The National Park Service (NPS) provides a certification program for Lewis and Clark sites along the Lewis and Clark National Historic Trail. This is an honorary designation allowing the site to be acknowledged as an integral part of the trail system and may allow the site to be listed in various interpretive materials. Certified sites are provided a wall plaque announcing the site as certified and an exterior sign displaying the national historic trail logo.

The Missouri Lewis and Clark Bicentennial Commission is in the process of securing certifications for interpretive sites across Missouri as part of its interpretive panel program. Certification of these sites will allow use of new "HISTORICAL MARKER" designations along Lewis and Clark National Historic Trail highway routes. Other Missouri sites may be signed with these markers if certified through the NPS certification process. Highway signing requests may be approved by the Missouri Department of Transportation if they include a copy of the Lewis and Clark National Historic Trail certification agreement.

A nonfederal entity must apply to the NPS and meet certain criteria to qualify for certification. To qualify, sites must be maintained in accordance with management practices consistent with NPS standards. Once certified, the Lewis and Clark National Historic Trail logo must be displayed at the site. At that time, application can be made to the Missouri Department of Transportation for highway route signing if so desired.
