You receive a call from a number starting with +33 806 and your first instinct is to hang up. This gesture, shared by the majority of users, is based on a persistent confusion between premium-rate numbers and standard-rate numbers. The prefix 0806, displayed in international format with +33, belongs to the category of so-called “grey” or “normalized” numbers, charged at the price of a regular call. Understanding this mechanism helps avoid missing out on legitimate customer service or useful information.
Why the +33 806 format provokes so much distrust
The +33 is not suspicious in itself. It is the international dialing code for France. When your phone displays +33 806 followed by six digits, it simply translates the national number 0806 XX XX XX into universal notation.

The confusion comes from a mix-up. For years, 08 numbers have suffered from a bad collective reputation. The ranges 081, 082, and 089 have been associated with sometimes hefty surcharges, and this image has contaminated the entire 08 range, including numbers that have never been premium-rate.
Many users do not distinguish between a 0806 (standard rate) and a 0899 (premium-rate). The blocking reflex applies indiscriminately. This distrust has a concrete cost: calls from customer service, mutual insurance, or administrations go unanswered, forcing the user to call back, often to another, more expensive number.

To delve deeper into what the number +33 806 means within the framework of the French numbering plan, we must return to the color coding system established by Arcep.
Pricing of 0806 numbers: Arcep’s color code
Arcep (the Regulatory Authority for Electronic Communications, Postal Services, and Press Distribution) has established a color coding system so that each user can identify at a glance the cost of an 08 number.
- Green (0800 to 0805): call and service completely free, regardless of the operator or the duration of the call.
- Grey (0806 to 0809): the call is charged at the standard communication rate, with no additional cost related to the service. The price depends solely on your phone plan.
- Purple (081, 082, 089): premium-rate call. The cost of the service is added to the communication price. It is this range that fuels the general distrust towards 08 numbers.
The number 0806, therefore +33 806 in international format, belongs to the grey range, charged at the price of a local call. If your plan includes unlimited calls to landlines, a call to a 0806 is generally included in this package.
What “non-premium” means in practice
A grey number generates no revenue for the company that provides it. Unlike purple numbers, where part of the bill pays for a service (information, contests, premium technical support), the 0806 charges nothing beyond the cost of transporting the call.
This is precisely why many companies use it for their customer relations. They want to remain reachable without the cost of the call deterring their customers.
Updates to the numbering plan 2023-2026 and impact on 08 numbers
Recent developments in the French numbering plan reinforce the distinction between premium-rate and standard-rate ranges. Arcep has tightened the allocation rules to limit abusive uses, particularly concerning purple ranges.
In this context, the numbers 0806-0809 are positioned as a reliable alternative to premium-rate numbers. The goal is clear: to provide companies with a normal-priced contact channel while restoring users’ trust in 08 numbers.
Distrust persists despite safeguards
Have you ever let a +33 806 call ring without answering? You are not alone. The majority of users still apply a binary filter: “08 = scam”. This reaction, understandable given past abuses, mainly penalizes access to standard-rate customer services.
A common example: a mutual insurance company or a customer service uses a 0806 for its callbacks. The user does not answer, does not call back, and then ends up contacting a short premium-rate number found online. The result is paradoxical: by avoiding a free call, they end up paying more.
Check a +33 806 number before calling back
When a +33 806 number appears in your call log, a few simple checks are enough to decide.
- Convert the number to national format by replacing +33 with 0. The +33 806 XX XX XX becomes 0806 XX XX XX. This manipulation confirms that it is indeed a French grey number.
- Consult the reverse directory of SVA numbers on the surmafacture.fr website, referenced by the Directorate General for Competition. It allows you to check which company an 08 number is assigned to.
- If you receive a text message asking you to call back an 08 number you do not know, report it to 33700, the platform dedicated to combating phone spam.
An incoming call to 0806 cannot generate a surcharge, even if you answer. The surcharge only applies to the ranges 081, 082, and 089, and only for outgoing calls (those you make, not those you receive).
Distinguishing a legitimate call from spam
The fact that a number is in 0806 does not guarantee that the caller is acting in good faith. A telemarketer can use a grey number. The difference lies in the nature of the call, not the pricing range.
Since the law of July 24, 2020, telemarketing is regulated. Professionals must adhere to time slots and consent rules. If the call is commercial and unsolicited, the problem is not the 0806 number, but the telemarketing practice itself.
Hanging up systematically on a +33 806 is treating the symptom rather than the cause. The prefix 0806 remains, in the current numbering plan, an indicator of standard pricing. Checking the range before blocking a number takes less time than later searching for another way to contact the relevant service.
