How becoming an authorized user on someone else's credit card can jumpstart your credit history in the US.
Resumen de la guía
Cómo convertirse en un usuario autorizado de la tarjeta de crédito de otra persona puede impulsar su historial crediticio en los EE. UU.
Marco
Análisis profundo
An authorized user is someone added to another person's credit card account with permission to make purchases. The key feature for credit building is that many card issuers report the entire account history, including the date the account was opened, credit limit, and payment record, to the authorized user's credit file. This can instantly add years of positive credit history to a new immigrant's otherwise empty credit report.
The primary cardholder remains legally responsible for all charges on the account, including those made by authorized users. The authorized user has no legal obligation to pay. This asymmetric liability structure means the primary cardholder assumes financial risk when adding someone, which is why this arrangement typically occurs between family members or close friends with high mutual trust.
FICO scoring models incorporate authorized user tradelines into credit scores, though FICO 8 and later versions include logic to detect and reduce the impact of tradelines that appear to be purchased rather than based on genuine relationships. VantageScore 4.0 also weights authorized user accounts but gives them less influence than the consumer's own primary accounts.
Issuer reporting policies vary significantly. American Express reports authorized users to all three bureaus and accepts ITIN for authorized user enrollment. Chase reports to all three bureaus and generally accepts ITIN. Capital One reports to all three bureaus. Bank of America reports but may require SSN for authorized users. Discover reports but policies on ITIN vary by card product.
Before being added, call the issuer's customer service line to confirm three things: that they report authorized user accounts to all three bureaus, that they accept ITIN (if applicable) for the authorized user, and that the full account history (not just activity from the date of addition) will be reported. Some issuers only begin reporting from the date the authorized user is added, which provides less immediate benefit.
Credit unions and community banks often have different reporting practices than national issuers. Some report authorized users; many do not. Community Development Financial Institutions (CDFIs) that serve immigrant populations may have specific policies. Always verify reporting practices directly with the institution rather than relying on general information.
The ideal authorized user account has a long history (5+ years), a high credit limit ($10,000+), a perfect payment record (zero late payments), and low utilization (below 10% of the limit). These characteristics contribute the maximum positive impact to the authorized user's credit file across all scoring factors: payment history, utilization, age of accounts, and credit mix.
Avoid accounts with any late payments, high utilization, or recent negative marks. Negative history on the primary account also appears on the authorized user's credit file. A single 30-day late payment on the primary account will damage the authorized user's credit just as it damages the primary cardholder's score.
The account's age is particularly valuable for new immigrants. If a family member has a credit card opened in 2010, the authorized user's average account age immediately includes this 15+ year tradeline. Since average age of accounts contributes approximately 15% to the FICO score, this single addition can have a significant impact on a thin credit file.
A legitimate authorized user arrangement involves a genuine relationship between the primary cardholder and the authorized user, typically family members or close friends. The addition is made for the purpose of credit building, convenience, or shared expenses. This practice is legal and widely used; according to a 2019 CFPB report, approximately 33% of all credit card accounts had at least one authorized user.
Purchased tradelines involve paying a stranger to add you as an authorized user on their credit card, typically through a tradeline brokerage company. Prices range from $150 to $1,500+ depending on the account's age and credit limit. While not explicitly illegal, FICO 8 and later versions are designed to detect and minimize the scoring impact of these arrangements.
Banks consider purchased tradelines a form of misrepresentation. If a lender discovers that an applicant's credit history is inflated by purchased tradelines, it can deny the application, close the account, and potentially flag the applicant for fraud. The OCC and FDIC have issued guidance warning financial institutions about the risks of tradeline renting.
Establish clear expectations with the primary cardholder before being added. Discuss whether you will receive a physical card and make purchases, whether you are being added solely for credit-building purposes (no card issued), spending limits if a card is provided, and how long the arrangement will last. Written agreements, while not legally binding as contracts, help prevent misunderstandings.
Monitor the primary account's status regularly. If the primary cardholder begins making late payments or increasing utilization, the authorized user's credit file is negatively affected. Check your own credit report monthly (free through Credit Karma or AnnualCreditReport.com) to verify the authorized user account is being reported correctly and positively.
Have an exit strategy. If the relationship deteriorates or the primary account develops negative marks, the authorized user should request removal. Removal can be initiated by either party. Call the card issuer to request removal, and then verify with each bureau that the tradeline has been deleted from your credit report. Removal typically takes one to two billing cycles to reflect on credit reports.
Authorized user status is a bootstrapping tool, not a permanent credit strategy. Lenders evaluating mortgage or auto loan applications distinguish between authorized user accounts and primary accounts. Underwriters at major lenders routinely exclude authorized user tradelines when calculating debt-to-income ratios and assessing creditworthiness for large loans.
After 3 to 6 months as an authorized user, you should have sufficient credit visibility to qualify for your own secured credit card. After 12 months of on-time payments on your own card, you may qualify for an unsecured card. The goal is to build a portfolio of primary accounts that demonstrate your own creditworthiness independent of anyone else's account.
A strong credit profile for a newcomer after 2 to 3 years typically includes: one authorized user account (for age boost), one or two primary credit cards (for payment history and utilization), and one installment loan or credit builder loan (for account type diversity). This mix covers all five FICO scoring categories: payment history (35%), utilization (30%), age (15%), credit mix (10%), and new credit (10%).

Preguntas frecuentes
Yes, at many major issuers. American Express, Chase, and Capital One generally accept ITIN for authorized user enrollment. Call the issuer to confirm before proceeding, as policies can vary by card product.
Typically within one to two billing cycles (30 to 60 days) after being added. The tradeline appears with the account's full history if the issuer reports historical data, or from the date of addition if they do not.
Yes. Being added to two or three well-chosen accounts can diversify your reported credit limits and account ages. However, more than three authorized user tradelines with no primary accounts may trigger FICO 8's filtering algorithms.
The tradeline remains on your credit report but shows as closed. Closed accounts with positive history continue to contribute to your score for up to 10 years after closure under standard FCRA reporting timelines.
