A car purchase can take up to 60 days to show up on your credit report. After the dealer reports your purchase to the credit bureau, it typically takes 30 days for the information to appear. However, it can sometimes take longer, depending on the credit bureau and the dealership's reporting schedule.
You can check your credit report to see if your new car purchase has been added by visiting AnnualCreditReport.com. You can request one free credit report from each of the three major credit bureaus (Experian, Equifax, and TransUnion) every year.
