The authorized-user shortcut
Piggyback on a strong account to boost your file fast.
What "authorized user" means
The primary cardholder adds your name to their account. You may or may not get a physical card. Either way, the entire history of that card typically posts to your credit report within 30-45 days.
What to look for in the host account
| Criteria | Why it matters |
|---|---|
| Age 5+ years | Boosts your AAoA |
| Utilization under 10% | You inherit the low utilization |
| Perfect payment history | You inherit "0 lates in X months" |
| High limit ($5k+) | The bigger the limit, the more utilization room |
| Major issuer that reports AUs (Amex, Cap One, Discover, Chase) | Some issuers don't report AUs at all |
Typical lift
A clean AU spot on a 10-year, $10k-limit, 2%-utilization Amex can add 40-100 points to a thin file within 45 days.
Risks
- If the primary goes late, you go late too
- If the primary maxes out, your utilization spikes too
- Some lenders (FHA mortgages especially) will discount AU accounts when underwriting
Removal
Either party can remove you at any time. Once removed, most issuers retroactively delete the trade line from your report.
