An arrival-probability display helps with planning before purchase, but it is not a booking for a guaranteed delivery day. Atomy Korea explains that the estimate uses recent delivery information from the preceding 30 days.
Check the destination used by the estimate as well. The page says the default delivery area is used, and without an address it can display a Seoul Jongno reference location.
Use different information before and after ordering
| Stage | Information to use |
|---|---|
| Comparing a product | Its delivery estimate and the destination behind it |
| Order placed, not dispatched | Your order status and any dispatch notice |
| Parcel dispatched | The tracking information for that shipment |
| Several shipments | Each parcel’s own tracking record |
A promising percentage for Seoul does not establish the same arrival pattern for your own address. Signing in or selecting a destination is worthwhile before using the estimate to plan.
After dispatch, move your attention to the actual shipment. A product page may still show a general forecast while your parcel has its own progress and exceptions.
Work backwards from a gift deadline
If you need to hand over a gift on Friday, delivery is only one step. You may also need time to inspect the contents, wrap them and travel to the recipient.
Keep a margin suited to that situation. There is no fixed number of extra days in this article that makes every shipment safe, particularly around holidays or when products ship separately.
If the tracking stalls or the expected date matters, contact the official support channel with the order and shipment reference. Ask about that parcel rather than treating the product-page probability as a delivery guarantee.
