ETSI Assigned ASN.1 Object Identifiers

Common Domain

The ETSI Secretariat assigns and registers object identifiers under the common domain.  Each request for a new object identifier in this domain must come from an ETSI Technical Body. Each Technical Body is responsible for  the management and assignment of object identifiers under its assigned node, and each request for a new node must identify the ETSI deliverable which describes the structure and use of the sub-tree under the requested object identifier

To request an object identifier under this node, please send your request to

The following ASN.1 object identifiers have been registered under the Common Domain:

Name and Value Technical Body ETSI deliverable describing structure Date allocated
mobile-domain(0) 3GPP (Note) ETR 091 November 1992
in-domain(1) SPAN ETR 090 June 1993
etsi-library | securityDomain(2) SPAN / SEC ETS 300 655 / ES 201 671 March 1997
service-function(3) SPAN EG 201 189 June 1998
bran-domain(4) BRAN TR 101 764 June 2000
its-domain(5) ITS TR 102 707 February 2009

For example, the assigned Object Identifier for the IN Domain is: itu-t(0) identified-organization(4) etsi(0)  in-domain(1).

NOTE:  mobile-domain(0) was originally allocated to TC SPS, but was then given to TC SMG, and is now inherited by 3GPP. All Object Identifiers assigned under mobile-domain(0) can be found at the 3GPP ASN.1 Object Identifier web pages. All requests for object identifiers under the mobile-domain(0) are handled by ETSI's Mobile Competence Centre support team for 3GPP. Send your requests to

ETSI Deliverable Domain (0 4 0 128...)

Each ETSI deliverable has a unique number and is the responsibility of one technical committee.  Therefore, for each ETSI deliverable, a unique object identifier exists and can be used without any further registration.

The object identifier tree value for a given ETSI deliverable is derived by deleting the first digit of its document number (and omitting leading zeroes).
