How to Become an Authorized User: The Free Route and the Paid Route, Compared

To become an authorized user, the primary cardholder adds you to their credit card account through the card issuer, usually online or by phone. You can ask someone you trust to add you for free, or pay a tradeline company to add you to a stranger's seasoned card for a set period.

What being an authorized user means

You're added to someone else's credit card. That account's age and payment history may report on your credit file. You aren't responsible for the debt, and you don't own the account. That's the difference from a joint account or a co-signer: see Authorized user vs. joint account vs. co-signer.

The catch: the card's history shows on your file, good and bad. So the card you join matters more than the route you take.

Route 1: Ask someone you trust

This is the classic route: a parent adds a teenager, or a partner adds a partner.

1. Pick the right card. Look for a card that has been open for years, has no missed payments, and carries a low balance compared with its limit.
2. Ask the issuer whether the card reports authorized users. Many major issuers report authorized-user accounts to the credit bureaus, but practice varies by issuer. See Do tradelines report to all 3 bureaus?
3. The cardholder adds you. Most issuers let the cardholder do this in their online account or with a phone call. Some issuers ask for your date of birth or Social Security number.
4. You don't need to carry or use the card. The cardholder can keep the card.
5. Check your credit report after the next statement or two. Your free reports are at AnnualCreditReport.com.

What's good: being added usually costs nothing, and you can stay on the card for years.

What's hard:

• You need someone with a seasoned, well-run card who says yes.
• Their future habits keep landing on your file. One missed payment or a maxed-out balance on their card can show up on yours.
• Money and relationships mix. Both of you need to know what you're agreeing to.
• The cardholder can remove you at any time.

Route 2: Pay for an authorized user tradeline

No one to ask? Rather not mix money and family? This is the route for you. A tradeline company adds you to a stranger's seasoned card. Here's how the process runs on tradelines.ai:

1. Choose a card by age and limit on the marketplace. You never see the cardholder's name or contact details.
2. Sign the agreement first. Payment instructions appear only after you sign.
3. Pay one price, from $349 per slot. No monthly fees.
4. The cardholder adds you. The tradeline typically posts 7–10 days after the cardholder's statement date.
5. You're on the card for one billing cycle. You never get the card or a card number.

What's good: there's no favor to ask, you pick the card's age and limit, and your ties to a stranger's spending end after one billing cycle.

What's hard:

• A paid tradeline costs money. See How much do tradelines cost?
• The term is set: one billing cycle, not years. After that, history that already reported follows the credit bureaus' own reporting and retention rules, which no tradeline company controls.
• It's the same authorized-user account in the end. Some lenders, mortgage underwriters especially, look harder at authorized-user accounts whichever route you used. See What lenders think of authorized user accounts.

Side by side

Which route fits you?

Here's our side, and we sell the paid route: if someone you trust has a seasoned card with on-time payments and a low balance, ask that person first. Being added is free and can last for years.

If you don't have that person, or that person's card isn't one you'd want on your file, the paid route exists for exactly that gap. Pick the card on fit, not on size: How to choose a tradeline that fits your file.

Two rules apply on either route:

• Authorized-user history works beside your own account, not instead of it. Open one account in your own name too. See How to build credit with no credit history.
• Being added removes nothing. If your file shows late payments or collections, an authorized-user account doesn't take them off. See what tradelines can't remove.
