常见问题

What is a BIN or IIN number?

A BIN (Bank Identification Number), also called an IIN (Issuer Identification Number), is the first 6 to 8 digits of a payment card number. It identifies the card network (such as Visa or Mastercard), the issuing bank, and the card program (credit, debit, or prepaid). Modern cards use 8-digit BINs under ISO 7812.

How many banks are covered for Japan?

We track BIN ranges for 166 banks and card issuers with operations in Japan, covering 34,568 BIN ranges in total.

How do I look up a Japan bank BIN?

Select any bank from the grid on this page to see its full list of BIN ranges, card types, and supported networks. You can also enter the first 6 to 8 digits of any card directly into the lookup tool on our home page for an instant result that includes bank name, card brand, type, and validity.

Which banks issue the most BIN ranges in Japan?

Among the issuers tracked here, SUMITOMO MITSUI CARD COMPANY, LTD. (2,939), MITSUBISHI UFJ NICOS CO., LTD (2,305), MITSUBISHI UFJ NICOS CO., LTD. (1,949), CREDIT SAISON CO., LTD. (1,853), and DC JAPAN (1,406) hold the largest BIN portfolios. Note that some of these totals are combined across every country the issuer operates in, since not every source registry breaks BIN counts out by country.

How can I tell if a BIN is for a credit or debit card?

The Type column in each bank's BIN table shows whether the range is assigned to a Credit, Debit, or Prepaid card.

Why is the Category field hidden?

Category (for example Standard, Gold, Platinum, or Business) is visible to all free BINSearchLookup accounts. It is hidden on the public preview so anyone can browse BIN ranges freely, while the full card-program details remain protected against bulk scraping.

Is this BIN data updated regularly?

BIN assignments change as banks add or retire card programs. BINSearchLookup refreshes its dataset on a rolling basis from card network range registries and issuer disclosures. The last-verified date shown on each bank page reflects when that specific page was last checked. Full sourcing and cadence details are on our methodology page.

Can this page verify if a specific card is active or fraudulent?

No. A BIN identifies the issuer and card program, not an individual account or cardholder. To check whether a specific card number is valid and active in real time, for example for fraud screening, use the free lookup tool or API on our home page. This directory lists BIN ranges only.

What are BIN lookups used for in Japan?

Merchants and payment processors use BIN lookups for fraud detection (for example, flagging cards issued in unexpected regions), transaction routing, card verification during checkout, surcharge eligibility checks (credit vs. debit), and compliance screening. Developers also use BIN data for payment gateway integration testing.

数据来源与局限性

本页面的 BIN 和发卡机构数据来自卡组织号段登记信息及发卡机构公开资料的汇总,发布前经过交叉核实。BIN 仅能识别发卡机构和卡片项目,无法识别具体持卡人或账户,因此本页面无法确认某张具体卡片是否开通、已注销或已获交易授权。

本页面根据我们在Japan登记在册的 BIN 号段列出相关银行。如需实时核验某个卡号,请使用我们首页的查询工具。完整的数据来源与更新周期请见方法说明页面。
