KYC (Know Your Customer) Instructions

Updated over 2 weeks ago

This guide will help you complete the Know Your Customer (KYC) process quickly and avoid common mistakes. Once your KYC is complete, you’ll be able to access all features on the platform.

What is KYC, and why is it required?

KYC is a standard identity verification process required under international financial regulations. It helps protect against fraud and ensures compliance with global anti-money laundering laws.

KYC verification is triggered when your payouts in a single currency exceed 200 USD, 180 EUR, or the equivalent in another currency.

If your client company has enabled automatic verification for all contractors, you will be required to complete KYC immediately after registering on the platform.

While verification is pending, you can continue to complete tasks and receive payments, but fund withdrawals will be restricted until KYC is approved.

We use KYC to:

  • Confirm your identity and residential address

  • Enable secure payments

  • Ensure compliance with partner banks and legal standards

Your data is safe. We only share information with banks if required to verify a transaction.

Documents required for KYC

To complete KYC, you’ll need to upload two documents:

1. Identity Verification (choose one):

  • Passport

  • National Identity Card

  • Residence Permit

  • Driver’s License

2. Proof of Residential Address (choose one):

  • Utility bill

  • Bank statement showing your full address

  • Tax or government-issued document confirming your address

Address verification requirements

Your address document must:

  • Be issued within the last six months

  • Clearly show:

    • Your full name

    • Your complete residential address (must match the one in your profile)

    • The issue date

    • Signature or stamp (if applicable)

Tip: A bank statement with your full address is usually the fastest and most reliable option.

Document Format

If your document is physical, please upload a high-quality photo. Make sure the entire document fits within the frame.

If your document is electronic, we recommend uploading it in PDF format to ensure proper processing by the system.

Documents Not Accepted by 4dev.com

Please do not upload:

  • Screenshots of documents

  • Mobile phone bills

  • Medical bills

  • Insurance policies

  • Lease agreements (however, you can provide one to your bank and upload the resulting bank statement)

  • Documents with handwritten notes

  • Documents older than six months

  • Documents issued in another person’s name

Additional Guidelines

Your ID and address documents may be issued in different countries, as long as your residential address is current.By law, invoices issued through the platform must display your current residential address.

You cannot use the same document (e.g., passport) to verify both identity and address.

To avoid delays, ensure that all document details match the information in your profile.

KYC for Sole Proprietorship

Note: You must complete KYC as an individual. If you registered as a sole proprietor, your details will change to those of an individual after KYC verification.

After successful verification, you can update your profile details to those of your sole proprietorship (enter your name, address, and registration number). To proceed, please contact us via online chat and provide your sole proprietorship registration certificate or another document confirming your registration. We will update your profile on the platform to reflect your sole proprietorship details.

You cannot update your profile to that of your sole proprietorship without first completing verification as an individual.

Data Confidentiality

4dev.com uses SumSub, a trusted provider for secure, automated document verification.

Your personal data is encrypted and stored securely, and it is never shared with third parties except when required for payment processing.
