Before making contact
- Check the seller's verification, activity history and trade reviews together.
- Be cautious of unusually low prices and sellers insisting on external messaging or advance payment only.
- For vehicles, properties and businesses, independently verify ownership, registration documents and authority to act.
When meeting to trade
- Prefer daytime meetings in public places with CCTV, and bring someone for high-value trades.
- Recheck the item's condition and serial number, the contracting party and the bank account holder at the meeting.
- Never share OTPs, passwords or recovery codes. The Wooribayan team will never ask for them.
If something feels wrong
- Stop payments and the conversation, and use Report on the listing, profile or message screen.
- If you already paid, contact your bank or e-wallet provider immediately and preserve chat and payment evidence.
- Report threats, suspected scams or crimes to the relevant local authorities.
