About Tax Identification Number (NIF)
The Tax Identification Number (NIF), commonly referred to as the Contributor Number in Portugal, is the unique nine-digit numeric identifier assigned by the Tax and Customs Authority (AT) to individuals and corporate entities for tax purposes.
This tool generates simulated and mathematically valid Portuguese taxpayer numbers (NIF). The generator separates entity types: Individuals (initial prefixes 1, 2, 3) and Companies/Corporate entities (prefixes 5, 6, 8, 9), calculating check digit using Modulo 11.
