Six girls who had been prostituted, some for years, were rescued last week in Pierce and King counties during a sweep coordinated with a nationwide campaign.
Authorities also arrested seven people on suspicion of promoting commercial sexual abuse of a minor. Their names were not released.
All of the victims were offered services like job training, housing, counseling and medical and education assistance, according to the FBI.
The sweeps took place Thursday to Saturday in Tacoma, Lakewood, Auburn, Seattle, Bellevue and other areas in King County in coordination with the national effort, Operation Cross Country VI.
Locally, three Innocence Lost task forces helped recover the victims by contacting them through undercover agents and canvassing areas where prostitution is known to happen.
