You finally find the Seongsu pop-up you flew across the world for, you tap "Reserve," and Korea slams a door in your face: "Verify your Korean phone number." You don't have one. You can't get one as a tourist. Most travel blogs stop here and shrug. This guide doesn't — here's exactly how to book anyway, ranked by what actually works.
· Why Naver/Kakao/Tabling block you (the real-name rule)
· Option 1: CatchTable Global — the tourist workaround
· Option 2: a prepaid Korean number, if you really need one
· Option 3: on-site & concierge tricks when booking fails
1. Why you're blocked — the real-name rule
Korea registers every mobile line to a verified identity. For a foreigner, the proof is a physical Alien Registration Card (ARC) plus a local carrier contract — things tourists simply don't have. Because Naver, Kakao, and Tabling all hang their reservations on that verification, a normal visitor can't pass it, no matter how good your data connection is.
2. Option 1 — CatchTable Global (start here)
For most tourists this is the answer. CatchTable Global is built specifically to skip Korea's identity check.
It covers a huge range of restaurants and many pop-up cafés and venues. If your target is bookable anywhere, it's usually here first.
3. Option 2 — get a prepaid Korean number
Some pop-ups (and Naver Booking specifically) only work with a Korean 010 number. If you're going to need it more than once — bookings, deliveries, certain apps — buy a prepaid SIM that includes a Korean number, not a data-only eSIM.
| What | Detail |
|---|---|
| Where | Airport kiosks, convenience stores, MVNO providers (e.g. KT M Mobile, U+ MVNOs, EG SIM) |
| What you need | Just your passport (no ARC required for prepaid tourist plans) |
| Cost (typical) | About ₩30,000–₩60,000/month for unlimited-data plans with a number |
With a Korean 010 number you can pass Naver verification and book directly — useful if your trip leans heavily on local apps.

4. Option 3 — when booking still fails
Plenty of Seongsu pop-ups don't take online reservations at all, or sell out instantly. Have these ready:
FAQ
Yes — use CatchTable Global, which lets you sign up with a Google or Apple ID and pay the deposit with a foreign card.
Usually no. Standard data eSIMs are data-only. For a Korean 010 number you need a prepaid SIM plan that explicitly includes one.
Naver booking requires Korean real-name verification tied to a local number and ARC, which tourists don't have. A prepaid Korean number can get you past it.
Show up before opening, use the on-site foreigner kiosk, or ask your hotel concierge to call for you.
