Preguntas Frecuentes

What is an authorized user tradeline exactly?

It's you as an authorized user on a stranger's prime credit card, piggybacking their history onto your report for a quick score bump—no card or payments needed.

How much does an authorized user credit boost really cost?

Basic ones run $100-500; premium (high-limit, aged) hit $1,000-2,000 for 1-3 months. Free from family, but less control.

Are authorized user tradelines legal in 2026?

Yes, protected by ECOA—no federal ban. Lenders frown and may ignore them, but buying spots isn't illegal.

How long do tradelines stay on my credit report?

They post in 30-60 days, last as long as you're added (months), then linger 60 days post-removal. Not forever.

Can piggybacking credit hurt my score?

Absolutely—if primary messes up, gets removed, or lenders flag it. Drops of 50+ points happen.

What's better than buying tradelines for credit repair?

Primary accounts like secured cards or builder loans you control—slower but permanent, no flags. Pair with apps like Credit Booster AI for errors.
