South Korea passport guide
This page is written around a South Korea passport and the decisions that affect a real Benin trip: exemption status, the travel document, first entry date and whether the route needs re-entry.

Nationality check
Benin's official eVisa FAQ says foreign nationals can submit an eVisa application online and separately gives African nationals a general 90-day visa-free rule. A South Korea passport comes from East Asia, so do not assume that African-national rule covers this trip.
Before purchasing an eVisa, confirm whether your exact passport has any separate exemption. If a visa is required, use the published eVisa choices as the starting point rather than relying on a generic travel-site label.
Imagine a South Korea traveller taking a multi-country trip returning through Benin before the flight home. The visa decision should follow that route. If there is only one arrival, repeated-entry permission may add no value; if Benin appears twice in the itinerary, the entry question changes immediately.
For this route, the paperwork is less complicated when the travel plan is already settled. The passport, first entry date and number of intended entries should all be decided before the online form is opened.
Published visa choices
The figures above are the government fees published for self-service online applications. They do not include separate assistance or banking charges.
Travel document
The application begins with passport information for a reason: the authorization is connected to that document. A typo in the number is not the same kind of mistake as a typo in an informal note.
For travellers departing from South Korea, it is also worth checking that airline bookings use a name format that can be reconciled with the passport. Minor formatting differences are common, but the visa form itself should follow the travel document.
After submission
After submission, avoid creating a second application simply because an email is not instantly visible. First check the payment confirmation and the application reference.
Nothing in the process benefits from guesswork. Use the physical passport, the actual itinerary and a payment method you control, then keep the application reference after submission.
Dates and route
Check the first day you expect to enter Benin, not simply the day you leave home. Connections and overnight travel can make those dates different.
Single entry is for one arrival. Multiple entry matters when the itinerary deliberately takes you out of Benin and back again during the visa period.
Application window
If departure is close, do not interpret '1–96 hours' as a guarantee. The official wording describes how long processing can take, while the seven-day recommendation is the safer planning advice.
Card payment
A failed payment does not necessarily mean the visa data is wrong. It can be a card-security issue, which is why it helps to separate form review from payment troubleshooting.
Start with the passport nationality and any applicable exemption. If a visa is required, then compare the published eVisa duration and entry options against the itinerary.
Benin states that eVisa validity begins on the intended date of entry entered in the travel-data section.
The published self-service fees are €50 for 30-day single entry, €75 for 30-day multiple entry and €100 for 90-day multiple entry.
Keep the application number sent by email after confirmed payment because it is used for status tracking.
Check the passport, the first Benin arrival date and every planned re-entry. If those three facts are settled, the visa choice is much easier to judge.
