Use Instructions
 As of the approval date, this data element 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 six-digit alphanumeric codes assigned by the Washington Office, Division of Realty, to organizational units, areas, or project sites over which the Service has some type of jurisdiction. Each organizational unit, area, or project site should have a unique IFWS number; however, there are a few instances where the same IFWS number has been assigned to more than one unit.   Therefore, please contact the Data Steward identified in this standard prior to using duplicate IFWS numbers in any new or existing data files.    

To ensure compliance with the Service Information and Technology Architecture (SITA), 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.

Whenever possible, the IFWS number should be used in conjunction with the official Organization Code and Organization Name.
