The .SRL domain extension is a generic top-level domain (gTLD) intended for use by companies registered as Società a responsabilità limitata (Srl) in Italy and other countries where this type of company exists. Srl is the Italian version of a limited liability company, meaning that its owners are not personally liable for the company's debts. Srl owners are referred to as partners and typically hold a share in the company. Srl companies are often used by small and medium-sized enterprises.

The .SRL domain zone offers Srl companies the opportunity to create unique domain names for their websites, showcasing their corporate identity and recognition on the Internet.

Registering a domain name in the .SRL domain zone is available to all interested Srl companies, regardless of the company's location. However, during the registration process, it is necessary to provide documents confirming that the company is indeed an Srl.

The .SRL domain extension was launched in 2015 and is managed by Registro .SRL, the official registrar of .SRL domain names.
