Finding a delivery notice in your mailbox can cause some apprehension. The inability to immediately know the sender or the content of the communication leaves room for doubt and worry. However, certain clues can help us decipher the nature of the registered letter even before going to the post office. Among these, the numeric code on the notice is the most important element. In this comprehensive guide, we will analyze in detail the meaning of registered mail code 77, a number that signals communications of some importance.
Understanding the registered mail coding system is the first step to facing the receipt of a notice with greater peace of mind. Each code is not random but follows a precise logic that allows for the identification of the shipment type and, in many cases, to make a good guess about the nature of the sender. Knowing what to expect allows you to prepare adequately, whether it’s a simple communication or an official document that requires prompt action.
Deciphering the Registered Mail Code: The First Clues
Before focusing on code 77, it’s helpful to understand how registered mail codes work in general. Each delivery notice has a barcode and a 10-12 digit numerical sequence. The first two or three digits of this sequence are crucial: they function as an identifier for the type of mailing. This system, while not revealing the exact name of the sender, significantly narrows down the possibilities, distinguishing between a private communication, a bank notification, or a document from a public entity.
Another visual clue, though less common today, is the color of the delivery notice. Traditionally, a white card indicated an ordinary communication, while a green one was reserved for legal documents. Although a white receipt similar to a commercial one is predominantly used today, the combination of the color (if present) and, above all, the initial digits of the code, offers a valuable key to interpreting the incoming message.
The Meaning of Registered Mail Code 77
A registered mail code starting with the digit 7, and particularly the series from 75 to 79, is associated with communications of a legal and fiscal nature. Code 77 falls squarely into this category, signaling an almost certain likelihood that the envelope’s content is a legal document or an important communication from a taxing authority. Ignoring a notice with this code is strongly discouraged, as the notification is considered complete even if not collected, with all the legal consequences that follow.
Specifically, a registered letter identified by code 77 may contain a traffic ticket for a violation of the Highway Code, a document served by a court (such as a summons or a decree), or a communication from the Italian Revenue Agency. These are therefore documents that require attention and, often, action from the recipient within specific deadlines. Recognizing the code allows you to act promptly, avoiding delays that could complicate the situation.
Who is the Sender of a Registered Letter with Code 77
Precisely identifying the sender is the next step. If the notice shows code 77, the most likely senders belong to two main categories: public administration bodies and judicial authorities.
- Italian Revenue Agency: One of the most concrete possibilities is that the communication comes from the tax authority. It could be a tax assessment notice for checks on your tax return, a request for documents, or a tax settlement. In these cases, it is essential to read the content carefully to understand the request and meet the indicated deadlines.
- Legal documents and fines: Code 77 is frequently used for serving traffic tickets. In addition, it can carry actual legal documents, such as an order issued by a civil or criminal court. An example could be a summons to appear as a witness or an injunction.
- Other public entities: Although less frequent for this specific code, it cannot be ruled out that the sender may be another public body, such as a municipality for local tax matters.
How to Act When Receiving a Notice with Code 77
Once you find a delivery notice with code 77, it’s important not to get anxious and to follow an orderly procedure. The first rule is do not ignore the notice. The law stipulates that, after a 30-day holding period at the post office (which extends to 180 days for legal documents), the communication is considered legally served through “compiuta giacenza” (completion of storage) and is returned to the sender.
The next step is to go to the post office indicated on the notice, bringing a valid ID and the notice itself, to collect the envelope. Only by reading the content will you be certain about the nature of the communication and what to do. If it is a complex document or a payment request, it may be useful to consult a professional, such as a lawyer or an accountant, for qualified assistance.
Differences from Other Common Codes
To better understand the importance of code 77, it can be useful to compare it with other frequently used registered mail codes. For example:
- Codes 12, 13, 14, 15: Identify a simple registered letter, often sent by private individuals, companies, or for communications that are not urgent or have no legal value.
- Codes 613, 615: Are often associated with communications from the Italian Revenue Agency, but can also relate to notifications of fines or taxes to be paid.
- Codes 670, 671, 689: Typically indicate a tax bill sent by the Agenzia delle Entrate-Riscossione (formerly Equitalia).
- Code 665: Is a generic code, often linked to communications from insurance companies, banks, or payment reminders.
- Code 783: Like other codes starting with 78, it is often related to fines, legal documents, or communications from the Italian Revenue Agency.
- Code 785: Also falls into the category of legal or tax documents, with a meaning very similar to that of codes 77 and 78.
This distinction highlights how the 75-79 code family, to which 77 belongs, is reserved for official communications that deserve prompt and adequate attention from the recipient.

Far from being just a number, it represents a key to anticipating the nature of an important notification, allowing citizens not to be caught off guard. Knowing its meaning, possible senders, and the actions to take is an example of how information can transform a moment of uncertainty into an opportunity to manage one’s legal and administrative matters with awareness and timeliness.

Frequently Asked Questions

Registered mail code 77, along with similar codes like 75, 76, 78, and 79, almost always identifies an important legal or administrative communication. Very often, it is a legal document, such as a notice served by a court, or a fine for a traffic violation. It can also be an official communication from the Italian Revenue Agency, for example, a tax assessment notice or a check on a tax return. In short, it is a code that requires immediate attention.
The most frequent senders for a registered letter with code 77 are public entities. Among these, the most common are the Italian Revenue Agency (for tax assessments), local police departments or other law enforcement agencies (for serving fines), and judicial system bodies such as courts (for summonses or other orders). Other public administration entities may also use this code for formal communications.
Not collecting a registered letter with code 77 does not stop its legal effects. The law provides for the “compiuta giacenza” (completion of storage) mechanism. For legal documents, the notification is considered complete 10 days after it is deposited at the post office, even if you do not collect the envelope. For other communications, the term is 30 days. Once this period has passed, the document produces all its effects (for example, the deadlines for paying a fine or filing an appeal begin to run), as if it had been duly delivered.
While code 77 is strongly associated with legal documents and fines, other codes identify different types of communications. For example, codes 670 or 671 specifically indicate a payment notice from the Agenzia delle Entrate-Riscossione (formerly Equitalia). Code 618, on the other hand, is more generic and can relate to communications from banks, insurance companies, lawyers, utility payment reminders, or a vehicle recall from the manufacturer.
The first thing to do is to go to the post office indicated on the notice as soon as possible, bringing the notice itself and a valid ID for collection. Given the importance of communications associated with code 77, it is crucial not to ignore the notice. Once you have collected the registered letter, read its contents carefully, paying particular attention to any deadlines for payments or for filing an appeal. If the content is complex, such as a legal document, it is advisable to consult a professional.
