What to Do If You Detect Fraudulent Transactions On UnionBank Credit Card

What to Do If You Detect Fraudulent Transactions on Your UnionBank Credit Card

Imagine this: you’re checking your UnionBank credit card bill and suddenly see a charge you don’t remember making — maybe a purchase from a store you’ve never visited or an online order you didn’t place. Nakakakaba, right?

Credit card fraud can happen to anyone — even first-time users who just started using their cards online. The good news? UnionBank has clear steps to protect you and recover any unauthorized charges. In this guide, we’ll walk you through exactly what to do if you detect a fraudulent transaction, how to secure your card, and what to expect from the investigation process.


āš ļø What Counts as a Fraudulent Transaction?

Before taking action, it’s important to confirm if a transaction is truly fraudulent or just a misunderstanding.

Common examples of fraudulent transactions include:

  • Charges from stores or websites you never used
  • Duplicate charges for a single purchase
  • Purchases made while your card was physically with you
  • Transactions in a different city or country
  • Sudden big-ticket online orders

Sometimes, though, a transaction might look suspicious but isn’t fraud — for example, when a merchant uses a third-party payment processor (so the name on your bill looks unfamiliar).

šŸ‘‰ Tip: Always review your UnionBank Credit Card Statement of Account or check the UnionBank Online app to verify if the charge corresponds to something you actually bought.


🧩 Step-by-Step Guide: What to Do When You Spot a Fraudulent Transaction

🪪 Step 1: Verify the Transaction

Double-check your recent receipts, online subscriptions, and family members who might be authorized card users. A lot of ā€œunknownā€ charges turn out to be:

  • Auto-renewed subscriptions (Netflix, Spotify, etc.)
  • App store purchases by family members
  • Delayed posting of old transactions

Once you’re sure the charge wasn’t yours — proceed to the next step immediately.


šŸ“ž Step 2: Contact the UnionBank Credit Card Hotline

Call UnionBank’s 24/7 Credit Card Hotline as soon as you confirm a suspicious transaction.

Hotline numbers:

  • šŸ“± Within Metro Manila: (02) 841-8600
  • ā˜Žļø Toll-free (outside Metro Manila): 1-800-1888-2277

Tell the agent you’ve detected a potential fraudulent transaction. Be ready to provide:

  • Your full name (as shown on card)
  • The last 4 digits of your card number
  • The transaction amount and date in question

The bank will temporarily block your card to prevent further charges.


🧾 Step 3: Dispute the Transaction

After reporting the issue, you’ll be asked to file a dispute form. You can do this via:

  • UnionBank Online App: Go to Help > Dispute a Transaction
  • Email: The bank may send you a dispute form to fill out and send back

Include all necessary details such as:

  • Transaction date and amount
  • Merchant name
  • Reason for dispute (e.g., ā€œI didn’t make this purchaseā€)

Once submitted, the bank will begin its investigation, which typically takes 30 to 45 days, depending on the case and the merchant’s response.


šŸ’³ Step 4: Request for Card Replacement

UnionBank will usually issue you a new credit card with a different number to ensure your account remains secure. This is free in most fraud cases.

Your old card will be permanently blocked, and any future recurring payments (like subscriptions) will need to be updated with your new card details.


šŸ” Step 5: Monitor Your Account Regularly

After you’ve filed your report, keep monitoring your UnionBank Online account and monthly statements.

  • Enable SMS or email alerts for every transaction.
  • Review your statement line-by-line before paying.
  • Change your online banking password for extra safety.

šŸ”’ How to Prevent Credit Card Fraud in the Future

Preventing fraud is always easier than fixing it. Here are proven ways to secure your UnionBank credit card:

šŸ›ļø 1. Shop Only on Secure Websites

Always check for ā€œhttps://ā€ before entering card details. Avoid random links or ā€œtoo good to be trueā€ promos.

šŸ“² 2. Enable 3D Secure / OTP for Online Purchases

UnionBank uses UnionBank Online Secure (powered by 3D Secure) to send a One-Time Password (OTP) before completing online payments.
This feature ensures that even if someone knows your card number, they can’t complete a purchase without your OTP.

If your card doesn’t prompt OTP verification, call the hotline to activate this feature.

🚫 3. Avoid Sharing Card Details

Never share your card number, CVV, or OTP over text, phone, or social media — even if the message ā€œlooks official.ā€
UnionBank and other legitimate banks will never ask for your OTP.

🧠 4. Check Statements Every Month

Make it a habit to review your monthly statement or UnionBank app regularly. Early detection is the best protection.

🪪 5. Keep Your Card in a Safe Place

If you’re not using it, store it securely. Never lend your card — even to friends or family — unless you fully trust them.
