Everything You Need to Know About Hong Kong Bank Account Formats in 2025 

Hong Kong is one of Asia’s foremost financial hubs, attracting individuals and global businesses for its efficient banking system and strategic location. Navigating the banking landscape here starts with understanding the Hong Kong business bank account opening process, from account formats and eligibility to documentation and onboarding. This comprehensive guide equips you with what you need to succeed. 

Understanding Hong Kong Bank Account Formats 

Each Hong Kong bank account includes three main components: the 3-digit bank code, 3-digit branch code, and the unique account number consisting of 6 to 9 digits. For example, the format might appear as XXX-YYYYYYYYY where XXX is the branch code, and the latter is the account number. This structure enables smooth local and international fund transfers, as Hong Kong follows its own system rather than IBANs for cross-border transactions. Knowing precise account formats and bank codes (e.g., 004 for HSBC, 024 for Hang Seng) is essential for correctly routing payments and avoiding delays. 

Eligibility Criteria and Requirements for Account Opening 

  • Individuals: Hong Kong residents and non-residents over 18 can open personal bank accounts. Required documents include valid HKID or passport, proof of address, income verification, and a Hong Kong contact number. 
  • Businesses: Companies registered in Hong Kong, including foreign-owned, can open business accounts. They must provide incorporation certificates, business registration, proof of business operations, and detailed information on directors and shareholders. 

Essential Documents for Corporate Bank Accounts 

Hong Kong banks implement strict Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations, requiring a comprehensive set of documents, including but not limited to: 

  • Certificate of Incorporation and Business Registration Certificate 
  • Memorandum & Articles of Association 
  • Board Resolution authorizing account opening 
  • Organizational chart displaying shareholders and ultimate beneficial owners (UBOs) 
  • Identification (passports/HKID) and residential proof for directors, shareholders, and authorized signatories 
  • Business plan and evidence of business activities such as contracts or invoices 
  • Additional documents such as share certificates, directors’ CVs, and bank reference letters may be required for enhanced due diligence.

How Foreign Companies Can Streamline Hong Kong Bank Account Opening

  • Clear business description: Being ready to clearly explain business models and cash flow sources to bank officers. 
  • Choosing banks with efficient onboarding: Opting for banks or virtual banks known for quicker, more digital onboarding suited to international clients. 
  • Engaging local corporate service providers: Using expert consultants familiar with bank preferences and documentation nuances to guide the process. 
  • Leveraging digital banking channels: Utilizing virtual banks with streamlined Know Your Customer (KYC) processes. 
  • Preparing for compliance interviews: Facilitating in-person or video interviews for directors and shareholders with transparency and honesty.
