Authorized user tradelines vary considerably in age, credit limit, balance and account history. If you’re comparing available tradelines, those differences matter more than simply choosing the oldest account or highest credit limit.
The right choice depends on your existing credit profile and what you’re trying to accomplish. Understanding the information attached to an authorized user account can help you compare options more carefully and set realistic expectations.
Start With Your Current Credit Profile
Before comparing authorized user tradelines, review your own credit reports. Look at the age of your accounts, revolving balances, available credit and payment history.
This gives you context for evaluating another account. A consumer with a relatively young credit file may look at an established account differently than someone primarily concerned with revolving utilization.
What Appears on an Authorized User Tradeline?
An authorized user tradeline is a credit card account on which another person is the primary cardholder. When the issuer reports authorized users, information associated with that account may appear on the authorized user’s credit report.
Depending on the issuer and bureau, reported information can include:
- Account opening date
- Credit limit
- Reported balance
- Payment history
- Account status
The primary cardholder remains responsible for the account. Being an authorized user is different from opening and managing a primary credit account yourself.
Six Things to Compare Before Choosing a Tradeline
1. Account Age
An older credit card can add established account history when that history is reported to an authorized user’s credit file. This makes age an important comparison point, particularly for someone with a younger credit history.
Older does not automatically mean better. Account age should be considered alongside the account’s other characteristics.
2. Credit Limit
Credit limit is another useful comparison point. A higher limit can increase the amount of available revolving credit reflected on a report when the account is included in utilization calculations.
However, the limit alone does not tell you whether an account is a good fit. The reported balance matters too.
3. Account Utilization
Utilization measures the balance on a revolving account relative to its credit limit. A $500 balance on a $10,000 account represents 5% utilization, while a $5,000 balance represents 50%.
This is why comparing balances and limits together provides more useful information than looking only at the advertised credit limit.
4. Payment History
Review the account’s payment history. An established account with consistent payment history is very different from an account containing late payments or other negative information.
The primary cardholder continues to control the account, so future account activity can also affect what gets reported.
5. Reporting
An authorized user account needs to appear on a consumer’s credit report before its information can potentially be considered by a credit scoring model.
Reporting practices can vary by issuer and credit bureau. Consumers should not assume that every authorized user account will report identically across Equifax, Experian and TransUnion.
6. Price
Price should be evaluated alongside the characteristics of the account. A more expensive tradeline is not automatically a better tradeline.
Compare what you’re paying for, including account age, limit and other available information, rather than making a decision based solely on price.
Is Account Age or Credit Limit More Important?
Neither factor should automatically determine your choice. They address different parts of a credit profile.
Account age relates to credit history. Credit limit can affect available revolving credit and utilization calculations. Depending on your existing accounts, one characteristic may be more relevant than the other.
If account history is your primary consideration, our guide to primary vs. seasoned tradelines explains how seasoned accounts differ from newer credit accounts.
Can an Authorized User Tradeline Increase Your Credit Score?
An authorized user account can affect credit when its information is reported and considered by the scoring model being used. That does not mean every authorized user will receive the same result.
Credit scores consider information across the credit report. Existing accounts, payment history, utilization, derogatory information, inquiries and the age of the overall credit file can all influence the calculation.
For that reason, no responsible provider can predict an exact number of points that a particular tradeline will add to every consumer’s score.
Authorized User Tradelines Are Not Primary Accounts
This distinction is important. A primary account is opened in your name and represents credit for which you are directly responsible. An authorized user account belongs to another primary cardholder.
Lenders may evaluate much more than a numerical credit score. Depending on the application, they may consider income, debt obligations, primary account history and other underwriting information.
An authorized user tradeline therefore should not be treated as a substitute for responsibly establishing and maintaining credit in your own name.
What Can Make a Tradeline a Poor Choice?
A large limit or old opening date should not distract from other account characteristics. Potential concerns can include:
- High reported utilization
- Late-payment history
- Uncertainty about bureau reporting
- An account that does not fit your credit profile
- A price that does not make sense for the account characteristics
Consumers should also be skeptical of promises involving guaranteed score increases, guaranteed financing or exact results. Credit profiles and scoring outcomes vary.
How Many Authorized User Tradelines Do You Need?
More is not automatically better. Adding multiple accounts without understanding how they fit your credit profile can increase cost without necessarily producing the result you expect.
Start by identifying what you’re trying to address in your existing file. Our guide on how many tradelines you should have explores this question in more detail.
Compare Tradelines Side by Side
When several authorized user tradelines are available, compare them using the same criteria rather than evaluating each one independently.
- How old is the account?
- What is the credit limit?
- What balance or utilization is reported?
- What does the payment history look like?
- What reporting information is available?
- How much does the tradeline cost?
This approach makes it easier to identify meaningful differences between accounts. For additional guidance, see our guide to choosing a tradeline.
Buying Authorized User Tradelines Through Coast
Coast Tradelines offers authorized user tradelines with different account ages, credit limits and price points. Customers can compare available accounts rather than relying on a one-size-fits-all recommendation.
Before purchasing, review the available account information and consider how the tradeline relates to your existing credit file. Age and credit limit can be useful comparison points, but utilization, account history, reporting and cost also deserve consideration.
The goal should be to make an informed selection based on the characteristics of the account and your own credit profile, rather than choosing a tradeline based on promises of a specific score increase.
