Frequently asked questions
Which card networks does Citibank (Hong Kong) issue?
In our data Citibank (Hong Kong), Ltd. has 138 BINs: Maestro (100 BINs), Mastercard (21 BINs), Visa (16 BINs), Cirrus (1 BIN). 80% are debit ranges and 20% credit ranges.
What are the first 6 digits of a Citibank (Hong Kong) card?
The first 6 digits are the BIN. Citibank (Hong Kong), Ltd. BINs include 400975, 666008, 666054; 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 Citibank (Hong Kong)?
The BIN data lists the website www.citibank.com.hk and the phone number +85228600333. 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 Citibank (Hong Kong) 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 Citibank (Hong Kong) 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.
