Can I search SOS records by TIN or EIN?

No. Secretary of State (SOS) registries generally do not expose Tax Identification Numbers (TINs) or Employer Identification Numbers (EINs).Cobalt’s TIN Verification process separately confirms whether a business name and EIN combination matches IRS records and returns a match status (match, mismatch, or no record).(Note: EINs are a type of TIN specific to businesses.)
