A post code is a series of letters and/or digits added to a postal address to aid in sorting mail. It's also known as a postcode, post code, PIN code, or ZIP code, depending on the country.
Purpose of Post Codes
Post codes serve a crucial purpose in the efficient delivery of mail. They allow postal services to:
- Automate Sorting: Post codes enable automated sorting machines to quickly and accurately route mail to the correct delivery area.
- Speed Up Delivery: By narrowing down the geographic area, post codes reduce the time it takes for mail carriers to deliver items.
- Improve Accuracy: They minimize the chance of mail being misdirected due to similar addresses or incomplete information.
- Facilitate Mapping and Geolocation: Post codes are also used in mapping software and geographic information systems (GIS) to pinpoint locations.

| Country | Post Code Format | Example |
