If your Korean home uses city gas and you are moving out, open your supplier’s move-out reservation page before moving day. The current Korean forms of three providers all treat the task as a booking tied to a person, an address, and a visit date. One of them explicitly says that same-day requests are unavailable.
The useful Korean menu word is jeonchul (전출, “moving out”). On a gas-company site, it leads to the process for leaving the address. Its partner is jeonip (전입, “moving in”). These labels matter because a search for a generic account cancellation can miss the page designed for a household move.
The booking pages don’t use one national timetable
The clearest practical lesson comes from comparing provider forms rather than copying one moving checklist. The table below records what each official Korean page displayed on September 29, 2026.
| Provider page | What the page requires or states |
|---|---|
| Yeongnam Energy Service, Gumi | The move-out request is a prior reservation for a technician visit. Same-day applications are unavailable, and the displayed visit window is 9:00 a.m. to 5:00 p.m. |
| Kyungdong City Gas | The form has an information-and-consent step followed by date selection. It asks for mobile verification, a contact number for the technician, and the service location through an address or napbu beonho (납부번호, “payment account number”). |
| Yesco | The online move-out form is limited to household accounts. It displays a visit window of 9:30 a.m. to 4:00 p.m. and asks for the applicant, a visit contact, the address, the registered user, and a requested date and time. Other account types are directed to phone service. |
Those details apply only to the named pages. The provider’s own page controls the booking. A time quoted for Yesco should not be borrowed for Kyungdong, and advice to arrange everything on moving day conflicts with Yeongnam Energy Service’s explicit ban on same-day applications.
Why the Korean wording changes the task
The forms call this jeonchul yeyak (전출 예약, “move-out reservation”). They also refer to gisa bangmun (기사방문, “technician visit”). Together, those phrases frame the move as scheduled field service rather than a web-only account setting.
That distinction affects preparation. A resident may need a reachable mobile number, the exact service address, the name attached to the account, and a selectable visit slot. Kyungdong’s page can use a payment account number to identify the household, while also offering address selection when that number cannot be linked. Yesco separates household online requests from other uses. Yeongnam publishes a no-same-day condition.
The safest checklist is therefore short and supplier-specific:
- Confirm which company handles the current address before opening a form.
- Find the company’s current menu for jeonchul rather than relying on a general moving article.
- Prepare the registered user name, a mobile contact, the service address, and the payment account number if the form requests it.
- Choose an available date before moving day and read the displayed visit hours on that exact page.
- Check the applicant rules if the person submitting the form is not the registered customer.
A roommate or agent may need more than the address
The applicant rules are another place where a generic checklist loses important detail. Yeongnam Energy Service states that a third party other than the subscriber or the subscriber’s spouse must have the subscriber’s authorization. Kyungdong says a request for a household registered to someone else may be restricted. Its form also says the company can notify the contract holder and contact the number recorded with the supply contract to verify the request.
That makes the account name worth checking early when a roommate, landlord, employer, or relocation agent is handling the move. The official pages do not support a universal promise that any person with the address can complete the booking.
Keep the comparison local to each provider
This comparison covers three providers and their pages as displayed on September 29, 2026. It does not measure every supplier in Korea, and appointment conditions can change. Its value is the pattern visible across the original Korean forms: jeonchul is a dedicated move-out service, while the practical limits belong to the individual provider.
Before the boxes are loaded, finding that one Korean menu word reveals whether the form needs advance notice, whose identity it will accept, and which hours can actually be booked. That is more reliable than borrowing another provider’s cutoff.
