Phone call recording · Legal how-to guide
How to record a phone call legally
Recording a phone call legally requires two things: knowing the consent rules for your state, and a method that works on modern phones. Android 10 and later block most call-recording apps from capturing internal audio. A physical recorder placed next to the phone captures both sides without any software workaround — and works on any device.

Quick answer
How to record a phone call legally — 4 steps
Legal recording starts before you press record — consent comes first.
1. Check the consent law for your state
One-party consent states allow you to record without notifying the other party. All-party consent states (California, Florida, Washington, and others) require everyone on the call to agree. When calls cross state lines, follow the stricter state's law.
2. Inform the other party and get verbal agreement
Say at the start of the call: "I'd like to record this conversation for my records — is that okay?" A verbal yes is sufficient in most jurisdictions. End the call if consent is refused.
3. Use a recording method that captures both sides clearly
Software-based apps are blocked on Android 10+ and require iOS 18 for native support. A physical AI recorder placed next to the phone captures both sides without depending on internal audio access.
4. Store the recording with a note of the consent obtained
Label the file with the date, parties, and that consent was given. For legal or business use, a written record of consent adds an additional layer of documentation.
Methods
Four ways to record a phone call
Compared on whether the method captures both sides clearly, which devices and OS versions it works on, and whether transcription is included.
Third-party apps (ACR, Cube ACR)
Popular on Android — but Android 10+ blocks internal audio access, rendering most apps unable to capture the incoming caller's voice.
Speaker mode + Voice Memos
Put the call on speaker and record with Voice Memos or another app. Captures both sides but audio quality is poor.
iOS 18 native call recording
Built-in feature on iOS 18+ that automatically announces the recording to all parties — good for consent compliance.
Physical AI recorder (Plaud Note Pro)
Place the recorder next to the phone during the call. Smart dual-mode auto-detects phone-call mode; physical capture bypasses OS audio restrictions.
Based on common call recording scenarios and Plaud product data. Recording laws vary by state and country — always obtain consent as required by applicable law before recording.
Tips
What makes a legal phone call recording good
A legally sound phone call recording requires four things beyond the recording itself: both sides captured clearly, a method that works regardless of phone model or OS version, an accurate transcript for documentation, and secure storage.
