You can claim Social Security retirement benefits at any time after reaching 62 years of age. If you start receiving benefits before you hit full retirement age, or FRA (currently 66 and gradually rising to 67), they will be reduced a fraction of a percent for each month before FRA that you filed.
So if a person retires at, say, age 62 and six months, the benefit is, in effect, prorated — the person is credited for waiting six months after becoming eligible.
