For Delaware LLCs formed and maintained through Harvard Business Services, Inc., the state of Delaware's public record will, therefore, contain no information about your LLC's members and/or managers. 100% of your Delaware LLC is not on the public record, making Delaware one of the best states for LLC privacy.

The reason is that Delaware has a well-respected and established corporate court system as well as business-friendly tax, legal and regulation policies.

The Delaware state file number is the number that the state of Delaware issues to each new company at the time of formation. Your company file number will be formatted with seven numbers; for example, 1234567. Each new Delaware company will have a state file number one digit higher than the company before it.
