Waiting for a package can turn into an odyssey, especially when the tracking gets stuck on a cryptic message: “Processing at the Postal Operations Center.” For many, this phase coincides with a prolonged stop at the Postal Mechanization Center (CMP) in Peschiera Borromeo. This crucial logistics hub, on the outskirts of Milan, handles a huge volume of domestic and international shipments. However, it is often the subject of reports for delays, losses, and difficulties in obtaining information. Understanding the role of this center and knowing the correct procedures for filing a complaint is essential to protect your consumer rights.
This article offers a comprehensive guide to dealing with service issues related to the Peschiera Borromeo CMP. We will analyze the causes of the most common problems and describe, step-by-step, the actions to take to file an effective complaint with Poste Italiane. The different complaint methods, expected response times, and tools available to citizens, such as the conciliation procedure, will be illustrated, should the initial complaint not lead to a satisfactory solution. The goal is to provide a practical tool for navigating a situation that combines tradition, that of the postal service, and innovation, that of global e-commerce, not always in perfect harmony.
The Strategic Role of the Peschiera Borromeo CMP
The Postal Mechanization Center of Peschiera Borromeo is one of the most important logistics hubs in the Poste Italiane network. Imagine it as a gigantic, bustling crossroads where millions of letters and packages converge every day. Its function is to sort mail and shipments, directing them to local distribution centers or to other countries. Thanks to advanced technologies and about 700 employees, the center can process tens of millions of items per year. Its location near Milan makes it a prime entry point for goods from abroad, particularly for online purchases transiting through Lombardy’s airports.
However, this central role also exposes it to critical issues. An exponential increase in volume, linked to the growth of e-commerce, combined with possible internal reorganizations, can create bottlenecks. When a package, especially an international one, is “stuck” or “in processing” at Peschiera Borromeo for an unusually long time, it is likely waiting to be processed, checked, or sorted. Many online testimonials, found on forums and social networks, highlight how stops at this CMP can last from a few days to several weeks, generating frustration and uncertainty for recipients.
Common Causes of Delays and Losses
The service issues involving the Peschiera Borromeo CMP can have various origins. One of the main causes is the enormous traffic volume. The center handles an immense quantity of shipments, and during seasonal peaks like Christmas or Black Friday, congestion is almost inevitable. Added to this are international shipments, which require specific procedures. If a package comes from a non-EU country, it must go through customs checks, a process that can add days, or even weeks, to standard delivery times.
Another long-standing issue, as reported by some sources, concerns work organization and staffing resources, which may not always be sufficient to handle the incoming flows. Problems such as incomplete or incorrect addresses can also further slow down the process, forcing operators to perform manual checks. Finally, the possibility of an actual loss cannot be ruled out. Although rare in percentage terms, in a system that moves millions of items, the risk of a shipment being lost or damaged exists. In these cases, promptly filing a complaint becomes the only way to try to recover the item or obtain compensation.
How to File a Report with Poste Italiane
When a package is stuck or a loss is suspected, it is essential to act in a structured manner. Trying to contact the Peschiera Borromeo CMP directly almost always proves to be a fruitless action. The phone numbers found online are often internal or not dedicated to customer support. The correct procedure involves using the official complaint channels provided by Poste Italiane, which are valid for service issues at any sorting center, including more specific ones like the Bologna CMP.
The party authorized to file the complaint is, first and foremost, the sender, as they are the holder of the shipping contract. However, the recipient or their delegate (such as a consumer association) can also initiate the process. Poste Italiane offers several ways to submit the report:
- Online: This is the fastest method. By accessing the official website, you can fill out a specific form for packages and express courier services, entering all the shipment details.
- Certified E-mail (PEC): By sending a communication to the address reclamiretail@postecert.it, attaching a detailed complaint letter.
- Registered Letter with Acknowledgment of Receipt (Raccomandata A/R): By sending the written complaint to Casella Postale 160, 00144 Roma (RM). This method provides legal value to the communication.
- In-person at a Post Office: You can submit the complaint letter directly at any post office.
Regardless of the chosen channel, it is crucial to provide all possible information: tracking code, dates, description of the contents, and, if available, a copy of the shipping receipt. Poste Italiane commits to providing a response within 45 days of receiving the complaint.
What to Do If the Complaint Is Unsuccessful
If Poste Italiane’s response is delayed beyond the expected 45 days, or if the outcome of the complaint is deemed unsatisfactory, all is not lost. The next step is the conciliation procedure. This is a free tool that allows the dispute to be resolved out of court. The conciliation request can be submitted with the assistance of one of the Consumer Associations that have signed an agreement with Poste Italiane, or independently at a post office. A joint committee will examine the case and formulate a settlement proposal within 60 days. This path is often faster and more effective than legal action.
Should conciliation also fail to lead to a solution, the user has another option: turning to the Italian Communications Authority (AGCOM). AGCOM can be called upon to resolve the dispute, representing the last level of judgment before considering possible legal action. It is important to remember that in case of loss or damage, the customer is entitled to compensation, the amount of which varies depending on the type of shipping service chosen and any insurance taken out. The Poste Italiane Service Charter and the summary of refunds are the reference documents for knowing the amount of compensation provided. Similar problems can also occur at other large centers, as highlighted in our guide to complaints for the Verona CMP.
Handling International Packages and Customs
A particularly frequent cause of delays at the Peschiera Borromeo CMP involves shipments from countries outside the European Union. When a package enters Italy, it is taken over by the International Exchange Center, which often physically coincides with or is closely connected to the CMP. This is where the customs clearance process begins, a phase that depends not only on Poste Italiane but also on the Customs and Monopolies Agency (ADM).
During this phase, the package is inspected to verify its contents, compliance with European regulations, and declared value. If the documentation is incomplete or if the value of the goods exceeds certain thresholds, customs duties and VAT are calculated, which must be paid by the recipient upon delivery. This process can cause prolonged holds, during which the tracking may not show significant updates, simply stating “in processing.” This is a common situation at many hubs, including those in southern Italy, as explained in our analysis of complaints at the Catania CMP. Patience, in these cases, is essential, but a delay exceeding three or four weeks fully justifies filing a formal complaint.

Conclusions

Dealing with a service issue at the Peschiera Borromeo CMP requires patience and a methodical approach. Although the impulse is to seek direct contact, the most effective strategy is to use Poste Italiane’s official complaint channels. Documenting every step, from the tracking number to the completion of the complaint letter, is a crucial step in building a solid case. Remember that the sender is the key figure for initiating the dispute, but the recipient also has tools to make their voice heard. In the face of unusual delays or suspected losses, one should not hesitate to formalize their complaint. If the initial response is inadequate, the conciliation procedures and the intervention of AGCOM offer further levels of protection. In a world where logistics is the bridge between commercial tradition and digital innovation, knowing your rights is the first step to ensuring that bridge always remains crossable.
Frequently Asked Questions

If the online tracking indicates that your package is “in processing” at the Peschiera Borromeo CMP, it means it is at the main Poste Italiane sorting center for that area. The stop can be due to several reasons: normal processing times, waiting to be sorted to the local distribution center, or, especially for international shipments, customs checks. If the stop lasts for many days without updates, there might be a problem, and it is advisable to initiate the reporting procedures.
Although phone numbers and a physical address exist for the Peschiera Borromeo CMP, these are not official channels dedicated to customer support for complaints or information on individual shipments. The correct procedure is to use Poste Italiane’s national support channels, such as the toll-free number 803.160, the online forms on the official website, or by filing a formal complaint.
Poste Italiane commits to responding to complaints within 45 calendar days of their receipt. This deadline is established by AGCom Resolution no. 184/13/CONS. It is essential to keep the receipt or protocol number of the complaint to monitor the case.
If you do not receive a response within 45 days or if the proposed solution is not satisfactory, you can initiate a conciliation procedure. This is an attempt to resolve the dispute amicably with the help of a mediator. If conciliation also does not lead to a positive result, the last option is to turn to the Italian Communications Authority (AGCOM) for a resolution of the dispute, or to consider legal action, especially if the financial damage suffered is significant.
To file an effective complaint, several documents are necessary. Make sure you have the shipping code (tracking number), the complete details of the sender and recipient, a detailed description of the package contents, and, if possible, proof of its value (such as receipts or invoices). In case of damage, it is helpful to attach photographs that clearly show the damage to the packaging and its contents.
