27/05/2019: New international standard for cattle EID

The International Organization for Standardization (ISO) is in the process of devising a new international standard for animal identification, to replace the long-standing standard known as ISO11784 that currently dictates how electronic identifiers, for use on animals, are encoded using LF technology.

Compliance with ISO11784 is the reason that bovine EID using LF technology will require renumbering of cattle across the UK, including in Scotland. Global recognition that ISO11784 is somewhat out-dated has prompted moves to replace it with a more flexible approach that also recognises recent technological advances (e.g. it will apply to UHF as well LF). As-and-when the new standard is introduced, it would allow LF-based bovine EID to be adopted across the UK without requiring changes to the cattle numbering system, thereby avoiding some costs and disruption.

The attached one-page paper provides some more details on this.
