Delivery, for purposes of this paragraph, means handing a copy of the notice to the individual; or leaving a copy at the individual's office with a clerk or other person in charge thereof; or leaving a copy at the individual's dwelling house or usual place of abode with some person of suitable age and discretion then residing therein; or sending a copy of the notice addressed to the individual through the U.S. Postal Service by Registered Mail, Certified Mail or Express Mail delivery, or by third-party commercial carrier, for overnight delivery and obtaining a confirmation of receipt.

To corporations or entities.

Upon persons registered with the Bureau. In addition to any other method of service specified in paragraph (d)(1)(i) or (ii) of this section, notice may be made to a person currently registered with the Bureau by sending a copy of the notice of charges addressed to the most recent business address shown on the person's registration form by U.S. Postal Service certified, registered or Express Mail and obtaining a confirmation of receipt or attempted delivery.

Upon persons in a foreign country. Notice of a proceeding to a person in a foreign country may be made by any method specified in paragraph (d)(1) of this section, or by any other method reasonably calculated to give notice, provided that the method of service used is not prohibited by the law of the foreign country.

If service is made to an agent authorized by appointment to receive service, the certificate of service shall be accompanied by evidence of the appointment.

Waiver of service. In lieu of service as set forth in paragraph (d)(1)(i) or (d)(1)(ii) of this section, the party may be provided a copy of the notice of charges by First Class Mail or other reliable means if a waiver of service is obtained from the party and placed in the record.

Service of recommended decisions and final orders. Recommended decisions issued by the hearing officer and final orders issued by the Bureau shall be served promptly on each party pursuant to any method of service authorized under paragraph (d)(1) of this section.
