Available in hundreds of thousands of locations across multiple U.S. states and rapidly expanding, Quantum Fiber is positioning itself as a future‑ready internet option for households, remote workers, creators, and growing businesses that depend on strong, always‑on connectivity.
Quantum Fiber availability is expanding quickly, but service is still limited to specific cities and neighborhoods, so checking your exact address is the best way to see if you can get connected today. Quantum Fiber currently offers residential and business fiber internet to hundreds of thousands of locations across roughly 16–17 U.S. states, with especially strong coverage in markets like Phoenix, Denver, Las Vegas, Minneapolis, Orlando, Salt Lake City, Seattle, and several other fast‑growing metro areas. Coverage is concentrated in parts of the West, Midwest, and Florida, and reaches an estimated 2% of the U.S. population, making it one of the larger pure fiber networks and a serious alternative to cable where it is available. Because fiber expansion happens city by city and even street by street, Quantum Fiber provides an online “Check Availability” tool where you can enter your address to see live availability, view current plans, or sign up for notifications if your location is on the upcoming build‑out list. This address‑level lookup helps ensure you get accurate information about whether Quantum Fiber’s ultra‑fast fiber internet is already in your building or coming soon to your area.
