Research local Wisconsin businesses.
When researching the tax identification number of a business operating in the state of Wisconsin, you need basic identifying information about the business. It isn't necessary to go through a state website to find a Wisconsin's business' tax identification number. A number of local and online sources provide tax identification look-up services. Once you have the business' tax identification number, you can easily obtain other information recorded in state business records, such as the owner type and date of commencement.
Instructions
1. Contact the business owner by telephone. Find the business' dedicated telephone number in a local business directory. Ask for the business' nine-digit tax identification number, which is public record. For a large corporation, contact the human resource manager. Ask him to provide you with the number.
2. Find the business' tax identification number using its registered business name, which you can find on a receipt, invoice, marketing material, phone directory or business website.
3. Plug the business' name (or the first few letters) into a free online look-up system. Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system is one example. Melissa Data is another; however this system is designed specifically for nonprofit businesses. Each system is available to the public and provides updated information about Wisconsin businesses.
4. Enter the zip code for the business' corporate office, not the local office. Find contact information for the corporate office on the business' dedicated website or inquire with local management.
