Document Checklist
หนังสือเดินทาง (Nangsue Doen Thang — Passport)
Passport
Required: Original passport with at least six months of remaining validity. The bank scans the bio page and the latest entry stamp.
Used as: Primary identity document at the branch counter
Photocopies are not accepted in place of the original. The branch officer keeps a photocopy after inspecting the original passport.
วีซ่าไทย (Wiza Thai — Thai Visa)
Valid Thai visa
Required: Original passport page carrying the current visa stamp and the latest re-entry or extension stamp
Accepted: Non-Immigrant B (work), Non-Immigrant O (retirement, marriage, family), Non-Immigrant O-A (long-stay retirement), Non-Immigrant ED (education), LTR, or Thailand Privilege card with bundled visa
Tourist visas, visa exemptions, and the Destination Thailand Visa are not accepted by the four largest banks for a standard baht savings or current account.
หนังสือรับรองที่อยู่ (Nangsue Rap Rong Thi Yu — Residence Certificate)
Proof of Thai address
Strongest evidence: Certificate of Residence issued by the local Immigration office, based on the TM30 address-registration filed by the landlord when a foreign tenant moves in
Alternative: Lease agreement plus a utility bill (electricity or water) in the applicant's name; embassy letter of residence accepted variably
A government-issued Certificate of Residence is the most reliable evidence at any branch. Lease and utility bills in a third party's name routinely fail KYC. The TM30 filing by the landlord is the upstream document that enables the Certificate of Residence.
Thai mobile phone number
Required: Thai SIM registered in the applicant's own name with passport; used for SMS one-time-passwords and mobile-banking activation
Recency rule: Working at the time of branch visit
Third-party-registered SIMs — hotel, spouse, employer — are routinely rejected. Register the SIM at any mobile-operator shop with the passport before the bank visit.
Initial deposit
Required: Cash in baht at the counter, per the chosen product's published floor
Indicative range: ฿0 to ฿500 for a standard savings account at the four largest banks; ฿10,000 for a current account at the major two; check the institution's contract terms for the exact figure on the chosen product
Some products at Kasikornbank and the basic Krungthai banking account carry no hard minimum on the published page; Bangkok Bank, SCB, and the Krungthai standard savings account publish ฿500.
