It's true APHIS wants to move to 840 official IDs. Do you have links or more information about which states offer free 840 tags? Until Jeanne - Simme Valley mentioned New York, I had not heard of it. All the information about New York's program is on New York Agriculture and Markets. To my knowledge, my state only offers free Scrapie tags for small ruminants.840 tags are free in most states at least for the time being. The metal NUES tags are being phased out. In 2-3 years the metal tags will not be recognized as official ID.
