Quick answer: It depends on where you are and where the other person is. U.S. federal law lets someone who takes part in a call record it (18 U.S.C. § 2511(2)(d)), but that is only the federal layer. In France, recording words spoken in private without the speaker's consent can cost a year in prison and a €45,000 fine (article 226-1). The rule that works everywhere: tell the person, ask, and if there's no yes, the recording stays with you.
This article explains the texts; it is not legal advice for a specific situation.
There is no single "recording law"
Call recording is governed by the law of each country, and sometimes by several layers inside one country. Two people on the same call can be in different places, under different rules. So instead of asking "is it legal?", it helps to ask two narrower questions: can I record this call? and can I share the recording? The answers are often not the same.
Here is what two very different legal systems say.
The U.S. federal rule: one-party consent
The federal Wiretap Act makes it unlawful to intercept phone calls, with exceptions. The one that matters here is 18 U.S.C. § 2511(2)(d):
"It shall not be unlawful under this chapter for a person not acting under color of law to intercept a wire, oral, or electronic communication where such person is a party to the communication or where one of the parties to the communication has given prior consent to such interception unless such communication is intercepted for the purpose of committing any criminal or tortious act…"
This is what people mean by one-party consent: if you are on the call, your own consent can be enough under federal law. Two caveats, though:
- It is only the federal rule. It says nothing about what your state requires, or what the law is where the person you are calling lives. Check the rules that apply to both ends of the call.
- The purpose matters. The exception disappears if the recording is made to commit a criminal or tortious act, which is one more reason a prank should stay good-natured.
The French rule: consent of the speaker
PrankCall AI is run from France, and French law takes the opposite starting point.
Article 226-1 of the French Criminal Code punishes deliberately invading someone's private life by capturing, recording or transmitting, without the speaker's consent, words spoken in a private or confidential capacity: one year in prison and a €45,000 fine. Consent is presumed only when the recording was made "with the knowledge" of the people involved, who did not object while they were able to. That is why so many hotlines say "this call may be recorded".
Article 226-2 then covers what happens next: keeping such a recording, disclosing it to the public or to a third party, or using it in any way carries the same penalties. Playing the audio to a friend or posting it counts, not just pressing "record".
What PrankCall AI does with your calls
Better to know exactly what the tool does before you place a call. According to our privacy policy:
- every phone call is recorded, with both voices (the AI's and the person you called), and automatically transcribed;
- you can play back and download your own calls from your history;
- in-browser trials are not recorded (their script, chosen voice and transcript are kept);
- recordings, transcripts and scripts are kept for as long as your account exists and deleted with it;
- Bx Labs may access them for moderation and support, and every access is logged.
So the recording exists the moment the person picks up. What happens to it afterwards is up to you, and that is where the other person's consent comes in.
How to ask: three steps
1. Reveal the joke, then the recording
A prank ends with the reveal: "this was a joke from Sarah!" That is the moment to add, yourself or through whoever set it up, that the call was recorded. No secrets: it is what makes real consent possible.
2. Ask about each use separately
Consent is not all-or-nothing. Ask about:
- keeping it for yourself;
- playing it to the friends who were in on the joke;
- posting it on social media or in a video, which is a different matter entirely: strangers can now identify the person.
Plenty of people will happily laugh at the audio with friends and still say no to the internet. Both answers deserve respect.
3. Get the yes in writing
"Sure, send it to the group" by text message beats a yes on the phone that nobody remembers the next day. And no yes, no sharing: not in a group chat, not in a story, not "just to one friend".
When you shouldn't even ask
Some recordings should never leave your account, consent or not:
- a call that went wrong: the person got worried, angry, or hung up confused. Apologize instead;
- a call where the person shares personal details (address, health, relationships, work);
- a call to someone vulnerable (a child, an elderly or anxious person): that prank should not have happened.
These limits mirror those of the prank itself; see are prank calls illegal? for the full picture.
Calling a friend abroad
PrankCall AI calls 45 destinations, and recording rules differ from one country to the next. Rather than hunting for the most permissive rule, use the simplest one everywhere: tell them, ask before sharing. It holds up in every country, and between friends it mostly saves you an argument.
In short
- U.S. federal law allows one-party consent, but it is only one layer; French law requires the speaker's consent and also covers keeping and sharing the recording.
- Consent is only presumed when the person knew they were being recorded and could object.
- With PrankCall AI every call is recorded: reveal it along with the joke, ask what is OK, and share nothing without a yes.
