Delivery Control
Deliver Where You Choose, Block Where You Can't
Define exactly which postal codes can place COD orders — prevent undeliverable submissions before they create operational overhead.
What is Postal Code Limitations?
Not every business can deliver everywhere, and not every delivery zone is profitable. BuyEase's Postal Code Limitations feature gives you precise control over which geographic areas can submit orders through your COD form — preventing wasted shipping costs, failed deliveries, and Return to Origin charges from areas outside your actual coverage.
Create an allowlist of postal codes you actively serve, or a blocklist of codes you cannot or choose not to deliver to. When a customer enters an address in a restricted zone, a professional message explains that delivery is unavailable in their area — preventing the order from ever entering your fulfillment pipeline.
This feature is especially valuable for merchants expanding into new markets incrementally, or for businesses that experience disproportionate Return to Origin rates in specific geographic areas with unreliable last-mile delivery infrastructure.
Key Benefits
Why merchants choose Postal Code Limitations
Eliminate Undeliverable Orders
Block orders from postal codes you cannot fulfill before they create operational overhead, wasted shipping costs, and customer service burden.
Precise Geographic Expansion

Reduce High-RTO Areas
Block postal codes with historically high Return to Origin rates to immediately improve your delivery success metrics and overall margins.
