The sooner you spot fraud, the faster your bank can act to protect you. Whether it’s credit card transactions and charges  or bank transactions that you don’t recognise, here, we show you how to spot and report them.

Check your statements


Most people will make quite a lot of payments and transactions in a normal month, so it can be easy for an unusual transaction to slip through unnoticed. It’s really important to check your statements regularly and if you see an unauthorised  transaction, report it to your bank straight away.


Check your account at any time with our Mobile Banking app 

With our secure Mobile Banking app, you can check your account at any time. Reviewing your statements regularly helps you keep track of your spending, but you’ll also notice anything that looks suspicious. 

App available to Online Banking customers with a UK or international mobile number in specific countries

Statement codes 

Every transaction on your statement will be listed next to a code – so you can work out how each payment was made. For example, if it says ‘ATM’ that refers to a cash machine. Think; did you use a cash machine on that day, at that time?

Statement references 

This is our list of the codes you’ll find next to the transactions on your statements. Whenever you think you’ve found an unusual transaction, use this table to find out how the payment/withdrawal was made. And if you come across a code you can’t identify, always speak to your bank.

Keep an eye out, on and offline

If you get paper bank statements, make sure you you’ve received all of them. Missing bank statements could be a sign that a fraudster has managed to get your post or had it sent to another address. This is easier in a block of flats or shared accommodation.

You might also receive a paper bill for something you didn’t buy, or from a company you don’t use. If this happens, report it immediately.  


Check your credit report


A copy of your credit report from a credit reference agency will show you the applications for credit that have been made in your name. You’ll be able to spot any applications that weren’t made by you, ask for them to be removed and follow up with your bank or lender.


Ruling out things that aren’t fraud 


If you have a joint credit card or bank account with your partner or spouse, they could have made the payment. Check in with them and see if they bought something and forgot to tell you.

Your available funds vs. your balance

Depending on your bank and where you shop, there can be a delay in how often your balance is updated. 


When you buy something in a shop, your available funds will be reduced by the price of the item. But your balance won’t change until the retailer claims the funds from your account (which can take up to five days). 


If you have pending payments or transactions, it could look like fraud. 

Have you forgotten an automatic payment?

Double check whether the transaction is a standing order or direct debit because it could be one of your regular payments. You might usually be on top of what’s going in and out of your accounts, is this one that’s slipped your mind?


Also, if your payment is due to be made on Monday, you might see your balance and available funds go down on the Saturday morning before

Spending abroad might have extra charges

Have you been on holiday recently? Sometimes spending overseas comes with additional conversion charges. Always spend in local currency to minimise these.

Watch out for free trials 

Some companies will automatically start taking the monthly free from your account when the free trial period for their service. When you sign up for a free trial, put a reminder in your calendar to cancel it if you decide you don’t want to continue.

Common retailers and trading names

Sometimes companies trade under different names. This means something you bought might show up on your statement with a different name to the one you’re expecting. It can be frightening as it can look a lot like fraud. 


We’ve put together a list of companies and their trading names. Check your unrecognised transaction against these common retailers.

Tell your bank immediately if you think you’ve spotted fraud on your bank account


Call your bank’s official fraud number straight away. NatWest customers can visit this page for all the information on reporting a fraud.
