The page stays published because the question comes up, and a clear answer beats an absence. It is not proposed for indexing: we do not send anyone to a page that cannot deliver the service they came for.
The rail in numbers
All these values come from the catalogue published on this site, and are republished as soon as our own measurements contradict them.
- Technical nature
- Instant bank transferSettlement in individual messages: the receiving bank must answer within seconds. That is what makes the rail usable at night and on weekends.
- Settlement currency
- THB — Thai BahtIf this is not your account currency, your bank applies its own conversion on arrival. That cost does not go through us and does not appear in our breakdown.
- Settlement delay (p50 / p95)
- 2 min / 30 minThe median describes the common case, the p95 the slow one. We show both: a median alone hides exactly what worries you.

How this rail actually works
The identifier points to the account declared with the bank, which avoids exchanging an account number. Settlement is immediate between institutions.
Opening depends on a partnership with a locally licensed payment institution. Until one exists, Thailand stays served by international wire.
What makes the delay
This rail processes orders continuously: there is no business day and no cut-off. The gap between the median and the p95 of 30 min comes from the availability of the receiving institution or operator, not from a clearing window.
Details required from the beneficiary
Every field is validated as you type, with the same rule client-side and server-side. That is what prevents most rejected payouts.
| Field | Type | Required | Validation rule | Why |
|---|---|---|---|---|
| PromptPay ID | Text | Yes | format checked before sending · digits only kept | 10-digit mobile number or 13-digit national ID. |
| Account holder name | Text | Yes | 2 to 140 characters · edges trimmed | Must match the name verified on your ID exactly. A mismatch gets the transfer rejected. |
The rules shown are the ones actually enforced: there is no “marketing” version of this table differing from the code.

Why we keep this page online
A closed rail nobody mentions looks like an oversight. A documented closed rail, with its exact reason and what is missing to open it, gives you the answer in one read — and saves you from creating an order that would go nowhere.
Frequently asked questions about PromptPay
How fast does PromptPay credit my account?
under 5 minutes in half the cases, and up to 30 min in the slowest ones. This rail runs continuously, weekends and holidays included. These are market orders of magnitude, not a contractual commitment.
What are the minimum and maximum amounts on PromptPay?
Between THB 100.00 and THB 200,000 per operation, in Thai Baht. These bounds belong to the rail itself. An amount above the cap is split into several payouts, which multiplies any fixed fee accordingly.
What does a PromptPay payout cost?
0.50% for the rail itself. That amount appears as its own line in the breakdown, next to the network cost taken from your deposit and our spread. The lines sum to exactly the gap between the mid-market value and what you receive.
What do I need to provide to receive on PromptPay?
2 fields: PromptPay ID, Account holder name. Every format is validated before the order is accepted, not at send time: a typo is flagged immediately, not three days later as a rejection.
Which assets can I sell to PromptPay?
0 assets are offered on this rail. The asset does not change how the rail works: it changes the confirmation time before the payout leaves, and the spread applied depending on whether the asset is stable or volatile.
Any pitfall to know about PromptPay?
Opening depends on a partnership with a locally licensed payment institution. Until one exists, Thailand stays served by international wire.
