If a platform permits external chat, consider a temporary link for practical questions about an item or collection. Keep payment and transaction protection within the marketplace itself.
Sometimes you need a quick conversation with someone you do not know well. Keeping your personal telephone number private can be a sensible boundary.
START A 1-ON-1 CHAT ↗If a platform permits external chat, consider a temporary link for practical questions about an item or collection. Keep payment and transaction protection within the marketplace itself.
People organising a handover or meeting can communicate without automatically exchanging personal numbers. Make sure both parties trust the invitation source.
A delivery handoff, small event or quick question does not always require a new lifelong contact in your messaging app.
Use the original platform to confirm the other person and check whether its rules allow moving the conversation elsewhere.
Choose 1-on-1 chat and share your private invite through a trusted channel. Do not post the room code publicly.
Never move payments, verification codes or account-recovery steps into a new chat to avoid marketplace protections. End the chat when it is no longer needed.
