KYC for Marketplaces 2026
Two-sided marketplaces typically run KYC on sellers (or contractors) rather than every buyer. The verification stack is lighter than regulated finance and the per-applicant cost typically falls in the $0.30-$1.60 range.
When marketplace KYC is required
- Payment-facilitator marketplaces. If your marketplace disburses funds to sellers via Stripe Connect, Adyen MarketPay, PayPal Commerce, etc., the payment partner's rules require seller KYC. See your payment partner's onboarding terms; Stripe Connect Standard accounts have different KYC obligations from Express or Custom.
- Marketplaces handling regulated goods. Age-restricted goods (alcohol, vaping, gambling-adjacent) trigger age + identity obligations under local consumer-protection regimes.
- Marketplaces facilitating contractor work. Many gig and freelance platforms verify worker identity to satisfy tax reporting (1099 in US, CIS in UK) and worker-status determination.
- Marketplaces with high-value transactions. Property, vehicles, luxury goods marketplaces typically run seller KYC for fraud and trust-and-safety reasons even when not legally required.
What marketplace KYC typically includes (and excludes)
- Document + selfie identity verification (most marketplaces)
- Address verification (less common, often only at payout)
- PEP, sanctions screening (less common; only if payment partner requires)
- Tax-ID lookup (US 1099, EU VAT, UK UTR) where tax reporting applies
- Usually not required: AML monitoring, enhanced due diligence, source-of-funds (those sit with the payment partner)

| Socure | $0.80 Document Verification | US-centric; $1,000/mo free credit covers ~1,250 DocV |

Worked example: 1,500 new sellers/month, identity only
Acme Marketplace Co. (illustrative example, not a real company) verifies 1,500 new sellers per month. Stripe Connect Express is the payment partner; no AML required at the marketplace tier.
For a US-only marketplace, Socure's free credit covers most of the volume and DocV-only is enough. For an international marketplace, Didit's flat $0.33 with 500 free is hard to beat. Stripe Identity is the right pick if you already run Stripe Connect and the marginal $2,000 is worth one-vendor simplicity for the platform team.
The Stripe Connect one-vendor case
Marketplaces that run Stripe Connect for payouts often default to Stripe Identity because the integration is built-in. The cost premium versus Didit or Socure (roughly 5x at low volume) buys you one-vendor procurement, billing, support and DPA. For platform teams without a dedicated compliance procurement function, that is sometimes the right trade.
