The Greek coverage certification is used to assign foreign (F) quarters of coverage
to the U.S. earnings record.
Greece credits periods of coverage on a daily basis. Three hundred days of Greek coverage
equals four foreign quarters of coverage (FQC). Seventy-five days of Greek coverage
equals one FQC.
All periods of coverage certified by Greece are creditable unless they are already
credited as U.S. quarters of coverage.
There is no minimum amount of Greek coverage which must be earned before the U.S.
can use it.
