Internet in Seattle

Seattle is one of the more competitive broadband markets in the country, and fiber-to-the-home is the dividing line between merely fast and genuinely future-proof. The city is served by a crowded field that includes Ziply Fiber, the cable incumbent Xfinity, and AT&T Fiber, alongside Quantum Fiber, which has built out fiber across a large share of Seattle neighborhoods but not all of them. That density matters because Seattle is a remote-work and tech hub where symmetrical upload speeds (just as fast up as down) are a real differentiator for video calls, large file transfers, cloud backups, and game streaming, things cable connections historically throttle on the upload side. Layer in the Pacific Northwest's hilly, tree-heavy terrain and a patchwork of older and newer housing stock from Ballard to Beacon Hill, and you get a city where the fiber map genuinely varies street to street rather than ZIP code to ZIP code.

Is Quantum Fiber available in Seattle?

Quantum Fiber serves a meaningful portion of Seattle, but availability is strictly address-specific, two homes on the same block can get different answers depending on where fiber has actually been built. Because of that, the only reliable way to know what you can get is to enter your exact street address on quantumfiber.com and let the coverage tool confirm which plans and speeds are live at your home. Don't assume your neighborhood is covered just because a nearby home is; check the precise address before you make any decisions.

• Quantum Fiber is fiber-to-the-home (now branded Quantum Fiber from AT&T after AT&T acquired the consumer fiber business in February 2026); the network and plans in Seattle are unchanged, only ownership and branding shifted.
• Seattle plans run across the standard tiers (roughly 200 Mbps, 500 Mbps, 1 Gig, 2 Gig, 3 Gig, and up to 8 Gig in select areas), with the 500 Mbps and 1 Gig plans delivering symmetrical upload and download speeds, ideal for the city's remote workers and creators.
• No annual contract, no early-termination fee, and no data caps; 360 WiFi (a Wi-Fi 7 gateway, plus mesh pods where needed) is included, and self-install is available in many Seattle markets in about 10 to 15 minutes.
• Through the Aklamio Refer-and-Earn program, you and each friend you refer can earn up to $100 each in cash via PayPal or bank deposit, not a gift card or bill credit, after they stay active for 60 consecutive days; note the site owner may also earn a referral reward.

How to sign up in Seattle

Open the referral link, enter your Seattle address to confirm the fiber is live on your street, choose your speed, and pick self-install or a technician visit. Your referral reward is tagged to the order automatically — there’s nothing to claim separately.

Fiber availability is street-by-street and expanding, so an address a block away may differ from yours — always check your specific address on quantumfiber.com. Last reviewed June 1, 2026.
