# Sender ID or 'From Address' 

## What is a Sender ID or 'From Address'

Sender IDs are the name or number that your recipients will see when a message reaches their mobile phones. This is known as the ‘From Address’ in your MXT account. SMSGlobal offers a variety of options to send your messages from.

SMSGlobal's Sender ID options include:

- Shared Numbers
- A Custom Word (Alphanumeric Sender ID)
- Verified Numbers (only supported for Australia)
- Virtual Numbers
- Dedicated Numbers

There are multiple variations of Sender IDs:

- **Alphanumeric/Custom Word:** Consists of up to 11 letters (a-z) and/or digits (0-9). Other characters may be used but may not be supported by all phones and operators.
- **Long Code:** Numeric Sender IDs should be in an international format (e.g. 447712312312). Numeric Sender IDs are limited to 16 digits.
- **Short Code:** Numeric Short Codes are typically 5 or 6 digits. However, this can vary by country.
