A standard mobile phone number used for two-way messaging, OTPs, or conversational communication.
Why Long Code Matters
A long code is a regular 10-digit number, cheaper and faster to acquire than a short code, and it is what most conversational and OTP use cases actually need, since they do not require the extreme throughput a short code is built for.
How Long Code Works
Functionally, a long code is provisioned and bound the same way any SMPP sending number is: it can be set up for outbound-only sending or for full two-way messaging, depending on whether inbound routing is configured for it.
How SMPPCenter Uses This
Most SMPPCenter customers send from long codes unless their volume or use case specifically calls for a short code, since long codes are simpler to provision and support full two-way messaging out of the box.
