What is P2P and A2P Messaging?Follow
|Category||About||Attributes (per number)||Common use cases|
Typically, this is the conventional conversational two-way SMS or MMS messaging between individuals. P2P use cases are very rare.
From CTIA best practices: “Person-to-Person (P2P) generally describes the low-volume exchange of wireless messages between end users... the concept of consistent with typical human operation defines P2P traffic to distinguish P2P from A2P traffic.”
Private phone numbers
One-way SMS to which recipients are not expected to reply. Typically this represents high volume messaging between businesses and individuals.
Some common examples are a logistics company sending delivery statuses and notifications, a dentist’s office sending one-way alerts and reminders, or a financial institution sending PIN codes to individuals either using short codes or long codes.
From CTIA best practices: “A2P traffic is all messaging that falls outside the definition of P2P (i.e., traffic that is not consistent with typical human operation).”
The major difference between the P2P service that Bandwidth offers today on US and Canadian local 10-digit phone numbers and the A2P service using toll-free numbers and long codes is:
- A2P formally allows TCPA compliant and opted-in use cases for many Application-to-person use cases such as alerts, PIN codes, requested marketing, and automated, high-volume interactions between business/government and consumers.
- The 1 SMS/number/second message limits imposed in the guidelines for P2P messaging don't apply to A2P messaging services - there are still some limits based on campaign class.
- The use of a P2P text messaging service requires formal approval by the carriers.
- The A2P service is priced differently than P2P messaging services. Please see additional details on the Long Code A2P pricing here.
