ZIP / Postal Code in Bratislava
A postal code (PSC) is a series of numbers (or even letters) which is an essential part of the address and is used for routing and quick sorting mails. It serves the same purpose as ZIP code system in the US. When sending a letter or a package to Slovakia, it is important to include the postal code because although it may arrive to the place without the PSC as well, it is more likely to get lost during transit.
