A2P is automated/mass; P2P is manual and human. The distinction drives which rules apply, A2P traffic must be 10DLC-registered and is held to autodialer consent standards, while true one-to-one human texting is a different risk profile. The catch: a lot of 'P2P' tools blur the line, and courts look at substance, not labels.
Why campaigns care
If your sending is really A2P (software pushing to a list), you need registration and prior express consent, and calling it 'P2P' doesn't change that. The TCPA suits against campaigns have often turned on whether 'peer-to-peer' messages were actually sent with automated technology.
The safe posture
Don't build your compliance around squeezing into the P2P category. Get documented consent and register properly regardless of the sending method, then the P2P-vs-A2P distinction stops being a liability you're exposed to.
Frequently asked questions
What is the difference between P2P and A2P texting?
A2P is automated/mass software sending (regulated, must be registered); P2P is genuinely manual, one-to-one human texting. The rules differ, but courts judge by substance, not the label.
Does P2P texting avoid the TCPA?
Not reliably. If messages are actually sent with automated technology, they're treated as A2P regardless of 'P2P' framing. The safe path is documented consent and registration no matter the method.
