How Ireland tax IDs are formatted
In Ireland, the tax identifier is commonly known as Personal Public Service Number (PPS Number). The expected format is 7 digits + 1-2 letters (e.g. 1234567A or 1234567AB). Teams usually need a Ireland PPS Number check around tax filing, social welfare, healthcare, or before a record moves into billing, onboarding, or compliance review.
Valid examples

Invalid examples
- 1234567 (Missing letter)
- 12345A (Too short)
What this validator checks
Format and length
Confirms the number follows the expected Ireland pattern: 7 digits + 1-2 letters (e.g. 1234567A or 1234567AB).
Useful examples
Shows valid and invalid-looking samples so you can compare spacing, separators, letters, and digit counts before submitting real data.
Letter placement
Checks letter positions where the PPS Number format requires alphabetic prefixes, suffixes, or program identifiers.
When people usually check this number
- Tax filing
- Social welfare
- Healthcare
- Employment
A format match does not prove that a Ireland tax ID belongs to a specific person or business. Use the result as a first-pass data quality check, then confirm sensitive cases with official records.

How to check a Ireland PPS Number
Use this check before a record reaches billing, tax reporting, or manual review.
Enter the PPS Number
Paste or type the Ireland tax identifier exactly as it appears in your source record. Spaces and separators are fine when they are part of the expected format.
Review the format result
Check whether the number matches the known Ireland structure, including length, separators, letters, and checksum rules where public guidance includes them.
Confirm important records
For onboarding, tax reporting, or compliance work, treat the result as a data-quality signal and confirm high-risk records with Revenue Commissioners or your internal process.
