c-banken.com is a carrier-prefix lookup site for Japanese mobile and PHS numbers. According to the main content, it can identify the carrier with which a number was originally contracted based on the first 6 digits of the phone number, such as ドコモ, ソフトバンク, au, 楽天モバイル, and others. The site provides lists for 090, 080, 070, and 060 number ranges, as well as a “まとめて検索” bulk search feature and a mobile entry point.
Its core modules are quite focused: browsing carrier allocation tables by number range, entering a target number for quick lookup, and checking multiple numbers at once. The pages also describe the call-tone characteristics of different carriers, which can serve as an auxiliary clue after MNP number portability. It is important to note that the site explicitly states that results only represent the “originally contracted carrier.” If a number has been ported via MNP, the listed data may not match the current actual carrier, so it is not suitable for highly accurate real-time carrier identification.
The main content does not show information about fees, subscriptions, plans, trials, or payment methods. There is also no visible account system, team collaboration, permission management, third-party integrations, API, SLA, security compliance, or other common enterprise software capabilities. In terms of deployment, it appears to be a public web-based tool rather than a self-hostable or privately deployable SaaS platform.
Its strengths are a clear purpose, a low barrier to lookup, and a visible data update date, making it suitable for quick manual checks of Japanese mobile number ranges. Its limitations are that it is more of a utility website, lacking enterprise-grade data interfaces and service commitments. In addition, due to MNP, it cannot guarantee that the result reflects the current carrier.
It is suitable for customer service, operations, and data cleansing teams that need an initial judgment of Japanese number prefixes. If a business needs bulk, automated, real-time identification of current carriers, it should consider more specialized number validation or HLR-style API services. The main content does not provide information about access from mainland China, and the payment methods are also unknown.
