Statutory Requirements.
1) All sheep born on or after 31st December 2009 must be identified according to the
current rules. Older sheep are covered by earlier legislation.
2) All sheep kept beyond 12 months of age must be identified with one electronic
tag/bolus and one visual tag.
3) Any sheep intended for slaughter before 12 months of age can be tagged with a single
slaughter tag which can be electronic or visual, although they may also be identified as
per point 2).
However, in Scotland, any slaughter tag MUST be electronic.4) In England and Wales, electronic tags MUST be yellow and visual tags must not be
yellow.
Scotland is different in that although SEERAD recommend yellow as the colour
for EID tags, it is not compulsory and is also permitted as a colour for matching visual
tags.5) Red is the colour reserved for replacement tags where the animal IS NOT on its holding
of birth. Where the electronic identification is a ruminal bolus, rather than a tag, the
visual tag MUST be black. Red and black are reserved for these purposes only.
6) If an animal is tagged with a slaughter only tag, and is still on its holding of birth, it
may be upgraded to full EID (double tagged) by removing the slaughter tag and inserting
one electronic tag and a marching visual tag.
7) Rules covering replacement tags are the same for animals born since the introduction
of EID and older animals. Where the sheep is on its birth holding, a lost tag can either
be replaced by a replacement identical to the lost tag OR the remaining tag can also be
removed and a new pair of tags applied. Where the latter option is used, the old and new
tag numbers must be cross referenced in your flock record book.

Replacement tags for animals not on their holding of birth are as per 7) except that
the tags MUST be red.
9) Where a sheep has lost a slaughter tag, it can be replaced with another. Where the
animal is not on its birth holding, the new slaughter tag must be red.
eg:
Full EID - UK number & Individual Number Double tags for animals kept for more
than 12 months.
Slaughter only - UK flock number only. Can be electronic or electronic. Must be yellow
if electronic.
