Korea Post introduced a new supplementary letter service, named Tracked Ordinary Letter, positioned between ordinary letter and registered letter in terms of feature and price to expand customer choice.
When you send an ordinary letter, you may be worried about that your letter has been safely delivered to the addressee. You could choose the registered mail service for important documents. But for other documents and letters with lesser priority like wedding invitation or personal letter, registered mail of higher price is not an easy option. To help these customers and give them a wider choice, Korea Post introduced a new service with tracking and delivery notification features at a reasonable price, positioned between ordinary letter and registered letter.
