​A Beginner’s Guide to US Credit Cards: How to Build Your Credit Score from Scratch

​Welcome back to Bank.aambublog.com! If you are new to the United States or just starting your financial journey, you will quickly realize that cash isn’t always king here—Credit is.

​In the USA, having a good credit score is essential. It dictates whether you can rent an apartment, get a favorable rate on a car loan, buy a house, or sometimes even land a job. But how do you get a credit card if you don’t have a credit history? Let’s break it down.

1. What is a Credit Score?

​A credit score is a three-digit number (typically ranging from 300 to 850) that represents your creditworthiness. The most common system used by US banks is the FICO® Score.

  • Excellent: 800 to 850
  • Very Good: 740 to 799
  • Good: 670 to 739
  • Fair: 580 to 669
  • Poor: 300 to 579

​When you use a credit card and pay it back on time, your score goes up. If you miss payments, your score drops.

2. The SSN or ITIN Requirement

​To apply for most standard credit cards in the US, you need a Social Security Number (SSN). This is how the credit bureaus (Equifax, Experian, and TransUnion) track your financial behavior.

​If you are an international student or a new immigrant without an SSN, don’t worry! Many banks allow you to apply using an Individual Taxpayer Identification Number (ITIN) or by using your passport and visa details (banks like Bank of America and Deserve are very immigrant-friendly).

3. How to Get Your First Credit Card

​If you have zero credit history, major banks will likely decline your application for their premium reward cards. Here are the two best ways to start:

A. Secured Credit Cards

​This is the absolute best tool for beginners. With a secured card, you pay a refundable cash deposit upfront.

  • How it works: If you deposit $200, your credit limit is $200. You use it like a normal credit card and pay the bill every month.
  • The Benefit: Because your deposit protects the bank, anyone can get approved. After 6 to 8 months of on-time payments, the bank will usually upgrade you to an “unsecured” card and return your deposit.
  • Top Picks: Discover it® Secured, Capital One Platinum Secured.

B. Student Credit Cards

​If you are enrolled in a university, many banks offer student credit cards that do not require a prior credit history. They often come with small credit limits but offer great opportunities to build your FICO score while you study.

4. The Golden Rules of Credit Cards

​Once you get your first card, follow these three rules to build a fantastic credit score fast:

  1. Pay in Full, On Time: Never carry a balance. If you spend $100, pay the full $100 before the due date. You will never pay a single cent in interest if you do this.
  2. Keep Utilization Under 30%: Your “Credit Utilization” is how much of your limit you use. If your limit is $1,000, try never to have a balance higher than $300 at any given time.
  3. Don’t Apply for Too Many Cards: Every time you apply, it places a “hard inquiry” on your report, which temporarily lowers your score. Stick to one card for the first six months.

Conclusion

​Building credit in the USA is a marathon, not a sprint. Start small with a secured card, pay your balance in full every month, and within a year, you will have a solid credit score ready for bigger financial goals!

Frequently Asked Questions (FAQs)

Q1. How long does it take to build a good credit score from scratch?

Answer: It generally takes about six months of consistent, on-time payments with your first credit card to generate your official FICO® Score. If you keep your credit utilization low and pay your bills in full, you can easily reach a “Good” score (around 670+) within the first year.

Q2. Can I get a US credit card without a Social Security Number (SSN)?

Answer: Yes! While an SSN is the standard, many banks accept an ITIN (Individual Taxpayer Identification Number). Additionally, traditional banks like Bank of America and modern fintech companies like Deserve allow international students and expats to apply using just their passport and US visa details.

Q3. Does using my debit card help build my credit score?

Answer: No. A debit card uses your own money directly from your checking account. Because you are not borrowing money from a lender, debit card activity is not reported to the three major credit bureaus and has zero impact on your credit score.

Q4. What happens if I only pay the “Minimum Amount Due” on my credit card bill?

Answer: If you pay only the minimum, you will avoid late fees and protect your credit score from dropping. However, the bank will charge you high interest (often 20% to 29% APR) on the remaining balance. To avoid paying interest entirely, you should always pay the full “Statement Balance” every month.

Q5. Is it bad to cancel my first credit card after I get a better one?

Answer: Yes, it is usually better to keep your first credit card open, especially if it has no annual fee. The length of your credit history makes up 15% of your total credit score. Closing your oldest account shortens your credit history and can temporarily lower your score.
