The wedge-billed woodcreeper is the only member of its genus. It has these 13 subspecies that are sorted into three groups and a species by the Clements taxonomy: "spirurus" group "cuneatus" group The groups differ vocally; that and plumage and genetic differences among the subspecies suggest that the wedge-billed woodcreeper is actually more than one species.

GBIF citizen-science records
It is estimated from how often the Wedge-billed Woodcreeper is recorded against all the birds logged in Cuyabeno Wildlife Reserve (24 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
