Waiting for a package can turn into a frustrating experience, especially when the online tracking gets stuck on an enigmatic message: “Processing at the Postal Operations Center.” If the location indicated is CMP Milan Roserio, it means your shipment is at one of Poste Italiane’s largest and most important logistics hubs. This hub handles a huge volume of mail and packages, both domestic and international. A slowdown at this stage doesn’t necessarily indicate a problem, but when days go by without updates, it’s natural to worry. This article offers a comprehensive and professional guide to dealing with delays, losses, or damages related to transit through the Milan Roserio center, explaining the official procedures for filing an effective complaint.
Understanding the role of this center is the first step in managing anxiety. Imagine it as an immense arterial system where shipments from all over Italy and the world converge. Here, postal tradition and technological innovation meet to sort millions of items. However, the complexity of such operations can sometimes lead to hitches. Knowing how to navigate these circumstances is crucial to protecting your consumer rights. In the following chapters, we will analyze step-by-step the actions to take, from initial checks to filling out official forms, to resolve the issue as quickly and correctly as possible.
What is the CMP Milan Roserio and Why is Your Package There
The Centro di Meccanizzazione Postale (CMP) of Milan Roserio is one of Poste Italiane’s main sorting infrastructures. It functions as a giant nerve center where packages and letters are received, scanned, automatically sorted, and redirected to their final destination. Its strategic location in northern Italy makes it a mandatory transit point for a large portion of shipments crossing the country, as well as for those coming from or heading to the European and international markets. The presence of your package at Roserio is, therefore, a standard stop on its journey.
The reasons why a shipment might experience a slowdown or a temporary stop at this hub are numerous. Volume peaks, such as during the Christmas holidays or Black Friday, can congest the sorting systems. For international shipments, the hold-up may be due to customs checks, a standard procedure that takes time to verify documentation and contents. Other common causes include damaged or illegible shipping labels, incomplete addresses, or errors in the tracking system. In most cases, it’s a temporary stop before the package resumes its journey.
Delivery Delay: The First Steps to Take
Before filing a formal complaint, it’s important to act methodically. The first step is to carefully monitor the tracking on the Poste Italiane website using the shipping code. Analyze the update history to understand the last recorded status. If the package has been “in processing” for several business days beyond the standard timeframes for the purchased service, then you can start talking about a significant delay. It’s useful to consider that delivery times vary greatly depending on the service (e.g., Posta1, Pacco Celere, registered mail) and the shipment’s origin.
If the delay continues, a preliminary action is to contact Poste Italiane’s customer service at 803.160. Keep the shipping code handy and be ready to provide all the details. Often, an operator may have access to more detailed information than what is visible online and can provide clarification on the situation. This phone call can sometimes resolve the situation or, at the very least, confirm the need to proceed with a formal complaint. At this stage, patience is still a virtue, but gathering information is a strategic move.
How to Officially Report a Delay or Loss
When the delay becomes undeniable or the possibility of a loss arises, it’s time to initiate an official complaint procedure. It’s important to know that the person entitled to file the complaint is the sender, as they are the contractual party for the shipping service. However, the recipient can and should also take action by urging the sender and gathering all necessary documentation. Poste Italiane provides several channels for submitting the report.
The methods for filing a complaint include:
- Online form: On the Poste Italiane website, a digital form is available for packages and express courier services. This is often the fastest and most traceable route.
- Certified E-mail (PEC): Sending the complaint letter to the address reclamiretail@postecert.it gives legal value to the communication.
- Registered Letter with Acknowledgment of Receipt (A/R): A traditional but still valid method. The address is Casella Postale 160, 00144 Rome (RM). Sending a registered letter with acknowledgment of receipt guarantees proof of reception.
- Post Office: You can go in person to a post office and submit the completed form.

Damaged Package: The Correct Procedure to Follow
Receiving a visibly damaged package requires immediate action. At the time of delivery by the courier, it is essential to exercise your right to “accept with reservation”. This phrase, written on the delivery receipt (paper or digital) along with a brief description of the visible damage (e.g., “crushed box,” “wet package”), is an indispensable legal protection. Refusing to sign with reservation can seriously compromise your ability to get a refund. If the damage is very severe, you can also refuse the delivery, stating the reason.
If the damage was not visible from the outside and is only discovered after opening the package (hidden damage), the complaint procedure must be initiated as soon as possible, generally within 8 calendar days of the delivery date. In both cases, photographic documentation is essential. Take clear, detailed photos of the outer packaging before opening it, the inner packaging, and, most importantly, the damaged product. These images will be crucial evidence to attach to the complaint, which will follow the same channels as for a lost package (online form, PEC, registered letter). Attaching proof of the item’s value (receipt, invoice) is also a fundamental step for the refund request.
Timelines and Documents Required for the Complaint
Timeliness is a key factor for a successful complaint. Poste Italiane, like other logistics operators, sets specific deadlines for reporting a service issue. For a delay, the complaint can be filed after the maximum delivery times specified in the Service Charter for that specific shipment have passed. For a lost package, you act when the tracking has not been updated for a prolonged period and customer service provides no solutions. In the case of damage, the timelines are stricter: the reservation must be made immediately upon delivery for obvious damage, while for hidden damage, the deadline is usually 8 days.
For the complaint to be processed correctly, it is essential to attach the required documentation. Prepare a folder, either physical or digital, with the following items:
- Complaint Letter: The official Poste Italiane form, duly completed in all its parts.
- Shipping Code: Proof of shipment (waybill or receipt).
- ID Document: A copy of the claimant’s ID (usually the sender).
- Proof of Value: Invoice, receipt, or a declaration stating the value of the contents, especially for insured shipments.
- Photographic Evidence: In case of damage, photos are essential to prove the extent of the problem.

What to Expect After Filing the Complaint
Once the complaint has been submitted according to official procedures, the waiting period begins. Poste Italiane commits to providing a response within a set maximum timeframe, which for domestic services is 45 calendar days from the date the report is received. During this period, you can monitor the status of your case online, if the procedure was initiated through the website, using the provided identification code. It is advisable to keep all receipts and correspondence, including case numbers and submission dates.
The outcomes of the complaint can vary. In the best-case scenario for a delay, the package is located and put back on track for delivery. In case of a confirmed loss or damage, Poste Italiane may offer a refund. The amount of the refund depends on various factors: if the shipment was insured, its value will be reimbursed up to the maximum coverage amount. For uninsured shipments, a standard compensation is usually granted, calculated based on weight or a fixed amount defined in the Service Charter. If the response is not satisfactory, or if it does not arrive within the specified time, you can initiate a conciliation procedure.

Frequently Asked Questions

If the online tracking shows the package has been stuck at the CMP Milan Roserio for several days, the first thing to do is wait. It is often just a slowdown in the sorting process. If the status doesn’t change after a reasonable period, it is advisable for the *sender* to contact Poste Italiane’s customer service to initiate a report, as they are the holder of the shipping contract. The recipient has limited power to act at this stage.
To report a delay, you must file a formal complaint with Poste Italiane, not directly with the CMP. The complaint can be submitted after the maximum delivery times for the service used have passed. The methods for filing a complaint include filling out the online form on the Poste Italiane website, sending a PEC (Certified E-mail) to reclamiretail@postecert.it, a registered letter with acknowledgment of receipt (A/R) to Casella Postale 160, 00144 Rome (RM), or submitting the form at a post office.
If the package appears damaged upon delivery, it is crucial to accept it *’with reservation’*, specifying the reason on the courier’s receipt (e.g., ‘dented box’). Afterward, document the damage with detailed photographs of the packaging and its contents. Both the sender and the recipient can file a complaint with Poste Italiane, attaching the photographic evidence and shipping documentation, preferably within a few days of receipt.
If the tracking has not been updated for a long time and you suspect the package is lost, the sender must file a claim for loss with Poste Italiane. This can be done via the website, PEC (Certified E-mail), registered letter with acknowledgment of receipt (A/R), or by going to a post office. You will need to provide the shipping code and all relevant details for identifying the package. Any potential refund depends on the type of shipping service purchased and whether it was insured.
No, it is not possible for private citizens to directly contact the Centro di Meccanizzazione Postale (CMP) of Milan Roserio for information about shipments. All communications, assistance requests, and complaints must be handled through Poste Italiane’s official channels: customer service at 803.160, the official website, the app, or by visiting a post office.
