Sole Proprietor EV Application

Sole Proprietorships and Their Impact on Extended Validation for Code Signing Qualification 


Extended Validation Code Signing Certificates (EVCS) provide the highest level of validation available. The process of getting approved goes beyond the standard validation methods. Acquiring an EVCS helps boost organizational confidence by providing industry-leading identity assurance. For example, once issued, EV Code Signing Certificates receive automatic trust from Microsoft, bypassing the trust warning that unsigned apps get. 


Sole Proprietor Challenges:

This practice creates a validation problem. Without proof of existence with a city, county, state, or federal agency, Sole Proprietorships will not meet the requirements for Extended Validation.

This form requires either a notary seal with a currently registered notary, a registered CPA seal, or an active attorney signature. Combined with the other validation steps, the additional form adds a layer that will suffice for compliance, auditing, and security purposes.
