Short answer — South Korea
A booked appointment must carry the passport number you will physically present. Most portals allow a passport-number edit before a cut-off, typically 24 to 72 hours before the appointment; after that the counter rejects the mismatch and you must rebook.
Why this happens
Biometric and identity checks match the appointment record to the document at the counter. Any mismatch fails validation.
At Korea Visa Application Centre in India, Embassy of the Republic of Korea sets the underlying rule and the centre applies it at the counter, so the fix below is the same whichever Indian city you apply from.
