Management Domain Name

An organization seeking registration of management domain names should contact ANSI to obtain a Request for Registration application form. Upon request for an ADMD or PRMD, ANSI will submit the MHS-MD name to a three-month public review period in their bi-monthly publication Standards Action before the registration is approved.

The name of a management domain must conform to the syntax below:

Attachment A
Character Sets
from Operating Guidelines for Registrars
Revision 3, 13 December 1992

Table B-1. Printable String

Source: CCITT X.208. Table 5

Table B-2. Numeric String

Source: CCITT X.208, Table 4
Note: Numeric String is a subset of Printable String

An ADMD name registered by ANSI in the MD register is unique within the US and if used with countryName=us in an Originator/Recipient (O/R) address, the O/R address is globally unambiguous. If an originator wishes to operate an ADMD in another country, for example Canada, it must register in Canada to use its name with c=ca.

For PRMDs, if countryName=us and admdName =" ", the O/R address is globally unambiguous. If the name is to be used with another country in the O/R address, the name must be registered within that country.

Forever. However, ownership of MHS-MD names may be transferred and they may be suppressed at the request of the registered organization. There are also provisions for changing registration information about the "owner" to accommodate name and address changes as may occur.

The Organization Name Register and the MHS-MD Register are separate registers in the U.S. An organization may wish to register in either or both registers (with the same or different alpha-numeric names). Numeric names are only provided by the Organization Name Register. An organization wishing to use an alpha-numeric for an MHS-MD name needs to register this name in the MHS-MD Register.

Completed applications should be sent to ANSI, at the following address:

Henry Cheung
Registration Coordinator, ANSI
1180 Avenue of the Americas,  New York, NY 10036

Applications can also be faxed to the following: 1.212.398.0023.

The fee should accompany the application. ANSI accepts the following as payment: check, money order, American Express, Mastercard & Visa.

Note: Applications cannot be processed without the accompanying fee. If the application is faxed and the organization wishes to pay by check, the Registration Coordinator will hold the application until such fee is received. The same holds true for applications sent with a purchase order.
