A Sender ID appears on the mobile phone of the receiver and shows who the SMS is coming from.
When a person sends an SMS, the Sender ID is always the person’s phone number but when sending SMS over an API, there are variable options with either 15 digits or 11 characters in the range a-z, A-Z and 0-9.
Some countries have restrictions and not all type of sender ID's are allowed. If you are not complying with certain local regulations the sender ID may be overwritten by the operator or by CM to ensure delivery.
What is a Alphanumeric Sender ID: This allows you to set your brand or name as Sender ID. Alphanumeric Sender IDs may be up to 11 characters and can be a combination of numeric and alpha characters (0-9, a-z, A-Z). Some countries don't support alphanumeric senders. Check our Country specifics for more information about each country.

What is a Short Code?
Short codes are significantly shorter digit sequences than regular phone numbers, mostly 3 to 5 digits. Because such shorter numbers like 3333 are easier to remember, such short codes are often used by charities, television voting and other commercial purposes.

Long code stands for a regular MSISDN number virtualised and enabled for usage in Two-way messaging. You have a regular number that is linked to a system which you can use for interactions with the end users. These can be dedicated or shared.
