in February 1932 to participate in fleet problems off San Francisco. Remaining on the west coast, she operated for a time in reduced commission with Rotating Destroyer Squadron 20, Scouting force. In 1935 she cruised with Destroyer Division 3 to Alaska, thence to Honolulu, and later to the Puget Sound area for fleet problems.
Returning to the east coast she conducted cruises with the 10th Training Squadron until November 1936 when she was placed out of commission. Recommissioned 4 October 1939, she served on patrol duty with the 66th Division, Atlantic Squadron, and during the following year with the Inshore Patrol, 15th Naval District Defense Force.
Between December 1941 and November 1943 Barney was assigned to the Caribbean area, escorting convoys between Trinidad, British West Indies; and Guantanamo Bay, Cuba. On 18 September 1942 she had a collision with Greer (DD-145), resulting in severe damage and the loss of two of her crew by drowning. Both ships returned to Willemstad, Curaçao, Netherlands West Indies, where temporary repairs were made and then Barney departed for Charleston Navy Yard. Permanent repairs completed in December 1942, she returned to the Caribbean.
