Use Instructions
As of the approval date, will be used in any new automated system, data set, database, or information application, including new Geographic Information System (GIS) data and applications. This data element will also be used in any major modifications to existing systems or versions of these data-related items that use the literal codes assigned by the Washington Office, Division of Realty, to organizational units, areas, and project sites on Service-owned lands. Each organizational unit should have a unique literal code; however, there are a few instances where the same literal code has been assigned to more than one unit. Therefore, please contact the Data Steward identified in this standard prior to using duplicate literal codes in any new or existing data files.

Service staff are strongly encouraged to utilize this data element in existing systems, data sets, databases, and information applications. Where existing systems and data-related items are not in compliance, they should be modified to achieve compatibility and implement this data standard.

The Literal codes should always be used in conjunction with another data element, such as the IFWS Number or the official Organization Code
