The study looked at reports for 1,001 consumers issued by the three major agencies
-- Equifax, Experian and TransUnion. The FTC hired researchers to help consumers identify potential errors.
The study closely matches the results of a yearlong investigation by The Columbus Dispatch. The Ohio newspaper's report last year said that thousands of consumers were denied loans because of errors on their credit reports.
The FTC says the findings underline the importance of consumers checking their credit reports.
