Frequently asked questions

What is the difference between a postal code and a ZIP code?

They do the same job under different national systems. ZIP code is the American term and is numeric — five digits, optionally plus four more. Postal code is the general term used elsewhere; Canadian ones alternate letters and numbers, and British postcodes mix letters and numbers in two blocks.

What is the difference between a postal code and an area code?

A postal code routes mail to a geographic delivery area. An area code routes telephone calls to a region. They cover different territories and are never interchangeable, even though both are tied to place.

How specific is a postal code?

It depends on the country. A US ZIP code usually covers a whole town or a district of a city, while a full UK postcode narrows down to a handful of addresses on one street, and a Canadian one can identify a single large building.

What is the meaning of postal code?

"postal code" (noun) means a short series of letters, numbers or both, added to an address so that mail can be sorted and delivered to the right area or street.
