Assigning Corporate Numbers Using Business Establishment Data

Last Updated: July 9, 2024

Corporate numbers are increasingly being utilized to streamline the management of transaction information.

However, since only one number is assigned per legal entity, managing data at the individual business establishment or store level using corporate numbers can be difficult.
Have you ever encountered this challenge?

We will introduce how uSonar can help you solve these challenges!

The Corporate Number is a unique code assigned by the government to registered corporations. It is promoted for use as a Data Cleansing and Matching code, as well as a means to verify the existence of a company (confirming whether it is a corporation guaranteed by the state). However, it is currently difficult to assign Corporate Numbers to specific business locations or branches. uSonar can assign Corporate Numbers even to business locations that were previously difficult to identify using only address or name information. Please check here for the implementation case study of MUFG Bank, Ltd.

What Is a Corporate Number?

The Corporate Number is a 13-digit number consisting of a 12-digit Corporate Registration Number plus a 1-digit check digit. It is assigned to corporations based on the Act on the Use of Numbers to Identify a Specific Individual in Administrative Procedures, which was enacted on May 24, 2013 (promulgated on May 31, 2013). After notification to the target corporation, it is published along with the trade name or name, and the location of the head office or principal office.

* The Corporate Registration Number is used for various purposes, such as obtaining a certificate of registered matters or omitting attached documents when applying for commercial or real estate registration.

The attribute information published with the Corporate Number consists of four items: (1) Corporate Number, (2) Trade Name or Name, (3) Trade Name or Name (Katakana), and (4) Location.
* The Trade Name or Name (Katakana) has been published as a registered matter since March 2018. In addition to these four items, English trade names and locations are also published, but these are items that only companies that request them will have registered.

Only one Corporate Number is assigned to the head office or principal office of a corporation. Corporate Numbers are not assigned to branches or business offices.

Therefore, There Are Challenges with Corporate Numbers
  1. Only data for registered addresses exists ⇒ Does not match data for business offices with headquarters functions
  2. Only assigned to the headquarters ⇒ Cannot manage by business office or store unit
  3. Does not match due to differences in notation from internal data ⇒ Requires correction of notation variations through cleansing

Case Study: Corporate Number Assignment Following Partial Amendment of the Installment Sales Act

Case Study: Corporate Number Assignment Following Partial Amendment of the Installment Sales Act

Mandatory assignment of Corporate Numbers aimed at strengthening merchant management.
Achieving high-precision assignment.

Background and Challenges

Following the partial amendment of the Installment Sales Act, it became necessary to assign Corporate Numbers to merchant data.

  1. We downloaded Corporate Number data in-house and performed matching, but it did not match at all.
  2. We thought about utilizing credit data since it already had Corporate Numbers assigned, but the match rate was only about 30%.

Solution

Utilizing the LBC Corporate Information Database, which covers all Corporate Numbers, to assign numbers with high precision.
  1. Achieved high-precision matching with merchant data by utilizing various knowledge, such as notation variations of company names and historical information on former names and mergers/acquisitions.
  2. Since head office and branch relationships are linked, matching is possible even if the registered address differs from the actual operational headquarters address.
