One number for work. One for personal life. Another for added privacy. 2nd Line gives you a second phone number for business, online activity, and everyday communication. Choose a virtual line, make calls, send and receive supported texts, or request eligible SMS verification and OTP codes over Wi-Fi or mobile data—all from one account. A SECOND PHONE NUMBER FOR EVERY PART OF LIFE Keep your primary number private and organize communication with less clutter. • Add a virtual line for work, customers, or personal projects. • Keep professional calls and messages separate from personal conversations. • Use eligible temporary numbers for one-time verification requests. • Manage up to three independent renewable lines from one account. CALL OVER WI-FI OR MOBILE DATA Call supported destinations using the secondary line you select. • Receive incoming calls on eligible active lines. • See incoming, outgoing, missed, and answered calls in history. • View connected call duration and the line used for each call. • Switch between your work, personal, and private lines before calling. Call availability and credit use vary by destination, provider pricing, and connected duration. 2nd Line is not an emergency-calling service. MESSAGING MADE SIMPLE Keep conversations organized by line in a familiar inbox. • Send supported messages and receive replies with your selected number. • Keep work and personal conversations in separate threads. • Review delivery status and message-credit history. Incoming and outgoing SMS use message credits. Multi-segment messages may require additional credits. Messaging availability varies by number capability, country, carrier, and regulatory registration. SMS VERIFICATION AND OTP CODES Request temporary numbers for supported services and regions through a dedicated verification inbox. • Check service and country availability in real time. • Copy the temporary number and delivered code easily. • Follow the remaining time, cancellation status, and credit result in one place. Availability can change. Delivery and acceptance of SMS verification or OTP codes are controlled by third-party services and are not guaranteed. FLEXIBLE NUMBER OPTIONS Choose available US and Canadian virtual lines immediately. Additional countries and number types may require identity, address, or business information before activation. The app shows the applicable requirements and number capabilities before you submit a request. The number provider or relevant carrier makes the final approval decision. UP TO THREE LINES, ONE ACCOUNT • Subscribe to and manage up to three distinct phone numbers. • Choose the outgoing line before a call or message. • See which line received a call or message. • Manage each renewable number separately. Each additional renewable number requires its own active subscription. Inventory, capabilities, regulatory review, and activation times vary.
