LinkedIn Unlock Check

Server-side probes verify LinkedIn reachability. Microsoft's global professional social network (1.2B+ registered members in 200+ countries as of 2026-04 — the largest platform in AF3's matrix). Founded 2003-05-05 by Reid Hoffman + 4 co-founders in Mountain View, CA; NYSE IPO 2011-05-19 (LNKD); Microsoft acquired all-cash for $26.2B on 2016-12-08 (Microsoft's largest acquisition at the time). Product matrix: Free / Premium ($29.99/mo) / Sales Navigator ($99.99/mo) / Recruiter ($835/mo) / Marketing Solutions / LinkedIn Learning (20,000+ courses) — all share one account. **VPN strictness ★★☆☆☆ (2-star, lenient)** — LinkedIn itself does NOT actively block VPNs. AF3's unique dual-layer reverse list: **Layer 1 sovereign blocks** (BLOCKED_REGIONS 3 countries) 🇨🇳 China (fully exited 2023-05-09, InCareer shutdown) / 🇷🇺 Russia (Roskomnadzor order 2016-11-10, first Western social network blocked in Russia; reason: refused data localization) / 🇰🇿 Kazakhstan (blocked since 2021); **Layer 2 OFAC paid-only** (OFAC_LIMITED_REGIONS 4 regions) 🇨🇺 Cuba / 🇮🇷 Iran / 🇰🇵 DPRK / 🇸🇾 Syria — free profile browsing may work, but Premium/Sales Navigator/Marketing Solutions not sold due to US Treasury OFAC sanctions. Cross-country login triggers email/SMS verification (not a block — pick one stable VPN country). Essential for Chinese / Russian overseas job seekers. Deep integration with Microsoft accounts.
