Has it ever happened to you? You are there, in front of the Postamat ATM, ready to withdraw cash or make a payment, and suddenly the message no one ever wants to read appears: “Operation not permitted” or “Card blocked”. Your heart skips a beat, your mind starts racing, and you ask yourself: “Now what?”. Relax, you are in the right place. Having a blocked Postamat is a frustrating experience, but it is almost always solvable.
I have seen this situation dozens of times and I can assure you that, in most cases, the solution is simpler than you think. In this complete guide, I will take you by the hand and explain step by step the most common causes of the block, how to identify the problem, and, above all, how to act to unlock your Postamat in the shortest time possible. We will address every scenario, from a simple incorrect PIN to more complex security issues, providing you with all the information and practical tips to get back to using your card without stress.

Why Was My Postamat Blocked? The Main Causes
Understanding the cause of the block is the first step to finding the solution. The reasons can be various, some depending on a small distraction of ours, others on automatic security mechanisms activated by Poste Italiane to protect us. Let’s look at the most common ones together.
- PIN Entered Incorrectly 3 Times: This is the most classic cause. To protect you from fraud attempts, after the third incorrect entry of the PIN code, the system blocks the card as a precaution.
- Expired or Damaged Card: Every card has an expiration date printed on the front. Once that date is passed, the card stops working. Similarly, a physically damaged card (for example, with a scratched microchip or a ruined magnetic stripe) might no longer be readable by the machines.
- Security Block for Suspicious Operations: The bank constantly monitors transactions. If it detects activity that is anomalous compared to your habits – such as a withdrawal of a very high amount, several close purchase attempts, or an operation from a foreign country where you have never been – it might block the card as a precaution to prevent fraud.
- Insufficient Funds on BancoPosta Account: Being a debit card, the Postamat draws directly from the funds present in your BancoPosta current account. If the balance is not sufficient to cover the amount of a withdrawal or payment, the operation is denied. In some cases, repeated attempts with insufficient funds can lead to a temporary block.
- Report of Theft or Loss: If you have previously reported the card as lost or stolen, it is permanently blocked and cannot be reactivated.
- Technical Problems: Sometimes, the fault lies neither with you nor with the bank. A temporary malfunction of the ATM or the payment circuit can cause the operation to be refused, making you think the card is blocked.
How to Understand the Reason for the Block?

Before panicking, try to gather some clues. The system often helps you understand what is happening.
- Read the Message on the Screen: The ATM often provides a specific error message. “Incorrect PIN”, “Expired card”, or “Contact your institution” are valuable indications.
- Check SMS and App Notifications: If the block is for security reasons, it is very likely that Poste Italiane has sent you an SMS or a push notification on the BancoPosta or Postepay App, alerting you to suspicious activity and providing instructions on how to proceed.
- Check Card Status in the App: Log in to your app and check the status of your debit card. Often you can see if it is active, temporarily blocked, or if there are specific alerts.
The Step-by-Step Procedure to Unlock Your Postamat

Once the most probable cause has been identified, here is how to proceed for each specific scenario.
Case 1: Block due to Incorrect PIN
If you have typed the wrong PIN three times, the block is almost always temporary.
- What to do? In most cases, just wait. The block deactivates automatically after 24 hours. Do not attempt to use the card before this time has passed, otherwise the countdown might restart.
- And if you forgot the PIN? If the problem is that you no longer remember the secret code, do not keep trying. You must request a new PIN. You can usually do this through the personal area of the Poste Italiane website or by going to a post office with a valid ID document.
Case 2: Expired or Damaged Card
If your card has expired, there is no way to unlock it: it must be replaced.
- Expired Card: Poste Italiane normally sends the new card to your residential address a few weeks before the old one expires. If you haven’t received it, contact customer service to check the shipping status.
- Damaged Card: If the card is visibly ruined, scratched, or bent, the only solution is to ask for a replacement. You can do this by going to a post office.
Case 3: Precautionary Block for Suspicious Operations
If you received a block notice for security reasons, it is crucial to act immediately.
- Contact Poste Italiane: Use the channels indicated in the SMS or notification to confirm or disown the suspicious operations. The toll-free number for card blocking is active 24/7.
- Understand the difference between blocking and suspension: Sometimes the card is only suspended pending your confirmation. To learn more, you can read our guide on the difference between credit card blocking and suspension, whose general principles also apply to debit cards.
Case 4: Block due to Insufficient Funds
This is more of a “block” of the operation than of the card itself.
- What to do? The solution is simple: check the balance of your BancoPosta account and, if necessary, make a deposit to have the necessary funds. Once the balance is sufficient, you will be able to use the card without problems.
Useful Contacts: Who to Call to Unlock the Postamat
Having the right numbers at hand is fundamental. Save them in your address book.
- Toll-Free Number for Card Blocking (from Italy): 800.00.33.22 (active 24 hours a day, 7 days a week). This is the first number to call in case of a block due to suspected fraud, theft, or loss.
- Number for Card Blocking (from Abroad): +39.06.45.26.33.22
- Post Office: For issues requiring in-person identification, such as requesting a new card due to damage or loss of the PIN, going to the nearest post office is the best solution.
Prevention: Practical Tips to Avoid Postamat Blocking
Prevention is better than cure. With a few small precautions, you can drastically reduce the risk of finding yourself with a blocked card.
- Memorize the PIN: Avoid writing it on slips of paper or, worse still, on the card itself. If you are afraid of forgetting it, use a secure password manager on your smartphone.
- Check the Expiration: Take a look at your card’s expiration date every now and then. If it is approaching and you haven’t received the new one yet, contact Poste.
- Notify Before Traveling: If you plan a trip abroad, communicate the dates and destination to Poste Italiane via customer service or the app. This will prevent your transactions abroad from being interpreted as suspicious.
- Monitor the Account: Regularly check the movements and balance of your account via the app or website. This helps you both keep your finances under control and notice any anomalies immediately. To learn more about how ATMs work, read our complete guide on ATMs: everything you need to know.

Having a blocked Postamat can be a nuisance, but it is rarely an unsolvable problem. As we have seen, in most cases it is a security measure designed to protect you or a distraction that is easily remedied. The key is to stay calm, act methodically, and, above all, plan ahead.
Conscious management of your card and PIN, combined with constant monitoring of expenses and proactive communication with the bank (especially before a trip), constitutes the best insurance policy against this type of inconvenience.
