Parcels to consumers in Korea need the recipient's personal customs clearance code (PCCC), or customs holds them. Shopify collects it at checkout; the app checks each order shipped to Korea: P + 12 digit format, plus the recipient phone and 5-digit postal code customs matches against the code. Each order is tagged pccc-ok, pccc-missing, pccc-invalid or pccc-business. Missing or invalid: the customer gets a request email in Korean and English, reply-to your store. The code is never stored.

• Tags each order pccc-ok, pccc-missing, pccc-invalid or pccc-business
