When setting up a company or any business, you need to register a business registration certificate:
Business registration certificate means that all business organizations (whether limited companies, sole proprietorships or partnerships) must register with the business registration office under the Inland Revenue Department, and registered businesses must pay registration fees before they can obtain business registration certificates. (Information from Baidu Encyclopedia)
Therefore, the business registration number can be said to represent the identity of the company, just like the ID number on the personal ID card.
And by the way, your examples are all registered numbers in the old format, but from 20 19+00+00+ 1, a new format (consisting of 12 digits, as shown in the figure) has been adopted.
The picture comes from the internet.
For example: waybridge sdn.bhd.201701041440 (125513-p).
(During the conversion, the old and new formats can coexist.)
I don't quite understand this, and I only answered it after doing my homework temporarily. I hope to adopt it ~
