Large VI Alpha Tags for Individual Identification Visible Implant Alphanumeric (VI Alpha) Tags are used to identify individual animals. They are implanted subcutaneously but remain externally visible for easy recovery. VI Alpha Tags are now available in two sizes: standard (1.2 mm x 2.7 mm), shown in yellow, and large (2 mm x 5 mm), shown in orange. The larger tags are easier to read than the standard tags, and are suitable for larger animals.
