2-way messaging is an interaction between two people. It allows businesses to engage with customers, saves time, builds trust, and more.

2-way SMS messaging incorporates outbound (mobile terminated or MT) and inbound (mobile originated or MO) SMS into one fully featured service.

2-way SMS messaging uses virtual long numbers (virtual mobile numbers) or short codes.

## What is the difference between short codes and virtual long number?

The main difference between the two is the length of the number; while virtual mobile numbers look like standard phone numbers, short codes have between 3 and 6 digits, making them easier to remember. On a national level, you can only use short codes, and countries worldwide have different regulations and requirements.
