Yes, you can use another credit card after fraud, but the priority is securing the account and finding how the compromise happened. Replacing the card is not a risk-free reset: protect the email, banking login and identity data that a fraudster may have used.

If fraud has occurred, contact the card issuer immediately and check your credit files for accounts you did not open.

Replacing the card is useful, but the card may not be the root problem

A compromised card number can be replaced. A compromised email account, password or identity record is more serious because those details can be used to attack multiple financial relationships. The Financial Ombudsman describes identity theft as including cases where someone steals identity information to obtain goods, services or borrowing in another person’s name.

So the question “should I ever have another credit card?” should be separated from “what allowed the fraud to happen?” If the issuer cancelled the old card and the underlying email or online-account problem remains open, a new piece of plastic does not solve the cause.

What to do immediately after fraud

Contact the card issuer using a trusted number or the official app.
Report every transaction you did not authorise and ask what protection applies.
Change compromised passwords, beginning with the email account that can reset other accounts.
Enable multi-factor authentication where available.
Check bank and card statements for other unfamiliar activity.
Check your credit reports for accounts or searches you do not recognise.

The FCA has previously reviewed how firms handle unauthorised transactions and notes that consumers are protected by relevant rules concerning fraudulent or unauthorised payments. The Financial Ombudsman can investigate complaints about how a regulated financial business handled unauthorised transactions or identity theft.

When getting another card can be sensible

A new card can still be useful if you want a separate account, rewards, travel functionality or the purchase protection associated with credit. MoneyHelper explains that Section 75 can provide legal protection for qualifying credit-card purchases costing more than £100 and up to £30,000, subject to the statutory conditions.

Fraud risk exists on both debit and credit payment methods. Avoiding every credit card does not mean you avoid online payments or account-security issues. Good security controls around the accounts and devices you use matter more than the brand printed on the card.

What Section 75 does not cover

Section 75 is protection against certain problems with goods and services, such as non-delivery, breach of contract or misrepresentation. It is not a blanket promise that every fraudulent transaction will be repaid under Section 75.

For an unauthorised transaction, start with the card issuer’s fraud process. If the complaint is rejected or mishandled, the Financial Ombudsman route may apply. Keep all the evidence, including dates, messages, fraud reports and the issuer’s final response.

If new accounts were opened in your name

This is more than a stolen card. Citizens Advice describes new accounts opened using your identity as identity theft and recommends contacting the bank immediately, keeping records of the case, and contacting the main credit reference agencies to identify and challenge accounts you did not apply for.

Check all three major UK credit-reference files if necessary because different lenders report to different agencies. You do not need to wait for a new application to discover fraud; looking at the files after an incident can reveal related activity.

Secure the layers around the card

If an email account was involved, change the email password and recovery details first. Review forwarding rules and logged-in sessions if your provider supports it. Then update banking passwords and confirm multi-factor authentication is enabled.

Use unique passwords for important accounts and avoid reusing the email password on banking or shopping sites.

Will a new credit card hurt the credit report?

A new application normally creates a hard search, and the new account can appear on the credit file. That is different from the fraud investigation itself. If you are applying soon after an identity-theft incident, make sure the credit report is clean enough that a new application is not mixed up with accounts created by the fraudster.

Do not make a string of applications just to test which card will accept you. Use eligibility checkers where available before submitting a full application.

The safer way to decide

Ask three questions: has the original fraud been contained, is the email and identity layer secure, and do you actually have a reason to hold another credit card? If the first two answers are no, delay the application. If the answers are yes and the card serves a genuine purpose, there is no general rule that a fraud victim must permanently avoid credit cards.

When the incident is bigger than one card

If you discover multiple unauthorised credit applications, debt-collection letters for debts you do not recognise or an account takeover, treat it as an identity-theft case rather than a simple card replacement. Citizens Advice, the Financial Ombudsman and the relevant credit-reference agencies can help you challenge the records and resolve the complaint.

Worked example

Example: a fraudulent card account appears after an email compromise. Suppose a cardholder discovers a £180 purchase they did not make and also finds that another card account was opened in their name. The first step is not a new card application; it is a fraud report to the existing issuer.

The issuer is asked to investigate the £180 transaction, while the customer changes the email password, enables multi-factor authentication and checks credit files for other accounts. That separates the payment dispute from the identity-security work.

Once the account compromise is understood and the fraudulent account has been challenged, the customer can decide whether another credit card is useful. A new card may restore ordinary credit-card functionality, but it does not undo the underlying identity risks unless those risks have been fixed.

Is it safe to get another credit card after fraud?#

It can be safe once the original compromise has been contained, but replacing the card is only one part of the fix. Secure the email account, banking credentials and identity information involved in the incident before taking a new credit account. A new account is safest once the compromised credentials and any fraudulent applications have been dealt with.

What if a fraudster opened credit cards in my name?#

Treat that as possible identity theft rather than just a stolen card number. Contact each affected lender, preserve the evidence and check your credit-reference files for accounts or searches you did not authorise so those records can be challenged. That check can reveal related borrowing that would otherwise remain separate from the original card dispute.

Does replacing a credit card stop fraud?#

Replacing the card normally invalidates the old card details, which helps against further transactions using that number. It does not necessarily stop fraud if the attacker still controls your email, online banking, device, phone number or other identity information. Card replacement solves the exposed number, not an attacker’s continued access to the account behind it.

Does Section 75 cover a hacked credit card?#

Section 75 is not a general hacked-card refund rule. It covers qualifying credit transactions where the supplier has breached the contract or misrepresented the goods or services, while an unauthorised transaction should be reported through the card issuer’s fraud process. The issuer’s fraud route is the starting point for a transaction you say you did not authorise.

Will applying for a new credit card after fraud hurt my credit score?#

A full credit-card application normally creates a hard search and the new account can appear on your credit file. The fraud investigation itself is different, so check your reports first to separate genuine applications from fraudulent searches or accounts. That makes the timing and reason for the application different from a fraud investigation already on the file.

How do I protect my email after card fraud?#

Change the email password to a unique one and enable multi-factor authentication where available. Also review recovery details and logged-in sessions, because control of an email account can let an attacker reset financial-account passwords. Email security is especially important because password-reset messages for financial accounts may pass through the same inbox.

Can the Financial Ombudsman help if my bank mishandles card fraud?#

Yes. The Financial Ombudsman Service can consider complaints about how a regulated financial business handled unauthorised payments or identity theft. Usually you complain to the firm first, keep the evidence and then use the Ombudsman route if the complaint remains unresolved. Keep the lender’s final response because it can be needed if you escalate the complaint.
