- Pak Bang subdistrict municipality (เทศบาลตำบลปากบาง), Sing Buri province renamed to Phrom Buri (เทศบาลตำบลพรหมบุรี) [Gazette].Being the central municipality of Phrom Buri district and covering the complete subdistrict Phrom Buri, I actually wonder why the sanitary district created in 1964 and upgraded to municipality 1999 till now had a different name.
- Bang Kaphi TAO, Lopburi (องค์การบริหารส่วนตำบลบางกะพี้) renamed to Bang Kaphi Dong Phlap (องค์การบริหารส่วนตำบลบางกะพี้ดงพลับ) [Gazette]. In 2004, the TAO Bang Kaphi and the TAO Dong Phlap were merged, however the enlarged TAO kept the name of its major part. Now both subdistricts covered are represented in the name.
- Ko Loi TAO, Chonburi (องค์การบริหารส่วนตำบลเกาะลอย) renamed to Ko Loi Bang Hak (องค์การบริหารส่วนตำบลเกาะลอยบางหัก) [Gazette]. In 2004, the TAO Ko Loi and the subdistrict council Bang Hak were merged, however the enlarged TAO kept the name of its major part. Now both subdistricts covered are represented in the name.
Even though the changes are not in effect yet, I have already updated the corresponding Wikipedia articles, and also created the Wikidata items for these three local governments with all their data.
