Is Colorado a One-Party Consent State? Call Recording Law (2026)

Is Colorado a one-party consent state?

Colorado is a one-party consent state: one person on the call can consent to it being recorded, so a business can record its own calls without asking the other caller under the state rule.

General information, not legal advice. Check the statute and talk to a lawyer about your situation.

The law

Rule: A one-party consent state
Statute: Colo. Rev. Stat. 18-9-303(1)(a) (statute text from Justia's copy of the state code)
Notes: Wiretapping is defined as a non-party recording a telephone or electronic communication without the consent of either the sender or a receiver.

For businesses using an AI receptionist

AI receptionists usually record and transcribe calls. Announcing at the start of the call that it's recorded, and that the caller is speaking with an AI assistant, is the common way businesses handle callers from states with stricter rules.

Calls with people in two-party states such as California, Florida, Illinois, Maryland can raise the question of which state's law applies, which is why many businesses announce recording on all calls.

Compare AI receptionists and check which ones announce recording and AI use.

Other Colorado rules for AI calls

Colorado Artificial Intelligence Act: disclosure of an AI system to consumers

AI disclosure, current status not confirmed

A business that deploys or makes available an AI system intended to interact with consumers must make sure each consumer who interacts with it is told they are interacting with an AI system. Disclosure is not required where it would be obvious to a reasonable person that they are interacting with an AI system. Nothing in the text limits the duty to text interfaces, so voice agents appear to be covered.
