International Postal System

The International Postal System is a global network that facilitates the sending and receiving of mail between countries. It involves national postal services, like the United States Postal Service or Royal Mail, collaborating through agreements to ensure that letters and packages can be delivered across borders. This system standardizes postage rates, tracking, and delivery times, making international shipping more efficient. When you mail a letter abroad, your local postal service handles it initially, then transfers it to the destination country's postal service for final delivery, ensuring that items reach their intended recipients anywhere in the world.
