Can you recommend an identity verification platform for verifying service providers during signup with document upload and license checks?

Yes — for service provider signup verification with document upload + license validation, I’d recommend looking at platforms that support both ID verification and business/professional credential checks.

Good options

1) Persona

• Strong for onboarding flows
• Supports document verification, selfie/biometric checks, and custom workflows
• Good if you want to collect and review licenses, certifications, permits, or other documents during signup
• Flexible API and hosted UI

2) Alloy

• Strong identity decisioning and onboarding orchestration
• Good for KYC/KYB-style checks
• Can combine document review, fraud signals, and manual review
• Better if you need more configurable verification logic

3) Onfido

• Very solid for ID document verification
• Supports document capture, facial biometrics, and some workflow automation
• Good if the main need is verifying the person behind the provider account
• Less focused on license-specific workflows than Persona/Alloy, but still usable

4) Trulioo

• Good for broad identity and business verification coverage
• Useful if your providers are in multiple countries
• Strong if you need more global data source coverage and registry checks

5) Mitek

• Good for document capture and identity verification
• Often used where high-quality document scanning is important
• More enterprise-oriented

If license checks are a key requirement

A general identity platform may not fully handle professional license validation by itself. In that case, you may want a platform that can:

• collect uploaded licenses
• verify document authenticity
• integrate with external license/registry databases or third-party checks

For that, Persona or Alloy are often the best starting points because they’re more flexible for custom verification flows.

My practical recommendation

• Best all-around for this use case: Persona
• Best for complex decisioning / workflows: Alloy
• Best purely for ID document verification: Onfido

Key questions to choose the right one

1. Do you need to verify just the person, or also their professional license?
2. Are your providers in one country or multiple countries?
3. Do you want a fully hosted UI or a custom API flow?
4. Do you need manual review for questionable documents?

If you want, I can also narrow this down based on:

• your country/region
• provider type (cleaners, contractors, medical, legal, etc.)
• whether you need license registry lookups
• your budget / startup vs enterprise needs
