US credit card without an SSN: how your American credit file begins

In the US, a credit card is more than a way to pay. It is usually the first entry in your credit file, and that file later decides your apartment, your car, your phone contract and your business loan. Without a Social Security Number, the door looks shut. It isn't: your file is built from your details and your payments, not from one particular number. Here is what a card issuer may ask of you, how a secured card works and what makes your score grow.

1Why the card asks for an SSN

Apply for a credit card in the US and the form almost always has a field for your Social Security Number. That is not because a law bans cards without an SSN. It is because of how the American credit system works. Lenders report accounts and payments to the credit bureaus, and the big three are Equifax, Experian and TransUnion. Anyone reviewing an application checks with them, and for the bureaus the SSN is a convenient way to match data to a person.

Convenient is not the same as essential. Experian itself says it does not match data by SSN alone but by all the identifying details a lender reports: name, addresses from recent years and date of birth. So, according to Experian, you can have a credit file and a score without having an SSN. Experian does not treat an ITIN as an SSN in your file; there it counts as an invalid SSN, and the bureau relies on the other details.

Two things follow for you. First, consistent details matter. Write your name on every application exactly as it appears in your passport, and use the same address for as long as you can be reached there. Second, what you lack at the start is not the number but the history. An issuer who can't find you in any file knows nothing about you, and that is exactly where the path begins.

How bank accounts and credit history fit together is covered in our overview US bank account and US creditworthiness, and why your European credit rating counts for nothing in the US is explained in The US credit score for immigrants.

2What a card issuer may check

To the bank, a credit card account is an account like any other. Anti-money-laundering rules require it to identify you with your name, date of birth, address and an identification number. As a non-US person, instead of a tax number you can give, for example, your passport number and issuing country. One rule applies only to credit cards: before extending credit, the bank may also obtain the required details from a third-party source, such as a credit bureau.

Beyond your identity, the issuer checks your creditworthiness. That is governed by the Equal Credit Opportunity Act, implemented through Regulation B, which sets out what a lender may and may not consider. It expressly allows the issuer to consider your immigration status and whether you have permanent residency, along with other information it needs to assess its rights to repayment. So an issuer may ask whether and how long you will be in the US, and factor that into its decision.

In return, it owes you an answer. It must notify you of its decision within 30 days of a complete application. If it declines, it must do so in writing, giving the specific reasons or telling you that you can request them within 60 days. Those reasons are valuable: they tell you whether the issue was the missing file, your address or your status. The table sums up the rules.

3The ITIN: a tax number, not a master key

The ITIN, or Individual Taxpayer Identification Number, is a nine-digit IRS tax number for people who need a US tax number but can't get an SSN. It is used for federal tax purposes only. It does not authorize work in the US, does not change your immigration status and is not an ID outside tax matters.

So why is it still so useful for a credit card? Because, according to Experian, lenders usually ask for an SSN, and without one, the ITIN at least lets you give a number issued to you by a US authority. What the ITIN is not: a guarantee. It fills a form field; it doesn't open a door. Each issuer decides for itself whether to accept applications with an ITIN. What the ITIN does for banking, cards and credit is covered in more detail in The ITIN as your key to banking, cards and credit.

Normally you only get an ITIN with your first US tax return, which often means the following year. With ITIN Express we apply for it right away, through a special procedure we developed together with the attorneys on the firm's team, with no prior tax return. For applications from abroad, the IRS quotes nine to eleven weeks of processing time, and the same during peak season from January 15 to April 30; the decision to issue rests solely with the IRS. If the ITIN is not used on a federal tax return for three tax years, it expires. That is why it comes with an annual US tax return that keeps it active.

4The secured card: a deposit for a credit line

The usual first step is a secured credit card. The consumer protection agency CFPB describes it like this: you put down a deposit, and your credit limit matches that deposit. The issuer's risk is low, which is why a secured card is the one people without a credit file can get. For you it is still a real credit card: you shop with it, get a monthly statement and pay it off.

The point that matters isn't printed on the front: the card has to report your payments to the credit bureaus, and not every card does. The CFPB advises asking the issuer whether it reports to the bureaus; only then does the card build a history. Ideally it reports to all three major ones. The CFPB also points out that fees and interest on secured cards can be high. Pay the full balance every month and you pay no interest.

The CFPB also describes what comes next: once you show you pay on time, your limit may go up and your deposit may be returned. After that, regular cards with no deposit come within reach. When that happens is up to each issuer and its own criteria.

5What makes your score grow

The widely used FICO score and most other scores run on a scale from 300 to 850. For a FICO score to exist at all, your file needs at least one account that has been reported to a major bureau for six months or more, and at least one update in the last six months. So six months after your first card is the earliest possible point, not a guaranteed one.

FICO is open about how the score is built: payment history 35 percent, amounts owed 30 percent, length of credit history 15 percent, new credit 10 percent and credit mix 10 percent. For your first card, that mostly means two things. On time, according to the CFPB, means the payment reaches the issuer by the due date; if you pay by mail, send it a few days early. And scores look at how close you are to your limit. The CFPB cites some experts' advice to use no more than 30 percent of your limit. With a small limit, you hit that fast.

Length of history is the part you can't speed up. So don't close your first card as soon as a better one comes along; it is the oldest account in your file. And don't send out lots of applications at once: new credit counts in your score, and every application leaves a trace.

6More building blocks: credit builder loans and authorized users

Besides the secured card, the CFPB names other ways to get started. With a credit builder loan, you pay first and get the money later: the bank puts the loan amount into a locked account, you pay it off in installments over six to 24 months, and the bank reports the payments to the credit bureaus. In your file it counts as an installment loan, which improves your credit mix.

A second route is to be added as an authorized user on someone else's card, such as a family member who already lives in the US. You are not liable for the card, and its history can show up in your file. The CFPB points out, however, that newer scoring models give these accounts less weight and that this does not necessarily build your own history. For readers without relatives in the US, this route rarely matters.

7Account, address and phone number before the card

Before you apply for your first card, you will usually have an account with a US bank. You pay the secured card's deposit from there, and you pay off your statements from there. The documents the bank asks for are listed in Opening a US bank account: the documents.

The address matters just as much. The law requires a street address, and that is where your card, PIN and statements go. The credit bureaus store your addresses from recent years as part of your file, and moving often makes matching harder. An address where mail reliably reaches you is therefore not a detail but part of your credit history. You also need a US phone number for the bank's security codes; more on that in A US phone number for banks and agencies.

Account, address, phone number, ITIN and first card together are exactly what US Bank Account Opening sets up for you, with a single bank appointment in the US.

8Check and protect your file

As soon as your first card is reported, you have a file, and you should know what is in it. According to the Federal Trade Commission (FTC), the three nationwide credit bureaus each give you a free report once a week through AnnualCreditReport.com, the only site authorized for this. The FTC warns against sites that advertise free scores and pose as this source. Check that your name, address and date of birth are correct and that your card shows up with the right payments.

You can report errors directly to the credit bureau or to the issuer that supplied the data. If someone misuses your card, Regulation Z caps your liability for unauthorized use before you report it at $50. Still, report loss or theft right away.

9When your SSN comes later

Many readers build their file with an ITIN and later get an SSN, for example with a work visa or a green card. Then the question is what happens to the history. The credit bureaus match data using all identifying details, not just the number. Experian explains that you can ask the bureau directly to update your personal details, with proof, and that changes you give your lenders are passed on to the bureaus.

In practice: give your card issuers and banks your new SSN as soon as you have it, then check your reports at all three bureaus. Your name, address and date of birth stay the same, and that is what the matching relies on. Our view is in the box.
