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 and operated by NEUROLINKER AI LLC, a Wyoming-based company providing customer-communication services for the hospitality and car-rental industries: our lines handle reservation support and booking notifications for travelers. Messaging on NumLines is powered by registered, compliant US carrier connections (A2P 10DLC).
Text messages sent through NumLines are conversational customer care and booking notifications only. Customers opt in by providing their phone number when booking or by texting us first, and can opt out at any time by replying STOP. No mobile information is shared with third parties or affiliates for marketing or promotional purposes. See our Privacy Policy and SMS Terms.
