When you’re starting a business, things can get quite complicated. There are always numerous processes to take care of and documents to prepare. And that is if you are lucky.

If you want to run a local limited company in Hong Kong, there are a few steps you need to complete. First, you need to register with the Companies Registry to get limited company status. Next, you have to register with the Business Registration Office to be able to do business in Hong Kong.


Therefore, your company will have two important numbers: Company Registration Number and Business Registration Number. These two numbers are necessary later on every time you sign legal documents such as when opening a bank account, renting office space, or signing a contract.


Nonetheless, the difference between the business registration number and company registration number often results in confusion. A lot of business owners confuse these two, as they are not really sure what each of them looks like and why they exist in the first place.

Luckily, this article will explain everything you need to know about these two important numbers for every company based in Hong Kong.

What Is the Company Registration Number Hong Kong?

Just like registering a business and registering a company in Hong Kong are not the same thing, there is also a difference between the business registration number and company registration number (CRN).


The company registration number is something like your company’s social security number. Along with your company’s name and business registration number, it is one of the most important means of identification for your company.


It serves as an official means of representing your company in future documents and government records. You should be able to find your CRN in the top left corner of the Certificate of Incorporation.

What Is the Business Registration Number?

Every business operating in Hong Kong requires a Hong Kong business registration number (BRN). This number is issued by the Inland Revenue Department (IRD) before a work location can be set up.


It is an 8-digit sequence at the front of your BR certificate number (e.g. 22222222-&&&-&&-&&-&). It is important to note that all the numerals of the BR number are used as an identifier equivalent to the tax identification number for entities.

Why do you need a business registration number?

The BRN follows a unique number assigned by the IRD, and it is actually your tax identification number (TIN). Therefore, this number is necessary for legal business operations and tax payment in Hong Kong.


Even though the difference between the company registration number and business registration number can be quite confusing, the entire incorporation process doesn’t have to be like that at all.
