The challenge

Marketplaces need trust at scale without becoming identity repositories.

Platforms connecting buyers and sellers face fraud, underage access, and category-specific eligibility rules. Traditional verification often pushes marketplaces toward storing large volumes of identity data they do not need to retain.

Platform-wide fraud

Fake accounts and bot activity undermine trust between buyers, sellers, and the marketplace brand.

Category-specific rules

Different product categories need different proofs, but platforms often deploy one heavy verification flow for everyone.

Central identity risk

The more identity data a marketplace stores, the greater the platform's security and compliance burden.

Marketplace use cases

One proof layer across platform journeys.

Checkify Passes can be used wherever your customer or user needs to prove eligibility before continuing.

Seller onboarding

Confirm human presence or eligibility before allowing restricted category listings.

Buyer age gates

Require age proofs before purchase or access to restricted marketplace categories.

High-trust transactions

Add proof checks before escrow release, pickup, or premium service tiers.

Category-specific controls

Configure different Pass types for alcohol, tickets, digital goods, or local services.

Why marketplaces benefit

Build platform trust without hoarding user identity data.

Checkify gives marketplaces structured proof outcomes at key trust moments — onboarding, listing, checkout — without defaulting to central storage of full identity documents for every user.

That means clearer platform policies, reduced central data risk, and more respectful experiences for genuine buyers and sellers.

Benefits for marketplace operators

Configurable by category
Apply different proof types to different marketplace segments instead of one heavy flow.
Lower central data risk
Receive proof outcomes without storing unnecessary identity artefacts platform-wide.
Human and eligibility proofs
Combine human verification with age or category eligibility where required.
SDK and integration options
Embed proofs into custom marketplace flows via SDK or partner integrations.

A better trust model for genuine platform users.

Buyers and sellers expect marketplaces to be safe, but they do not expect to upload their entire identity for every category. Checkify helps platforms ask for the proof that matters.

Without Checkify

More forms, more data, more friction, and more sensitive information to protect.

With Checkify

A focused proof request that confirms what your business needs to know.

Seller onboarding

Verify sellers before restricted listings go live.

For marketplaces, Checkify can gate seller signup or category activation with human or eligibility proofs tailored to the listing type.

Configure Pass types per category so sellers only complete proofs relevant to what they intend to sell.

Example seller onboarding flow

1
Seller starts category signup
The marketplace requests the required proof before listing activation.
2
Seller approves Checkify Pass
They review and approve the proof request on their phone.
3
Listing eligibility confirmed
The platform receives the proof outcome and can enable the category.
Buyer journeys

Gate restricted purchases without platform-wide friction.

Marketplaces can add buyer-side proofs only for restricted categories — not every checkout across the platform.

Use targeted gates so genuine buyers on unrestricted categories experience no unnecessary verification steps.

Example buyer gate flow

1
Buyer reaches restricted checkout
The platform requests an age or eligibility proof for that category.
2
Buyer approves Checkify Pass
They complete the proof request on their phone.
3
Purchase continues
The marketplace receives the outcome and can complete the transaction.

Choose the proof request your business needs.
