Number of workers by insured status

You must be insured under the Social Security program before retirement, survivors, or disability benefits can be paid to you or your family. We consider the number of quarters of coverage you earned to determine if you are insured. You earn a quarter of coverage (QC)—also called a "credit"—for a certain amount of work covered under Social Security, but you may earn no more than 4 QCs per year. Generally you need to be fully insured to receive Social Security benefits, but other requirements may also apply.

Number of fully-insured workers

Fully Insured
To be fully insured, you need at least one QC for each calendar year after you turned 21 and the earliest of the following:

  1. the year before you attain age 62,
  2. the year before you die, or
  3. the year you become disabled.
Exceptions: If you were born before 1930, you need at least one QC for each year after 1950. Other exceptions may apply.

The minimum number of QCs needed is 6. The maximum number needed is 40. Any year (all or part of a year) that was included in a period of disability is not included in determining the number of QCs you need.

Permanently Insured
You are permanently insured if you are fully insured and you will not lose your fully-insured status when you stop working under covered employment.


  • You have earned the maximum 40 QCs, so you are permanently (and fully) insured.
  • You were born in 1949 and worked under covered employment in 1971-77, earning a total of 28 QCs. You attained age 21 in 1970. You were fully insured after you earned 6 QCs and you continued to be fully insured through 1998 (1998 less 1970 is 28). After 1998 you were no longer fully insured. Because you earned only 28 QCs, you were never permanently insured.

Number of disability-insured workers

Disability Insured
You have disability-insured status if you:

  1. have earned at least 20 QCs during the last 10 years, and
  2. are fully insured.
Exceptions apply for those under age 31 and in certain other cases. Portal to U.S. government agencies Privacy Policy  | Website Policies & Other Important Information  | Site Map
