# idsmith

Validate and generate checksum-correct **IBANs**, **personal IDs**, **bank accounts**, **credit cards**, **SWIFT/BIC**, **company IDs**, **driver's licenses**, **tax IDs**, and **passports** across multiple countries.

Built for developers and QA engineers who need a robust way to validate existing identifiers or create realistic, algorithmically valid test data.

## Features

- **Validator + Generator** — verify existing strings or create new data
- **124 IBAN countries** — full IBAN registry coverage with mod-97-10 checksum validation
- **159 bank account formats** — US ABA routing, MX CLABE, AU BSB, IN IFSC, AR CBU, NG NUBAN, BR mod-11, etc.
- **97 personal ID formats** — checksum-verified (SSN, CPF, Aadhaar, Resident ID, and more)
- **250 company ID formats** — VAT numbers, EINs, and Business IDs with major economy checksums
- **Universal Credit Cards** — Visa, Mastercard, Amex, Discover, JCB, and Diners Club with Luhn support
- **SWIFT/BIC** — valid 8 and 11 character codes with ISO country positioning
- **79 driver's license formats** — with country-specific checksum and format validation
- **80 tax ID formats** — with checksum validation (PAN, TIN, CPF, SIN, Steuer-IdNr, USCI, Partita IVA, NIF, BSN, RFC, and more)
- **79 passport formats** — with country-specific format validation

## Available in 3 Languages

| Platform | Package | Install |
|----------|---------|---------|
| **Rust** | [idsmith](https://crates.io/crates/idsmith) | `cargo add idsmith` |
| **Python** | [idsmith](https://pypi.org/project/idsmith/) | `pip install idsmith` |
