FAQ -Do all authorized user tradelines show up on credit reports

Most credit cards allow you to add someone as an authorized user and most Visa/MC accounts will actually report to the credit bureaus (other revolving accounts like store credit cards do not report), Of these, only a few of them actually report to the credit bureaus on a consistent basis. For example many of the cards that report take an average of 3-6 months before they begin reporting, may only report to one credit bureau, or switch bureaus they are reporting to periodically.

The reasons most lenders don’t report on a regular consistent basis is to help avoid their card being used to artificially increase someone’s credit report.
