The Authorized User Strategy Nobody Talks About

Adding someone as an authorized user on your credit card costs you almost nothing and can add 20 to 50 points to their credit score in 30 days. This is one of the most efficient credit-building tools available, and almost nobody in personal finance talks about it clearly.

How Authorized Users Work

When you add someone as an authorized user on your credit card, the card's history — including the account age, credit limit, and payment history — appears on their credit report. If your card is old, has a high limit, and has been paid on time, that history transfers to them.

The authorized user doesn't need to use the card. They don't even need to have the card in their possession. You can add them, request the card, put it in a drawer, and the credit-building effect still occurs.

The Mechanics

Not all credit card issuers report authorized user accounts to all three bureaus. Chase, Amex, Capital One, and Discover all report to Experian, Equifax, and TransUnion. Citi and others may vary. For maximum effect, add the authorized user to a Chase or Amex card.

The account typically appears on their report within 30 to 45 days of being added.

The Risk Assessment

You are not liable for anything the authorized user charges. Wait — that needs clarification. You, the primary cardholder, are responsible for all charges on the card, including those made by the authorized user. But you control the card. You can remove the authorized user at any time. You can hold the physical card and never give it to them.

The authorized user cannot make account changes, cannot call to increase the limit, and cannot do anything that affects your account standing. They can only make purchases if they have the physical card.

Who to Add

This strategy works best for adult children trying to establish credit, spouses with thin credit files, or anyone you trust financially who needs a credit history boost.

Marcus's sister used this strategy when she moved back from abroad and had no US credit history. We added her to the Chase Sapphire Preferred for three months. Her credit score went from 0 (no US file) to 720. She then applied for her own card and was approved immediately.

The Card to Use

The Chase Sapphire Preferred is good for this strategy: old account age (for those who opened it years ago), high credit limit, and Chase reports to all three bureaus. The authorized user card earns points on the primary account — you both benefit from their spending.

This is a free credit-building tool. The only reason more people don't use it is that nobody explains it this plainly. Now you know.
