There is no definite answer to this question. When certain information appears on your credit report depends when your lender reports to the credit bureau. If the lender does not report through the credit bureau at all the information might never appear on your credit report. If you are waiting for some information to get updated on your credit report on the basis of a dispute letter has been passed in your favor then you should typically wait for a maximum of two billing cycles to see if the information gets updated not. This means that the date is likely to appear anywhere from 0 to 60 days after the credit bureaus investigation has come back in the favor of your claim.
