Trader Information

Overview

Merchants shipping across borders often must capture a buyer's tax identification number - a VAT or EORI number for the EU, PAN for India, CPF for Brazil, RFC for Mexico - before an order can be fulfilled or invoiced. Checkout Tax ID adds exactly the right field to the checkout, for exactly the right countries, with no custom code.

You define rules in the admin panel: pick one or more countries, give the field a label and tooltip, choose how it is validated (exact length, a length range, or a custom pattern), and decide whether it is required. When a customer selects a matching shipping country, the field appears automatically. The submitted value is saved to the order with a snapshot of its label, shown on the order detail page, and available as an optional, filterable column in the Sales →Orders grid.

Key Features

Rule-based, no code - add, edit, or remove tax-ID fields entirely from the admin panel
Per-country targeting - one rule can cover many countries (for example one EORI rule for 28 EU countries plus Great Britain).
Separate Residential / Commercial mode - present two independent fields per country, each with its own label, validation and required flag.
Ten pre-configured rules - India, Brazil, Indonesia, Mexico, Saudi Arabia, South Korea, Turkey, Vietnam, Bangladesh, and EU + GB (EORI).
Flexible validation - exact length, length range, or a custom pattern per rule.
Saved to the order - value plus a label snapshot, visible on the order page.
Order grid column - opt-in Tax ID column with server-side filter and sort.
Clean and self-contained - one dedicated table, no changes to native sales tables, no external services.
Fully translatable - every label, tooltip and field name.
