Prefix for Tagged Release & Untagged Code

Tag Prefix and Agency Prefix Codes are used to aid in management and tracking of release groups. 

• Tag Prefix is the first two characters of the coded wire tag for a release group.
• Agency Prefix Code is the 2 character code following the “!” character for an untagged release group.

At this time BLANK Wire releases are recorded using the Agency Prefix Code for untagged releases.

To determine the disposition of recovered tag codes, refer to the associated contact for the tag prefix(es).

Note: During the 2015 RCMT meeting, ADFG, CDFW, and DFO-Canada reconfirmed the return of recovered / coded-wire tags returned by their agencies for an archival period of 5 years. Please contact the below representative for instructions on returning these tags. For details you can view Appendix C in the RCMT 2015 Meeting Minutes (go to Regional Committee on Marking and Tagging webpage to access the 2015 meeting minutes).
