Voice phishing simulations in Thailand
Thailand reads differently from its neighbours in both directions, and a voice phishing simulation here is gated by a document rather than by a regulator. The privacy statute is a prohibition with exceptions rather than a menu of grounds, the criminal code contains no eavesdropping offence at all, and any disciplinary consequence the programme can lead to has to already exist in your posted work rules before the first call rather than be constructed after the first result.
Phone numbers
Supplied by Callstrike
Local numbers in Thailand, after a one-time approval.
Running a simulation
Permitted, and the work rules gate it
Discipline has to be in the posted rules before the campaign, not written afterwards.
Consent
Strained by the statute itself
The freely-given test is what pushes an employer to the balancing exception instead.
Getting a phone number in Thailand
One approval per country, completed in the console.
Provisioned by Callstrike after approval
Numbers here are not released from open inventory. Your workspace is cleared for this country once, and Callstrike then provisions a dedicated number against it for your simulations. Approval is a one-time, per-country step and usually takes 3 to 5 business days. We only ask for what the regulator requires.
The Thai table below has one line that catches companies out and it is not the address. Both the name and the identity number of your legal representative have to be evidenced by a Thai government-issued identity card, so a company whose authorised signatory is not Thai has a problem to solve before the filing rather than during it. Alongside that, the business name and the business registration number come from an excerpt of the commercial register, and the console form asks you to type your business type.
The address line is the ordinary regional one: it has to fall inside the locality covered by the number's own prefix, evidenced by a register excerpt, a utility bill, a tax notice, a rent receipt or a title deed, and a post office box is not accepted where a local address is required. Plan the number's area code and the address you can evidence together rather than in sequence.

Is it lawful to run a simulation in Thailand?
The position in short, before your counsel reads the detail below.
Yes, and the first thing to get right is structural, because getting it wrong changes every sentence after it. The Personal Data Protection Act does not set out co-equal grounds. It opens by providing that the controller shall not collect personal data without the agreement of the data subject unless one of six situations applies, so Thailand is agreement-default with carve-outs and anyone describing it from the European regulation will describe it incorrectly. The situation an employer works from is the fifth: necessity for the legitimate interests of the controller or another person, except where those interests are overridden by the fundamental rights of the data subject. Read that clause carefully, because the words for freedoms do not appear in it and a Thai assessment should quote the Thai wording rather than the European formula it resembles.
A second structural point follows from the same drafting and changes how the assessment is written. That provision governs collection, and the Act treats use and disclosure separately, so the Thai analysis is not the single one-shot selection the European model encourages. Work through collection, use and disclosure as three questions and record three answers.
On agreement, Thailand belongs with Czechia and Israel in this portal, and the reason is in the statute rather than in a regulator's opinion. A request has to be made explicitly in writing or by electronic means, presented in a manner clearly distinguishable from other matters, in an easily accessible and intelligible form, in clear and plain language, and not deceptive or misleading as to the purpose. The controller then has to take utmost account of whether the agreement is freely given, and the data subject may withdraw it at any time. An employment relationship strains every one of those, which is why the balancing carve-out rather than agreement is the realistic route, and it is also why what your staff were told still has to be evidenced even though it is not what the processing rests on.
Recording is the one thing this page cannot resolve, and the reason is unusual enough to be useful. There is no Thai eavesdropping offence: the words for eavesdropping, intercepting, listening in, conversation and recording device return zero across all three hundred and ninety-eight sections of the penal code, and the provisions that do exist cover sealed physical correspondence, a closed list of professions that excludes an employer and a testing vendor, industrial secrets, and state telecoms officials. The one remaining candidate is a computer crime provision with five cumulative elements that on its face does not catch a party to the call, but whether a telephone call is computer data within a computer system for its purposes is unresolved on every source reachable under this portal's standard. Thailand is neither the all-party model of the Philippines nor the participant-permitted default of Europe, and we are not going to borrow either.
What your company needs to do
8 items, in the order you will need them.
- Decide whether failing can carry a consequence, before you buyThailand-specificDiscipline and disciplinary penalties are one of the eight matters the work rules must contain, and the basis for any consequence has to exist in the posted rules before the campaign runs. Constructing it afterwards is the failure mode, and it is the one Thai decision that has to be made before a purchase rather than during a rollout.
- Post the work rules in Thai where staff can read them convenientlyThailand-specificAt ten employees in total the rules have to be announced within fifteen days, a copy kept at the establishment at all times, and the rules publicised and posted openly at the workplace so employees may know and read them. Where they are amended, the amended rules have to be announced within seven days of being brought into use.
- Do not file the work rules with the labour departmentThailand-specificThe duty was removed and the provision says so in terms: there is no need to send a copy to the Director-General or a delegate. Several Thai government pages state the removal expressly, which suggests the stale belief is common enough to be worth correcting on a checklist someone else wrote.
- Make sure the grievance route is in the same documentThailand-specificGrievances are a separate one of the eight required matters, and it is where an employee who objects to having been tested will go. Knowing that in advance is the difference between a complaint that has a route and one that arrives somewhere nobody expected it.
- Record the balancing exception three times overThailand-specificOnce for collection, once for use and once for disclosure, because the Act treats them separately. Quote the Thai override wording rather than the European one: the clause reads overridden by the fundamental rights of the data subject, with no freedoms limb, and whether that narrows the override in practice is untested.
- Write the security measures down and review them when the technology changesThe statute imposes a standing duty to provide appropriate measures preventing unauthorised or unlawful loss of, access to, use, alteration, correction or disclosure of personal data, reviewed when necessary or when the technology changes, and in accordance with the minimum standard the committee announces.
- Present a Thai number exactly as it was allocatedThailand-specificThe rule is not in the anti-scam emergency decree everyone reaches for, which carries no caller identity provision at all. It is a clause in the numbering notification requiring a number to be used exactly as allocated without any modification whatsoever, naming the display of the originating number as a case it covers. It admits no modification, so this is not a question of whether the number you present is misleading.
- Take an employee committee to Thai counsel if you have oneThailand-specificThe work rules provisions contain no consultation, agreement or negotiation step at all, and the verbs are to provide and to announce. What this page has not covered is the labour relations statute's employee committee, which is a separate institution with its own threshold and its own duties, so a work-rules provision that contains no consultation step is not Thailand having no consultation duty anywhere.
The controls that do the work
How Callstrike is configured, and which provision in Thailand each choice answers.
Auto-hangup before disclosure
The bot ends the call at the moment an employee starts to give up a credential or a piece of personal data, so the thing the pretext asked for is never spoken into the system and never stored.
Thailand has no acquisition-by-deception offence for this to dispose of, so what it answers here is the shape of the assessment rather than a criminal provision. The override clause is bare, reading overridden by the fundamental rights of the data subject with no freedoms limb and no case law on it, and the Act makes you justify collection, use and disclosure separately. A credential that is never spoken into the system is not three questions you have to answer, it is none, and the smaller the exercise's actual collection the less weight that untested override is ever asked to carry. It also keeps the security duty proportionate to something you are still holding a year later.
In-call debrief and follow-up
A second voice breaks character as soon as the call ends, explains what just happened and why it worked, and a follow-up email repeats it in writing while the moment is still sharp.
Two of the eight matters your work rules have to contain are discipline and grievances, and both of them are about what happens to a person after they fail. A second voice that breaks character the moment the call ends, with vishing training in writing the same day, keeps the exercise out of the disciplinary limb entirely, which is the cleanest way to answer the decision this page opens with, and it is also the reason most people never reach for the grievance route in the first place.
Consent Management
Two modes: collect consent now, over email, Slack or Teams with a full audit trail per employee; or record that your organisation already has this covered, by uploading the policy, handbook clause or agreement and confirming the scope it applies to. The document is hashed, the attestation is signed and timestamped, and an audit email is issued. Included on every plan.
Agreement is not what the programme rests on, because the statute's freely-given test is one an employment relationship strains, and the balancing carve-out is the realistic route instead. What is distinctly Thai is that the work rules mechanism is unilateral promulgation plus publication, with nothing filed anywhere: you announce, you keep a copy at the establishment and you post them openly. Nobody can later prove from a notice board that the rules reached a particular person, and a dated per-employee record that they did is exactly the evidence that publication duty cannot leave behind on its own.
SCORM module
An interactive web presentation on voice-phishing risk, delivered through your own LMS, which then invites the learner to opt into a web call with the bot. A call the person starts themselves in a browser is not a telephone call, so telephony rules do not reach it.
The Thai numbering clause is the friction worth designing around, because it admits no modification whatsoever and it binds the allocatee, which means it reaches you through whichever Thai party holds your numbering. A learner-initiated session presents no number for that clause to be about: Callstrike's vishing simulator carries the same deepfake voice into a web call the learner opens after working through the module. State the limit honestly, though. There is no Thai synthetic-voice disclosure duty for the module to satisfy, and the computer crime provision on manipulated content says image throughout with no voice limb, so this route answers delivery rather than an obligation that does not exist.
Consent Management is included on every plan. See AI voice phishing simulation and human-in-the-loop voice phishing for how each is delivered.
