Credit agencies must act on the dispute within 30 days, which includes informing the entities who supplied the incorrect information of the dispute. If the investigation reveals that the information is indeed incorrect, they are required to correct it, as are the entities supplying the data. You will receive written notice of these actions and free copies of the corrected reports for your records. The CRAs are required to also provide notice copies of the corrected report to any who reviewed your report during the previous six months for creditworthiness purposes, and the previous two years for any who reviewed your report for employment purposes.
