Bank Card BIN Lookup

Received a bank card number like 6226090847295831? Enter it into the search box, and the right panel instantly shows the issuing bank as China Construction Bank, the card type as a debit card, and the location as Beijing—this is a quick snapshot of what our Bank Card BIN Checker does.

What is a BIN Code?

The Bank Identification Number (BIN) refers to the first few digits of a bank card number, typically the first 6 digits, though some organizations have expanded this to 8 digits. The international standard ISO/IEC 7812 establishes the allocation framework for Issuer Identification Numbers (IIN). Under this framework, card networks like UnionPay and Visa assign exclusive BIN ranges to banks. For example, most UnionPay cards issued in mainland China start with 62, and a common BIN range for China Construction Bank debit cards is 622609.

For users, the BIN code acts like the "ID prefix" of a bank card. By just looking at the first few digits, you can determine which bank issued it and whether it is a debit or credit card. Our checker queries a public BIN database to match the card number with its issuing bank information.

How to Use This Checker

Once the page loads, you will immediately see the "Bank Card Number" input box and the search button next to it. The operation is simple:

Enter a complete bank card number (16 to 19 digits) into the input box. It supports UnionPay debit cards, credit cards, and some quasi-credit cards.
Click the "Search" button. The system will request backend data via an encrypted interface.
After about 1 second, an information card listing multiple fields will appear in the results area on the right or below.
The card displays the "Bank Name," "Card Name," "Type," "Province," "Card BIN," "Bank Abbreviation," and "Customer Service Phone" in sequence.
If you want to check another card, you can directly modify the numbers in the input box and click search again without refreshing the page.

Complete Example: Checking a China Construction Bank Debit Card

Let's walk through the process using the example card number 6226090847295831 (this is a public test card number and does not involve a real account).

Step 1: Paste 6226090847295831 into the bank card number input box and click "Search." Step 2: View the returned results:

Bank Name: China Construction Bank
Card Name: Long Card
Type: Debit Card
Province: Beijing
Card BIN: 622609
Bank Abbreviation: CCB
Customer Service Phone: 95533

Why did we get this result? Because the first 6 digits, 622609, are one of the BIN ranges assigned to China Construction Bank. After matching with the database, it automatically provided the corresponding issuing bank and the card product "Long Card" typically associated with this range. This result tells us that the provided number is a debit card issued by the Beijing branch of China Construction Bank. If telephone verification is needed, you can dial 95533 directly.

How to Interpret the Result Fields

Each field returned by the checker has a specific meaning. Understanding them can help avoid misunderstandings:

Bank Name & Bank Abbreviation: The full name and English abbreviation of the issuing bank, such as "China Construction Bank" abbreviated as CCB. This helps you distinguish between different banks, especially those with similar names.
Card Name: The name of the card product corresponding to the BIN range, such as "Long Card" or "Peony Money Link Card." Not all cards have a specific card name; some may show as "Unknown."
Type: Identifies the card type, usually categorized as "Debit Card," "Credit Card," or "Quasi-credit Card." Debit cards cannot be overdrawn, credit cards have a credit limit, and quasi-credit cards fall somewhere in between.
Province: This displays the location of the issuing bank's branch corresponding to the BIN range (i.e., the province or city of the account-opening bank), not the cardholder's actual residential address or the specific branch where the card was issued. For example, if the result shows "Beijing," it only means this BIN range is managed by the Beijing branch; the cardholder could very well have applied for it at an out-of-town branch in Guangzhou.
Card BIN: The actual BIN range (first 6 digits) matched by the checker. You can compare it to confirm if it matches the first few digits of the card number you entered.
Customer Service Phone: The bank's official customer service hotline, ready to dial at a glance.

Common Misuses and Pitfalls

Using a BIN code to look up a bank is very convenient, but many people have fallen into the following traps:

Treating BIN lookup as the sole method to verify card authenticity: Card numbers can be forged, and it is not difficult to obtain a real BIN code and generate a card number. True card verification requires a combination of magnetic stripe/chip transactions, CVV, and bank system validation. A BIN code alone cannot confirm a card is genuine.
Mistakenly believing "Province" is the cardholder's location: As mentioned above, the province field corresponds to the location of the account-opening bank when the BIN range was allocated. It does not represent the cardholder's registered residence or current address. If you apply for a card in a different city, the result will still show the province of the original BIN allocation.
Relying on outdated databases to identify newly issued cards: Banks continuously issue new co-branded cards or adjust BIN ranges, and database updates take time. If the query returns "Unknown" or the information does not match the physical card you hold, always refer to the bank's official information.
Performing unverified operations using the queried customer service phone number: Although the tool returns public bank customer service numbers, it is still recommended to double-check via the official website. This is especially important when you need to provide your card number, password, or verification code, to avoid being exploited by fake base stations or phishing websites.

Important Notes

This checker operates based on public BIN code allocation tables. There are a few limitations to keep in mind:

Does not support non-bank cards: Gift cards, prepaid cards, and some niche overseas card network cards may not be covered by the database.
Card number length must be sufficient: Entering fewer than 16 digits, or only the last few digits, may fail to locate the BIN code. Please try to provide the complete card number (up to 19 digits).
Queries do not involve privacy: The backend only processes the first few digits of the card number to match the BIN. It does not store the complete card number, nor does it access account balances, transaction records, names, or other personal information.
Results are for reference only: For financial decisions (such as reporting a lost card, transferring funds, or risk assessment), please rely on information provided by official bank channels. Special reminder: Do not use the checker for illegal purposes, and do not enter someone else's complete card number in an untrusted environment.

Typical Use Cases

Here are a few real-life moments when a BIN code lookup comes in handy:

Corporate Financial Transfer Verification
When company finance receives a supplier's corporate account card number, they can use a BIN code lookup before transferring funds to confirm the receiving bank is indeed the one stated by the supplier, avoiding refund delays caused by an incorrect account-opening bank.

E-commerce Return Fraud Prevention
After you apply for a return, the seller sends a card number asking for the refund to be sent there. A BIN code lookup reveals that the issuing bank of the card number does not match the bank claimed by the merchant. This is highly likely a scam, and you should stop the transaction immediately.

Finding a Lost Bank Card and Contacting the Owner
If you find a bank card on the street but are unsure which bank it belongs to, and it's inconvenient to hand it directly to the police, you can look up the BIN code. Then, call the bank's customer service and follow their instructions to turn it in or report it lost, protecting the owner's funds.
