EU customs requires three product identifiers on B2C imports from 1 November 2026: your code (M-PID), the manufacturer's code (NS-PID) and, where one exists, a GTIN, EAN, UPC or ISBN (S-PID). Shopify Shipping fills them from product data; Mikata PID checks that data first, for any carrier: every variant, check digits, duplicates. Pro adds bulk fixes with a preview, supplier-sheet paste and CSV export for your carrier, Shipmondo or Shopify. It does not assign HS codes or file declarations.

• Checks every variant for M-PID, NS-PID and S-PID in one table
• Validates GTIN, EAN, UPC and ISBN check digits and flags duplicates
• Fix gaps in bulk, paste a supplier sheet, preview before writing (Pro)
• Export CSV for your carrier, Shipmondo or Shopify re-import (Pro)
• No server storage: data moves only between your browser and Shopify
