E-commerce Definition: The Legal Definition in 2026

A craftsperson opening an online shop, an individual who regularly resells his or her creations on a marketplace, a services company offering its services through an app: all of them wonder at some point whether they fall legally within "electronic commerce" and what obligations follow. The question is not theoretical, because the classification triggers precise rules on customer information, the seller's liability, taxation and data protection. This guide explains the legal definition of e-commerce in 2026, the legal framework around it and the practical consequences of that classification for individuals and businesses alike.

E-commerce definition: what French law says precisely

In French law, electronic commerce is not a vague notion left to the discretion of the courts. It has a statutory definition, set out in Article 14 of Law No. 2004-575 of 21 June 2004 on confidence in the digital economy, known as the LCEN.

Electronic commerce is the economic activity by which a person offers or provides, at a distance and by electronic means, the supply of goods or services.

This definition of e-commerce rests on three cumulative elements that must be carefully distinguished.

The first is the existence of an economic activity. The law does not target mere online presence, but an activity directed at the supply of goods or services in an economic context. A personal blog with no transactions is not electronic commerce. By contrast, as soon as a sale, a paid booking or a remunerated service is arranged online, the criterion is met.

The second is the distance dimension. The seller and the customer are not physically present in the same place when the offer is made and accepted. This is what distinguishes electronic commerce from a sale in a shop, even if that shop has a showcase website.

The third is the electronic means. The offer and, where applicable, the conclusion of the contract take place through an electronic channel: website, mobile app, marketplace, automated professional messaging. The LCEN also specifies that services for which the recipient does not pay directly are included, such as certain services financed by advertising or by data collection.

This definition has its source in European law, and more precisely in Directive 2000/31/EC of 8 June 2000 on electronic commerce, transposed in France by the LCEN. The notion therefore sits within a framework harmonised across the European Union, which explains its stability over time despite the rapid evolution of digital practices.

Why the classification is decisive

Classifying an activity as electronic commerce is not an abstract exercise. This classification triggers a set of obligations of its own: reinforced legal notices, regulation of advertising, rules on the formation of online contracts, specific consumer protection. A person who sells regularly online without regarding himself or herself as an electronic trader is exposed to sanctions and disputes that he or she had not anticipated.

Take a simple case. An individual with a passion for photography sells his or her prints through a website he or she created, with online payment and shipping. Even without an incorporated company, once this activity becomes regular and profit-making, he or she is carrying on an electronic commerce activity and must register, display legal notices and comply with consumer law. The boundary between the occasional sale of personal goods and habitual commercial activity is decisive here.

The e-commerce legal framework in 2026: a layering of texts

The e-commerce legal framework is not limited to the LCEN. In 2026, it rests on a combination of national and European texts that complement one another. Understanding this architecture avoids the mistake of thinking that a single text is enough to achieve compliance.

The LCEN remains the foundation. It defines electronic commerce, sets the seller identification obligations in its Article 19, regulates online advertising and organises the liability regime of technical intermediaries (hosting providers and access providers).

The French Consumer Code applies as soon as the customer is a consumer, that is, an individual acting for purposes outside his or her professional activity. Articles L. 221-1 et seq. govern distance contracts and impose detailed pre-contractual information and a right of withdrawal.

The French Civil Code governs the formation of the electronic contract. Articles 1125 et seq. specify the conditions of validity of a contract concluded by electronic means, in particular the double-click mechanism that allows the customer to check the order before confirming it.

The General Data Protection Regulation, Regulation (EU) 2016/679, known as the GDPR, applies as soon as a site collects personal data, which is the case for almost every commercial site (delivery address, email, purchase history). The CNIL, the French data protection authority (Commission nationale de l'informatique et des libertés), monitors its application in France.

The Digital Services Act, Regulation (EU) 2022/2065, applicable since 17 February 2024, regulates online intermediary services, including marketplaces. The Digital Markets Act, Regulation (EU) 2022/1925, for its part targets very large platforms designated as gatekeepers.

Finally, Law No. 2024-449 of 21 May 2024 aimed at securing and regulating the digital space, known as the SREN law, adapted French law to these European regulations and reinforced certain obligations, in particular on combating illegal content and protecting minors.

This layering means that a single commercial site must comply simultaneously with several bodies of rules. An online shop selling to European consumers falls at once within the LCEN, the Consumer Code, the GDPR and, if it hosts third-party offers, the DSA.

Distinguishing e-commerce from neighbouring notions

Teaching the subject requires clear boundaries. Several notions are often confused with electronic commerce, although their legal regimes differ.

E-commerce and distance selling

Distance selling is a broader category than electronic commerce. It includes mail-order, telephone and paper-catalogue selling. Electronic commerce is one form of it, the form that operates by electronic means. Not every distance sale is therefore electronic commerce, but all B2C electronic commerce is a distance sale subject to Articles L. 221-1 et seq. of the Consumer Code.

E-commerce and information society services

The European notion of "information society service" covers any service provided at a distance, by electronic means and at the individual request of a recipient. It goes beyond commerce alone: a search engine, a social network or a listing service fall within it without necessarily selling goods. Electronic commerce is therefore a subset of information society services.

E-commerce and marketplaces

A marketplace connects third-party sellers and buyers without itself selling the goods. Its operator is not always the electronic trader: it may be an intermediary. This distinction is central, because it determines who bears the seller's obligations and who comes within the lighter liability regime for intermediaries provided for by the LCEN and clarified by the DSA. A seller who offers products on a marketplace remains, for its part, fully subject to the obligations of electronic commerce. The legal classification of marketplaces and the European regulation that governs them are analysed in our article on marketplaces.

The obligations that follow from the classification

Once the activity is classified as electronic commerce, a set of obligations applies. Ignoring them exposes the business to administrative sanctions, to the nullity of contractual clauses and to disputes with customers. These obligations are presented as a whole in our article on the essential legal obligations of e-commerce.

Identification of the seller

Article 19 of the LCEN requires the electronic trader to display legal notices allowing it to be clearly identified. For a company, this includes the company name, the registered office address, the telephone number, the email address, the registration number in the Trade and Companies Register (registre du commerce et des sociétés), the share capital and the intra-Community VAT number. For a professional trading in his or her own name, the surname and first name must appear. The absence or inaccuracy of these particulars is penalised.

Pre-contractual information for the consumer

Before the contract is concluded, Article L. 221-5 of the Consumer Code requires full information: the essential characteristics of the goods or service, the total price including all taxes, delivery costs, payment and delivery arrangements, the existence and conditions of the right of withdrawal, and the duration of the contract. This information must be legible and understandable, which rules out obscure references to general terms buried in the footer.

The right of withdrawal

Under Article L. 221-18 of the Consumer Code, the consumer has fourteen days in which to withdraw without having to give reasons or pay penalties. This period runs from receipt of the goods. Certain exceptions exist, for example for made-to-measure goods or digital content supplied immediately with the consumer's agreement. A seller who fails to inform the customer of this right has the period extended by twelve months.

Formation of the contract by double click

The Civil Code requires that the customer be able to check the details of the order and its total price, then correct any errors, before finally confirming. This is the so-called double-click mechanism: a first click summarises the order, a second validates it. The seller must then acknowledge receipt of the order without unjustified delay.

Protection of personal data

Every commercial site processes personal data and must comply with the GDPR: transparent information for individuals, collection of consent for non-essential cookies, data security, and keeping a record of processing activities. The CNIL monitors these obligations and regularly issues public sanctions, notably on cookie management and commercial canvassing. On the personal data protection obligations that weigh on the business under the GDPR, see our dedicated article on the subject.

In summary, these are the key obligations that an electronic trader selling to consumers must combine:

• display complete and accurate legal notices (Article 19 LCEN)
• provide clear pre-contractual information (Article L. 221-5 of the Consumer Code)
• guarantee a fourteen-day right of withdrawal (Article L. 221-18)
• organise the order using the double-click mechanism (Civil Code)
• comply with the GDPR for any data collection

Particular statuses: platforms, marketplaces and dropshipping

Electronic commerce covers very different models, whose legal regimes are clearly distinct.

The platform operator and the DSA

A marketplace operator that hosts the offers of third-party sellers in principle benefits from a lighter liability regime for the content it stores, provided that it acts promptly to remove manifestly illegal content as soon as it becomes aware of it. The DSA has reinforced its obligations of traceability of professional sellers, reporting of illegal content and transparency. A marketplace must now verify the identity of the professional sellers it hosts, following the principle known as "know your business customer".

Dropshipping

In dropshipping, the online seller markets products that it does not hold in stock and that are shipped directly by a third-party supplier, often located outside the European Union. Legally, this seller remains an electronic trader fully liable towards the consumer: it bears the information obligations, the statutory warranty of conformity and the right of withdrawal, regardless of the fact that the goods come from a third party. The DGCCRF, the French consumer protection and competition authority (Direction générale de la concurrence, de la consommation et de la répression des fraudes), monitors these practices closely, in particular misleading delivery times and product conformity.

The individual who crosses into commercial activity

The question keeps coming back: at what point does an individual selling online become an electronic trader? The criterion is the regularity and profit-making nature of the activity. Selling a few used personal items remains a private sale. Buying to resell, producing to sell, or making habitual sales with the intention of profit tips the activity into commercial activity, with an obligation to register and the application of all the rules of electronic commerce. Platforms moreover report their users' income to the tax authorities above certain thresholds, which makes this boundary increasingly visible.

Sanctions and risks in case of non-compliance

Failure to comply with the e-commerce legal framework exposes the business to several types of risk that should be assessed before launching.

In consumer matters, the DGCCRF may impose administrative fines and require a site to be brought into compliance. Failure to inform of the right of withdrawal or the use of pre-ticked boxes are regularly penalised.

In data matters, the CNIL has a power of sanction that may reach, under the GDPR, an amount proportionate to the company's turnover, and that is often accompanied by publication of the decision, which is particularly damaging to reputation.

In contractual matters, an unlawful clause may be deemed unwritten, and a breach of the information obligation may extend the withdrawal period or engage the seller's liability. To this are added the individual disputes that consumers may bring before the courts, as well as the class actions available in consumer law.

Conclusion: a simple definition, a demanding regime

The definition of e-commerce is, on its face, very simple: offering or providing, at a distance and by electronic means, the supply of goods or services. But behind this wording of Article 14 of the LCEN lies a dense regime that combines French law and several European regulations. The most frequent mistake, among individuals and businesses alike, is to believe that a commercial site amounts to a technical shop window, when it triggers a set of cumulative obligations. The risk does not come from a single forgotten text, but from the poorly mastered interplay between identification of the seller, consumer law, contract formation and data protection.

Before launching any online activity, have your site audited on these four dimensions: check your legal notices, your ordering process, your general terms of sale and your GDPR compliance. A preliminary check always costs less than a formal notice from the DGCCRF, a CNIL sanction or a dispute with a customer.

Frequently asked questions

What is the legal definition of e-commerce in France?

Electronic commerce is defined by Article 14 of Law No. 2004-575 of 21 June 2004 on confidence in the digital economy (LCEN) as the economic activity by which a person offers or provides, at a distance and by electronic means, the supply of goods or services. Three cumulative criteria are required: an economic activity, supply at a distance and the use of electronic means. This definition derives from European Directive 2000/31/EC of 8 June 2000.

Is an individual who sells online engaged in electronic commerce?

It all depends on the regularity and purpose of the sales. The occasional sale of used personal goods remains a private sale. By contrast, buying to resell or making habitual sales with an intention of profit is a commercial activity, which requires registration and compliance with all the obligations of electronic commerce. Platforms moreover report their users' income to the tax authorities above certain thresholds.

Which texts make up the e-commerce legal framework in 2026?

The framework rests on the 2004 LCEN, the Consumer Code (Articles L. 221-1 et seq. for distance contracts), the Civil Code (formation of the electronic contract, Articles 1125 et seq.), the GDPR, Regulation (EU) 2016/679, the Digital Services Act, Regulation (EU) 2022/2065 applicable since 17 February 2024, and Law No. 2024-449 of 21 May 2024 aimed at securing and regulating the digital space. These texts apply cumulatively.

Which legal notices are mandatory on a commercial site?

Article 19 of the LCEN requires the seller to be clearly identified. For a company, this includes the company name, the registered office address, a direct means of contact, the registration number in the Trade and Companies Register, the share capital and the intra-Community VAT number. For a professional trading in his or her own name, the surname and first name must appear. The absence or inaccuracy of these particulars is penalised.

Does the right of withdrawal apply to all online sales?

The fourteen-day right of withdrawal provided for by Article L. 221-18 of the Consumer Code applies to consumers, that is, to individuals acting outside their professional activity. It has exceptions, in particular for made-to-measure goods, perishable goods and digital content supplied immediately with the consumer's express agreement. Sales between professionals do not give rise to this statutory right.

Is dropshipping legal and what are the seller's obligations?

Dropshipping is lawful, but the online seller remains fully liable towards the consumer, even if the goods are shipped by a third-party supplier. It bears the pre-contractual information obligation, the statutory warranty of conformity and the right of withdrawal. The DGCCRF monitors misleading delivery times and the non-conformity of imported products in particular.

Is a marketplace liable for products sold by third parties?

The operator of a marketplace in principle benefits from the lighter liability regime for intermediaries provided for by the LCEN, provided that it promptly removes any manifestly illegal content of which it becomes aware. The Digital Services Act has reinforced its obligations to verify the identity of professional sellers and to ensure transparency. The third-party seller remains subject to all the obligations of electronic commerce.
