Tips to avoid your credit card purchases from being declined

How to avoid the embarrassment and inconvenience of having your credit card purchases declined.

In the early days of credit cards people often only used them for the occasional one-off big purchase like a holiday, or maybe even a new television. Today it is more common for people to use their credit cards instead of cash, and for transactions as small as fuel purchases, or a weekend takeaway.

At some point in your life you will go through the slightly embarrassing experience of having a card transaction declined. If this happens locally, and you have another method of payment, it will an inconvenience and nothing more. However, if you are in a foreign country, and only have your credit card on you as a method of payment you could have a real problem.

Use this guide to discover why your credit card transaction may have been declined and what you can do to avoid rejected purchases in the future.

Why was my credit card transaction declined?

To be certain of the exact reason your credit card transaction was declined, you need to speak to your credit card company. However, these are some of the common causes:

  • Odd spending pattern

If your card provider notices strange patterns in your spending habits they may well put a block on your credit card for security purposes. For example, if you only ever use your credit card a couple of times a week for very small purchases, and then in one day there are 3-4 large purchases made, your issuer may flag the activity as strange or potentially fraudulent and will block the card.

  • Daily limit

Some credit cards have daily spending limit within the terms and conditions. If you have not read your terms properly you may not be aware of these and this could result in you overspending and having a transaction declined.

  • Spending abroad

If you're planning to use your credit card overseas, you should contact your card provider to let them know beforehand. If your issuer sees a range of transactions happening overseas, they might suspect it's a fraudulent payment and block your card.

  • EFTPOS offline

EFTPOS machines use the phone network to communicate with the banks to verify and authorise your transactions. If there is a system outage at the point of sale or with the bank's server, the transaction may be declined. If this is the case, you may be asked to sign the tax invoice for authorisation.

  • Exceeded your credit limit.

Every credit card comes with a maximum credit limit that you shouldn't exceed. While some credit cards let you spend beyond the credit limit and will charge you a fee, others will simply decline the transaction if you spend beyond the limit. If you require more credit, you can find out how to increase your credit limit with our guide.

The different codes used to describe why your transaction was declined

Did you know that when your card is declined the EFTPOS machine is sent a code from the bank handling the transaction? These range from incorrect PIN, expired card, suspected fraud and more. These are some examples of response codes from a Commonwealth Bank credit card:

Response CodeMeaning
04Card has been lost - take into possession
55Incorrect PIN
54Expired card

These examples are taken from Commonwealth Bank documentation, keep in mind that these may vary from bank to bank, and different EFTPOS machines at your chosen retailer.

Who to contact when your credit card transaction is declined

If your card is declined, it's still best to get in contact with your bank first to confirm exactly why it was rejected and what you can do to resolve the issue. Use the table below to find the relevant contact details for your credit card issuer.

      Hi Diana,

      Thank you for your inquiry. Please note that you’ve come through to we are an Australian financial comparison website and general information service and we do not represent any credit card company

      Just to confirm, what’s the name of the credit card company that issued your AMEX card? Since we do not have access to your credit card account, you’d be best if you contact your credit card issuer directly so they can advise why your credit card was declined.

      Hi M E, thanks for your inquiry!

      To access a credit account you will need an eligible credit card. It would be best to contact your bank directly to access your credit account.

    My westpac debit card said declined but i had my pay in there. Could it be due to my account was overdrawn for 2 weeks but its now in credit? How do i use my card now?

      Hi Amanda,

      Thanks for your question.

      You might want to log in to your Internet banking account and check you had sufficient funds to make the transaction. If your account was overdrawn you were likely charged fees (Westpac charges $9) which may have taken more funds out of your account than you realised. If your account was in credit and you had sufficient funds to complete the transaction, you might want to get in contact with Westpac directly to discuss why the transaction didn’t go through.

      I hope this has helped.

      Hi Michael

      Thanks for your message and sorry to hear you’ve been having problems.

      Perhaps there was other circumstances in place with the error code 05. Is your card working now?

    Why doesn’t your bank contact you first before they block you card in regards to the odd spending pattern?

      Hi Jason.

      Thanks for your question.

      It’s just a security thing. If you don’t let your bank know about your travel plans, the bank has to be quick to block your account if they suspect a suspicious transaction. The bank or lender wants your funds to be secure so as soon as they sense something odd they block the card right away.

      Let the bank know about your travel plans if you want to stop this from happening to you while you’re overseas.

      I hope this helps.
