Cattle Tags Australia: The Complete Guide
Share
Cattle tags look simple enough until you sit down to order them, then you're suddenly staring at NLIS, eID, breeder, post-breeder, year colours, letter codes and half a dozen sizes. This guide pulls the whole lot together in plain English, so you can work out exactly what your operation needs and get on with it.
Farm & Acre Co supplies NLIS cattle tags, visual management tags and one-piece feedlot tags from Allflex, FOFIA and Leader, shipped Australia-wide from Queensland. If you already know what you're after, head straight to the range. If not, read on, by the end you'll know your breeder from your post-breeder, and why 2026 calves are wearing orange.
The Three Main Types of Cattle Tags
Most cattle producers run a mix of two tag types, an NLIS electronic tag for compliance and a visual tag for day-to-day management. Feedlots and live exporters add a third: the one-piece feedlot tag. Here's how the three stack up.
| Tag type | What it is | When you use it |
|---|---|---|
| NLIS electronic (eID) | Two-piece tag with an RFID chip linked to your PIC | Mandatory & before cattle leave your property |
| Visual / management | Printed plastic tag you can read from a distance | Optional, on-farm ID, mobs, year groups |
| Feedlot one-piece | Self-piercing single-piece tag | Short-term ID, feedlot entry, live export, mob marking |
NLIS Electronic Tags (eID)
This is the non-negotiable one. Every beast that leaves an Australian property needs an NLIS-accredited electronic ear tag. Inside the tag is a small RFID chip carrying a unique 16-digit number, and that number is linked to your Property Identification Code (PIC) on the NLIS database. Saleyards, abattoirs and receiving properties scan the tag to record each movement, that's how Australia traces cattle from the property they were born on right through to processing.
A few quick rules that catch people out:
- The NLIS tag goes in the right (offside) ear. That's the standard right across the country.
- The tag is tied to your PIC, so you'll need your PIC number handy before you can order.
- NLIS is administered by each state, and the finer details differ between them. If you're unsure exactly what applies on your place, your state's agriculture department is the right port of call.
If you want the full plain-English rundown on how the NLIS system actually works, the database, the scanning, what happens when you buy and sell, we've stepped through it in our NLIS tags explained guide.
Visual Management Tags
Visual tags (also called management tags) are the big coloured plastic tags you can read from across the yards. No electronics, just print. They're optional, but most producers wouldn't run cattle without them, because a tiny electronic number tells you nothing from ten metres away.
A visual tag can carry whatever you want printed on it: animal number, year letter, mob or paddock code, breed, joining group, even your property name. They're a two-piece design, a printed female front and a male button that locks through the ear, and they come in sizes from a small button right up to a Super Maxi panel you can read across a paddock.
The thing to remember: a visual tag never replaces an NLIS tag. It works alongside it. The NLIS tag keeps you compliant; the visual tag does the day-to-day work in the yards.
One-Piece Feedlot Tags
Feedlot tags are single-piece, self-piercing tags built for speed. There are no male and female halves to line up, load, punch, done. That makes them the pick for high-volume, short-term jobs: feedlot induction, live export, mob marking at processing time. Both Allflex and FOFIA make a one-piece feedlot tag, and you'll find them in our feedlot cattle tags collection.
They're not a substitute for an NLIS tag either, they're a fast working ID that sits alongside the compliance tag.
Breeder vs Post-Breeder Tags: The 30-Second Version
This one trips up plenty of people, so here's the short version:
- Breeder tags (white) are for cattle born on your property. You tag your own calves with white breeder tags before they leave.
- Post-breeder tags (orange) are for cattle that weren't born on your place, bought-in animals that have lost their tag, or stock that needs re-tagging against your PIC.
Day-to-day, that's all there is to it: born here = white, came from somewhere else and needs a tag = orange. There are a few wrinkles around when each type is allowed, and we've unpacked them properly in our breeder vs post-breeder tags guide if you want the detail.
Cattle Tag Year Colours and Letter Codes
Australia runs a national year colour rotation for cattle tags. Each year has a set colour and a matching letter code, so you can age an animal at a glance from the colour of its visual tag, no yard book required. It's one of those systems that sounds like bureaucracy until you've used it for a season, and then you wonder how anyone manages without it.
The year colour table
| Year | Colour | Letter |
|---|---|---|
| 2022 | Red | R |
| 2023 | Sky Blue | S |
| 2024 | Black | T |
| 2025 | White | W |
| 2026 | Orange | X |
| 2027 | Light Green | Y |
| 2028 | Purple | Z |
| 2029 | Yellow | A |
| 2030 | Red (cycle repeats) | B |
So calves born in 2026 wear orange tags with the letter X, and the 2027 drop will be light green with a Y. From 2030 the colours come back around again, starting with red.
Plenty of producers print the year letter as the first character of the animal number, X001, X002, X003 and so on for the 2026 calves. One glance at the tag tells you the year and the individual animal.
Year colours vs NLIS colours: don't mix them up
Here's where people get tangled. The year colour rotation applies to visual management tags. NLIS electronic tags follow their own colour rule, breeder tags are white and post-breeder tags are orange, every single year.
So in 2026 an animal might carry an orange visual tag (the year colour) and a white NLIS breeder tag at the same time, and that's exactly right. An orange NLIS tag always means post-breeder; it's got nothing to do with the 2026 year colour. If you want the full colour-by-colour breakdown, our NLIS tag colours by year guide covers it properly.
Custom Printing Options
Most visual tags, and plenty of NLIS tags, can be custom printed before they ship, and it's worth doing. Blank tags are cheap to buy and expensive to live with; printed tags do the record-keeping for you.
What you can have printed
- Laser printing: up to 3 lines of engraved text that won't rub off or fade. The most common setup.
- High-contrast printing: bolder, darker print for better readability at distance. Handy on lighter tag colours.
- Back printing: extra information on the reverse of the tag, so you're not cramming everything on the front.
- Custom numbering sequences: for example X001 through X250 for this year's calf drop, or a continuation of last year's run.
A tip from experience: think about readability before you fill every line. Three short, bold lines beat five squashed ones every time, you're reading these tags from the crush or across a pen, not up close. For the full set of print layouts, sizes and options (including the popular Maxi tags), see our custom cattle tags guide.
Choosing the Right Size and Type
Visual cattle tags run from Mini buttons up to Super Maxi panels. Rather than memorising the whole size chart, work through three questions:
- How old are the animals? Calves get Mini or Small tags, small ears, small tags. They can be re-tagged with bigger gear later, or you can fit a Large from the start if they're staying on your place.
- How much do you want printed? One animal number fits anything from Medium up. Three lines plus a property name wants a Maxi or Super Maxi.
- How far away will you read it? Across a crush, Medium is fine. Across a feedlot pen or a paddock, go Maxi.
If you're not sure, Large is the most popular all-round size for adult cattle in Australia, big enough to read easily, small enough to retain well. Studs, dairies and feedlots tend to step up to Maxi for the extra print space.
For the deeper technical detail, tag materials, retention rates, two-piece versus one-piece construction and how to keep tags in ears for the long haul, our bovine ear tags guide goes through the lot.
Applicators: The Short Version
Tags don't put themselves in. Two rules cover most of what you need to know:
- Match the applicator to the tag brand and type. Two-piece tags load onto a pin, and each brand's tags are shaped for that brand's applicator, an Allflex tag goes on with an Allflex applicator. Forcing mismatched gear is how pins get bent and tags end up in the grass.
- One-piece feedlot tags use their own style of applicator: simpler again, built for speed.
There are also battery-powered taggers on the market that fire the tag through in a split second, genuinely handy for big mobs and nervous cattle. One thing to be clear on: a battery tagger is an applicator only. It applies standard visual, fly and feedlot tags, it doesn't apply NLIS or eID tags, and it doesn't record anything.
We've put the full rundown, which applicator suits which tag, loading, placement and technique, in our ear tag applicator guide, and the gear itself lives in our applicators and accessories collection.
How Ordering Cattle Tags Works
Ordering tags isn't complicated once you know what you'll be asked for. Have these six things ready:
- PIC number: your Property Identification Code. Required for NLIS tags.
- Tag type: NLIS electronic, visual, a combo of both, or feedlot one-piece.
- Size: Large is the safe default for adult cattle if you're unsure.
- Colour: usually the year colour for this year's calves, but management tags can be any colour you like.
- Print details: what text and numbering you want on each line.
- Quantity: count the calves you expect, then add a margin for losses and late arrivals.
Pricing works a little differently depending on the brand: Allflex pricing is listed on our site, FOFIA tags are quoted through a quick enquiry form, and Leader orders go through Leader's reseller arrangement. None of it takes long, and if you'd rather just tell us what you're running, we'll sort the rest.
All tag orders ship from our Queensland warehouse, Australia-wide. Custom-printed tags take a bit longer than blank stock because they're printed to order, worth factoring in ahead of calf marking rather than the week of. For the step-by-step on what the process looks like from order to letterbox, see our guide on how to order NLIS tags online.
FAQ
What colour are cattle tags in Australia for 2026?
Orange, with the letter code X. That applies to the visual year tags. NLIS breeder tags stay white in 2026, as they do every year, and post-breeder NLIS tags are orange regardless of the year.
Which ear does a cattle tag go in?
NLIS electronic tags go in the right (offside) ear. Visual management tags usually go in the left (nearside) ear, so the two are easy to tell apart in the crush.
Do I need both an NLIS tag and a visual tag?
Only the NLIS tag is mandatory, and only before the animal leaves your property. The visual tag is optional, but most producers run both because reading an electronic number across the yards isn't an option. Combo sets pair a matched eID and visual tag for the same animal.
Can I use cattle tags on sheep or goats?
No, sheep and goats use their own tag types and sizes, and their electronic ID requirements are phasing in differently by state. We stock sheep and goat EID tags from January.
What's the letter code for 2027 cattle tags?
Y, and the colour is light green. If you're ordering ahead for an autumn 2027 calf drop, that's the combination to print.
TL;DR: Quick Reference
- NLIS eID tags are mandatory before cattle leave your property. Right (offside) ear, linked to your PIC.
- Breeder = white (born on your place). Post-breeder = orange (bought-in or re-tagged). Same colours every year.
- Year colours are for visual tags: 2026 = Orange = X, 2027 = Light Green = Y. The cycle repeats from 2030.
- Visual tags are optional but worth it: custom printing up to 3 lines, plus high-contrast and back printing.
- Large is the most popular size for adult cattle; Maxi for serious print space; Mini/Small for calves.
- Feedlot one-piece tags are for fast, short-term ID, they don't replace NLIS tags.
- Match your applicator to the tag brand. Battery taggers apply visual, fly and feedlot tags only, never NLIS/eID.
- Orders ship from Queensland, Australia-wide. Have your PIC ready for NLIS tags.
