The Law is built on the distinction between service providers (ETHS) and intermediary service providers (ETAHS). The 2022 reform introduced prohibitions on unfair commercial practices, data portability, limits on trademark use, obligations graduated by net transaction volume and the e-commerce license regime. For commercial electronic messages, consent obtained through the İYS (Message Management System) is mandatory.
Overview
Law No. 6563 (Türkiye’s Electronic Commerce Law) establishes the framework for electronic commerce in Türkiye. The comprehensive amendments made in 2022 by Law No. 7416 reordered the balance of power in the marketplace ecosystem, the conditions of competition and the seller–platform relationship. By a Constitutional Court ruling published in the Official Gazette on 2 June 2026 (E.2024/187, K.2026/42), Article 9(1) — under which marketplaces (ETAHS) were not liable for unlawful content and products — was annulled in respect of consumer transactions; the annulment takes effect on 2 March 2027.
The ETHS / ETAHS distinction
The backbone of the law is the distinction between the electronic commerce service provider (ETHS), which sells on its own account, and the electronic commerce intermediary service provider (ETAHS), which intermediates the sales of others. Obligations are tiered according to net transaction volume and number of transactions; at the top tier, an e-commerce license comes into play.
Rules that protect sellers
The reform introduced limits on platforms offering their own brands for sale, portability of seller data, protections against unilateral contract changes, and prohibitions on unfair commercial practices. For companies selling on a marketplace, the intermediation contract’s conformity with this mandatory framework is a right that can be scrutinised.
Key point for cross-border sellers
The separation of overseas sales in threshold calculations makes export-oriented e-commerce models advantageous. For sales from Türkiye to the EU, the Law No. 6563 regime must be addressed in a single compliance plan together with the DSA, GDPR and VAT rules.
Roadmap
Status and threshold analysis; verification of ETBİS and İYS records; review of platform contracts; audit of campaign and advertising practices; and tracking the provisions that changed following the Constitutional Court (AYM) ruling.
Penalties
Supervision rests with the Ministry of Trade; graduated administrative fines are applied according to the type of breach, and for unfair commercial practices and certain platform obligations the fines can reach substantial amounts. Message-consent violations (the İYS regime) are penalised separately.
