A Beep Check is the date a guide was last checked. You will see it on every guide as a “Last checked” badge at the top and a “Beep Check: verified” line near the end.
What We Check
Prices, opening days, rules, routes and booking steps are checked against official sources, such as the operator, the city, the ministry or the venue itself, and not against what a partner tells us.
What The Date Means
The date is the day the facts in that guide were last checked. Korea changes fast, so older dates are a reason to double check the details that matter to you, such as a ticket price or a closing day.
When We Are Not Sure
If a date or detail is not confirmed yet, we say it is “expected” or tell you to check before you go. We do not fill gaps with guesses. A station exit is only marked once we have checked it ourselves.
Spotted Something Off
Tell us on the Contact page and we will recheck it. To see how the site pays for itself, read how Seoul Sunbae makes money.
