Authorized User Tradelines Explained

One of the fastest ways to build credit as a new immigrant is through authorized user tradelines. This strategy can add years of credit history to your profile almost overnight.

What Is an Authorized User?

When someone adds you as an authorized user on their credit card, the entire history of that account appears on YOUR credit report. If they've had the card for 10 years with perfect payments, you inherit that 10-year history.

How It Works

  • The primary cardholder contacts their credit card company
  • They request to add you as an authorized user
  • A card is issued in your name (you don't have to use it)
  • The account history starts appearing on your credit reports within 1-2 billing cycles
  • Your credit score can jump significantly within 30-60 days
  • Who Should Add You?

    The ideal authorized user account has:

  • Long history, 5+ years old
  • Perfect payment record, No late payments
  • Low utilization, Under 10% of the credit limit
  • High credit limit, $10,000+ is ideal
  • Important Considerations

  • You DON'T need to use the card or even have it in your possession
  • The primary cardholder is responsible for all charges
  • If the primary cardholder misses payments, it hurts YOUR score too
  • You can be removed as an authorized user at any time
  • Professional Tradeline Services

    Credit Booster offers authorized user tradeline services (called "credit boost") as part of our credit building program. We connect you with aged, high-quality tradelines to accelerate your credit building.
