Interstate Call Recording: Which State's Law Applies?

When a caller and your business are in different states, more than one state's recording law can apply, and courts have often applied the stricter one. If you are in a one-party state and record a call with someone in an all-party state such as California, Florida or Pennsylvania, that state's law may protect them. The practical answer is to get every party's consent on every recorded call.

This guide explains how the conflict arises, what courts have done with it, and how to set up a recording practice that does not depend on knowing where anyone is.

This is general information, not legal advice.

Why interstate calls are a problem

Federal law sets a floor. The Wiretap Act, 18 U.S.C. § 2511(2)(d), lets a person record a call they are part of, or that one party consented to, unless the recording is for a criminal or tortious purpose. But it does not prevent states from being stricter, and about a dozen are.

Rule	States (phone calls)
All-party consent or notice	California, Connecticut (civil), Florida, Illinois (private conversations), Maryland, Massachusetts, Montana (knowledge or warning), Nevada, New Hampshire, Pennsylvania, Washington
Conflicting or disputed	Delaware, Michigan
One-party	The remaining states, DC and federal law

Every state's law protects people within its borders. When a call connects a one-party state to an all-party state, both laws have a claim to apply. See the state-by-state table for each state's statute.

How courts have handled it

Kearney v. Salomon Smith Barney (California, 2006)

The leading case. A brokerage's Atlanta office recorded calls with California clients without telling them. Georgia is one-party; California is all-party. The California Supreme Court applied California law, reasoning that failing to apply it would substantially impair California's interest in protecting the privacy of its residents, while applying it would impair Georgia's interests less. The court applied California's rule to future conduct and declined to award damages for past recordings, because the company could reasonably have relied on Georgia law before the decision.

After Kearney, out-of-state companies have been on notice: recording Californians without consent exposes them to California's remedy of $5,000 per violation under Penal Code § 637.2. And California Penal Code § 632.7 requires all-party consent to record any call involving a cellphone or cordless phone, regardless of confidentiality.

A statute written for cross-border calls

Some states wrote interstate reach into their statutes. Washington's RCW 9.73.030(1)(a) covers private communications "between points within or without the state."

Florida's approach to who can sue

According to the Reporters Committee for Freedom of the Press (RCFP), Florida courts have allowed claims where the plaintiffs are Florida residents or the intercepted words were spoken in Florida (Cohen Brothers, LLC v. ME Corp., 2004). Florida's civil remedy, § 934.10, also refuses good-faith reliance on the federal one-party rule as a defense.

Federal courts

Federal courts hearing state-law claims apply the choice-of-law rules of the state where they sit, which usually means a similar "interest" analysis. Results vary, but the pattern is clear enough: the stricter state often wins when its resident was recorded.

Why you cannot just check the area code

Many businesses try to decide case by case. That rarely works:

• People keep their cellphone numbers when they move. A 312 number may belong to someone now living in Texas, or a 214 number to someone in California.
• People travel. A Florida resident on vacation in Georgia is still a Florida resident.
• VoIP numbers can be used from anywhere.
• Conference calls can include people in several states at once.

Unless you ask every caller where they are, you do not know which law applies. Asking is more awkward than a ten-second notice.

Choice-of-law in practice: a comparison

Your location	Caller's location	Safe approach
One-party state	One-party state	Federal and both states allow participant recording; notice still recommended
One-party state	All-party state	Get all-party consent
All-party state	One-party state	Get all-party consent (your own state requires it)
All-party state	All-party state	Get all-party consent; meet the stricter state's method if they differ
Anywhere	Unknown	Get all-party consent

Four of the five rows end in the same place. That is the argument for a single national policy.

Method details that differ by state

When states require consent, they do not all define it the same way. A single policy should meet the most specific requirements.

State	What the statute or courts accept
Washington	An announcement to all parties, in any reasonably effective manner, that is itself recorded
Connecticut	Written or recorded consent, a recorded verbal notice at the start, or a beep tone about every 15 seconds
Montana	Recording is allowed for "persons given warning"; either party may provide the warning
Massachusetts	The offense is secret recording; awareness by all parties defeats it
Pennsylvania	Prior consent; courts find consent where parties knew or should have known
California	All parties' consent; a notice at the start followed by continuing is the common method

A recorded announcement at the very start of each call, heard by everyone, satisfies the methods in all of these states.

A national recording policy

1. Announce at the start of every recorded call. Inbound and outbound, before any substantive conversation.
2. Capture the announcement in the recording. This matters for Washington and Connecticut and is good evidence everywhere.
3. Announce again when someone joins. Transfers and conference calls add new parties.
4. Honor objections. If a caller does not want to be recorded, stop recording or offer another channel.
5. Get written consent from employees. They are parties too.
6. Do not record calls your business is not part of. That is unlawful in every state without consent.
7. Treat AI transcription and note-taking as recording. They capture the same audio.
8. Set retention and access rules. Consent does not cover careless storage.

Wording for each step is in call recording disclosure scripts.

Common questions in practice

We only record inbound calls. Does this still apply? Yes. Inbound callers can be anywhere.

We are a small business that only serves locals. Locals travel and move, and their phones go with them. The notice costs nothing.

Can our privacy policy cover consent? A website policy is not something callers hear. States that focus on knowledge or announcement expect notice on the call itself.

What about calls with people outside the US? Other countries have their own rules, and some are stricter. Announcing recording is the safe default there too.

Recording across state lines with Callata

Callata uses one setting for your whole account. When recording is on, both sides hear "This call may be recorded." as the call connects, on inbound and outbound calls, so you do not have to guess where callers are. Recordings are transcribed and summarized with sentiment and action items on the contact's history. Callata's terms keep consent-law compliance with you; for states that require the announcement to be recorded, check a sample recording to confirm the notice is captured. It costs $99 a month for a team of up to five, plus $20 a month for each person beyond that. Sign up.
