Being added as an authorized user on someone else’s credit card can build your credit, often within one or two billing cycles, as long as the card issuer reports authorized users to the credit bureaus and the underlying account has a strong history. The account’s full record — its age, payment history, balance, and credit limit — attaches to your credit file once reported. For someone with little or no credit history, that inherited track record can produce a noticeable score increase quickly. For someone whose primary cardholder pays late or carries high balances, the same mechanism can drag a score down.
What the Account Itself Has to Look Like
Simply being added isn’t enough. The account needs specific qualities before it helps you.
- Age. Older accounts contribute more. A card the primary cardholder has held for ten or fifteen years appears on your file as though you had access to credit for that whole stretch, which can dramatically raise the average age of your credit.
- Payment history. A clean record of on-time payments strengthens your file. A single late payment by the primary cardholder can hurt your score just as easily, because you inherit the bad along with the good.
- Utilization. Scoring models look at how much of the available limit is being used. Keeping utilization below 30 percent avoids negative effects, and single digits is better. A high balance relative to the limit can lower your score.1Experian. What Is a Credit Utilization Rate?
- Credit limit. A high limit on the shared card raises your total available credit, which lowers your overall utilization ratio even if you never spend on the card.
One more condition sits outside the account itself: the issuer has to actually report authorized users, and ideally to all three bureaus. Not every issuer does. Some report to only one or two, and some don’t report authorized users at all. Confirm the issuer’s reporting practice before anyone goes through the trouble of adding you, because an unreported account does nothing for your credit no matter how pristine it is.
FICO 8, FICO 9, and VantageScore 3.0 and 4.0 all include authorized user accounts in their calculations. FICO’s versions carry filters built to catch tradeline renting, where strangers pay to be added to accounts purely for a score bump; a genuine arrangement between family members or close friends isn’t the target.2American Express.

How Much Your Score Can Actually Move
The size of the increase depends on where you start. Someone with no credit history at all tends to see a bigger jump than someone who already has several accounts in good standing. Industry surveys have found that people with scores below 550 experienced roughly a 10 percent score improvement within 30 days of being added, with continued gains over the following year. Someone who already has a moderate score and some history may see a more modest bump of 10 to 25 points. The actual number depends on the primary cardholder’s account quality and your existing profile.
How Long It Takes to Show Up
The account won’t appear on your credit report the day you’re added. Issuers send data to the bureaus at the end of each billing cycle, which runs roughly 28 to 31 days. It can take one or two full cycles before the account history reaches your file.3Experian. Are Authorized-User Accounts Reported to All Three Bureaus? Check your credit report after about 60 days to confirm the account is there. If it isn’t, the issuer may not report authorized users, or the account may have been added with incomplete identifying information.
Once reported, the account stays on your file as long as it remains open and you stay on it. The positive effect depends on the account continuing to be reported each month in good shape.
What Can Go Wrong
The biggest risk is inheriting negative account behavior you can’t control. If the primary cardholder misses a payment, maxes out the card, or lets the account slip toward collections, the damage shows up on your report too. You have no say in how they manage the account, and you may not learn about a missed payment until after it has already hit your credit.
Being an authorized user does not make you legally responsible for the balance. The primary cardholder is the only person obligated to pay the debt.4Consumer Financial Protection Bureau. I Was an Authorized User on My Deceased Relative’s Credit Card Account. Am I Liable to Repay the Debt? If a collector contacts you about a balance on an account where you were only an authorized user, point to your credit report to show your status and ask the collector to produce any signed agreement.
If the primary cardholder files for bankruptcy, the bankruptcy itself doesn’t transfer to your file, but any missed payments on the shared account leading up to that filing can still show up on your report and affect your score.5Experian. Authorized User Who Has Declared Bankruptcy
How to Get Added
The primary cardholder initiates the request, either through the issuer’s online portal or by calling customer service. To add you, they typically need:
- Your full legal name
- Your date of birth
- Your Social Security number
- Your mailing address
The Social Security number matters most. Without it, the issuer often cannot match you to the correct credit file, and the account won’t appear on your report — the entire point of the exercise.6Experian. What Is an Authorized User on a Credit Card?
There is no universal minimum age. Some issuers set the floor at 13, others at 15 or 18, and several large issuers publish no minimum at all.7Experian. What Is the Minimum Age for an Authorized User? That makes authorized user status one of the few ways a minor can start building credit before 18.
Most standard cards don’t charge a fee for adding an authorized user, but certain premium cards charge $75 or more per additional user. The primary cardholder should check the card’s terms before adding anyone. A physical card in your name usually gets mailed to the primary cardholder’s address, with delivery taking anywhere from a few days to a few weeks. If the only goal is credit building, the primary cardholder can keep that physical card; the reporting benefit works the same whether you ever make a purchase or not.
Getting Removed Later
Either party can request removal. The primary cardholder contacts the issuer, or you can call directly and ask to be taken off. Issuers process these requests without much friction because you have no payment obligation.8Experian. Remove Authorized User Accounts from Credit Report
Once you’re removed, the account and its entire history come off your credit report and stop factoring into your scores.9Experian. Removing Yourself as an Authorized User Could Help Your Credit Removal can either help or hurt. If the account was old, well-paid, and lightly used, losing it may drop your score. If the account had late payments or high balances pulling you down, removal should improve things. If the account still appears on your report after you’ve been taken off, contact each bureau to dispute the entry.
When It’s Not Enough on Its Own
Authorized user status is one of the fastest ways to build credit from zero, but it leaves your profile tied to someone else’s behavior and their decision to keep you on the account. For most people starting out, the stronger play is to pair it with an account in your own name.
- Secured credit cards. You put down a cash deposit, often $200 to $500, which becomes your credit limit. You use the card like any other, and the issuer reports your activity. You’re the primary account holder, which some lenders weigh more heavily than authorized user history.
- Credit-builder loans. A bank or credit union holds a small loan in a savings account while you make monthly payments that get reported to the bureaus. When the loan is paid off, you receive the funds.
- Becoming a primary cardholder on a starter card. Some issuers offer unsecured cards aimed at people with limited history. Limits are low and rewards are thin, but the account is yours.
Combining an authorized user tradeline on a well-managed family card with your own secured card or credit-builder loan gets you the quick score lift and independent history at the same time. That way, if the primary cardholder changes how they use the card or removes you, your credit doesn’t go with it.
