In France, cycling has long been an established mode of daily transportation. In Paris and throughout the Île-de-France region, it's used for commuting to work, university, getting around the city, or simply enjoying a ride. But with the rise in cycling, another phenomenon has gained momentum: bicycle theft. It was to address this problem that mandatory bicycle marking was introduced: it allows a bicycle to be identified, linked to its owner, and increases the chances of recovering it if stolen. With the experts from Routes and Roads, let's review bicycle marking and its benefits for cyclists.

Conclusion
Bicycle marking has been mandatory in France for all new bicycles sold by professionals since January 1, 2021. For used bicycles sold by professionals, this obligation came into force on July 1, 2021. Bicycles purchased before these deadlines or sold between private individuals are not systematically concerned, but identification remains highly recommended as an additional protection against theft.
How mandatory marking appeared in France
The main objective is to combat theft and the resale of stolen bicycles.
Without an identification number, it is difficult to return a recovered bicycle to its owner: the police or competent services cannot always prove who it belongs to.
Marking provides a simple solution to this problem. A unique identifier is affixed to the frame, then the bicycle's and its owner's information is registered in the national FNUCI database — Fichier National Unique des Cycles Identifiés (National Unique Database of Identified Bicycles). This database is administered by APIC on behalf of the State.
Concretely, this creates an official link between the bicycle and its owner. Marking does not completely protect against theft, but it significantly complicates its illegal resale and makes it easier to prove ownership of the bicycle.

What is bicycle marking
Marking consists of assigning a unique identification number to the bicycle, affixed directly to the frame. It can take different forms: engraving, secure label, capsule, or other approved solution. This number must remain visible and accessible for verification without disassembling the bicycle.
Once marked, the bicycle is registered in the FNUCI database. Associated with this number are the owner's details: name, contact information, and bicycle-related information. This allows the owner to be quickly contacted if the bicycle is found after theft or loss.
Systems like Bicycode and Paravol are among the identification operators. As Paravol has merged with Bicycode, it is normal to still encounter both names in your searches.
Which bicycles are subject to mandatory marking
Mandatory marking concerns bicycles sold by professionals in France. This includes both classic bicycles and electric bicycles, whether sold new or used by a store, workshop, or any other retailer.
If you buy a new bicycle from a bicycle store in Paris, it must be identified. The same applies to a used bicycle bought from a professional.
If the bicycle is sold directly between private individuals, the regulations work differently: prior marking is not always mandatory, but checking the bicycle's status remains essential before any purchase. This is a simple precaution to avoid buying a stolen bicycle and to ensure that the seller has the necessary proof of purchase.

All bicycles are subject to mandatory marking
How the marking procedure works
The marking procedure is generally quick. The bicycle is first inspected, then an identification number is affixed to the frame. Information relating to the bicycle and its owner is then registered in the national database. Once the operation is complete, the owner receives confirmation that their bicycle has been identified.
To carry out this procedure, you may be asked to present the bicycle, a form of identification, and proof of purchase if available. Depending on the operators, sometimes only the owner's contact details and the bicycle's characteristics may be sufficient. It is best to check the conditions directly with the workshop or identification operator.
The price depends on the method used and the service provider. APIC generally indicates a cost between €10 and €30, depending on the chosen identification solution.
How to check a bicycle's marking
This verification is particularly important when buying a used bicycle. The first step is to locate the number on the frame. It is usually in a visible location and may appear as an engraving, a secure sticker, or a capsule.
It is then possible to check the bicycle's status via APIC's verification service. This verification allows you to know if the bicycle has been reported stolen and to ensure that it can be purchased safely.
If the number is absent, damaged, or if the seller cannot explain the bicycle's origin, it is best to be cautious and ask for clarification. This vigilance is particularly important when buying a high-end city bike, a gravel bike, or an electric bike in Paris and the Île-de-France region.
What to do when buying or selling a bicycle
When buying a new bicycle from a professional, the procedure is usually simple: the marking has already been done, and your information is registered at the time of sale.
For a used bicycle, three points need to be checked: the presence of the identification number, consistency with the documents provided, and the absence of any theft report. If the bicycle is already registered, the information must be updated when the ownership changes.
When selling a bicycle, it is important to provide the buyer with all information related to the marking and to correctly transfer ownership. This protects both parties: the buyer has proof of legal origin, while the seller is no longer officially linked to the bicycle after the transaction.

It is possible to check the status of a bicycle via Bicycode and the national APIC registry.
How marking helps in case of theft
In the event of theft, marking allows law enforcement, competent services, and potential buyers to identify the bicycle. A recovered bicycle can be identified by its number and linked to its owner via the database.
It is important to understand that marking does not replace a good bicycle lock or good parking habits. It does not prevent theft on its own, but it makes resale more complicated and increases the chances of recovery.
Its effectiveness is maximized when accompanied by simple security measures: a robust lock, parking in visible areas, photos of the bicycle, and keeping proof of purchase.
Don't forget that a reliable lock significantly reduces the risk of bicycle theft. On the Routes and Roads blog, you will also find articles explaining how to choose a lock as well as a selection of the most reliable models.
Frequently asked questions from cyclists
Can you ride without marking?
If the bicycle was purchased before the regulation came into force or from a private individual, the situation may be different. However, a bicycle sold by a professional in France must have its identification number.
Should an old bicycle be marked?
Even if it is not always mandatory, it is highly recommended. It is particularly useful if you regularly cycle in Paris, leave your bicycle parked outside, or plan to resell it.
What to do if the marking is damaged?
It is best to contact an identification operator or a bicycle workshop. A damaged number can complicate verification.
How to check a used bicycle before purchase?
Locate the number on the frame and check its status in the database. In its absence, ask the seller for documents and carefully assess the situation.
Are Bicycode and Paravol the same thing?
These are two related systems. As Paravol has been integrated into Bicycode, it is normal to find both names on older documents or some websites.

Marking helps locate a stolen bicycle and return it to its owner.
Where to get your bicycle marked in Paris
If you buy your bicycle in a store, the marking is generally done directly at the time of sale. If you already own a bicycle and wish to have it identified, you can contact an approved operator or a bicycle shop in Paris that works with these services.
At Routes and Roads, all bicycles sold are identified in accordance with current regulations. Our team also assists you in checking a bicycle before purchase and advising you on theft protection solutions.
Conclusion
Bicycle marking in France officially links a bicycle to its owner, makes the resale of stolen bicycles more difficult, and increases the chances of recovery after theft.
If you buy a new or used bicycle, remember to check its identification before purchase. And if you already cycle in Paris or Île-de-France with an unmarked bicycle, registration remains a particularly useful additional protection.
At Routes and Roads, we support you with marking, verification, and maintenance of your bicycle so that it remains reliable for everyday use and better protected against theft.
