Yes, Missouri permits recording telephone calls and in-person conversations without consent under its “one-party consent” law (Mo. Rev. Stat. § 595.271), effective since 1994. However, federal law (18 U.S.C. § 2511) requires compliance with stricter jurisdictions if parties are outside Missouri. The Missouri Attorney General’s 2023 guidance warns businesses to verify call locations to avoid multi-party consent violations. Courts have upheld recordings as admissible evidence if at least one participant consents, but improper use may trigger wiretapping claims.
Key Regulations for Recording Phone Calls in Missouri
- One-party consent rule: Only one participant in the conversation must consent to recording; Missouri does not require notifying or obtaining permission from all parties (Mo. Rev. Stat. § 595.271).
- Federal dual-consent overlay: If any party to the call is in a two-party consent state (e.g., California, Illinois), federal law may require compliance with the stricter standard to avoid liability under 18 U.S.C. § 2511.
- Business-use limitations: Employers recording employee calls must disclose the practice in written policies; unauthorized interception for non-business purposes may violate the Missouri Wiretap Act and trigger civil penalties up to $10,000 per violation.
Recording without consent in Missouri remains lawful for personal use, but dissemination or use in legal proceedings requires adherence to evidentiary rules. The Missouri Public Service Commission’s 2026 draft guidelines on telecom compliance emphasize caller ID disclosures for automated recordings, reinforcing transparency obligations for businesses.
