Welcome to the Kaldus Postal Service (Kal-Post). This agency provides all of the public mail services for every resident of the nation. Services such as DHL, FedEx, and UPS can still operate here, but they tend to be more expensive for the general use of mailing an envelope. This is where Kal-Post comes in. Kal-Post will deliver letters, and even packages for a reasonable rate. While they are not a monopoly, they are the only service that governments, and government owned businesses will use. They also offer a unique feature where one could use their NIN as the address. They are also integral with Kal-Stamps which is a metering service that will actually be affordable and with a program installed on every Kal-OS PC, this will make using the service very easy, even for a novice. Each post office will have vending machines for postage stamps which will mean less demand on the front desk operations. The goal is to only go to the front desk to acquire a package that is waiting for them.

Where the majority of measurements are metric, the postal service will use ounces since they are lighter than grams. This allows for a more fair price. It could be 75¢ for the first ounce, or $1.25. for the first gram. An ounce will likely support 4-5 sheets of paper, and the envelope. This will likely be confusing, but Kal-Post will sell scales for a reasonable price. One could also get their letter weighed for knowing exact postage. Those that uses Kal-Stamps should consider buying their own scale.
