To get a credit card without a Social Security number, you must provide identification that functions similarly, such as an individual taxpayer identification number, explains NerdWallet. Without such identification, you might not be able to obtain a credit card.
If you have a credit history or a Social Security number abroad, you can apply for credit cards in your home country. Certain U.S. banks, such as Citibank, provide credit cards without an SSN under certain circumstances, such as international student status, reports Investopedia. This secured credit card helps you establish credit in the United States without having a Social Security number. As of 2008, Bank of America allows you to obtain a credit card as long as you have maintained a checking account with them for more than three months without an overdraft, explains CreditCards.com.
