• Round 2: 3 June – 31 July 2026 
• Round 3: 1 October – 30 November 2026

2026 will be the tenth year of SLD.th domain name registration organized by the THNIC Foundation which has now registered 269 SLD.th domains, particularly for businesses interested in registering domain names based on their trademark or organization’s name, followed by educational institutions, government agencies and non-government organizations respectively.

All SLD.th registration fees are contributed via the THNIC Foundation to support the Thai Internet Infrastructure Development and initiatives related to human resource development through capacity building activities.

To make registration as easy and efficient as possible, the THNIC Foundation has authorized T.H.NIC Co., Ltd., to serve as the official registrar responsible for .th domain name registration. However, as previously explained, the SLD.th registration fee will be donated directly to the THNIC Foundation.
