Seasonal Changes
The 2025–26 Thai League 3 season features a number of changes compared to the previous campaign. These include the promotion and relegation of clubs between divisions, several club renamings and rebrandings, and the introduction of a new title sponsor, BYD Auto, which rebranded the competition as the BYD Dolphin League III for sponsorship reasons.
Promotions from Thailand Semi-pro League
Normally, the champions of each of the six regional groups of the 2025 Thailand Semi-pro League would be promoted to the Thai League 3.[2] However, in the Western region, the champions, The Wall, failed club licensing and were denied promotion. As a result, only five regional champions earned direct promotion, with several additional clubs promoted under special quotas due to licensing issues and adjustments to balance the number of teams in each group. Clubs promotion in the Northeastern region:
- Udon Banjan United – promoted as regional champions.[3]
- EUMT – promoted as runners-up under a special quota, as the group expanded from 11 to 12 teams. In addition, relegated side Khon Kaen Mordindang were reprieved due to Rasisalai United's promotion to Thai League 2.
Promotion to Thai League 2
Rasisalai United, the 2024–25 national champion, earned promotion to Thai League 2, representing a significant loss of a strong competitor for the region. As a result, no club was relegated from the Thai League 3 Northeastern region, as the bottom-placed side was allowed to remain for balance.
Sponsorship and Broadcasting
In the 2025–26 season, Thai League 3 will operate under a title sponsorship arrangement for the first time: BYD Auto (through BYD Rêver Thailand) has become the main sponsor for all three professional tiers in Thailand, including Thai League 3, rebranding it as the BYD Dolphin League III.[4]
On the broadcasting side, a landmark media rights deal was struck, giving AIS Play (in partnership with Gulf and JAS)[5] exclusive rights to stream all matches from Thai Leagues 1, 2, and 3, plus domestic cups and youth competitions for the 2025–26 through 2028–29 seasons.[6] Under this agreement, Thai League 3 matches can be watched live for free via AIS Play, and fans will no longer rely solely on individual clubs' streaming efforts (e.g., via YouTube or Facebook), as they did in previous seasons.
Club name and logo changes
2 clubs have rebranded or changed their logos for the 2025–26 season of the Thai League 3 Northeastern region:
- Korat City, formerly known as Suranaree Black Cat, underwent a rebranding before the 2025–26 Thai League 3 season. The change included both a new club name and a redesigned crest. The previous emblem, which featured a stylized black cat head in a minimalist design, was replaced with a modern shield-shaped logo that displays a grey cat head with a fierce expression under the banner Wonder Cat Korat City.
- Udon United, introduced a new crest ahead of the 2025–26 season. The previous logo featured a fox head design with white markings on the mouth and eyebrows on a bright yellow background. It was replaced with a simplified version that retains the fox head motif but with darker tones and a deeper yellow background, while maintaining the inscription "Since 2018" at the bottom of the shield.
