Title: Add support for storing DUNS data in the company identification field

Unfortunately I believe this is a breaking change. Per the documentation (OR106), the company identifier field is 10 digits long and can start with a 1, 3 or 9. An ICD of 1 signifies that the data represents an IRS Employer Identification Number (EIN). An ICD of 3 signifies that the data represents a Data Universal Numbering Systems (DUNS).
