How many times have you had to contact customer service or participate in a televote, only to be faced with a phone number starting with an unusual prefix? In the telecommunications landscape, not all numbers are created equal. Some are free, while others hide unexpected costs that can turn a simple call into a considerable expense. Knowing the difference between the various types of numbering is the first step to becoming a conscious consumer, capable of using telephone services without fear of nasty surprises on your bill.
This guide was created to clarify the complex world of special numbers in Italy. Together, we will explore the characteristics of toll-free numbers, shared-cost numbers, and premium-rate numbers. You will learn to recognize them by their prefix, understand their cost structure, and, above all, defend yourself against potential traps. Whether you are calling from a landline or a smartphone, the information you find here will provide you with the tools to act with confidence and awareness.

The World of Prefixes: A Map to Navigate By
In the context of telephone communications, the prefix is the key to everything. A simple three-digit number can determine if a call will be free or if it will have a high cost per minute. The main categories into which these special numbers are divided are three: toll-free numbers (like 800 and 803), shared-cost numbers (840 and 848), and the dreaded premium-rate numbers (the 89X family). Each of these families responds to specific cost logic and regulations, designed for different types of services. Learning to distinguish them is fundamental to avoiding unforeseen charges and using every service in an informed manner.
The apparent similarity between these prefixes, which often all start with the digit “8”, can generate confusion. However, the differences are substantial. A toll-free number represents a gesture of courtesy by a company towards its customers, while a premium-rate number is effectively a paid service, the cost of which remunerates the company offering it. Understanding this distinction is not just a matter of saving money, but also of safety, as it allows you to navigate the market with greater mastery.
Toll-Free Numbers (800 and 803): The Free Service Par Excellence

Numbers starting with the prefixes 800 and 803 are universally known as Toll-Free Numbers (Numeri Verdi). Their fundamental characteristic is being totally free for the person making the call. The cost of the call, in fact, is entirely borne by the company or entity providing the number. This service model is a strategic choice for businesses that wish to encourage contact with their customers, offering a direct communication channel without economic barriers. This is the case for many customer support services, public relations offices, and information campaigns.
One of the most frequent questions regards their accessibility from smartphones. It is important to emphasize that calls to toll-free numbers are free from both landlines and mobile networks. However, in some cases, a company may decide to limit access from mobile networks to contain costs, which are higher compared to landline calls. If you receive an error message when trying to call a toll-free number from a mobile phone, the cause is almost always a choice by the number owner and not a problem with your line.
Shared-Cost Numbers (840 and 848): The Middle Ground

Numbers starting with the prefixes 840 and 848 belong to an intermediate category: that of shared cost. As the name suggests, the cost of the call is split between the caller and the recipient. This system allows companies to offer a service at a contained cost for the user, without having to shoulder the entire burden of the call as happens with toll-free numbers. It is a solution often adopted for booking services, such as medical appointments or ticket purchases, where a balance is sought between accessibility and service sustainability.
How Much Do Calls to an 848 Number Really Cost?
The cost structure for those calling a shared-cost number varies based on the prefix and the type of line used. For calls from a landline, 848 numbers involve a charge equivalent to a local call, while for 840 numbers you only pay a connection fee. The situation changes significantly when calling from a mobile phone. In this case, costs are not standardized and depend entirely on your telephone operator’s rate plan, often resulting in higher charges. It is therefore essential to check the conditions of your contract before making the call to avoid surprise costs.
Premium-Rate Numbers (89X): Watch Out for Hidden Costs
Numbers starting with prefixes from the 89X family (such as 892, 894, 895, and 899) are classified as premium-rate or value-added numbers. Calling these numbers has a significant cost for the user, which can be charged per minute or per call (flat rate). These services are designed to directly remunerate the provider. Behind a premium-rate number, entertainment services such as astrology and fortune-telling (typically 899), professional information and assistance services (895), or televoting (894) may be hidden.
The most suitable metaphor is that of a premium service: you pay to obtain specific content. However, a lack of awareness can lead to very expensive bills. Fortunately, consumer protection regulations are strict. The Authority for Communications Guarantees (AGCOM) has established precise rules, such as the obligation of a free initial message informing about the applied rate and the maximum duration of the call, to ensure transparency and avoid telephone scams.
The Jungle of 899 Numbers: Services and Rates
Within the family of premium-rate numbers, the 899 prefixes are perhaps the most well-known and controversial. They are predominantly associated with adult entertainment services, fortune-telling, astrology, and chat lines. Rates can be very high, reaching significant amounts per minute. Precisely because of their nature and associated costs, AGCOM has imposed severe rules: in addition to the informational message on costs, there is a maximum spending cap per single call. Furthermore, by default, many landline operators block these numbers, which can only be unblocked upon the user’s explicit request.
How to Defend Yourself: Tools and Best Practices
The first and most effective form of defense is knowledge. Knowing how to recognize a prefix and associate it with a cost category is the fundamental step to avoiding surprises. Before dialing a number you don’t know, especially if it starts with 8, stop for a moment and check. Another good practice is to always verify the rates, which by law must be clearly indicated on websites or promotional materials of the service you intend to contact. If you have doubts about the identity of who is calling you, you can try to find out who owns a number with online tools.
For even more robust protection, you can act preventively. Contact your telephone operator, both landline and mobile, and ask for a permanent block on calls to premium-rate numbers. This is your right, and the service is free. This simple operation physically prevents your phone from making calls to these expensive destinations, sheltering you from accidental or unauthorized use. Correct call management for outgoing calls is essential for complete control of your telephone spending.
Finally, to counter the broader phenomenon of unwanted calls, such as aggressive telemarketing, a useful tool is the Public Register of Oppositions. By registering your number, you revoke consent for the use of your data for commercial purposes. Although designed primarily for marketing, it contributes to reducing the volume of nuisance calls, increasing control over your line and reducing opportunities for contact with potentially deceptive numbers.
Conclusions

Navigating the world of special phone numbers might seem complicated, but with the right knowledge, it becomes a simple and safe operation. We have seen that the key lies in the prefix: 800 and 803 indicate a service that is always free, 840 and 848 a shared cost with variable rates, while the 89X family hides premium costs that require maximum attention. Remembering these simple rules is the first step to using the phone with peace of mind.
Awareness is your best ally. Always verifying rates before calling and taking advantage of the tools at your disposal, such as the selective blocking offered by operators, will allow you to eliminate any risk. Being an informed consumer not only protects your wallet from unexpected expenses but also gives you the power to choose and use the services you need without any hesitation or fear.
Frequently Asked Questions

Yes, calls to all numbers starting with the prefix 800, and also 803, are always completely free for the caller. This applies to both landlines and mobile networks, regardless of your rate plan. The cost of the call is entirely borne by the company or entity that activated the service.
The main difference lies in the cost allocation. An 848 number is shared-cost: the caller pays a fixed fee, usually equal to the cost of a local call, while the rest of the cost is borne by the recipient. A 199 number, on the other hand, has specific pricing and the cost is entirely borne by the caller; the rate is often higher than a normal call, especially from a mobile, and is not included in the minutes of «all-inclusive» offers.
You can request a free permanent block (selective barring) of calls to all premium-rate numbers, such as 892, 894, and 899. To do this, simply contact your telephone operator, either landline or mobile, and make the request. It is a consumer right to prevent unwanted charges.
No, all emergency and public utility numbers in Italy are always free. Calling the European Emergency Number 112, as well as specific numbers like 113 (Police), 115 (Fire Brigade), 117 (Finance Guard), and 118 (Medical Emergency), has no cost. The call is free from any phone, landline or mobile, even if you have no remaining credit or the SIM is blocked.
If you notice an anomalous charge on your bill or remaining credit for a call to a premium-rate number (e.g., 899), contact your telephone operator immediately to ask for clarification and a cost breakdown. If you believe the charge is not due, you can file a formal complaint with the operator itself. If the problem is not resolved, you can turn to a consumer association or report the issue to AGCOM (Authority for Communications Guarantees).
