Thirteen subspecies of Certhia americana are currently recognized:
- C. a. alascensis: South-central Alaska; winters to Arizona and New Mexico
- C. a. occidentalis: Coastal south-eastern Alaska to central California (south to Marin County)
- C. a. phillipsi: Resident in outer Coast Ranges of central California (San Mateo County s to San Luis Obispo County)
- C. a. stewarti: Haida Gwaii (British Columbia)
- C. a. montana: British Columbia to Cascades, the Dakotas, southern Arizona and western Texas
- C. a. zelotes: Southern Oregon through Cascades and inner Coast ranges to southern California
- C. a. americana: Northern Saskatchewan to Newfoundland and north-eastern US; winters to Mexico
- C. a. idahoensis: Northern Idaho and north-western Montana to central Alberta; winters to Arizona
- C. a. nigrescens: Great Smoky Mountains of Tennessee and North Carolina
- C. a. albescens: Mountains of south-eastern Arizona, south-western New Mexico and north-western Mexico
- C. a. alticola: Mountains of southern Mexico
