Each country has its own postcode, a system that originated in the United Kingdom and has evolved to a different style in each country. Here are some postal code formats for major countries:
US ZIP Code Format
The full U.S. code has 9 digits, the most basic 5 digits in the front, and 4 digits in the back. On the US ZIP Code Lookup website, you can check ZIP codes across the United States. For example: 15874-4585.
Canadian Postal Code Format
Canadian postal codes have 6 characters, including letters and numbers. Among them, the 1/3/5 digits are letters, and the 2/4/6 digits are numbers. For example: M3H4P5; H3P3K5.
UK postal code format
The British postal code (Post Code in English) is a mixture of English and numbers. The earliest postal code came from the United Kingdom. However, the format of postal codes in the UK is extremely complex, and there are many mixed formats of postal codes, and there is no special rule at all.
