Frequently Asked Questions

You can register your business name via the Oklahoma Secretary of State (SOS) SOSDirect Portal (click here to visit).

Useful information:

– In Oklahoma, you have options for the registration of a trade name or a fictitious name.

To register your business name, you will need to go through the following steps:

– Download and fill out all of the required forms here.

– Decide whether you’re going to use your given name for the company or if you’re going to register a trade name.

– Trade name registration is mandatory and your choice will have to be approved by the Oklahoma Secretary of State.

– To complete the process successfully, you’ll need a full set of documents that include licenses, permits, proof you meet zoning requirements (when applicable), building permits, etc. These vary depending on the industries and the activities your company will engage in. The Oklahoma Business Registration system will give you a complete list of the requirements.

– You will also need an employer identification number (EIN), a business bank account and proof of tax payment.

Finally, if you want to legally protect your name 100 percent, you will need to do trademark filing. This will keep companies in Oklahoma and other parts of the US from using the title.

There are strict rules and regulations when it comes to what an acceptable Oklahoma business name is. A title that has been registered by another business entity and is already in use cannot be registered a second time. To register a business name successfully, you will have to make sure your choice is distinguishable from other entries already on record.

It’s a good idea to register a business name that isn’t too similar to a title already on record. Federal laws and trademark protection could eventually get you into legal trouble, even if the name is not 100 percent identical.

Take some time to modify an existing idea or come up with a completely new one as a way to distinguish your Oklahoma business.
