A field may be used to note the number itself, if it can not be recorded in any of the fields 010 to 071 which deal with identification numbers, or it can be used to comment on a particular number. If notes about more than one number are to be recorded, each is entered in a repeated field 301.
An identification number may be preceded by a corresponding introductory phrase, e.g. "Contract number:" or "Ref. nr.:".
