The Authorized User Strategy

Becoming an authorized user (AU) on someone else's credit card is one of the fastest ways to build credit history and boost your score.

How It Works

When someone adds you as an authorized user:

  • Their account's entire history appears on YOUR credit report
  • Their on-time payments boost YOUR payment history
  • Their credit limit counts toward YOUR utilization
  • You don't need to use the card at all
  • Ideal AU Account Characteristics

  • Age: 5+ years old
  • Limit: $10,000+
  • Utilization: Under 10%
  • Payment history: 100% on-time
  • No negative marks whatsoever
  • Score Impact

    Typical AU addition can boost scores by 30-50 points within one billing cycle.

    Important Notes for Business Owners

  • Some lenders (like Fannie Mae for mortgages) may discount AU accounts
  • SBA loans typically look at primary tradelines, not AU accounts
  • Best used as a stepping stone while building your own credit history
  • CreditBooster adds positive tradelines as part of our Credit Builder plan, no need to ask family members.
