Document Job Numbers
Job numbers are assigned to all material reproduced by the United
Nations and are registered in the Documents Retrieval and Information
Tracking System (DRITS). A unique job number is assigned to each
language version of a document. Job numbers appearing on documents
issued at UN Headquarters (New York) consist of the last two digits of
the year and a serial number corresponding to the order of submission
of the manuscripts to the Documents Control service. Job numbers
appearing on documents issued at other UN offices are preceded by a
letter or letters designating the location.
numbers printed on documents issued at:
New York have no
Geneva have prefix «GE»;
Vienna have prefix «V»;
Rome have prefix «R»
The job number usually appears on the lower left corner of the first
page of the document, along with a barcode. Sometimes it appears on the
second page, last page, or back cover of a publication.
Job numbers are used as unique document identifiers for the purpose of
transferring UNBIS metadata to the Official Document System (ODS) so it
is important that they are recorded correctly in tag 029.

Recording UN Document Job Numbers in tag 029
code JN is always entered in subfield $a.
The job number should be entered in subfield $b
in the same form in which it is recorded in ODS (e.g. N0059696 or G0232067) even though it may
appear on the document in another form (e.g. 00-59696
The job number recorded in subfield $b is
always followed by a space and a capital letter indicating the language
version of the document. It is important that the letter following the
job number corresponds to the language version of the document so that
the document title will display correctly in ODS.
a document is reprinted or reissued with the same document symbol but a
new job number, replace the earlier job number with the new one.
[Prior to Mar. 2009, the new job no. was added in new 029ab field preceding the earlier job no.]
[Prior to 1992, job
numbers were not recorded in UNBIS]
