Editorial interest 76/100 Selection signal · not a rating of the site

A Shopify app collects and validates regional tax IDs such as Spain’s NIF, Argentina’s CUIT, and Brazil’s CPF/CNPJ, then attaches them to orders.

Landing page captured for the 2026-09-08 issue.

Field notes

The app places a country-aware tax-ID field across the Shopify cart, cart drawer, thank-you page, and customer account. It applies check-digit rules for Spain, Argentina, Chile, Peru, Colombia, and EU VAT numbers, while also listing coverage for more than 80 additional countries. After browser and server validation, the identifier is written to order and customer metafields, and orders missing a valid value are tagged for follow-up.
