Colorado Ringless Voicemail Compliance

RVM (ringless voicemail drop) compliance rules in Colorado

⚠

Mini-TCPA State — C.R.S. § 6-1-901 et seq.

Colorado has enacted a state-level TCPA that goes beyond federal requirements. Federal compliance alone is not enough for Ringless Voicemail operations here.

Consent Requirements

Consent LevelWritten Consent Required

One-to-One Consent Required

Shared consent from lead generators is NOT valid. Consent must specifically name your company.

ATDS DefinitionBroader than federal
Checkbox ConsentValid
StatuteC.R.S. § 6-1-903

Ringless voicemail is not explicitly addressed in the statute, but the broad ATDS definition and the inclusion of prerecorded messages strongly suggest RVM requires prior express written consent. Conservative compliance approach: treat RVM the same as a prerecorded robocall.
