One-Party Consent States vs. Two-Party States: The Map for Callers

Most of the United States is one-party consent territory: under the federal wiretap statute and most state laws, you may record a phone call you are a party to without telling the other side. One-party consent states are the default; twelve states — plus Connecticut, through its civil statute — require all-party consent or notice for phone calls. On interstate calls, courts have applied the stricter state’s law. The working rule for callers is simple: announce the recording at the start of every recorded call. Here is the verified map, as of July 2026.

This page is education, not legal advice. A dialer is a tool — compliance depends on how you use it. Recording laws shift, courts split, and several statutes below carry felony penalties. Before you turn call recording on, have an attorney review your disclosure practices for the states you call into.

The Federal Baseline: One-Party Consent

The federal wiretap statute, 18 U.S.C. § 2511(2)(d), makes it lawful for a private person to record a wire, oral, or electronic communication where that person is a party to it, or where one party has given prior consent — unless the recording is for a criminal or tortious purpose. Federally, you may record your own calls.

Federal law is the floor, not the ceiling: states layer their own phone call recording laws on top, and a minority require consent — or at least knowledge — from everyone on the call. Those states set your policy.

Two-Party Consent States: The Verified All-Party List

“Two-party consent” is the common name; the accurate term is all-party — everyone on the call. As of July 2026, these states require all-party consent or notice for recording phone calls, verified against the Reporters Committee for Freedom of the Press (RCFP) state guides:

These are criminal statutes: Maryland’s felony carries up to 5 years and a $10,000 fine, Pennsylvania’s up to 7 years plus civil damages, and Florida treats most offenses as felonies.

Footnotes on the starred states

• Connecticut’s criminal law is one-party, but a separate civil statute awards damages, costs, and attorney’s fees for recording a call without written consent, verbal consent on the recording, or a recorded warning at the start. For a business, that is a notice-required state.
• Delaware has a one-party wiretap law and an older all-party privacy law. A federal court has read the privacy law to allow participant recording, but RCFP recommends the more restrictive standard.
• Michigan‘s statute reads all-party, but a 1982 appellate case, Sullivan v. Gray, held a participant does not need the others’ consent — reaffirmed by a federal court in 2021. The state supreme court has never resolved it; treat it as all-party.
• Nevada’s statute looks narrow, but its supreme court reads it as all-party for phone calls — extended to cellphones and texts in 2015 — while in-person conversations remain one-party.

One-Party Consent States: Everyone Else, Including Two That Lists Get Wrong

Every state not in the table above — plus D.C. — follows one-party consent for phone calls under its own statute and/or the federal baseline. Two deserve a correction, because vendor blogs routinely misfile them:

• Oregon is one-party for phone calls. ORS 165.540(1)(a) makes telephone and electronic communications one-party. Oregon’s separate in-person rule — all participants must be specifically informed before an oral conversation is recorded — was upheld 10–2 by the Ninth Circuit en banc in January 2025, reversing the 2023 panel decision. Neither rule makes Oregon two-party for phone calls.
• Vermont has no recording statute at all. No state wiretapping or eavesdropping law addresses phone recording there; the federal one-party baseline governs.

Three more need homework before you rely on a one-word label: RCFP’s introduction files Missouri as mixed depending on conversation type, and notes Hawaii and Maine impose consent rules in particularly private places. If those states matter to your calling, verify their current state guides directly.

Interstate Calls: Assume the Stricter State’s Law

Courts have split on whose law governs a recorded call that crosses state lines, and litigation can arise in either jurisdiction — so RCFP’s guidance is to err on the side of caution and assume the stricter state’s law applies.

The leading case is Kearney v. Salomon Smith Barney (Cal. 2006). A brokerage’s Georgia office — where one-party recording was lawful — recorded calls with clients in California. The California Supreme Court applied California’s all-party statute anyway and enjoined the practice. Multi-state legal charts for businesses reach the same conclusion: the caller in a one-party state is subject to the stricter law and needs everyone’s consent.

For a team dialing into multiple states, the consequence is blunt: your recording policy must satisfy the strictest state you call into, not the state you sit in.

The Practical Answer: Announce the Recording on Every Call

The Kearney court itself pointed at the fix: a business that adequately advises all parties, at the outset, of its intent to record would not violate California’s statute. Washington deems a reasonably effective recorded announcement to be consent. Connecticut’s civil statute is satisfied by a recorded warning. Massachusetts, New Hampshire, and Pennsylvania recognize consent implied from knowledge. One habit covers the strictest states on the list.

Recognized notification methods are an automated pre-call announcement, a verbal disclosure at call start, periodic beep tones, and written disclosures in customer agreements. Two practical notes:

1. Use a spoken or automated announcement, not beep tones alone. Whether a periodic beep satisfies California’s all-party rule remains uncertain — a first-line verbal or automated disclosure is the defensible version.
2. Give notice on every call rather than leaning on written consent, and keep records of when recording began and how recordings are stored.

In Enzo, call recording is optional — off unless you turn it on — and if you do, the consent work above belongs in the first line of your script.

The map is less complicated than the 50-row tables make it look: one-party consent states are the default, a dozen-plus require all-party consent or notice for phone calls, and interstate calls default to the stricter rule. Build the announcement into the opening of every recorded call and most of the map stops mattering.
