Why is my bank card declined?

Usually a limit or a check, rarely a disaster.

The answer in 2 lines. Most of the time it is a low balance, a daily spending or cash limit, a wrong PIN entered several times, an online security check that did not go through, or a fraud block by your bank. Open your banking app first: the reason, or an alert asking you to confirm a payment, is often shown there. If you still do not know, call your bank on the number on the back of your card or on 159, never a number from a text or email.

The first 3 steps

Open your banking app: check your balance, limits, alerts and whether the card is frozen.
At the till, try another way to pay: another card, or chip and PIN instead of contactless.
Still stuck? Call your bank on the number on the back of your card, or on 159. Never use a number from a text or email.

The likely causes

Not enough money, or a pending payment has not cleared yet: check your available balance.
Spending or cash limit reached: many banks let you see or change limits in the app.
Contactless declined: your card may ask for your PIN from time to time as a security check. Insert the card and enter your PIN.
Wrong PIN three times: the PIN is usually blocked. Your bank will tell you how to unlock it, often at a cash machine.
Online payment declined: the security check (a code or approval in your app) did not go through. Try again and approve in your app.
Fraud block: an unusual payment or a payment abroad can trigger a block. Your bank may send an alert to confirm it was you.
Card expired, damaged or replaced: check the date and use your newest card.

What not to do

Replying to a text that says "your card is blocked, click here". It is a common scam. Your bank never asks for your PIN or full card details by text.
Trying the same PIN again and again: the third wrong attempt blocks it.

What you can do yourself, and where to stop

In the app: check limits, unfreeze a card you froze yourself, and turn online, abroad or contactless payments on or off when your bank allows it.
You cannot reactivate a card you cancelled as lost or stolen: you need the new card.
If you think it is fraud: block the card and tell your bank straight away (see our guide on lost or stolen cards).

Good to know

The Financial Conduct Authority has removed the single £100 contactless limit and lets banks set their own, so the amount you can pay without a PIN now depends on your bank and settings. Check your app.
If you are struggling with money, your bank has to treat you fairly. Free, impartial help is available from MoneyHelper.

In Bristol, Tom's card is declined at a DIY shop the day after he booked flights. In his app he sees a fraud alert asking whether the flight payment was him. He taps "Yes, it was me", the block is lifted in a minute, and he pays at the till.

A made-up story, for illustration.

Be ready for next time

Before a big purchase or a trip, check your limits in the app.
Carry a second way to pay when travelling.
Note when your card expires: the new one usually arrives a few weeks before.
