A2P and P2P messaging are broadly categorized on the type and volume of traffic that is being sent.
A2P (Application to Person): In this type of messaging, an application acts as the sender and large volume of messages are sent per second. Bulk messaging, broadcasting, A2P usage, alert systems are good analogues for this type of messaging.
P2P (Person to Person): In this type of messaging a person acts as the sender. This type of messaging allows one to send a small volume of messages, and the traffic profile should resemble typical human behaviour, i.e. it should be conversational (two-way) and at a frequency of no more than 1 message per second per number.
US and Canada
There are many regulations around P2P and A2P traffic in the US and Canada.
US and Canada long codes should only be used for Two-Way P2P messaging. Spam filters are implemented by most carriers and mobile operators in the US and Canada to identity A2P traffic originating from long codes, and such traffic is being filtered out more than ever.
A2P messages in US and Canada should be sent via short codes and Toll-Free numbers only. Plivo offers short codes as well as SMS enabled Toll Free numbers for enterprise communication. Contact us with your specific needs for more information.
