Usually it's simple and fixable in minutes.
The answer in 2 lines. Most declines come from a low balance, a daily spending or ATM limit, a fraud hold after an unusual purchase, an expired or locked card, or a typo in the card number, expiration date, security code or ZIP code online. Open your bank's app: alerts and limits usually show there. If you're still stuck, call the number on the back of your card or on the bank's website, never a number from a text message.
The first 3 steps
- Open your bank's or card issuer's app: balance, available credit, alerts, locked card, travel or online settings.
- At the register, try another payment method, or insert the chip instead of tapping.
- Still blocked: call your bank at the number on the back of the card or on its website. Not a number from a text or email.
The usual causes, and the fix
- Not enough money or credit: check your balance or available credit; a pending purchase or a hotel or gas station hold can tie up money for a few days.
- Daily limit reached: debit cards often have daily purchase and ATM limits. Some banks let you raise them temporarily in the app or by phone.
- Fraud hold: a big or unusual purchase, or a purchase in another state or country, can trigger a block. Confirm it through the app or the official number.
- Expired, replaced or locked card: check the date, and check you didn't lock it yourself in the app.
- Online typo: card number, expiration date, security code, or a billing ZIP code that doesn't match your account.
- The merchant's side: a terminal or website problem. Try again later or elsewhere.
What not to do
- Clicking a text that says "your card is blocked, tap here": it's a common scam. Your bank won't ask for your PIN or a one-time code.
- Entering a wrong PIN again and again: the card can get blocked.
Debit cards and overdrafts: why a purchase can be refused
- Under federal rules, your bank can't charge you an overdraft fee on ATM withdrawals and one-time debit card purchases unless you opted in to overdraft coverage.
- If you didn't opt in, a purchase larger than your balance is usually just declined, with no overdraft fee. That's the rule doing its job.
- You can opt in or out at any time. Think it through: overdraft fees can add up fast.
Good to know
- Before a trip or a big purchase, check your limits and travel settings in the app.
- Carry a second way to pay when you travel.
- A replacement card usually arrives before the old one expires: activate it.
In San Antonio, Lucia's debit card is declined at a furniture store the day after she paid for flights. In her app she sees she hit her daily purchase limit. She asks for a temporary increase by phone, using the number on the back of her card, and pays a few minutes later.
A made-up story, for illustration.
Still a problem?
- If you think it's fraud, block the card now (see our guide on lost or stolen cards).
- If your bank won't explain a block or fix an error, you can file a complaint with the Consumer Financial Protection Bureau (CFPB).
- There's no single national daily limit: it depends on your card and bank.
