Upwork Client
Project overview

The brief

The client required a seller ID verification system for their local buy-and-sell marketplace to ensure that every seller completes identity verification before publishing listings. The solution needed to integrate with the existing SMS verification process, allowing sellers to upload the front and back images of their government-issued ID for administrative review.

The goal was to strengthen marketplace security, increase user trust, and give administrators complete control over the seller verification process.

Our solution

What we built

We developed a custom WordPress ID verification plugin that integrates seamlessly into the marketplace and adds a secure verification step before sellers can create listings, designed to be simple for users while giving administrators an efficient review and approval workflow.

Key features
  • Government ID verification with front and back image uploads.
  • Integration with the existing SMS verification process.
  • Mandatory verification before sellers can publish listings.
  • Automatic account status updates while verification is in progress.

  • Admin approval system to verify or reject submitted documents.
  • Automatic account activation after successful verification.
