KYC Verification

Complete your identity verification (KYC) through Sumsub to activate your CoinDuffle dealer account. Learn the requirements, what documents you need, and how long the process takes.

KYC Verification

Know Your Customer (KYC) verification is a mandatory step for all CoinDuffle dealers. This process verifies your identity to comply with federal and state regulations governing the sale of precious metals and collectibles, and to protect both buyers and sellers on the platform.

CoinDuffle partners with Sumsub, a leading identity verification provider, to handle KYC securely and efficiently.

Why KYC Is Required

Identity verification serves several important purposes:

  • Regulatory compliance — Dealers selling precious metals must comply with anti-money laundering (AML) regulations
  • Fraud prevention — Verified identities help prevent fraudulent sellers from operating on the platform
  • Buyer confidence — Buyers trust a marketplace where every dealer has been verified
  • Payment processing — Stripe Connect requires verified identities for payouts
  • Platform integrity — KYC helps maintain the quality and trustworthiness of the CoinDuffle marketplace

What You'll Need

Before starting the verification process, have the following ready:

Required Documents

  • A valid government-issued photo ID — one of the following:
    • Driver's license (front and back)
    • Passport
    • State-issued ID card
    • National ID card

Required Information

  • Your full legal name (must match your ID)
  • Date of birth
  • Residential address
  • Social Security Number (last 4 digits, or full SSN depending on verification level)

Technical Requirements

  • A smartphone or computer with a camera (for taking photos or a selfie)
  • A well-lit environment for clear photos
  • A stable internet connection

The Verification Process

Step 1: Start Verification

Navigate to Account → KYC Verification in your seller dashboard. Click Begin Verification to launch the Sumsub verification widget.

Step 2: Enter Personal Information

Fill in your legal name, date of birth, and address. This information must match what's on your government-issued ID exactly.

Step 3: Upload Your ID

Take a clear photo of your government-issued ID. If using a driver's license, you'll need both the front and back.

Tips for a clear ID photo:

  • Place the ID on a dark, flat surface
  • Ensure all four corners of the ID are visible
  • Avoid glare and shadows
  • Make sure all text is legible
  • Do not cover any part of the ID with your fingers

Step 4: Complete a Selfie Check

You may be asked to take a selfie or complete a brief liveness check. This confirms that you are the person shown on the ID.

Tips for the selfie:

  • Face the camera directly
  • Ensure your face is well-lit and clearly visible
  • Remove hats, sunglasses, or anything obscuring your face
  • Follow any on-screen instructions (e.g., turning your head)

Step 5: Submit and Wait

Once you've submitted your documents and selfie, Sumsub will review your information. You can close the verification window — you'll be notified by email when the review is complete.

Verification Timeline

Most verifications are completed within a few minutes through Sumsub's automated review system. If manual review is required, it typically completes within a few hours during business days.

Verification Statuses

After submitting, your verification will show one of these statuses:

  • Pending — Your documents are being reviewed
  • Approved — Verification is complete and your account is active
  • Needs Review — Additional manual review is required (no action needed from you)
  • Action Required — Additional information or documents are needed from you
  • Rejected — Your verification was not approved (see reasons below)

Common Issues and How to Resolve Them

"Document is blurry or unreadable"

Retake the photo in better lighting, ensuring the camera is focused and all text on the ID is sharp and legible.

"Name doesn't match"

Your legal name in CoinDuffle must match your ID exactly. If your ID has a different name than what you entered, update your profile information to match.

"ID is expired"

Expired IDs are not accepted. Use a current, valid government-issued ID.

"Selfie doesn't match ID"

Ensure you're taking the selfie in good lighting and following any on-screen instructions for the liveness check. Remove glasses if they're causing glare.

"Address verification needed"

In some cases, you may be asked to provide a utility bill, bank statement, or other document showing your name and address. This document must be dated within the last 3 months.

After Verification

Once your KYC is approved:

  • Your seller account is activated
  • You can list products and make them visible to buyers
  • You can proceed with Stripe Connect setup if you haven't already
  • Your storefront becomes publicly accessible

Privacy and Data Security

CoinDuffle takes your personal data seriously:

  • Sumsub processes and stores identity documents according to strict security standards (SOC 2, GDPR compliant)
  • CoinDuffle does not store copies of your identity documents — they are held securely by Sumsub
  • Your SSN is encrypted and used only for regulatory compliance purposes
  • You can request deletion of your verification data by contacting support (subject to legal retention requirements)

Frequently Asked Questions

Can I sell before KYC is complete?

No. Your store and product listings will not be visible to buyers until KYC verification is approved. You can create your store profile and add products while waiting, but they won't go live until verification is complete.

What if I'm verifying as a business?

The primary business owner or authorized representative must complete personal KYC. Business verification (including EIN and business documentation) is handled separately during the Stripe Connect onboarding process.

Do I need to reverify?

KYC verification is a one-time process. You will not need to reverify unless your information changes significantly (e.g., legal name change) or if required by updated regulations.

What if my verification is rejected?

You'll receive an email explaining the reason. Most rejections can be resolved by resubmitting with corrected or clearer documents. If you believe the rejection was in error, contact support@coinduffle.com.
