Do You Need a New Ticket to Transfer Between Seoul Subway Lines?

Highlights
The short answer
No — transferring between Seoul subway lines does not require a separate ticket or passing through any turnstiles, as long as you stay inside the paid area and follow the signs marked "Transfer" to the connecting platform. This applies whether you're using a transportation card or a single-journey ticket, and it comes directly from the operator's own current rider guidance rather than a general assumption about how transfers work.

Seoul's subway lines are run by more than one operator, but that doesn't mean switching lines mid-journey means buying in again.
Do I need a new ticket to change lines?
Transferring to another subway line does not require passing through any turnstiles or buying a separate ticket — follow the "Transfer" signs to the connecting platform
How do I find the right platform?
Follow the signage inside the paid area rather than exiting the station — the "Transfer" and "Direction to Transfer" signs lead directly to the connecting line's platform without you needing to tap out and back in.

Does this apply to both transportation cards and paper tickets?
