I sold authorized user tradelines on my own credit cards, and one of the questions that kept landing in my inbox is about auto primary tradelines — usually from someone who’s been told they need one on their report before a car purchase will go through. An auto primary tradeline is an auto loan reported on your credit file with you as the primary borrower: your name on the loan, your payment history, your responsibility. That’s the simple part. The complicated part is the market that has grown around the phrase, because a lot of people typing it into Google aren’t looking for a definition — they’re looking to buy one. And that’s where I owe you a straight answer, even if it costs me a sale (it usually doesn’t — more on that below).
