An alphanumeric sender ID puts your brand name (3 to 11 characters) at the top of login codes, shipping updates, and appointment reminders so recipients recognize the sender immediately. Because alphanumeric senders cannot receive replies and are blocked in number-only markets like the United States and Canada, pair your registered brand name with a verified toll-free number, 10DLC long code, or short code in countries that require a dialable number or two-way conversations.
