BrickLink

BrickLink operates as an online marketplace dedicated to the buying and selling of LEGO products, including individual parts, sets, minifigures, and accessories. The platform connects a global community of LEGO enthusiasts, collectors, and builders who use it to source rare or discontinued items and to sell their own inventories. Users can create personal storefronts, manage inventory lists, and engage in transactions through the site’s built‑in tools. BrickLink’s website serves as the primary interface for these activities, providing search functions, price guides, and trade‑related forums. The company’s headquarters are located in the United States of America.

BrickLink distinguishes itself by focusing exclusively on the LEGO secondary market, a specialization that sets it apart from broader e‑commerce platforms. Its niche positioning allows it to develop tailored features such as detailed part catalogs and condition grading guides that cater specifically to LEGO traders. The platform relies on external payment gateways to process transactions, which means it does not store payment card information on its own systems, a design choice highlighted during the 2023 security incident. In November 2023, BrickLink experienced a cybersecurity event that led to temporary downtime, prompted a precautionary lock of all user accounts, and required password resets upon restoration, although no payment data was compromised. Community forums reported ransom demands threatening store deletions during the incident, though official communications did not confirm this claim. After the restoration, BrickLink advised users on security practices and conducted thorough system assessments before returning the service to normal operation. Following the incident, BrickLink is owned by the LEGO Group, having been acquired by the toy manufacturer in 2019, making it a subsidiary within the LEGO corporate structure.
