Ireland Tax ID Numbers

For Individuals, Example: 9234567AA
The Irish Personal Public Service Number (PPS) is 8 or 9 characters in the format NNNNNNNAA and it includes a checksum. The PPS is issued by the Department of Social Protection but is also used by the Revenue Commissioners to identify taxpayers. PPS-numbers are issued automatically on birth registration for children born in the country. Anyone else must make application at an office of the Department of Social Protection.
Tax Reference Number (TRN)
For Entities, VAT, Example: IE 1234567FA
The Irish Tax Reference Number (TRN) is 8 or 9 characters in the format NNNNNNXAA with an optional prefix of IE when used as a VAT number. A TRN is issued by the Revenue Commissioners when a non-natural person registers for tax, and is subsequently used by the Revenue Commissioners to identify those taxpayers. Non-natural persons can be Companies, Partnerships, Trusts, and Unincorporated Bodies and it is not reported on official documents of identification.
