Imagine landing in the United States with dreams of building a new life—maybe buying a car, renting an apartment, or even starting a small business. But then you hit a wall: you need credit, and most applications ask for a Social Security Number (SSN) you don’t have. This was Maria’s story, a recent immigrant from Mexico who arrived in Texas with ambition but no credit history. Like many newcomers, she felt stuck until she discovered the Individual Taxpayer Identification Number (ITIN). With it, she opened a secured credit card, started building her credit, and within a year, qualified for an unsecured card with rewards. Maria’s journey isn’t unique—it’s a path thousands take to establish financial stability in the U.S. In this guide, we’ll walk you through how to apply for an ITIN, use it to build credit, and navigate the U.S. financial system as a newcomer. Whether you’re an international student, a nonresident, or an immigrant, this post is packed with actionable advice, expert insights, and real-world examples to help you succeed.

What Is an ITIN, and Why Does It Matter for Building Credit?
An ITIN is a nine-digit number issued by the Internal Revenue Service (IRS) to individuals who need to file federal taxes but aren’t eligible for an SSN. It’s primarily a tax-processing tool, but its role extends beyond taxes. For immigrants, international students, or nonresident aliens, an ITIN can be a gateway to financial services like bank accounts and credit cards, which are critical for building a U.S. credit history. Unlike an SSN, an ITIN doesn’t authorize work or provide Social Security benefits, but it’s a legal alternative for financial identification. According to the IRS, over 4.6 million ITINs were issued or renewed in 2023, reflecting its importance for millions navigating life in the U.S.
Why does credit matter? In the U.S., your credit score—typically a FICO score ranging from 300 to 850—determines your ability to secure loans, rent apartments, or even land certain jobs. Without a credit history, you’re essentially invisible to lenders. For someone like Maria, who had a stellar credit record in Mexico, starting from scratch was frustrating because foreign credit doesn’t transfer to the U.S. An ITIN bridges this gap by allowing you to access credit-building tools, setting the foundation for financial inclusion. As NerdWallet explains, while issuers can’t legally require an SSN, they can deny you for lack of credit history, making an ITIN a critical first step.
Who Needs an ITIN?
Not everyone needs an ITIN, but it’s a lifeline for specific groups. Here’s who typically applies:
- Nonresident aliens required to file U.S. tax returns, like international students receiving scholarships.
- Resident aliens for tax purposes who don’t qualify for an SSN.
- Spouses or dependents of U.S. citizens or visa holders who need to be included on tax returns.
- Undocumented immigrants who earn income and must file taxes.
- Foreign business owners operating in the U.S. without an SSN.
For example, consider Raj, an international student from India studying at a U.S. university. His scholarship required him to file taxes, but he wasn’t authorized to work, so he couldn’t get an SSN. By obtaining an ITIN, Raj not only complied with tax laws but also opened a bank account and applied for a student credit card, kickstarting his credit journey. The IRS website provides detailed eligibility criteria, but the key is having a tax-filing obligation.
How to Apply for an ITIN: A Step-by-Step Guide
Applying for an ITIN can feel daunting, but it’s a straightforward process if you follow these steps. The IRS processes over 2 million ITIN applications annually, so you’re not alone. Here’s how to do it:
Step 1: Complete Form W-7
Download Form W-7 from the IRS website. This is the Application for IRS Individual Taxpayer Identification Number. Fill it out with your personal details, including your name, foreign address, and reason for applying (e.g., filing a federal tax return). Be precise—errors can delay processing, which typically takes 7–11 weeks.
Step 2: Gather Required Documents
You’ll need to prove your identity and foreign status. Acceptable documents include:
- A valid passport (preferred).
- National ID card with name, photo, and date of birth.
- U.S. driver’s license or foreign voter’s registration card.
- Birth certificate (required for dependents under 18).
The IRS requires original documents or certified copies from the issuing agency. For example, Maria sent her Mexican passport and a certified copy of her birth certificate. Check the IRS’s identification requirements for a full list.
Step 3: Attach a Federal Tax Return
Most ITIN applications must include a completed federal tax return, like Form 1040 or Form 1040-NR. This proves your tax-filing need. Exceptions exist for dependents or those claiming tax treaty benefits—see IRS guidelines for details. Raj, for instance, attached his Form 1040-NR to report his scholarship income.
Step 4: Submit Your Application
Mail your W-7, tax return, and documents to:
Internal Revenue Service
Austin Service Center
ITIN Operation
P.O. Box 149342
Austin, TX 78714-9342
Alternatively, visit an IRS Taxpayer Assistance Center or work with a Certified Acceptance Agent (CAA), who can verify documents for a fee. Processing times vary, so apply early to avoid delays.
Step 5: Receive Your ITIN
Once approved, the IRS mails your ITIN letter. Keep it safe—it’s your key to financial services. If denied, the IRS will explain why, and you can reapply with corrections.
Pro Tip: ITINs expire if not used on a tax return at least once every three years, so file taxes regularly to keep it active, as noted by Capital One.
Using Your ITIN to Build Credit
With your ITIN in hand, you’re ready to build credit. But where do you start? Since you likely have no U.S. credit history, traditional unsecured credit cards may be out of reach. Here are proven strategies to establish and grow your credit:
Open a Secured Credit Card
Secured credit cards are ideal for beginners. You deposit cash—typically $200–$500—which becomes your credit limit. The issuer reports your payments to the three major credit bureaus (Experian, Equifax, TransUnion), building your credit history. For example, Maria opened a Capital One Platinum Secured Credit Card with a $300 deposit. Within six months, her responsible use—paying on time and keeping balances low—earned her a FICO score of 650.
- Top Secured Cards for ITIN Holders:
- Capital One Platinum Secured: No annual fee, potential credit limit increase in 6 months.
- Discover it Secured: 2% cashback at gas stations and restaurants, no SSN required.
- Firstcard Secured: Up to 4% APY on deposits, ITIN-friendly.
Use your card for small purchases and pay the balance in full each month to avoid interest. Bankrate highlights secured cards as a low-risk way to build credit.
Apply for a Credit Builder Loan
Credit builder loans, offered by companies like Self, work differently. You make monthly payments into a savings account, and the lender reports these to credit bureaus. Once the loan term ends (e.g., 12 months), you get your money back, minus fees. This helped Raj build credit while saving $600 over a year. Payments are reported as “on-time,” boosting your score.
Become an Authorized User
If you have a trusted friend or family member with good credit, ask to be added as an authorized user on their credit card. Their payment history can positively impact your credit report, even if you don’t use the card. Ensure the primary cardholder has a strong payment record, as late payments can hurt your score.
Monitor Your Credit Progress
After 3–6 months of responsible credit use, you’ll likely have a credit score. Check your credit report for free via AnnualCreditReport.com or Experian’s ITIN-friendly service. Request your report by mail using your ITIN, as online access may require an SSN. A score of 600–700 opens doors to unsecured cards with better terms.
Comparison Table: Credit-Building Options for ITIN Holders
| Option | How It Works | Pros | Cons | Best For |
|---|---|---|---|---|
| Secured Credit Card | Deposit cash for credit limit; use card and pay on time. | Easy to qualify, builds credit fast, some offer rewards. | Requires upfront deposit, may have fees. | Newcomers with some savings. |
| Credit Builder Loan | Make monthly payments into savings; payments reported to bureaus. | No upfront deposit, builds savings, low risk. | Small fees, no immediate credit access. | Those who want to save while building credit. |
| Authorized User | Added to someone’s card; their payment history impacts your credit. | No application, no deposit, fast credit boost if cardholder is reliable. | Dependent on cardholder’s habits, no control over account. | Those with trusted contacts. |
Challenges and Misconceptions About ITIN Credit Building
Building credit with an ITIN isn’t without hurdles. Some issuers, like Discover and USAA, don’t accept ITINs for credit cards, limiting your options. Others may perceive ITIN applicants as higher risk, as noted by Forbes. Additionally, you can’t transfer foreign credit history, so you’re starting from zero. Maria faced rejections before finding ITIN-friendly issuers like Capital One and American Express.
Common misconceptions also persist:
- Myth: ITINs are only for taxes.
Truth: ITINs enable banking, credit applications, and even driver’s licenses in some states. - Myth: ITIN loans don’t build credit.
Truth: Timely repayments on ITIN loans, like those from AMRESCO, are reported to bureaus. - Myth: You need an SSN to check your credit score.
Truth: You can request credit reports by mail using your ITIN, per Self.
Patience is key. It takes 6–12 months to establish a solid credit profile, but consistent effort pays off.
Expert Tips for Maximizing Your Credit-Building Journey
To accelerate your progress, follow these expert-backed strategies:
- Pay on Time, Every Time: Payment history is 35% of your FICO score. Set up autopay to avoid missed payments.
- Keep Credit Utilization Low: Use less than 30% of your credit limit. For a $500 limit, keep balances under $150.
- Avoid Multiple Applications: Each hard inquiry can ding your score by 5–10 points. Use pre-approval tools to check eligibility without impacting your score.
- Diversify Credit Types: After building initial credit, consider adding an installment loan (e.g., auto loan) to show you can handle different credit types.
- Track Your Score: Use free tools like Experian’s app or Capital One’s CreditWise to monitor progress.
Financial counselor Ana Gonzalez-Ribeiro, quoted in Self’s blog, emphasizes responsible use: “Pay at least the minimum on time, but aim to pay in full to avoid interest.” This approach helped Maria graduate to an unsecured card with a $2,000 limit in just 10 months.
