IRLAND Personal Public Service Number (PPS)

Die zur Identifizierung der Steuerpflichtigen verwendete Nummer ist die Personal Public Service Number (PPS-Nummer). Diese Nummer wird vom Amt für soziale Absicherung vergeben, dient jedoch auch dem Finanzamt zur Identifikation von Steuerpflichtigen.

Abkürzungen

PPS : Personal Public Service

Aufbau

9999999P(A) : 7 Ziffern + apha-Prüfzeichen und optional Buchstaben A bis I und W

The format of the PPS number was defined as being nine characters in length, consisting of 7 digits in positions 1 to 7, followed by a check character in position 8, with either a space or the letter "W" in position 9. However, from 1 January 2013 a new range of PPS numbers were introduced by including an additional alphabetic character, other than "W", in position 9.

The character in position 8 still operates as the check character for all existing and new numbers, but the calculation used to decide this character has been revised to avoid any confusion between an old number and a new number using the same 7 numeric values in the first 7 positions.

The check character is calculated using a weighted addition of all the numbers and modulus calculation (known as Modulus 23). It therefore checks for incorrectly entered digits and for digit transposition (digits in the wrong order will alter the sum due to weightings).
