En español | Yes. It has already increased from 65 to 66 and will be going to 67.
These changes were mandated by Congress in 1983 as part of a law that strengthened Social Security's finances. Congress cited improvements in the health of older people and increases in life expectancy as reasons for the increase. Currently, 66 is the full retirement age for people born between 1943 and 1954. Starting with people born in 1955, it will inch upward, rather than jumping right to 67. A person born in 1955 will have to be 66 and 2 months to be considered at full retirement age, while someone born in 1956 will have to be 66 and 4 months. A person born in 1960 or later will not reach full retirement age until 67.
