Are There Entry Limitations for ASEAN Nationals Crossing into Thailand by Land?

FYI...update report from Amornrat:

From the ASEAN group only Filipino are still limited to 2entry per land without visa.

Others are unlimited (Singapore/Brunei/Indonesia added last year).

Myanmar need visa to enter by land, “unlimited” by air 14days).

What is your nationality?

It depends on the country.

Brunei, Indonesia, Malaysia, and Singapore qualify for the 30 day visa exemption but explicitly don't have the 2 per year restriction.

The Philippines gets the 30 day visa exemption but does have the 2 per year restriction.

Laos and Vietnam get a 30 day visa waiver under bilateral agreement rather than a visa exemption, the policy towards these may depend on the border, I do not know. I think Laotians at least can come in from Laos. Cambodia gets 14 days under bilateral agreement. Myanmar I think get zero exempts by land, I think they need to fly in if they don't have a visa. I think there is no formal limit on any of these, but that doesn't necessarily mean unlimited at any border, but that it is up to the discretion of the IO.

I'm not 100% on every country, particularly the details for the bilateral treaty ones but if YOU are from the Philippines, I am pretty sure you are limited to 2 land entries per year. The Philippines was on the original document about that, and while Malaysians were exempted from the 2 per year limit from the start, and Indonesia/Malaysia/Brunei were more recently, the Philippines was not. And I also know at least one Filippino they did do the (1) (2) marking on his land border bounces same as they do for a Westerner.
