If you own a company, you must obtain a 9-digit tax identification number issued by the IRS. With this number, you can open a bank account on behalf of your company, apply for a credit card, get business licenses and grants, as well as make all your tax declarations. If you have a Social Security Number (SSN), you are not required to obtain an EIN number. However, keeping your SSN number secure, obtaining a number independent of your company-specific ID number and performing your banking transactions with this number can prevent some problems you may encounter in the future. An application for an EIN must be made to the IRS by mail or online. If you want to obtain an EIN, you can fill out our information form. We will start your EIN process by contacting you as soon as possible.
