Frequently asked questions

Which card networks does Union Bank of Taiwan issue?

In our data Union Bank of Taiwan has 49 BINs: Mastercard (27 BINs), Visa (15 BINs), JCB (7 BINs). 4% are debit ranges and 96% credit ranges.

What are the first 6 digits of a Union Bank of Taiwan card?

The first 6 digits are the BIN. Union Bank of Taiwan BINs include 356056, 457953, 543381; the table above lists all of them. A BIN identifies the bank and card type, never a person or an account.

How do I contact Union Bank of Taiwan?

The BIN data lists the website www.ubot.com.tw and the phone number +886227180001. Card networks register these details with the BIN and banks change them over time: for anything about your own card, use the phone number printed on the back of the card or the bank’s official app.

Can I make a real, usable Union Bank of Taiwan card number from a BIN?

No. A number built from a BIN passes format checks (prefix, length and the Luhn check digit), but no bank issued it, so every real payment with it is declined. To test a checkout use your payment gateway’s sandbox test cards; to pay online without exposing your card, ask Union Bank of Taiwan or another issuer for a virtual card.

A BIN identifies the card network and the issuing institution only. It reveals nothing about an individual card, cardholder or account, and it cannot show whether a card exists or can be charged. Test numbers generated from a BIN are for development and QA only and are declined by every real payment system.
