That $5,000/month shipping loss you’re blaming on “rising carrier costs”?
It’s probably 50 remote postcodes quietly destroying your margins.
Here’s the common setup: you offer free shipping nationwide because it converts. Orders roll in. Customers are happy. Then the invoices arrive, and suddenly, rural and remote deliveries are eating your profit alive.
You try WooCommerce’s built-in shipping rules. You try zones. You try free shipping thresholds.
None of it works by postcode, and definitely not by postcode + cart total.
That’s where things break.
1. Why This Problem Exists
WooCommerce was never designed for granular shipping logic.
At its core, WooCommerce shipping works on:
- Shipping zones (country/state)
- Simple conditions (free shipping over X)
What it doesn’t handle well:
- Excluding specific postcodes from free shipping
- Combining postcode rules with cart total
- Hiding or renaming methods dynamically
The moment you try to say:
“Free shipping everywhere except these 50 postcodes unless the cart is over $200”
…you’re out of luck.
Common workarounds like duplicating zones or stacking shipping methods quickly become fragile. One small change breaks checkout, confuses customers, or creates hidden edge cases you only discover after refunds pile up.
2. The Manual / Hacky Solutions (and Why They Fail)
Option 1: Do It Manually
You maintain a spreadsheet of remote postcodes.
You manually adjust rates or refund customers after checkout.
Cost:
- Hours every week
- Inconsistent customer experience
- Guaranteed human error
This doesn’t scale past a hobby store.
Option 2: Use a “Free Shipping Restriction” Plugin
Most plugins let you:
- Exclude postcodes or
- Set a cart total condition
But rarely both together, cleanly.
You end up with:
- Conflicting rules
- Shipping methods are randomly disappearing
- No visibility into why a rate was shown or hidden
Option 3: Custom Code Snippets
Yes, you can hook into WooCommerce filters.
Until:
- WooCommerce updates
- Your theme changes
- A new plugin conflicts
Now you own a shipping logic codebase you’re afraid to touch.
That’s not a business, that’s technical debt.
3. The Clean Solution with RuleHook
RuleHook was built for exactly this problem: rule-based shipping logic without hacks.
Here’s how you solve it properly.
Step-by-Step Setup
- Create a new rule
- Conditions
- Shipping Postcode → is in list (your remote postcodes)
- Cart Total → less than $200
- Actions
- Hide “Free Shipping”
- Show a paid shipping method (or increase cost)
What Happens at Checkout
- Customer enters their address
- WooCommerce calculates shipping
- RuleHook evaluates the rules in real time
- Free shipping is automatically hidden for remote postcodes under your threshold
No broken zones.
No duplicate methods.
No surprises.
Customer Experience
- Urban customers still see free shipping
- Remote customers see realistic rates
- Checkout remains fast and predictable
- You stop bleeding money silently
4. Edge Cases to Consider
This approach is powerful, but be intentional.
When this might NOT work
- If your carrier already includes remote surcharges dynamically
- If you rely on flat-rate shipping only
Other conditions to combine
- Weight (heavy items to remote areas)
- Product tags (e.g. oversized items)
- Shipping class (freight vs parcel)
Testing checklist
- Test known remote postcodes
- Test cart totals just below and above the threshold
- Test logged-in vs guest checkout
- Test mobile checkout (always)
Closing
If you’re offering free shipping nationwide, you’re almost certainly overpaying for remote deliveries; you just can’t see it yet.
Hiding shipping methods by postcode combined with cart total is the difference between:
- Guessing
- And controlling your margins with precision

Related scenarios you might care about:
- Hide express shipping for PO boxes
- Increase shipping cost for oversized items
- Disable free shipping for international orders
Shipping shouldn’t be a gamble.
It should be a rule.
