Datamars is a global leader in animal identification. The Irish affiliate, Datamars Ireland is now an approved supplier of cattle ear tags for the Republic of Ireland. We offer simple, high-quality ear tags that are designed to last.

Mandatory Bovine EID

For your information, as announced by the Minister of Agriculture, mandatory bovine EID will be implemented in two stages:

  1. From 1st January 2022 all approved bovine tag suppliers will be required to supply an EID tag with all new tag orders. Each new tag set will include one EID tag and one tissue tag. EID tags will be white in colour. The colour of conventional and tissue tags will remain yellow.

  2. From 1st July 2022 it shall be a legal requirement on herd keepers to officially identify all new-born calves with a tag set containing an EID tag.

  3. All calves born on or after the 1st July 2022 must be tagged and registered with a set containing a white EID tag.

In line with these new rules, we will no longer be in a position to supply non-EID sets from 1st January 2022 and would like to remind farmers that any unused non EID sets will be unusable from 1st July 2022.


Many thanks for your ongoing support and understanding.
