How to find your company number

The IUB has assigned a company number to each company in its database. To find that company number, run a Company Search from the IUB’s electronic filing system. On the Company Search page, fill in the company name and click on search. If you are not sure how the company name appears in the IUB database, you may search by industry type to get a list of all the companies in that industry. If the search results return more than one company, click on Summary next to your company. The company summary page will include the company number as part of the information about the company.
