Va. Code § 8.01-216.13
Any civil investigative demand issued under this article may be served by an investigator, or by any person authorized to serve process on individuals in the Commonwealth.
Any such demand or any petition filed under this article may be served upon any person who is not found within Virginia in such manner as the Rules of the Supreme Court of Virginia or the Code of Virginia prescribe for service of process outside Virginia. To the extent that the courts of this Commonwealth can assert jurisdiction over any such person consistent with due process, the courts of this Commonwealth shall have the same jurisdiction to take any action respecting compliance with the provisions of this article by any such person that the court would have if such person were personally within the jurisdiction of the court.
Service of any civil investigative demand issued under this article or of any petition filed under this article may be made upon a partnership, corporation, association, or other legal entity by (i) delivering an executed copy of such demand or petition to any partner, executive officer, managing agent, or general agent of the partnership, corporation, association, or entity, or to any agent authorized by appointment or by law to receive service of process on behalf of such partnership, corporation, association, or entity; (ii) delivering an executed copy of such demand or petition to the principal office or place of business of the partnership, corporation, association, or entity; or (iii) depositing an executed copy of such demand or petition in the United States mail by registered or certified mail, with a return receipt requested, addressed to such partnership, corporation, association, or entity at its principal office or place of business.
Service of any such demand or petition may be made upon any natural person by (i) delivering an executed copy of such demand or petition to the person, or (ii) depositing an executed copy of such demand or petition in the United States mail by registered or certified mail, with a return receipt requested, addressed to the person at the person's residence or principal office or place of business.
A verified return by the individual serving any civil investigative demand issued under this article or any petition filed under this article setting forth the manner of such service shall be proof of service. In the case of service by registered or certified mail, such return shall be accompanied by the return post office receipt of delivery of such demand.
