Consumers need to be extra vigilant about checking for any errors on their credit reports, according to the Federal Trade Commission. One in four Americans report they’ve found an error on their credit report, according to a study conducted by the FTC, which analyzed 1,001 consumers’ credit reports from the three major agencies, Equifax, Experian, and TransUnion. Researchers helped the consumers spot potential errors on their reports. Five percent of the consumers found such large errors on their report that they could have gotten stuck paying more for mortgages or other financial products, if they hadn’t taken steps to correct it before applying, according to the study.
