TikTok, like many platforms employing two-factor authentication or account verification processes, typically sends security codes via SMS messages. These messages often originate from shortcode numbers, which are abbreviated phone numbers used by businesses for text messaging. The specific shortcode employed may vary based on geographic region or mobile carrier.
The use of shortcodes offers several advantages. They are generally easier for users to remember and type compared to standard phone numbers. Furthermore, shortcodes often provide a dedicated channel for automated messaging, enhancing reliability and deliverability. Historically, shortcodes have been utilized to facilitate services like voting, charitable donations, and marketing campaigns, demonstrating their established role in mobile communication.
