Binance's dual-domain architecture — com vs us fundamentals
Binance launched binance.us in September 2019 under US regulatory pressure — a legally separate entity from binance.com (international), fully isolated in ownership, operations, and product, sharing only the brand and some UI. Differences: (1) Tokens: binance.com lists 500+, binance.us about 150; (2) Products: binance.com offers margin, futures, Earn, Launchpad; binance.us is spot-only; (3) Fees: binance.com 0.1%, binance.us 0.5% (5× higher); (4) Regulation: binance.com historically registered in offshore jurisdictions (Cayman, Malta, BVI over the years); binance.us holds FinCEN MSB + state-level MTL. Net result: US users are forced to binance.us with much weaker feature coverage. Many US crypto users instead pick Coinbase / Kraken over binance.us.
Blocked countries and regulatory shifts
binance.com blocked / restricted countries (evolving, as of early 2026): (1) Fully blocked — US (redirect to binance.us), Canada (full exit May 2023, some BC users excluded), Netherlands (April 2022 AFM-fine-then-exit); (2) Restricted access — UK (FCA restrictions on new customers + some products since 2021), Singapore (MAS compliance scopes to specific business lines), Japan (runs as separate Binance Japan entity, licensed August 2023); (3) Under regulation — France, Germany, Italy, Spain (most localizing under EU MiCA from June 2024); (4) Hard-blocked no VPN access — North Korea, Iran, Syria, Cuba. Mainland China: binance.com exited after the September 2017 ICO ban, but technically VPN-reachable; Binance doesn't explicitly ban Chinese users, but KYC doesn't accept mainland Chinese ID cards.
KYC tiers — from Basic to Verified Plus
Binance KYC has 3 tiers: (1) Unverified — small-amount spot only (typically 0.06 BTC daily withdrawal cap), most futures / Launchpad / fiat deposits closed; (2) Verified (Basic) — ID + selfie + address + occupation info, unlocks most features, ~8M USDT daily withdrawal; (3) Verified Plus — additional address proof (utility bill / bank statement within 6 months) + source-of-funds, daily withdrawal up to 200M USDT. Accepted ID: passport (universal), driver's license (select countries), national ID (by country). Mainland Chinese national ID has not been accepted since 2020 — the main bottleneck for Chinese users. Workarounds: (1) HK / SG / UAE national ID; (2) passport (most nationalities including non-Chinese); (3) proxy registration through family/friends (compliance gray zone). After KYC failure, the account can't deposit or trade, but existing assets can still be withdrawn.
VPN risks — this isn't streaming, it's financial compliance
Binance's terms of service explicitly prohibit: (1) users in restricted jurisdictions using the service; (2) using VPN to bypass geographic restrictions. Violations carry serious consequences: (1) account freeze — Binance can freeze indefinitely, assets locked; (2) KYC re-verification — triggered by 'address / IP mismatch'; (3) legal risk — in the US, using VPN to log into binance.com can be construed as sanctions violation (especially if tokens you traded have been OFAC-sanctioned). Real example: in 2023 Binance paid $4.3B in US SEC + CFTC penalties; one of the charges was 'knowingly allowing US users to bypass restrictions via VPN'. Binance's IP-KYC-address cross-validation tightened noticeably after. Don't underestimate this. US users' safest path is binance.us — reduced features but compliant. For binance.com features, consider Kraken Pro or OKX.
AF3 probe structure — 4-layer crypto exchange detection
AF3's Binance probes cover 4 layers: (1) Primary (binance.com HTML + not redirected to binance.us or regional sites); (2) API gateway (api.binance.com / fapi.binance.com — spot + futures core APIs); (3) Auth service (accounts.binance.com — login and 2FA); (4) CDN (bin.bnbstatic.com — static assets and candlestick charts). AF3 specifically watches redirect behavior — a US IP hitting binance.com gets 302'd to binance.us, which AF3 flags as 'regional redirect'. IP scoring: residential 30 / quality_vpn 25 / normal_vpn 20 / datacenter 15 — same 3-star fintech profile as Acorns. Datacenter IPs can still access, but the IP at KYC submission gets logged — long-term DC IP use effectively self-reports as 'possibly a bot'.
Practical advice — compliance first, stability second
Recommendations by user profile: (1) US users — use binance.us, accept reduced features; if you really need binance.com features, switch to Kraken / OKX. (2) Mainland Chinese users — KYC with passport (passes), and use Japan / Singapore / HK residential VPN (avoid US IPs, Binance risk control is stricter there); keep the same IP region long-term — switching US today, Japan tomorrow triggers risk control. (3) EU users — wait for each country's MiCA licensing and use the local Binance subsidiary. (4) Canada / UK users — accounts have been forced to migrate or close, consider Bitget / OKX / Kraken. Security tips: (1) enable 2FA (Google Authenticator, not SMS); (2) withdrawal allowlist; (3) move large holdings to cold wallets (Ledger / Trezor); (4) never use Binance on public Wi-Fi. AF3 only detects reachability — compliance and account security are on you.
