卡号网 (chakahao.com) positions itself as a lookup platform for bank card number attribution, opening-bank CNAPS codes, bank card BINs, and related basic banking data. Based on the captured content, it offers bank card location/issuing-bank lookup, an opening-bank CNAPS code database, a comprehensive bank card BIN directory, corporate account opening-bank attribution lookup, passbook account bank lookup, and extensions such as database services, APIs, membership-based queries, and online batch lookup.
In terms of service type, this is not a payment acquiring or wallet product, but rather a “basic banking data identification tool” for payment, finance, and risk-control scenarios. Its bank card lookup does not require entering the full card number; the last four digits can be replaced with 0000. The site lists many banks, including Industrial and Commercial Bank of China, Agricultural Bank of China, China Construction Bank, China Merchants Bank, China CITIC Bank, China Everbright Bank, Postal Savings Bank of China, Shanghai Pudong Development Bank, China Guangfa Bank, and Ping An Bank. It also includes local banks, village and township banks, and some BIN examples related to international card schemes. On the API side, the website describes its service as “simple, fast, and secure,” and mentions capabilities such as an independent database, synchronized updates, cloud-based lookup, and batch task submission. However, it does not provide API documentation, authentication methods, rate limits, or SLA details.
The text does not disclose transaction rates, membership pricing, API call fees, database licensing costs, or settlement timing. These fields are critical for payment-related customers when assessing total cost. On the compliance side, the page does not explain data sources, authorization mechanisms, privacy protection, licenses, or filing/registration information. As a result, enterprise procurement would still need to separately verify the legality of its data, update frequency, and service agreement.
The advantages are its multiple query entry points, covering segmented data such as bank card BINs, CNAPS codes, corporate accounts, and passbooks, along with support for batch processing and API access. It is suitable for pre-payment verification by finance teams, issuing-bank identification before payment routing, and backend data cleansing. The drawbacks are limited transparency around commercialization, with no clear pricing, after-sales support, compliance information, or API technical details, making it difficult to directly assess stability and enterprise-grade usability.
It is better suited for developers, payment operations teams, corporate finance departments, and data cleansing teams as an auxiliary lookup tool or basic data source. It is not suitable as a complete payment processing solution. Access from China cannot be determined from the captured text and is marked as unknown. If alternatives are needed, consider bank card APIs from data aggregation providers, official bank CNAPS code lookup tools, or BIN identification services provided by UnionPay/payment institutions.
