Receiving a delivery attempt notice can cause some apprehension. Not knowing who the sender is or what the communication contains leaves room for doubt and questions.

This article serves as a clear and comprehensive guide to interpreting the codes on delivery notices from the Ancona Postal Mechanization Center, helping you identify the nature of the communication and, with a high degree of accuracy, the sender.
Understanding these codes is not just a way to satisfy curiosity, but a fundamental step in managing your communications consciously and promptly. Whether it’s a simple letter, a legal document, or a bank communication, knowing what to expect allows you to act appropriately, respecting deadlines and legal obligations.
What is the Ancona CMP and What is its Role
The CMP, an acronym for Centro di Meccanizzazione Postale (Postal Mechanization Center), is a strategic facility in the Poste Italiane logistics network. These centers are dedicated to the automated sorting and routing of enormous volumes of mail and parcels. The Ancona CMP, strategically located in Strada di Passo Varano, is the hub for mail management in the Marche region and parts of neighboring regions. Its function is to receive mail collected in the area, process it using advanced machinery called CFSM (Compact Flat Sorting Machine), and direct it to the correct destination post offices for final delivery. This process optimizes delivery times and ensures the efficiency of the postal service on a national scale.
The Delivery Attempt Notice: The First Clue
When the mail carrier is unable to deliver a registered letter or another type of mail that requires a signature, they leave a “delivery attempt notice” in the mailbox. This small slip, either white or green, is the first and most important clue available. It contains essential information: the date of the delivery attempt, the post office where the shipment is waiting to be picked up, and, most importantly, a barcode with a 12-digit identification number. It is the first 2-3 digits of this code that reveal the nature of the communication. If the delivery notice is lost, it’s important to know that there are procedures to retrieve the shipment, as explained in our guide to retrieving a shipment with a lost notice.
Deciphering the Codes on the Delivery Notice from Ancona
The numeric codes on the delivery notice are the key to anticipating the envelope’s contents. Although they don’t provide absolute certainty, they offer a very reliable indication. Here is a breakdown of the most common codes you might find on a notice from the Ancona CMP.
Codes for Legal Documents and Fines (78 Series)
Codes starting with the digits 78 are those that require the most attention, as they almost always refer to legal documents, fines, or communications from public authorities.
- Codes 786 and 787: These codes typically identify legal documents such as summonses, court orders, judgments, or pre-trial detention notices. They can also signal traffic tickets or important tax communications, such as IMU or TARI tax assessments. For more details, you can consult our detailed guide on code 786.
- Code 788: Similar to the previous ones, this code is often associated with notifications of fines, tax payment notices, or other legal documents sent via Poste Italiane. In some cases, it may be a communication from the Italian Revenue Agency.

Codes for Private and Banking Communications (1 and 6 Series)
Not all registered letters contain bad news. Many are simple communications from private individuals, banks, or other companies.
- Codes 12, 13, 14, 15: Identify a standard registered letter, often sent by a private individual, a lawyer, or a company for general communications.
- Code 618: This code refers to a registered letter from a private sender. It could be a communication from a banking or financial institution, an employer, an insurance company, or even a car recall from the manufacturer.
- Codes 612, 614, 649, 669: Are often used for communications from banks, credit institutions, or Poste Italiane itself for sending new credit/debit cards or other contractual notifications.
How to Try to Identify the Sender
Besides deciphering the codes, there are other methods to try to identify the sender before going to the post office. The first step is to use the “Dovequando” tracking service on the Poste Italiane website. By entering the 12-digit code from the delivery notice, the system will not reveal the sender’s name for privacy reasons, but it will show the shipment’s origin location. This, combined with the code’s interpretation, can provide a decisive clue. For example, a registered letter with code 618 originating from your bank’s city strengthens the hypothesis of a bank communication. It is also always useful to think about any upcoming deadlines, existing contracts, or recent online purchases.
The Ancona CMP in the Context of the European and Mediterranean Market
The role of the Ancona CMP is not limited to managing local mail. The city of Ancona, with its important port on the Adriatic Sea, has for centuries been a bridge between Italy, the Balkans, and the Eastern Mediterranean. In a globalized world dominated by e-commerce, the Postal Mechanization Center assumes a strategic importance that extends beyond national borders. It functions as a crucial logistics node for goods and parcels traveling between the European single market and the emerging economies of the Adriatic coast. This function integrates the port’s historical vocation with the innovative needs of modern logistics, making the CMP a key player in the transnational economic and commercial fabric.
Tradition and Innovation in Postal Logistics
The activity of the Ancona CMP is a perfect example of how tradition and innovation can merge. On one hand, it is part of the long history of the postal service, an institution that has united Italian communities for generations. On the other, it represents the cutting edge of technological innovation at Poste Italiane, a company that has transformed from a simple postal service provider to an integrated logistics operator. The high automation of sorting processes allows for the management of previously unimaginable volumes with speed and efficiency, meeting the growing demands of online commerce while ensuring the capillary reach of a service that reaches every corner of the country. Managing complex issues, such as those related to stuck parcels, is a constant challenge that drives continuous improvement, as also happens in other major hubs like the Fiumicino CMP.
