What is a Sender ID?

A Sender ID is the name or number that appears as the sender when recipients receive your SMS or voice messages. Using a branded Sender ID helps recipients identify your business.
Sender IDs must be approved before they can be used. The approval process typically takes an hour or 24-48 hours.

Best Practices

Choose a Sender ID that clearly identifies your business. This builds trust with recipients.
Shorter Sender IDs are easier to read and remember. Aim for 6-8 characters.
Use the same Sender ID across all your campaigns for brand consistency.
Consider having different Sender IDs for different purposes:
  • MYCOMPANY for marketing
  • ALERTS for transactional messages
