A card that starts with 521118 runs on the Mastercard network, is a debit card, was issued by United Overseas Bank, LTD. and comes from Singapore. Payment systems read these first six digits before anything else: to route the transaction to the right network, to apply interchange and currency rules, and to flag mismatches between the card's country and the buyer's location.
A BIN identifies a range of cards, never one account. Knowing it tells you nothing about any individual cardholder. To test how your checkout handles Mastercard cards, use Mastercard test numbers for form validation, and your gateway's official sandbox cards for payment flows.
