No. Different barcodes work best for different biological kingdoms. For animals, we use a section of the genome called CO1.

DNA barcoding enables us to identify and monitor species, and assemblages of species. This can be used for discovering species

A DNA barcode reference library is a collection of verified barcodes for a large number of species in a group

The principle of DNA barcoding was first tested by Paul Hebert and colleagues at the university of Guelph in 2003.
