Sometimes a trader may ask for your ID. If you're trading for the first time with a trader they may ask you to identify yourself. This is because in certain countries traders are required by local laws to know who their customers are. Most traders explain in the terms of the trade if they require ID verification or not. If you don't wish to give the trader your ID, you can always cancel the trade and search for a trader with less strict requirements. Always send your ID to the seller via the trade chat, our trade chat messages are kept encrypted on our servers and are deleted after 180 days. All photographs sent to the trade chat are also marked with a watermark to prevent misuse of the images.
