It handles CNPJ (corporate tax ID), CEI (business registration), CPF (individual tax ID), PIS/PASEP (social security), CEP (postal codes), and IBGE municipal codes. The library accepts both formatted strings and raw numeric input, auto-corrects missing leading zeros in integers, and treats missing values (None, NaN) as invalid rather than raising errors\u2014useful for data pipelines with incomplete records.\n\nBeyond validation, it provides formatting functions to display identifiers in standard Brazilian notation, parsing functions to extract components (firm ID, establishment number, check digits), and utilities to clean formatting. It recently added support for alphanumeric CNPJ format introduced in 2026. The package has no external dependencies and supports Python 3.9 through 3.14, making it lightweight for integration into larger systems.","worth_installing":"Yes. The package is actively maintained, has zero known vulnerabilities, imposes no dependency overhead, and solves a specific domain problem well. Install it if you work with Brazilian identification numbers in production systems or data pipelines."},"id":"brazilnum","links":{"html":"https://skillfed.io/packages/brazilnum","md":"https://skillfed.io/packages/brazilnum.md","pypi":"https://pypi.org/project/brazilnum/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-24","license_spdx":"MIT","license_treatment":"permissive","name":"brazilnum","python_support":"supports_current","summary":"Validate Brazilian CNPJ, CEI, CPF, PIS/PASEP, CEP, and municipal numbers"},"popularity":{"monthly_downloads":337580,"position":7447,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.10.0"}
