Similar to today’s technology requiring the memorization of a lot of different numbers and passwords, businesses also require an array of numbers and passcodes. 

As part of the filing of an LLC, the Secretary of State assigns a document number to identify the actual, filed articles. The Secretary of State also assigns a business its charter number, which helps identify the organization. And usually following an entity’s establishment, a business will get an employer/tax identification number, also called an EIN.
