Does Shopify validate EU VAT numbers?

Yes, since February 2026 — but only if your store uses Shopify Tax for the EU or the UK. Shopify then offers an optional Company VAT number field in checkout, checks the number against VIES and applies the reverse charge to eligible cross-border orders. It works for guest and Shop Pay checkouts, not for B2B-specific checkouts, and when VIES can’t answer, VAT is charged.

When a signed-in business buyer enters a valid VAT number from another EU country in the Shopify cart, Fedev — EU VAT & VIES removes the VAT at checkout and keeps the VIES check in your VAT records.

Everything below about Shopify comes from its help page Validating VAT numbers and its changelog of 25 February 2026, checked on 8 November 2026. Shopify changes these features; check the help page before you decide.

What Shopify’s built-in validation does

• Where: a Company VAT number field in checkout, which you set to Optional in your checkout settings. It is off by default.
• Who can use it: stores that use Shopify Tax to calculate tax in the EU or the UK. Shopify’s help page names no plan requirement.
• Which checkouts: guest checkout and Shop Pay. Shopify says validation “isn’t currently available for B2B-specific checkouts”.
• Where the order ships from matters: the exemption follows the fulfillment location, not the store address. You need an active fulfillment location in the EU; EU-to-UK orders qualify, UK-to-EU and UK-to-UK orders don’t.
• What it keeps: a valid number is saved to the customer profile for future orders, and the VAT invoice gets the note “Reverse Charge Mechanism: Recipient responsible for VAT”.

What it leaves out

• No answer from VIES means VAT. If VIES can’t complete the check, the exemption isn’t applied and VAT is charged, with no manual override. The order isn’t flagged for you to look at later.
• Reduced rates in tax-inclusive prices. With dynamic tax-inclusive pricing on, Shopify adjusts the displayed price by the destination’s standard rate; reduced rates from product tax categories and tax overrides aren’t applied to that adjustment, so the price shown can differ from the tax charged.
• No consultation reference. The help page doesn’t mention storing the reference VIES issues for a check, the proof that the number was valid on the day of the sale.
• Stores not on Shopify Tax. Without Shopify Tax for the EU or the UK, the field isn’t available.

Built-in field or an app?

Shopify’s field is probably enough if you already use Shopify Tax, your business buyers check out as guests or with Shop Pay, and you are content with VAT being charged when VIES is down.

An app fits better if you don’t use Shopify Tax, your business buyers sign in to their customer account, you sell reduced-rate products, or you want the VIES reference and a record of every check on file for a tax authority. How Fedev — EU VAT & VIES works, how its live VIES check works and the audit trail it keeps.

Before you rely on either

Check a few numbers by hand with the free EU VAT number check, and if a check fails, see what each VIES error means. Put the reverse-charge wording on your invoices — the reverse charge invoice wording generator writes it in English and your own language.
