What the last check found

TMB Bank is TMBThanachart Bank Public Company Limited, brand "ttb", a Thai commercial bank with its head office in Bangkok. Its own English site carries the TMBThanachart legal name, and 2C2P's payout directory still lists it as "TMB Bank Public Company Limited (TTB)" at Thai bank code 011. The "TMB Bank" label is the pre-merger brand, so expect stale naming: gateways that carry it usually also carry a separate "Thanachart Bank" entry for what is now the same institution.

It is not a standalone rail. It is one bank inside an aggregator's Thai bank menu, and the only gateway documentation that names it is 2C2P's Payment Channel Matrix, where agent code THTMB appears under four channel groups, all on channelCode 123 and all country TH: Internet Banking (IBANKING), Web Payment (WEBPAY), Pay at Counter (BANKCOUNTER) and ATM / self-service machines. 2C2P's SDK pages for those exact channels use currencyCode THB; the matrix itself has no currency column, so THB rests on the channel examples plus the bank's domestic-only footprint, not on a per-bank statement.

No one else names it. Adyen, Airwallex, Stripe, Checkout.com and dLocal publish only an unbranded "Online banking Thailand" wrapper or no bank list. Antom names six Thai online-banking banks (BBL, BAY, GSB, KBank, KTB, SCB) and omits TMB. Payouts are better documented than pay-ins: 2C2P code 011, Opn/Omise recipient code ttb. Documentation is silent on refunds, recurring and chargebacks for this channel (2C2P only says "certain 123 payments" refund asynchronously), and 2C2P's cut-off-time table omits THTMB. Web search was unavailable this run; all findings came from direct doc fetches.

Checked against TMB Bank’s own documentation on 21 October 2026. Coverage changes; confirm anything you are about to build on.
