Here at GCX, we take the quality of incoming listings very seriously as this is part of our Customer Due Diligence Policy/KYC process (Know Your Customer) to ensure the health of GCX. If we see high-value listings or a high quantity of listings, we may reach out for additional information via email such as proof of purchase, or images of your gift cards.
Responding directly to any emails/requests sent from our Marketplace Health team about your listings or your account is the best way to speed up the verification process.
