31 C.F.R. § 306.10
The registration used must express the actual ownership of a security and may not include any restriction on the authority of the owner to dispose of it in any manner, except as otherwise specifically provided in these regulations. The Treasury Department reserves the right to treat the registration as conclusive of ownership. Requests for registration should be clear, accurate, and complete, conform with one of the forms set forth in this subpart, and include appropriate taxpayer identifying numbers. The registration of all bonds owned by the same person, organization, or fiduciary should be uniform with respect to the name of the owner and, in the case of a fiduciary, the description of the fiduciary capacity. Individual owners should be designated by the names by which they are ordinarily known or under which they do business, preferably including at least one full given name. The name of an individual may be preceded by any applicable title, as, for example, Mrs., Miss, Ms., Dr., or Rev., or followed by a designation such as M.D., D.D., Sr., or Jr. Any other similar suffix should be included when ordinarily used or when necessary to distinguish the owner from a member of his family. A married woman's own given name, not that of her husband, must be used, for example, Mrs. Mary A. Jones, not Mrs. Frank B. Jones. The address should include, where appropriate, the number and street, route, or any other local feature and the Zip Code.
