What Are Livestock ID Tags?
Livestock ID tags are electronic ear tags that give each animal a unique identification number stored on an RFID chip. Farmers and ranchers use these tags to track health records, breeding data, vaccination history, and movement logs without relying on printed numbers.
Our FDX-B livestock ear tags operate at 134.2 kHz and follow the ISO 11784/11785 standard. Each tag contains an EM4305 or SIC7999 chip sealed in injection-molded TPU. The female tag measures 29 × 14 mm and the male tag measures 29 × 23 mm. Together they lock through the ear and stay attached through weather, dust, and daily animal movement.
These ISO 11784 11785 livestock tags work with any FDX-B-compatible reader, including handheld stick readers, panel readers, and fixed RFID systems. The read range is 50–70 cm, enough for chute-side scanning without restraining animals tightly.

Applications for Animal Farming
- Cattle identification: Link each cow to milk production records, health history, and breeding cycles
- Sheep and goat tracking: Manage flocks with individual IDs for wool, meat, and breeding programs
- Pig and swine management: Track vaccinations, weight gain, and litter data from farrowing to market
- Disease control: Isolate sick animals quickly by scanning their tag and pulling up health records
- Movement traceability: Record animal transfers between farms, markets, and slaughter facilities
- Automated farm systems: Connect tags to automated weighing, feeding, and milking equipment
How to Apply These Ear Tags
- Match the tag with the correct applicator for your tag model.
- Restrain the animal in a chute or headgate.
- Place the female tag on the inside of the ear and the male tag on the outside.
- Squeeze the applicator firmly to lock the two parts together.
- Scan the tag with your FDX-B reader and record the ID in your management system.

Frequently Asked Questions
Q: What are livestock ID tags?
A: Livestock ID tags are electronic ear tags that store a unique identification number on an RFID chip. They let farmers scan and identify animals automatically without reading printed numbers by hand.
Q: What is FDX-B protocol?
A: FDX-B (Full Duplex Extended) is a low-frequency RFID communication protocol defined under ISO 11784/11785. It operates at 134.2 kHz and provides stable, close-range identification for individual animals. FDX-B tags are widely used in official livestock identification programs worldwide.
Q: What frequency do these tags use?
A: These tags operate at 134.2 kHz, which is the standard low-frequency band for animal identification under ISO 11784/11785.
Q: Are these tags ISO 11784/11785 compliant?
A: Yes. These ISO 11784 11785 livestock tags follow the FDX-B protocol and are compatible with any reader that supports the same standard.
Q: How long do these tags last?
A: With TPU construction, IP68 sealing, and ≥ 270 N tensile strength, these tags are designed to last the lifetime of the animal under normal farm conditions.
Q: What animals can these tags be used on?
A: These tags work for cattle, sheep, goats, pigs, and other livestock. The 50–70 cm read range suits chute-side scanning for all common farm animals.
