If you have an employer identification number (EIN) — a nine-digit tax ID number assigned to your business by the IRS — you can use it to apply for a small-business credit card. But you will almost always have to also provide a Social Security number.
That’s because most small-business cards require applicants to personally guarantee the debt on the card. In other words, you are still responsible for paying back any debt, even if your business goes under.
As a result, when you apply for a small-business card with an EIN, the issuer will typically use your Social Security number to check your personal credit. Many small-business cards require good to excellent personal credit (typically FICO scores of at least 690) for approval.

Keeping business separate
Despite the personal guarantee, the activity on your small-business credit card won’t necessarily appear on your personal credit report.
If you prefer to keep your business and personal accounts separate, then you can look for a card that reports only to commercial credit bureaus and not the consumer credit bureaus. Or you can look for one that doesn’t report payments at all.BBVA Visa® Business Rewards Credit Card, doesn’t report small-business card activity to any of the credit bureaus, consumer or commercial.
If the card does report to the consumer credit bureaus, as in the case of Capital One and Discover small-business cards, then the effect can be positive or negative: If you make your payments on time and have a low credit utilization ratio (ideally less than 30%), then the account could improve your credit scores. But if you miss payments and accrue substantial debt, it could drag down your scores.
Your personal liability
Regardless of whether your small-business card reports to the credit bureaus, the personal guarantee still applies: Even if your small business goes out of business, you will still be responsible for paying off the card.
Card issuers often spell out these rules in the terms and conditions that come with the card. Before signing up for a card, you can read through the terms and conditions and look for terms like “personally responsible” and “liable” to see just what you’re signing up for.Capital One® Spark® Cash for Business card, for example, says in the terms and conditions that the cardholder agrees “to be individually, jointly and severally liable for all charges.”
Exceptions to the ruleBrex Card for Startups, for example, is a corporate card for startups that doesn’t require an SSN or a personal guarantee. Instead, it evaluates creditworthiness based on things like the company’s cash flow and spending patterns. It also requires a bank balance of $100,000 to qualify.
In general, though, corporate cards — where the company is on the hook for the debt and not the individual cardholder — are available for businesses with established credit histories, not for new businesses or very small businesses.
If you just opened up shop or are running a one- or two-person business, it will be difficult to find a small-business credit card that doesn’t require your Social Security number along with your EIN.
