## What broadband technology do Seattle homes use?

Fiber reaches 77.1% of Seattle's residential units, 7th of the 45 cities we track and above the 62.2% median. Cable is almost everywhere (97.7%), so a cable IP is the most common home connection type. Copper DSL remains at 25.4%. Gigabit service (1,000/100 Mbps) is available to 95.7% of units, 9th of 45. Access type matters for testing: fiber and cable homes usually get their own public IPv4 address, while fixed wireless users often share one.

*FCC National Broadband Map, December 31, 2025 data; any provider, residential units*

| Access type in Seattle | Residential units covered | Rank among the 45 cities |
| --- | --- | --- |
| Fiber to the home | 77.1% | 7th |
| Cable (DOCSIS) | 97.7% | 10th |
| Copper DSL | 25.4% | 33rd |
| Fixed wireless (licensed and unlicensed) | 97.1% | 15th |
| Any terrestrial service at 100/20 Mbps or more | 99.9% | 5th |
| Any terrestrial service at 1,000/100 Mbps or more | 95.7% | 9th |
| Fiber at 1,000/100 Mbps or more | 67.8% | 10th |

## How do I target a Seattle ISP in my proxy username?

Start from the city: `USERNAME-country-us-state-wa-city-seattle` asks for any home IP in Seattle. Then add the ASN of the provider you need:

- `USERNAME-country-us-state-wa-city-seattle-asn-7922`: Comcast in Seattle.
- `USERNAME-country-us-state-wa-city-seattle-asn-209`: CenturyLink in Seattle.
- `USERNAME-country-us-state-wa-city-seattle-asn-7018`: AT&T in Seattle.
- `USERNAME-country-us-zip-98103-asn-7922`: Comcast in ZIP 98103 (Fremont).
- `USERNAME-country-us-state-wa-city-seattle-asn-209-session-seattl1-ttl-20`: one CenturyLink IP kept for up to 20 minutes.

Use `gw.broadbandproxies.com`, port 7777 for HTTP and HTTPS or 7778 for SOCKS5. If a request finds no IP online, drop the ZIP first, then the city, and keep the ASN.

## Seattle: Comcast, Quantum Fiber and Astound

Comcast reports service to 95.5% of Seattle's residential units, Lumen (Quantum Fiber, now owned by AT&T) to 77.7%, and Astound's former Wave network (AS11404) to 42.6%. Google LLC, which runs Google Fiber and the Webpass building service, shows 6.2%. Gigabit-capable service reaches 95.7% of units. Washington State's My Health My Data Act protects consumer health data, a narrower law than a comprehensive privacy statute.

Local program: Seattle IT Digital Equity program, guided by the Internet for All Resolution 31956 (July 2020).

## Which WA rules matter for checks from Seattle?

Washington had no comprehensive consumer privacy law as of October 2026; the closest is the Washington My Health My Data Act (2023), which covers consumer health data. Prices shown to Seattle shoppers may add sales tax at checkout: the combined state and local rate is 10.55% since 2026-10-01, so compare pre-tax prices when you check retail pages from a Seattle IP. Seattle is on Pacific Time: schedule checks of time-limited offers and local ads in that zone. Whatever the city, our [acceptable use policy](https://broadbandproxies.com/acceptable-use/) applies; blocked targets: Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587.

## Seattle residential proxy pricing

City and ASN targeting cost nothing extra. Prepaid traffic never expires. See [all plans](https://broadbandproxies.com/pricing/).

| Plan | Quantity | Price | Price per unit |
| --- | --- | --- | --- |
| Test | 1 GB | $2.63 | $2.63/GB |
| Team | 10 GB | $5.94 | $0.59/GB |
| Business | 100 GB | $50 | $0.50/GB |

In every plan: Protocols: HTTP, HTTPS, SOCKS5 · Targeting: ASN (ISP), state, city and ZIP in the US; country elsewhere; city availability varies · Sessions: Rotating or sticky (up to 30 minutes) · Authentication: Username and password, or an IP allowlist (up to 10 IPs) · Traffic expiry: Never expires

Prices in US dollars, paid in BTC, USDT, USDC, ETH, SOL, LTC. Fund your balance (at least $25, or the price of the plan you want), then buy from it; Unused balance stays on your account and never expires. When a purchase costs less than the minimum top-up, the part added only to reach the minimum is refundable on request to support within 30 days of the payment, in USDT or USDC, as long as it has not been spent. The rest of the balance is not paid back, except where the law requires it. No identity documents are asked for.

## Seattle residential proxies by ISP: FAQ

### Which ISPs can I target in Seattle?

Any of the providers in the table, by ASN. The widest wired networks in Seattle on the FCC map are Comcast (`asn-7922`, 95.5%), CenturyLink (`asn-209`, 77.7%), AT&T (`asn-7018`, 66.4%). T-Mobile Home Internet and Verizon 5G Home also appear, mainly as 5G home internet.

### How much do Seattle residential proxies cost?

$2.63 for 1 GB, $5.94 for 10 GB and $50 for 100 GB, as of October 2026. City, ZIP and ASN targeting for Seattle cost nothing extra, and prepaid traffic never expires. Pay in crypto from a $25 top-up; no KYC.

### Is Seattle a fiber city?

Largely, yes. The FCC map shows fiber available to 77.1% of Seattle's residential units (December 31, 2025), 7th of our 45 cities, against 97.7% for cable. Fiber at 1,000/100 Mbps or more reaches 67.8%.

### Can I target a Seattle ZIP code?

Yes. ZIP targeting works in the United States on every plan: `USERNAME-country-us-zip-98103` asks for Fremont, and `zip-98107` for Ballard. You can add an ASN, but a ZIP-plus-ISP request matches fewer homes, so test it before scaling.
