#Can I buy K-pop tickets on Korean sites like Melon or Interpark with a foreign credit card?
Only on the global versions. The Korean-language sites (Melon Ticket, Interpark, Yes24, NOL) expect a Korean payment method, so a foreign card gets rejected at checkout. Use the English global sites instead (Interpark Global, Melon Global, NOL World), which take overseas cards. The tradeoff is the global site usually cannot mail tickets to you, so you collect them at the venue on show day.
Tip A Korean account does not get you around this. Even with one, the Korean site still wants a Korean card or KakaoPay.
#Do I need a Korean passport or ID to verify my account when buying tickets?
No. There is no Korean passport for foreigners, and you do not need a Korean ID to buy. What the Korean sites run is 본인인증 (real-name verification), and that is tied to a Korean phone number registered in your real name, not a passport. If your account name, phone number, and card all match, that is enough. Your passport only matters at the venue, where staff check that its name matches the booking when you pick the tickets up.
Tip Book under your exact passport name. A name mismatch at pickup is the thing that actually gets people turned away.
#Will a tourist SIM or eSIM work for Korean ticketing verification?
Usually not. Short-term tourist SIMs and most travel eSIMs are not registered to your name with a Korean carrier, so they cannot complete the 본인인증 phone check the Korean apps (Interpark, Ticketlink, Melon Korean) ask for. That is why those apps are so painful for visitors. The way around it is to buy on the global English sites, which do not need a Korean number, or to have someone in Korea with a registered number help you.
#Do I pick up a physical ticket, or is mobile entry enough?
For most big K-pop concerts you still collect a physical ticket at the venue box office on the day, and they match your booking name to your passport. Pickup lines build for hours before doors, so get there early, especially if you booked through a global site that holds the tickets for venue collection. A few shows are moving to mobile entry, so read the specific event notice, but plan for in-person pickup unless it clearly says otherwise.
#Should I stay at a hotel right next to the venue?
Usually not. Hotels right by a big venue jump in price for concert weekends and sell out first, and you are still stuck in the same post-show crowd anyway. Staying one or two subway stops away on the line you ride home is normally cheaper, easier to book, and barely adds to the trip back. That is the whole point of our per-concert guides: the cheaper nearby areas, plus the exact way home after the encore.
