ec-validator

High-performance validation library for Ecuadorian government IDs and financial data.

Quick Start

use ec_validator::{cedula, ruc, iban};

// Validate a Cédula (national ID)
assert!(cedula::validate("1713175071").is_ok());

// Validate a RUC (taxpayer ID)
assert!(ruc::validate("1713175071001").is_ok());

// Validate an Ecuadorian IBAN
assert!(iban::validate("EC8912345678901234567890").is_ok());

Validation Rules

Cédula de Identidad (10 digits)

The Ecuadorian national ID uses a Mod-10 algorithm. First two digits must be a valid province code (01–24). Third digit must be 0–6 for natural persons. The tenth digit is a check digit calculated using alternating weights [2,1,2,1,2,1,2,1,2].

RUC (13 digits)

The Registro Único de Contribuyentes has three variants:

• Natural Person (3rd digit 0–5): First 10 digits must pass Cédula validation; establishment code (digits 11–13) must be 001–999.
• Juridical Entity (3rd digit 9): Province code 01–24; check digit at position 10 using Mod-11 weights [4,3,2,7,6,5,4,3,2]; establishment 0001–9999.
• Public Entity (3rd digit 6): Province code 01–24; check digit at position 9 using Mod-11 weights [3,2,7,6,5,4,3,2]; establishment 0001–9999.

IBAN (24 characters)

Ecuadorian IBANs follow ISO 13616. Must start with "EC", be exactly 24 characters, and pass Mod-97 validation after rearranging (first 4 characters moved to end).
