Receiving a delivery attempt notice in your mailbox can cause some apprehension. Not knowing who the sender is or the contents of the registered mail awaiting pickup is a common situation. This is especially true when the communication comes from a large sorting center like the CMP of Milano Borromeo in Peschiera Borromeo, a crucial hub for mail management in northern Italy. Fortunately, you can get a clear idea of the contents even before going to the post office. The numeric codes on the notice are the key to deciphering the nature of the communication, allowing you to distinguish a simple letter from a legal document or a tax collection notice.
Understanding the meaning of these codes is not just a way to ease anxiety, but also a practical tool to prepare yourself properly. Knowing in advance whether it’s a communication from a bank, the Revenue Agency, or a traffic ticket allows you to get organized and, if necessary, consult a professional. This guide offers a comprehensive overview for interpreting the codes on delivery attempt notices processed by CMP Milano Borromeo, turning a moment of uncertainty into clear, manageable information.
The Role of CMP Milano Borromeo
The acronym CMP stands for Centro di Meccanizzazione Postale (Postal Mechanization Center). These are large Poste Italiane facilities where mail is collected, sorted, and forwarded to its final destinations. The Peschiera Borromeo center is one of the most important and technologically advanced in Italy, a true nerve center for millions of letters and packages every day. When the delivery attempt notice mentions “CMP Milano Borromeo,” it simply means that your registered mail passed through this center for automated sorting. This does not identify the sender, but only a stage in the shipment’s logistical journey. Its role is to ensure efficiency and traceability, fundamental elements in a system that combines tradition and innovation.
What Is a Delivery Attempt Notice and How to Read It
The delivery attempt notice is the small slip, usually white or green, that the mail carrier leaves when they cannot deliver registered mail because the recipient is absent. This notice contains essential information: the date of the delivery attempt, the post office where the letter is being held, and the time frame available for pickup (usually 30 days for registered mail and up to 180 days for legal documents). The most important element, however, is the barcode and its associated numerical sequence. The first two or three digits of this code are crucial for identifying the type of communication. The color of the notice itself provides an initial clue: white is used for ordinary communications, while green is reserved for legal documents and fines.
Deciphering the Codes: The Complete Guide
The numeric codes on the delivery attempt notice are the real key to discovering the sender. Although they don’t offer absolute certainty, they provide a very reliable indication. Let’s analyze the main categories to clarify.
Codes Identifying Legal Documents and Fines
Codes starting with the digits 75, 76, 77, 78, and 79 are the ones that require the most attention. These numbers almost always identify legal documents, such as a court order, or fines for traffic violations. Derived codes like 781, 782, 786, and 787 also fall into this category and can indicate payment reminders for taxes like TARI (waste tax) or car tax. In many of these cases, the delivery attempt notice will be green, a further sign of the communication’s legal nature. Knowing this information in advance is useful to avoid being unprepared at pickup and to understand the possible implications of codes like 77.
Codes Related to Banks, Insurance, and Utilities
Another very common category concerns communications from financial institutions, insurance companies, or utility providers. The codes 612, 614, 618, and 665 are often associated with these senders. For example, registered mail with code 618 might contain a new credit or debit card, communications about a bank account, or payment reminders. The code 665 is frequently used for notices regarding traffic accidents, insurance policies, or reminders for unpaid bills. Codes 648, 649, and 669 can also indicate the sending of new cards or communications from your bank.
Codes from the Revenue Agency and INPS
Communications from public entities like the Agenzia delle Entrate (Revenue Agency) or INPS (National Social Security Institute) are identified by specific codes. The codes 670, 671, and 689 are infamously known for being associated with tax bills or tax assessment notices. Code 689, in particular, is often used by the Agenzia delle Entrate-Riscossione (the collection agency) for non-payment of taxes or local levies like IMU (property tax). However, the same code can also be used by INPS for communications regarding pensions or benefits. Codes 63, 65, 630, and 650 are more specifically linked to INPS communications, such as notifications about pension benefits or medical check-ups. It is also important to pay attention to tax communications like those identified by code 673.
Other Common Codes and Their Meanings
Finally, there are more generic codes. Those starting with 12, 13, 14, or 15 usually indicate simple registered mail, sent by a private individual, a company, or a lawyer for communications that are not urgent or serious. Codes 608 and 609 are often used by public administration bodies for sending documents, such as an identity card. Code 616 can be multipurpose, indicating anything from an unpaid car tax to general communications from Poste Italiane. For optimal management, it’s always useful to know the pickup and authorization procedures once you’ve identified the type of communication.
The Mediterranean Context: Tradition and Innovation in Mail
The Italian postal system, with its paper delivery notices and large mechanization centers like the CMP in Peschiera Borromeo, represents a fascinating blend of tradition and innovation. In an increasingly digital world, registered mail retains a legal value and formality that Mediterranean culture, and Italian culture in particular, recognizes and respects. It is a tangible bridge between the citizen and institutions. The technological efficiency of the CMPs, which sort millions of items with robotic precision, is combined with an ancient gesture: the mail carrier leaving a notice in the mailbox. This balance reflects the ability to integrate innovative solutions without uprooting established habits, ensuring that important communications, often with legal and economic implications, maintain a physical, secure, and universally recognized notification channel.
What to Do After Deciphering the Code
Once you have an idea of the sender thanks to the code, the next step is to go to the post office indicated on the notice. It is essential to bring the delivery attempt notice itself and a valid ID. If you cannot go in person, you can authorize someone else. The authorization must be filled out in the designated space on the back of the notice and accompanied by a copy of the authorizer’s ID. The authorized person will need to present both the completed authorization form and their own ID. Adhering to the holding period is crucial: once it expires, the registered mail is returned to the sender marked as “compiuta giacenza” (holding period completed), but its legal effects remain valid, especially for tax or legal documents.
