Stop losing orders to bad addresses

Every undeliverable package costs you shipping fees, support tickets, and a customer who may never order again. AddressPilot catches address problems while the buyer is still at checkout — before the order ever ships.

Catch problems before they become returns

A configurable rules engine checks every address at the moment of checkout, not after the fact. Turn on only the rules you need:

• Missing house numbers — one of the most common causes of failed first-attempt deliveries
• PO boxes — block them instantly if your carrier can’t deliver to one
• Blocked zip/postal codes — keep out specific codes you can’t service
• Military addresses (APO/FPO/DPO) — block or allow, your choice
• Address line length & special characters — stop malformed entries before they reach your fulfillment team
• Germany: DHL Packstation & Paketshop validation — enforce complete Packstation numbers and Postnummer, or block Paketshop pickup points entirely

Every rule comes with a sensible default message — or write your own in your own words.

Real-time, carrier-grade suggestions — for Shopify Plus

On Shopify Plus, AddressPilot goes further: as the buyer types, it suggests verified, corrected addresses right inside checkout. The buyer always chooses — nothing is ever silently rewritten behind their back. It’s the difference between hoping an address is right and knowing it is, before the order is placed.

Built to be fast and trustworthy

• No added checkout latency. The rules engine runs as a native Shopify Function — compiled, sandboxed, and executed in milliseconds, right inside Shopify’s own checkout.
• No order access. AddressPilot never requests permission to read or modify your orders. It only ever looks at the address fields in front of the buyer, nothing else.
• No customer data overreach. Name, email, and phone number are never touched — only the address being typed.
• Free to install. No billing step, no hidden tier required to get the core protection running today.

How it works

1. Turn on the rules you want. Pick from PO box blocking, missing house numbers, zip restrictions, and more.
2. Activate it in checkout. One click in Shopify’s checkout rules settings, and it’s live.
3. Buyers get instant feedback. Bad addresses are flagged inline, with a clear message on exactly what to fix.
4. Plus merchants get live suggestions. Verified address autocomplete, confirmed by the buyer, every time.

Fewer failed deliveries. Fewer refunds. Happier customers.
