What is Alphanumeric Sender ID?

Alphanumeric Sender ID helps businesses turn every SMS into a branded communication opportunity. Instead of sending messages from random phone numbers, your brand name appears clearly as the sender—building instant trust, improving recognition, and driving higher engagement.

By using a custom sender ID made from letters and numbers (0–9, a–z, A–Z, _), businesses can deliver OTPs, alerts, and promotions with a professional and credible presence. Discover how Alphanumeric Sender ID strengthens brand visibility and boosts SMS marketing performance with MailBIT Asia Pacific’s official SMS solutions.
