If you're sending money to Taiwan or setting up a local account, understanding the structure of Taiwanese bank account numbers is essential. While formats can vary slightly between institutions, most accounts follow a standardized 14-digit pattern that identifies the bank, branch, and individual account.
Taiwanese bank account numbers typically break down into three distinct components:
This three-digit code uniquely identifies the financial institution. Every bank operating in Taiwan—from major players like CTBC Bank and Mega International Commercial Bank to smaller regional institutions—has its own assigned code. For example, the Bank of Taiwan uses 004, while Cathay United Bank uses 013.
The next three digits represent the specific branch where the account was opened. Even within the same bank, different branches carry different codes. This helps route transactions to the correct location, especially important for banks with extensive branch networks across the island.
The final eight digits form the unique identifier for the individual account holder. Despite the name, this portion may include both numbers and letters depending on the bank's internal system.
Here's how a typical account number appears when formatted for readability:
123 456 7890 12
While this 3-3-8 format is widely used, some banks may employ variations. Post Office accounts, for instance, follow a different numbering system. Additionally, international transfers often require the bank's SWIFT/BIC code alongside the domestic account number.
For the most accurate and up-to-date information—especially when initiating transfers—always verify the exact format with the receiving bank directly or consult their official documentation. A small error in any segment could delay or misdirect your funds.
