30. What is the difference between long code & short code?
Long Code
Long numbers, as the name implies, are long telephone numbers which can be up to 16 digits in length but are usually the length of a standard telephone number. Long numbers are cheaper to use than short codes and allow you to receive replies from the recipients.
Short Code
A shortcode is a memorable number between 3 and 7 digits in length. They are ideal for marketing campaigns and promotions where you want people to remember your number. Short codes are country specific.
