Receiving an undelivered item notice can create doubt and uncertainty, especially when the shipment is at a large logistics hub like the CMP in Milan Roserio. This hub, crucial for the Italian and European postal system, is not a simple post office but an advanced Postal Mechanization Center where millions of packages and letters are processed and sorted. Understanding how it works is the first step to stress-free management of a held shipment, its pickup via authorization, or solving the problem of a non-delivered notice. This guide offers a clear and professional overview to navigate these situations.
The management of mail and packages in a country like Italy, with its dense network of commercial and personal exchanges, is based on a balance between tradition and innovation. The Postal Mechanization Centers embody this synthesis, combining the reliability of traditional postal service with cutting-edge technologies to meet the demands of e-commerce. Dealing with a held item at Milan Roserio means interacting with this complex system. With the right information, every step, from finding the documents to the final pickup, will become a simple and fast operation.
The Role of CMP Milan Roserio in Postal Logistics
The Postal Mechanization Center (CMP) of Milan Roserio is one of Poste Italiane’s most important logistics hubs. Located at Via Cristina Belgioioso 165, this massive center handles the automated sorting of enormous volumes of mail and packages. Every day, millions of items are processed by advanced machinery, such as MPKS sorters, which can sort up to 15,000 packages per hour. Its function is not that of a traditional post office open to the public for all operations, but of a nerve center that directs shipments to their final destinations, whether they are local post offices, other CMPs like the CMP of Milan Borromeo, or international destinations.
A shipment ends up being held at the Roserio CMP mainly when a delivery attempt is unsuccessful and the item needs to be stored pending pickup by the recipient. This often happens with registered mail or packages that require a signature. The center acts as a temporary collection point, ensuring the security of the shipment until it is picked up. The efficiency of this technological hub is essential to support the growth of e-commerce and to ensure the dialogue between the Italian and European markets.
Undelivered Item Notice: The First Step to Pickup
The undelivered item notice is the key document that the mail carrier leaves in the mailbox when a shipment cannot be delivered. This white slip or card contains essential information: it communicates the delivery attempt, indicates the office where the item has been deposited, and specifies the deadline for pickup. It is crucial to pay attention to the address indicated, which could be the Roserio CMP or a local post office. The notice also features a barcode and a numeric code that uniquely identify the shipment, which are essential for tracking and pickup.
The first few numbers of the code can give an idea of the contents. For example, codes beginning with 78, 68, or 61 can indicate judicial acts, tax bills, or general communications, respectively. Knowing the meaning of these codes, as explained in specific guides on undelivered item notice codes, can help you understand the nature of the communication received. In any case, the notice is the key to retrieving your shipment, so it should be kept carefully.
Managing Held Mail at CMP Milan Roserio
Once you receive a notice indicating the Roserio CMP as the pickup location, it is important to act in an organized manner. Proper management of the held mail prevents the shipment from being returned to the sender.
Where and When to Pick Up
The public pickup point at the CMP Milan Roserio is located at Via Cristina Belgioioso 165, 20157 Milan. It is essential to check the opening hours, which are typically Monday to Friday from 7:00 AM to 5:00 PM and Saturday from 7:00 AM to 12:00 PM, closed on Sundays. Before going, it is always advisable to check the information on the undelivered item notice, as there may be specific instructions or changes. Bringing the notice and a valid ID is mandatory to proceed with the pickup.
Holding Periods and Consequences of Non-Pickup
Holding times vary depending on the type of shipment. For standard registered mail, the holding period is 30 days. For packages and other types of mail like Raccomandata 1, the time is reduced to 10-15 days. Judicial acts, on the other hand, are held for a much longer period, up to 6 months. If the shipment is not picked up within these terms, what is known as “compiuta giacenza” (completed holding period) occurs: the item is returned to the sender, and the notification is still considered legally effective. This means that even without physically receiving the communication, it will produce its legal consequences.
Pickup by Authorization: A Practical Solution
When it’s not possible to go in person to pick up a shipment, authorization is an indispensable tool. This procedure allows you to authorize another person to pick up the package or registered mail on your behalf. Most undelivered item notices include a dedicated section on the back to be filled out. This space is for the personal details of the authorizer (the recipient of the shipment) and the delegate (the person authorized for pickup). The authorization must be signed by the authorizer.
To complete the pickup, the authorized person must present three essential documents at the counter:
- The undelivered item notice with the authorization section completed and signed.
- Their own valid identification document.
- A copy of the authorizer’s identification document.
- The undelivered item notice with the authorization section completed and signed.
- Their own valid identification document.
- A copy of the authorizer’s identification document.
This procedure, valid for Poste Italiane and many other couriers, is designed to ensure maximum security and to make sure the shipment is delivered only to authorized individuals. It is a lifesaver for those who are out of town or have unavoidable work commitments.

What to Do if the Notice is Not Delivered or Lost
It can happen that you are waiting for an important shipment and find no undelivered item notice in your mailbox, or that you lose the notice you received. In these cases, all is not lost. The first thing to do is use the shipment’s tracking number, if available. By entering it on the Poste Italiane website, you can check the status of the shipment and find out which post office it is being held at. This information is often sufficient to go to the counter and request pickup.
If you do not have the notice, you can still attempt to pick up the item by going directly to the post office indicated by the tracking (or the one that serves your address) with a valid ID. The postal worker can perform a search using your personal details to locate the shipment. If this attempt also fails, the next step is to contact Poste Italiane’s customer service to open a case and receive assistance. Remember, the absence of the notice complicates the procedure but does not necessarily prevent pickup.

Interaction with a large center like the CMP Milan Roserio generates mixed opinions among users. On one hand, the technological efficiency and the capacity to handle huge volumes are an undeniable advantage in the context of modern logistics. The center represents excellence in automation, which is fundamental for the speed of deliveries in the e-commerce era. Many users report positive experiences with rapid customs clearance and sorting.
On the other hand, there is no shortage of criticism. The most common problems concern packages that appear to be stuck or blocked for days, sometimes weeks, without updates to the tracking. Other users complain about the difficulty of contacting an operator for information and the frustration arising from generic responses or the difficulty of filing an effective complaint. These disadvantages highlight how, despite technological innovation, the aspect of communication and customer support remains a crucial point for improvement to ensure a fully satisfactory service.
