FakecreditcardAbout BIN 520961
In our BIN data, 520961 is a Mastercard Platinum debit card range that belongs to South American International Bank Curacao, registered in Curaçao. Debit cards draw money directly from the cardholder's bank account, so checkouts and gateways often treat them differently from credit cards (fees, holds, recurring billing). Platinum is a premium tier; the issuer sets the benefits and limits, but it ranks above the entry-level products.
South American International Bank Curacao has fewer than ten BINs in our data, so it has no bank page.
Across Curaçao, the dataset counts 119 BINs; among the 113 that name an issuer, the main networks are Mastercard (51%), Visa (49%), and 29% are debit. See the Curaçao BIN list.

Is 520961 a debit or a credit card BIN?
It is recorded as debit, product level Platinum. Debit cards draw money directly from the cardholder's bank account, so checkouts and gateways often treat them differently from credit cards (fees, holds, recurring billing).
How many digits does a card with BIN 520961 have?
Mastercard card numbers have 16 digits, and the security code is a 3-digit CVC2 on the back. The first six digits are the BIN, the last digit is the Luhn check digit, and the digits in between identify the account.
Can I generate test card numbers with BIN 520961?
Yes. Open the generator with this BIN to create Luhn-valid numbers with expiry dates and CVVs for testing forms, validation and BIN-based rules. They are test data: not issued by South American International Bank Curacao, linked to no account and declined by real payment systems.
Does a BIN tell me whether a card is valid?
No. A BIN describes a range of card numbers — network, issuer, country and product — not a particular card. Whether a card exists or can be charged is known only to the issuing bank. To check the format of a full number (length and check digit), use the card validator.
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.
