Tradeline: Definition & Example

What Is a Tradeline?
A tradeline is an individual credit account listed on a credit report, such as a credit card, auto loan, mortgage, or student loan, along with its balance, limit, and payment history.
What does tradeline mean?
Each tradeline shows the creditor, account type, open date, credit limit or original loan amount, current balance, payment status, and a month-by-month payment history. Together, tradelines make up most of a credit report.
Lenders often look at the number and age of tradelines. Some mortgage programs require a minimum number of established tradelines, such as three accounts open for at least 12 months.
Being added as an authorized user on someone else’s long-standing credit card adds that tradeline to your report. Some companies sell authorized-user tradelines, which lenders may discount or disregard.
Tradeline example
A borrower’s credit report lists four tradelines: a credit card opened in 2017 with a $6,000 limit, a paid-off car loan, a student loan in good standing, and a store card opened last year. All show no late payments.
