A primary tradeline is a line of credit that appears on your credit report under your name as the primary account holder. This differs from authorized user tradelines, where someone is added to another person's existing credit account. In essence, a primary tradeline represents a financial account—such as a credit card, mortgage, or auto loan—that belongs solely to you. When managed properly, primary tradelines can significantly enhance your credit score.
