When mailing an envelope or postcard, leave at least the bottom 16 millimeters (5/8 inch) blank on both front and back. (The postal service's reading and sorting machines might need this space to print bar codes on your mail.)
Basic address formatting guidelines from the An Post website as of 2013, with additions for mailing from outside Ireland to Irish addresses:
You should write your address in Ireland using the following guidelines:
- The maximum number of lines for an address is 6, or when mailing from outside Ireland to Irish addresses, possibly 7 including IRELAND as the bottom line.
- Each line should start at the same distance from the left hand edge of the cover, i.e. the address should not be written in the indented format.
- Each line should be limited to 32 characters.
- Individual characters should have a minimum height of 2mm (5/64 inch), a maximum height of 7mm (8/32 inch) and a maximum width of 7mm (8/32 inch). (So character height and width of 1/4 inch to 1/8 inch are certainly within the specified size range.)
- The address must be written in a compact form without a blank line between the Post Town or County Name (if required) and the other elements of the address. It is important that no part of the address is underlined.
Note: The Official Postal Address does not contain any abbreviations and An Post recommends that you use the full spelling when addressing a mail piece, for example Road not Rd.
A few addresses are special cases:
An Post says "The name of the locality or second thoroughfare should...always be included in the address where it is necessary to distinguish between two or more streets in the same postal district, for example"
Pembroke Cottages Ringsend Dublin 4 OR Pembroke Cottages Donnybrook Dublin 4
To get these "postal district numbers" for areas that have them, use the next section for address correction.
Postage calculators and tables showing how much postage you need to mail or ship to and/or from Ireland are at the International Postal Rates Page.
