What are the benefits of matched pair tags?

Preparing to add Electronic ID tags in your herd or take a Tissue Sample to collect genomic data on your cattle? Make the process easier with matched pair combinations.

Matched pair combinations are a set of devices with matching management codes. These can come in a variety of combinations including a visual (VID) tag, an electronic (EID) tag, and a tissue sample unit (TSU). See an example image below detailing how the three devices are permanently linked.

Do you already have a list of tag numbers you want printed on your custom visual tags? Simply email the spreadsheet file to to include it with any order you place or to have us create a cart for your review and to check out.

If you do not currently use the herd management software CattleMax, you can learn how to manually create an Excel spreadsheet with your custom numbers.

If you are a CattleMax member, use CattleMax to generate a file of your tag numbers.

Allflex offers the ability to download and print an electronic list of the EID numbers you received with your order. A benefit of ordering with us at is we automatically email your EID spreadsheet to you when your order ships.

You can link visual IDs and EID records together just by going through a few steps in CattleMax to download the EID spreadsheet lists directly into the software. The records are automatically linked (if the EID spreadsheet list includes visual IDs) or you choose the animal record to link for each EID entry. This way, your time at the chute can be spent on getting the tags in their ears and not needing to worry about writing down which EID number goes with each cow!

If you already have a CattleMax account, learn how to import those EID tag numbers to pair with your visual tags.

If you are new to CattleMax, learn how to bulk add your animals then import your EID number to pair with your visual tags.
