Running a “comment to win” or “tag a friend” giveaway inside a Facebook, LINE, or TikTok live sale puts the draw itself under Thailand’s Gambling Act, not just ordinary promotion etiquette. A permit is required before the sale, the winner has to be drawn by hand in front of witnesses, and the random-comment-picker tool most sellers reach for to do it is exactly what the rule forbids.
Your giveaway is a lucky draw under Thai law
Section 8 of the Gambling Act B.E. 2478 requires a permit to award free prizes through a draw connected to a business promotion — even when the organiser only benefits indirectly, such as more comments and reach on a live sale (Tilleke & Gibbins: Legal Requirements for Lucky Draws). The license comes from the Provincial Administration Department for a draw held in Bangkok, or the district (amphoe) office where the draw takes place anywhere else. Run one unlicensed and the penalty is up to a year in prison, a ฿2,000 fine, or both — a small fine on paper, next to a shop account that a platform or a reporting customer could flag over it.
The rule that breaks the “comment picker” bot
The part most sellers get wrong isn’t the permit — it’s how the winner gets picked. The same source states the selection has to happen physically and publicly in Thailand, with witnesses present, and that “selection by a computer or other automated means is strictly forbidden.” In practice that means printing out the eligible comments, putting them in a container, and drawing one by hand — even when every entry arrived as a Facebook or LINE comment. The random-picker apps and bots many live sellers already use to announce a winner in two seconds qualify as exactly the automated selection the rule rules out. After the draw, the organiser also has to report the winner’s details back to the licensing office.
What the permit costs, and why timing matters
Processing takes at least 15 working days, and the permit fee scales with how long the giveaway runs: ฿300 for one day, ฿600 for seven days, ฿1,500 for one month, ฿6,000 for six months, and ฿9,000 for a year (same Tilleke & Gibbins source). As a recommended default, not a legal deadline — apply at least three weeks before the live date you plan to announce, so the permit is in hand before the first “ร่วมกิจกรรมยังไงคะ” comment arrives. This sits next to a different registration duty — livestream selling itself falls under direct-marketing rules, with its own OCPB registration — so a seller running a giveaway inside a live sale can end up needing both.
Set up in 1CS
Draft the terms before the live starts, not while comments are flooding in. In Reply Templates (ตั้งค่า > คำตอบสำเร็จรูป on web, “คำตอบด่วน” on mobile), save a shortcode such as /giveaway with the entry period, prize type and value, draw date, and how the winner will be announced already filled in, so whoever is answering comments can paste it with / instead of typing it live. For comments using the words you expect — “ร่วมกิจกรรม”, “ขอลุ้น”, “วิธีร่วม” — an Automation rule (AI > เงื่อนไขอัตโนมัติ) with the event “ข้อความถูกสร้าง” (message created), a condition on “ข้อความ มีคำว่า” matching those words, and the action “ส่งข้อความ” can send the same terms automatically. Automation sits inside 1CS’s AI Agent tools; both screens are walked through, in Thai, at สร้างกฎอัตโนมัติ and ใช้คำตอบสำเร็จรูป — the same inbox habit that keeps a live’s buying-intent comments from scrolling past unanswered.
Terms to post before the giveaway starts
Post this with the giveaway announcement itself, not after the first person asks:
This giveaway runs from [start date] to [end date]. The prize is [prize description], worth approximately [value] THB. The winner will be drawn by hand from eligible entries on [draw date], witnessed as Thai law requires, and announced here within [X days]. We’ll message the winner directly to arrange delivery.
None of this changes how the live itself is run — it changes what has to be true before the “จับรางวัล” comment goes up: a permit on file, a printed list of entries, and a draw nobody can do with a bot.
