The widespread occurrence of sequence and (meta)data errors in public repositories calls for comprehensive improvements of curation protocols leading to robust research and downstream analyses. We collated and curated all available GenBank cytochrome-b sequences for amphibians, a benchmark marker in this globally declining vertebrate clade. The Amphibia\u2019s Curated Database of Cytochrome-b (ACDC) consists of 36,514 sequences representing 2,309 species from 398 genera (median\u2009=\u20092 with 50% interquartile ranges of 1\u20137 species\/genus). We updated the taxonomic identity of &gt;4,800 sequences (ca. 13%) and found 2,359 (6%) conflicting sequences with 84% of the errors originating from taxonomic misidentifications. The database (accessible at<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"doi\" xlink:href=\"10.6084\/m9.figshare.9944759\">https:\/\/doi.org\/10.6084\/m9.figshare.9944759<\/jats:ext-link>) also includes an<jats:italic>R<\/jats:italic>script to replicate our study for other loci and taxonomic groups.
