Even though the state deadline is November 1, The Georgia National fair requires the following:  
10.   IDENTIFICATION: All Steers, Commercial Heifers and Market Heifers must have a STATE ear tag number listed on the entry. The ear tag number in the animals ear must match ear tag number on entry form when the animal is weighed in (tattoo numbers are not accepted for ear tag number on entry form). Only one (1) tag per animal. Steer and Commercial Heifers will require STATE ear tags purchased through your Agriculture Education Teacher or County Agent, no other tags will be accepted. If a animal loses a tag, notify the GNFA Livestock office, no later than 7 days after tag is lost.   
11.   Tattoos are required on all cattle
Have a Blessed Day!
