This week, the IRS started to send out the second round of stimulus payments, which are part of a larger COVID-relief package that President Donald Trump signed into law. The payments are going out via direct deposit and in the mail, either as a paper check or as an Economic Impact Payment card (or EIP).

When the IRS sent the first stimulus payments, about 4 million Americans received their funds on an EIP card. The IRS said it is using the same debit-card delivery method this time for some of the second stimulus payments in the interest of time. (Here’s how to find out which IRS priority group you’re in for the second payment.)

Below, we answer some common questions about EIP cards, including what to do if you actually get one. We recently updated this story.

What’s an EIP card?

An economic impact payment card is a prepaid debit card that the Treasury Department used to distribute some stimulus payments under the CARES Act, instead of an electronic monetary transfer or paper check. The cards were provided to some eligible US residents for whom the government didn’t have banking information.

The IRS said it will use the cards to distribute stimulus payments this time too.

These Visa debit cards can be used to make purchases, get cash from in-network ATMs and transfer funds to your personal bank account without a fee.

If you’re sent one, after the card arrives, head to the EIP card website to activate it and learn more about how to use it.

Why would I get the EIP card instead of a paper stimulus check?

For the first round of payments, those who were eligible received the first stimulus payment by EIP card instead of by check if they filed their taxes but the IRS didn’t have their bank account information on hand, and if the tax return was processed by IRS service centers in either Andover, Massachusetts, or Austin, Texas, according to a Treasury press release. It isn’t clear what the significance is of those particular service centers, and the Treasury did not return our request for more information.

For the second round of payments starting to go out this week, the IRS said it will send either paper checks or a debit card in the mail if it doesn’t have banking information on hand. The IRS said some people who received a paper check last time might receive a debit card this time, and some people who received a debit card last time may receive a paper check.

How much stimulus money can be loaded on the EIP card?

Getting your payment via an EIP card wouldn’t change anything about the amount you’d get — it’s just a different format of the same payment.

The amount of money you’re allotted in a second stimulus payment (whether it comes in the form of direct deposit, mailed check or EIP card) depends on your AGI, or adjusted gross income, from your tax filings, along with your filing status (single versus joint) and how many dependents you have. The maximum amount a single taxpayer could get is $1,200.

Here’s how old a dependent has to be to get a separate stimulus payment and the stimulus check situation for older adults, people in the SSDI program, US citizens abroad and people living in US territories.

How long could it take to get my EIP card now that a second stimulus payment is authorized?

When the CARES Act was passed in March, the first EIP cards didn’t start going out until mid-May. But the IRS said it expects to start sending EIP cards in the mail starting Wednesday, Dec. 30.

The IRS said you’ll also be able to track your money (in whatever form it will take) using the same IRS tool you can use to track the status of your stimulus payment, later this week.

How will my EIP card be delivered?

If you’re eligible, the IRS said your EIP card will arrive at the address listed on your last tax return in a white envelope that displays the U.S. Department of the Treasury seal. The card will have the Visa name on the front and the issuing bank, MetaBank(R), N.A., on the back. Information included with the card will explain that this is your Economic Impact Payment.

Because the envelope containing the first EIP card wasn’t clearly marked, some people reportedly threw the letter away without opening it during the first round of stimulus payments. The IRS said for eligible people who don’t receive a direct deposit to watch their mail carefully for the card in the coming weeks.

Note, if you moved, you’ll need to inform the IRS and USPS of your new address.

Can I get direct deposit instead?

If the IRS has your bank account information on hand, it’s more likely you’d get the payment by direct deposit instead of an EIP card. Since the first stimulus checks were sent, there has been greater effort to help people who don’t have bank accounts get one for this purpose. Here are ways you might be able to help get a second check faster.

Will the IRS notify me that an EIP card is coming?

With the first stimulus payments, the IRS sent a letter about your money to your last known address within 15 days after the payment was made. The letter included information on how you got the money (check or direct deposit or EIP card), and how to report it if you didn’t receive the payment. But watch out: There have been a lot of stimulus check scams going around. Visit IRS.gov before giving anyone your information to make sure your letter is legitimate.

What if my EIP card gets lost or destroyed?

With the first cards, if you’ve lost or destroyed your EIP card, you can request a free replacement through MetaBank Customer Service. The replacement fee will be waived the first time. We expect the IRS do to something similar this time.

You don’t need to know your card number to request a replacement. Just call 800-240-8100, and choose the second option from the main menu, according to the IRS website.
