Could you build this?
Partial A basic checksum validator is simple, but compiling and maintaining the exact official validation algorithms, regex specs, and ICAO 9303 checksum rules across 200+ national ID formats requires extensive regulatory document research.
What it would actually take: The service is a lightweight REST API (built in Go, Rust, or Node) that takes document strings and validates format/check digits without database persistence. The core barrier is assembling the verified domain logic and checksum specifications (mod 11, mod 97, Luhn variants, national ID formulas) for 195+ jurisdictions from obscure government technical standards. Requires specialized data gathering and testing against real-world sample patterns to avoid false negatives.
