The BOLD Identification System (IDS) for COI accepts sequences from the 5' region of the mitochondrial Cytochrome c oxidase subunit I gene and returns a
species-level identification when one is
possible. Further validation with independent genetic markers will be desirable in
some forensic applications.

All Barcode Records on BOLD (1,161,439 Sequences)
Every COI barcode record on BOLD with a minimum sequence length of 500bp (warning: unvalidated library and includes records without species level identification). This includes many species represented by only one or two specimens as well as all species with interim taxonomy. This search only returns a list of the nearest matches and does not provide a probability of placement to a taxon.
Species Level Barcode Records (964,112 Sequences/92,715 Species/39,952 Interim Species)
Every COI barcode record with a species level identification and a minimum sequence length of 500bp. This includes many species represented by only one or two specimens as well as all species with interim taxonomy.
Public Record Barcode Database (232,881 Sequences/31,306 Species/9,198 Interim Species)
All published COI records from BOLD and GenBank with a minimum sequence length of 500bp. This library is a collection of records from the published projects section of BOLD.
Full Length Record Barcode Database (787,264 Sequences/83,489 Species/34,767 Interim Species)
Subset of the Species library with a minimum sequence length of 640bp and containing both public and private records. This library is intended for short sequence identification as it provides maximum overlap with short reads from the barcode region of COI.
