Heads up: I'm at the Ban Pakard (Cambodia) land border crossing (Cambodian side) and an official here is telling me this border crossing has been closed on the Thai side by the provincial government for fourteen days. Another official here just called his counterparts at Poi Pet and said the border is still open there.
Update: My driver from Ban Pakard took me to the Ban Laem crossing because it was closer and it was open, so I don't know for sure if Poi Pet is open.
TLDR : Answer Summary
The Ban Pakard border crossing is currently closed on the Thai side for fourteen days, according to an official at the Cambodian side. However, there are conflicting reports about the status of the Poi Pet border, which may still be open. Travelers are advised to check the latest updates or consider using alternative crossings like Ban Laem.
