Disclosed herein are system, method, and computer program product embodiments for delivering messages using enterprise numbers. In an embodiment, a messaging system may facilitate two-way communication between enterprises and end user devices through the user of shared enterprise numbers. Multiple content providers and/or service providers may use the shared enterprise numbers to reach a wide range of end user devices. The end user devices may be, for example, telephones capable of communicating via short message service (SMS). The messaging system may assign enterprise numbers based on sessions to avoid conflicts when receiving reply messages. In an embodiment, the messaging system may assign enterprise numbers so received replies may be returned to corresponding enterprises without relying on keywords to be present in the reply message.
