NumLines is a shared workspace for teams that talk to customers over US phone numbers. Send and receive SMS and MMS, handle calls, and keep every conversation visible to your whole team — across multiple numbers, around the clock.
Request early accessManage ten or more US phone numbers side by side, each with its own label and color, without switching accounts or devices.
Admins and operators share the same conversations simultaneously. No more session kick-outs or one-device limits.
Text messages, photo attachments, and voice calls with your customers — including senders from international numbers.
Unread badges, real-time updates, and push notifications keep a 24/7 support team on top of every thread.
NumLines is built by NEUROLINKER AI LLC, a Wyoming-based software company focused on communication tools for distributed customer-service teams in the hospitality and car-rental industries. Messaging on NumLines is powered by registered, compliant US carrier connections (A2P 10DLC).
