- 2Vendor-claimed 350M+ residential IPs across 200+ countries and ~12,486 cities; depth disputed by independent reviewers
- 3Targeting at country, city, ZIP, ISP and ASN level; HTTP/HTTPS/SOCKS5 with sticky and rotating sessions

The verdict
Benchmark data and published specifications — here's where PIA S5 Proxy lands.
- Flagship pay-per-IP SOCKS5 model lets you buy distinct IPs rather than GB, ideal for multi-accounting and antidetect workflows
- Low entry pricing, listed from about $36 for 150 IPs and dropping to roughly $0.05/IP at enterprise volume
- Purchased IP balances are advertised as never expiring, friendly to intermittent buyers
- Granular targeting: country, city, postcode/ZIP, ISP and ASN level per the relaunched site
- Broad advertised coverage of 200+ countries and ~12,486 cities with HTTP, HTTPS and SOCKS5 support
- API access on all plans plus a desktop proxy manager and antidetect-browser integration
- No-KYC, no monthly fee on the pay-per-IP product
- Brand was taken offline in early 2026 and is mid-rebuild; database and platform restoration were still in progress per the site
- Network has been publicly linked to the IPIDEA ecosystem named in Google's January 2026 botnet-proxy crackdown, raising sourcing and consent questions
- Crypto-only checkout (BTC, ETH, USDT, XMR, LTC) with no card or PayPal, no chargeback protection
- Advertised 350M+ pool appears inflated at granular city/ISP targeting per independent reviewers
- No free trial and no clearly published money-back guarantee
- Proxy sourcing and consent model not transparently documented; manager app resembles the discontinued 911 S5 tool

What we think after testing PIA S5 Proxy
Editorial review by Maya Cortez · last updated Jul 16, 2026
PIA S5 Proxy is a residential proxy provider best known for its SOCKS5 pay-per-IP product, marketed for years as one of the largest commercial residential proxy networks. The brand has had a turbulent history: the original service went offline in early 2026 after Google's January 2026 disruption of botnet-linked proxy infrastructure named the wider IPIDEA network that PIA S5 has been publicly associated with. The site now operating at pias5proxy.com (also reachable as pia5proxy.com) presents itself as the direct continuation of PIA S5 Proxy, stating it runs on the same residential network and is operated by part of the original team. Anyone evaluating the provider today should read this review in that context: the brand is mid-rebuild, and its database recovery and platform restoration were, per the site, still in progress as of 2026.
On published specifications, the headline numbers are large. The site advertises 'over 350 million fresh residential IPs' spanning 200+ countries and regions, with city-level coverage cited around 12,486 cities. It is important to be clear that this 350M figure is a vendor-published claim, and independent reviewers (notably independent testers) have flagged it as exaggerated, warning that once you narrow targeting down to a specific city and ISP you should not expect hundreds of distinct IPs, with countries like China especially thin. Treat the pool size as marketing ceiling, not guaranteed depth.
The product lineup, per the site, is built around three lines that all draw from the same residential pool: PIA SOCKS5 (pay-per-IP), PIA Residential (pay-per-GB traffic), and PIA Static ISP proxies (monthly). All support HTTP, HTTPS and SOCKS5 protocols, and targeting is offered at country, city, postcode/ZIP and ISP level, with ASN-level targeting also listed on the relaunched site. The SOCKS5 pay-per-IP model is the flagship and is what differentiates PIA from GB-metered competitors: you buy a quantity of IPs rather than a bucket of bandwidth, which suits account-management and antidetect-browser workflows that need many distinct, persistent identities rather than high-volume scraping throughput.
Pricing on the relaunched site starts low. The entry SOCKS5 tier is listed at $36 for 150 IPs (roughly $0.24 per IP), scaling down to about $0.10/IP on a ~$156 tier, $0.09/IP on a ~$300 tier, and as low as ~$0.05/IP at the $900 enterprise level, with bonus IPs bundled on higher tiers. Residential traffic is quoted around $0.35/GB and static ISP proxies are billed monthly per IP. A notable selling point is that purchased IP balances are advertised as never expiring, which is unusual and friendly to intermittent buyers. The site states there is no KYC and no monthly fee on the pay-per-IP product.
On payments, the relaunched platform is crypto-only at checkout, accepting Bitcoin, Ethereum, USDT, Monero and Litecoin per the site. That is a meaningful limitation versus the older PIA storefront, which historically also took cards and PayPal: buyers who need a card receipt or chargeback protection are out of luck here. Crypto-only checkout, combined with the no-KYC stance, is convenient for privacy-minded users but is also a trust signal worth weighing given the sourcing concerns around the network.
Feature-wise, the service provides API access across plans, IP-whitelist and username/password authentication, sticky sessions (advertised up to roughly 30 minutes) and per-request rotation, sub-accounts on higher tiers, and a desktop proxy-manager application. Reviewers have repeatedly noted that this proxy manager closely resembles the interface of the discontinued 911 S5 tool, which is part of why the brand draws scrutiny. The provider integrates cleanly with antidetect browsers and multi-accounting tools, which is its core use case.
Who is it for? On specs and price, PIA S5 fits buyers who need a large quantity of cheap, country/city-targeted residential SOCKS5 IPs for social media account management, ad verification, ecommerce monitoring, market research and antidetect-browser automation, and who are comfortable paying in crypto. It is less suited to high-throughput data scraping where GB-metered residential or a dedicated scraping API from a more transparent vendor would be a better fit.
The caveats are significant and should not be glossed over. The brand is freshly relaunched after an enforcement-driven outage, the network has been publicly tied to IPIDEA in reporting that raised consent and sourcing questions, the proxy sourcing and consent model is not transparently documented, the advertised pool depth appears inflated at granular targeting levels, and checkout is crypto-only with no free trial and no clearly published money-back guarantee. No independently verified performance benchmarks (success rate, response time, uptime) are published by us here; the only uptime-style figure is the vendor's own '99.9% IP availability' claim, which is unverified.
