We recommend tags are purchased as birth tags — in other words, with a visual ID format of 12345-11 (no year code). 

The tags must only be used for the NAIT number they were purchased for.  

Where there are multiple stock companies as PICAs at a saleyard, each PICA will need to purchase their own tags for their own NAIT location number. Tags cannot be shared between stock companies. 

Where the saleyard owner is the sole PICA, the saleyard owner will need to purchase tags for use on all animals at the sale. 

It is not acceptable for the saleyard owner to buy tags for a location if they are not the appointed PICA.
