Two-Way Messaging and SMS Short Codes
If you're looking to do 2-way SMS you need a short code. Another name for short codes and long codes is two way numbers, because they allow people to reply to your SMS messages, this is known as 2-way messaging. But what is the difference between a short code and a long code?
The answer lies in its name. A short code is a memorable number between 3 and 7 digits in length, which your customers, suppliers or employees can use to reply to your messages. They are ideal for marketing campaigns and promotions when you want people to easily remember your number or if you want to encourage conversations between you and your audience. Short codes are country specific and can't be used if you want to receive replies from international destinations.
There are two types of short codes - standard short codes and premium short codes. Standard short codes work across all major mobile operators. Mobile users receiving or sending messages to standard short codes are not charged any additional fees.
Premium short codes on the other hand, are used by businesses to generate revenue when they hold promotions or competitions. Usually the person receiving or responding to a message will be charged extra on their phone bill.
