 | | A postal code is a series of letters and/or digits appended to a postal address for the purpose of sorting mail. |
 | | Although postal codes are usually assigned to geographical areas, sometimes this is not the case: special codes may be assigned to institutions with large volumes of post, such as government agencies and large commercial companies. |
 | | Dublin, Ireland still uses postal district numbers, as postal codes are not used in the country at all. |
