Estrategia de usuario autorizado: sube tu puntaje rápido

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.
