Receiving a delivery notice in your mailbox can cause some apprehension. The inability to immediately know the sender and the content of the communication leaves room for doubt and worry. When the notice says CMP Venezia, it’s helpful to know that this is not the original sender, but the logistics center that processed the shipment. This article provides a complete guide to interpreting the most common codes associated with registered mail handled by the Venice Postal Mechanization Center, helping you identify the nature of the communication before you even go to the post office.
Understanding the meaning of the codes on the delivery notice is the first step to handling the situation calmly. These numeric codes, in fact, follow a precise logic that allows you to distinguish a simple communication from a legal document or a payment notice. Knowing this information in advance allows you to prepare adequately and better manage your daily affairs, turning a moment of uncertainty into a conscious and informed action.
What is CMP Venice
The CMP in Venice is one of Poste Italiane’s main Postal Mechanization Centers. Located in Tessera, near Marco Polo Airport, this large facility plays a crucial role in postal logistics for Northeast Italy. Its function is to receive, sort, and route enormous volumes of mail, including packages, letters, and, above all, registered mail, using advanced automated systems. When a delivery notice indicates the origin as “CMP Venezia,” it simply means that your registered mail passed through this center for processing, but the actual sender is another entity, a company, or a private individual.
How to Read the Delivery Notice
The delivery notice is an essential document that provides various pieces of information. Besides indicating that a delivery was attempted, it specifies the post office where you can pick up the shipment and the deadline for doing so (usually 30 days for registered mail and 180 for legal documents). The most important element, however, is the 12-digit barcode. The first two or three digits of this code are crucial for guessing the nature of the content and the sender’s identity. Another clue can be the color of the card: a white notice generally indicates ordinary mail, while a green notice is almost always associated with legal documents or fines.
Deciphering the Most Common Registered Mail Codes
The numeric codes on the delivery notice are the key to unlocking the mystery of the sender. Although there is no absolute certainty until you pick it up, the first few digits offer a very reliable indication. They can be divided into categories to make them easier to interpret and to understand whether it is an urgent communication or a simple letter.
Codes for Legal Documents and Fines

Frequently Asked Questions

The acronym CMP stands for Centro di Meccanizzazione Postale (Postal Mechanization Center). It is a Poste Italiane sorting center where mail is processed and sorted automatically. The words ‘CMP Venezia’ on a notice or envelope simply indicate that your mail was sorted at that specific center. It does not identify the sender, but only a step in the shipment’s logistical journey before reaching its destination.
It is not possible to identify the sender’s name with absolute certainty, but you can get very useful clues. The two elements to check on the delivery notice are the color and the code. A green notice almost always indicates legal documents or fines. A white notice pertains to more general communications. The most important clue, however, is the barcode: the first 2-3 digits (the so-called ‘registered mail code’) identify the type of shipment, allowing you to guess the nature of the content and the sender’s category (e.g., bank, public entity, private individual).
Although there is no fixed rule, some codes are statistically associated with tax communications or penalties. Codes starting with 75, 76, 77, 78, and 79 are typically linked to fines and legal documents. Codes 695, 696, and 697 are often used by the Italian Revenue Agency-Collection for tax bills, such as non-payment of car tax or the Rai license fee. Codes 670, 671, and 689 can also indicate payment notices.
Code 618 is quite generic and is not usually linked to legal documents or tax bills, so the level of concern can be lower compared to other codes. Very often, this code identifies communications from credit institutions (such as the sending of a new credit or debit card), insurance companies, payment reminders for bills, or communications related to a vehicle, such as a recall from the manufacturer. It could also be a formal warning letter sent by a lawyer or a simple communication from a private individual.
Ignoring a delivery notice is not recommended. The registered letter remains available for pickup at the post office for 30 days (the period is longer for legal documents). If it is not collected within this period, the envelope is returned to the sender marked ‘compiuta giacenza’ (holding period completed). By law, the notification is still considered to have been made and produces all its legal effects. This means that any deadlines for payments, appeals, or other actions will begin to run, whether you have collected the communication or not.
