verinum
High-performance validation and reference data library with a compiled Rust core, exposed to Python via PyO3.
- Identifier validation — IBAN, BIC, credit card, ISBN, ISSN, ISIN, LEI, EAN, EU VAT numbers
- Reference data — countries, subdivisions, currencies, languages, VAT rates
- Check digit algorithms — Luhn, Verhoeff, Damm, ISO 7064
- Offline-first — all validation and lookup works without network access
- Zero-allocation hot paths —
is_valid()functions are standalone, allocation-free implementations in the Rust core
Installation
pip install verinum
Prebuilt wheels are provided for Linux (manylinux + musllinux, x86_64 and
aarch64), macOS (Intel and Apple Silicon), and Windows (x64). On other
platforms pip will build from the sdist, which requires a Rust toolchain.
Usage
import verinum
# Validators
verinum.iban.is_valid("GB82 WEST 1234 5698 7654 32") # True
verinum.vat.validate("DE123456789")
# {'is_valid': True, 'compact': 'DE123456789', 'country': 'DE', ...}
verinum.credit_card.validate("4111111111111111")
# {'is_valid': True, 'brand': 'visa', ...}
# Reference data
verinum.countries.get(alpha2="DE")
verinum.currencies.get(code="EUR")
verinum.vat_rates.get("DE")
# Algorithms
verinum.algorithms.luhn_validate("4111111111111111")
# Client (optional wrapper)
from verinum import Client
v = Client()
v.iban.validate("GB82WEST12345698765432")
Validation semantics
is_valid(input)— offline format/checksum validation. Fast path, zero allocations. Standalone implementation, not a wrapper aroundvalidate().validate(input)— offline structured validation with normalization, typed error codes, and validator-specific metadata.verify(input)— future live registry validation (scaffolded, raisesNotImplementedErrorin v1).
