Don't buy so called "unlimited" package on Carfax, cause it's not unlimited at all. I paid for this package and was able to run only 5 reports by VIN number! You can run multiple reports by license number but I wasn't able to check vehicles using license number. The price for one Carfax report is too high, and I was planning to check more than 20 cars and I thought that unlimited package presupposes that I can get as many reports as I need and not just 5 of them! Do not repeat my mistake if you don't want to waste your money.
