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 Southern region:
- Samui United – promoted as regional champions.[3]
- Chumphon United – promoted as runners-up under a special quota, after Songkhla and Pattani were promoted to Thai League 2, and Phatthalung failed licensing, leaving three vacancies in the group.
Promotion to Thai League 2
Songkhla and Pattani achieved promotion to Thai League 2, having finished as the national runners-up and third place, respectively. Both clubs will be missed in this region, where they were top performers.
Club relegated due to club licensing failures
In addition to the regular relegations, one club was demoted from the Thai League 3 Southern region after failing to obtain a club licensing certificate for the 2025–26 season.
- Phatthalung – failed licensing and were relegated.
Club relegated due to finishing last in the region
Alongside the licensing-related relegations, one club was demoted from the Thai League 3 Southern region after finishing at the bottom of the respective regional leagues in the 2024–25 season.
- Yala City – relegated after finishing bottom in the Southern standings.
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 changed their logo for the 2025–26 season of the Thai League 3 Southern region:
- Chumphon United, a newly promoted club from the Thailand Semi-pro League, has updated its logo by adopting a more dimensional appearance.
- PT Satun changed their logo by adding text "PT" into the club's logo and renamed to "PT Satun".

Road travel distances between clubs
The distances between football clubs in the 2025–26 Thai League 3 Southern Region are approximate and calculated based on the shortest practical and most accessible road routes. Given the geography of southern Thailand, these measurements also take into account necessary ferry travel, notably for Samui United, which is located on Ko Samui in Surat Thani province and requires sea transport to reach the mainland. By prioritising realistic travel conditions, the chart reflects the actual journeys clubs must undertake for away fixtures and highlights the logistical complexities unique to the region.
Among the measured distances, the shortest is 72 kilometres, separating Nara United and Yala. In contrast, the longest road journey spans 704 kilometres, representing the trip between Nara United and Ranong United. Regarding cumulative travel across the season, Nara United faces the heaviest burden with a total travel distance of approximately 4,165 kilometres. Meanwhile, PSU Surat Thani City records the lowest total at around 2,295 kilometres. These figures are detailed in the accompanying table, offering a comprehensive overview of inter-club road distances and illustrating the significant logistical challenges encountered by teams during the 2025–26 campaign.
