Short Code

A SMS Short Code is a 5 digit number XXXXX, provided by mobile network operators, on which data (SMS) can be sent by subscribers of the mobile operators.

Long Code

A Virtual Mobile Number (VMN, SMS Long Number or MSISDN) enables your business or organisation to receive inbound SMS text messages from any mobile user on any mobile network, worldwide. Also known as long numbers or long codes, virtual mobile numbers (VMNs) allow anyone who receives your message to reply using a standard mobile number. Unlike texting a keyword to a short code, which is charged at a premium rate, replying to a VMN costs the standard rate, and is as easy as hitting 'reply' on your handset. This virtual mobile number appears in the sender ID field on the handset, so the user knows they won't be stung with a hefty charge for replying.
