If you’re learning how credit works in the US, check our Complete Credit Guide for Beginners first to understand the basics before adding yourself as an authorized user.
Short Answer
Yes, becoming an authorized user on someone else’s credit card can help build or improve your credit score. When the primary cardholder has a strong credit history and low balances, the account may appear on your credit report and contribute positively to your credit profile. However, the impact depends on how the account is managed and whether the card issuer reports authorized users to the credit bureaus.
What Is an Authorized User?
An authorized user is a person who is added to someone else’s credit card account and allowed to make purchases with that card. The primary cardholder remains responsible for paying the balance and managing the account.
When you become an authorized user, the credit card account may appear on your credit report. If the account has a long history of on-time payments and low credit utilization, it can strengthen your credit profile.
This strategy is often used by people who want to build credit from zero or improve a limited credit history.

How Authorized User Accounts Affect Your Credit Score
Credit scores are calculated based on several factors. When an authorized user account is added to your credit report, it can influence some of these factors.
The most important ones include:
Payment History
Payment history is the most important factor in most credit scoring models. If the primary cardholder always pays on time, the account can contribute positively to your credit history.
However, if the account has late payments, those may also affect your credit profile.
Credit Utilization
Credit utilization measures how much of the available credit is being used.
For example:
Credit limit: $5,000
Balance: $500
Utilization: 10%
Low utilization is generally considered positive for credit scores. If the cardholder keeps balances low, this can help improve your credit profile as well.
You can learn more about this concept in our guide on credit utilization and how it affects your credit score.
Length of Credit History
Another factor is the age of the account.
If the credit card has been open for many years, it can extend the average age of your credit accounts. Older accounts often strengthen a credit profile.
This is one reason why authorized user accounts sometimes help people increase their credit score faster.
When Being an Authorized User Helps Build Credit
Becoming an authorized user can be helpful in several situations.
Building Credit From Scratch
People who have never used credit before may benefit from being added to a well-managed account. This can help establish an initial credit history.
Recovering From a Thin Credit File
If you have very limited credit history, a strong authorized user account may improve the overall profile lenders see.
Learning Responsible Credit Behavior
For younger individuals or newcomers to the U.S. credit system, becoming an authorized user can be a way to learn how credit cards work without being fully responsible for the account.
However, it is important that the primary cardholder manages the account responsibly.
When Authorized User Status May Not Help
Although becoming an authorized user can help in many cases, it is not guaranteed to improve a credit score.
Several factors can limit its impact.
The Card Issuer Does Not Report Authorized Users
Some credit card companies do not report authorized user accounts to credit bureaus. If the account is not reported, it will not affect your credit score.
High Balances
If the cardholder uses most of the available credit, the account may show high utilization. This could potentially lower your credit score instead of improving it.
Late Payments
Any late payments made on the account may also appear on your credit report. This could damage your credit profile.
For this reason, it is important to become an authorized user only on accounts with strong payment history.
Risks of Authorized User Accounts
Before becoming an authorized user, it is important to understand the potential risks.
Lack of Control
The primary cardholder controls the account. If they increase balances or miss payments, your credit profile may be affected.
Removal From the Account
The primary cardholder can remove an authorized user at any time. If that happens, the account may disappear from your credit report.
Not a Complete Credit Strategy
While authorized user accounts can help build credit, they should not be the only strategy. Building your own credit accounts is usually necessary for long-term credit growth.

Authorized User vs Joint Account
Some people confuse authorized users with joint credit accounts.
These two arrangements are different.
Authorized User
The primary cardholder owns the account and is responsible for payments. The authorized user simply has permission to use the card.
Joint Account
Both people are legally responsible for the account and share responsibility for the balance.
Joint accounts are less common today, while authorized user accounts are widely used for credit building strategies.
How to Add an Authorized User
Adding an authorized user is usually simple.
Most credit card issuers allow the primary cardholder to add an authorized user through their online account or customer service.
The card issuer may ask for basic information such as:
- name
- date of birth
- address
In some cases, the issuer may request a Social Security Number, although not all banks require it.
Once the authorized user is added, the credit card issuer may begin reporting the account to credit bureaus within one or two billing cycles.
Tips for Using the Authorized User Strategy Safely
If you are considering becoming an authorized user, these tips can help reduce risk.
Choose a primary cardholder who:
- always pays on time
- keeps balances low
- has an account that has been open for several years
Avoid accounts that:
- have high balances
- have missed payments
- are frequently maxed out
Responsible account management is essential for the authorized user strategy to work effectively.
