Find a species' bar code
To find the barcode for a particular species visit the BOLD DNA barcode finder

Identify specimen by genetic code
In order to identify a specimen based on its DNA code. You would have to select the sequences from the 5' region of the mitochondrial Cytochrome c oxidase subunit I gene and enter it in the BOLD DNA search engine

Search by Barcode Index Number (BIN)
The Barcode Index Number(BIN) System clusters sequences using well established algorithms to produce operational taxonomic units that closely correspond to species. BINs are unique in that clusters are indexed in a regimented way so genetically identical taxa encountered in different studies reside under shared identifiers . Clustering has been parameterized by using 'training data' from taxonomically diverse records collected by barcoding efforts to date. Training sets are based on established taxonomy to recognize those sequence clusters that are likely to correspond to biological species. Each novel cluster is assigned a globally unique identifier that is registered in the Barcode of Life Data System (BOLD).To find a species based on the genetic Barcode Index Number(BIN), search the BOLD BIN search engine
