NLIS cattle tags

What do the letters and numbers on an NLIS tag mean?

NLIS Tags are externally marked with a 16 character NLIS Number.
For Example: NLIS number - ABCD2345XBG00001

• ABCD2345 – PIC (Property ID Code)
• X – NLIS Code to identify the manufacturer
• B – NLIS Code to indicate device type (B = Breeder and E = Post Breeder)
• G – BREEDPLAN Year Code to indicate year of manufacture. (eg. G is 2011, H is 2012, J is 2013, etc.) Note: Cannot have year codes 'o' or 'i'.
• 00001 – Unique Management Number. The producer can specify this number sequence; first character can be alpha or numeric, numbers cannot be repeated within a calendar year.

NLIS tags are internally coded at time of manufacture with a 15 digit, globally unique RFID Number (EID - electronic ID).
