Do some addresses in South Korea have no postal code?
I ordered something from Korea and wanted to return a few items.
I was sent the return address by email, but there is no postal code.
Is this normal for Korean addresses?
Will DHL still accept it?
Here there is information from the World Post Office to address shipments to Korea: https://www.upu.int/UPU/media/upu/PostalEntitiesFiles/addressingUnit/korEn.pdf
A five-digit postal code is standard there.
