Warehouse efficiency isn’t just a nice-to-have—it’s a necessity. That’s why many businesses turn to zone picking, a fulfillment strategy that can improve operations and worker productivity. But is it right for you?
Let’s explore how zone picking can elevate your warehouse efficiency.
By the end of this guide, you’ll understand:
- What zone picking is and how it works
- The key benefits and potential challenges
- How to implement this strategy in your warehouse
What is zone picking?
Orders are completed by either passing items between zones (known as “pick and pass”) or by moving the order through the zones sequentially.
For example, in a retail warehouse, you might have one zone for bulky furniture that requires special handling equipment, like pallet jacks, while another zone is dedicated to smaller items like electronics or clothing that can be handpicked.
This way, workers become specialists in their zones, and the order moves smoothly from one section to the next until it’s complete. This approach reduces time spent crisscrossing the warehouse and keeps operations running efficiently.
The key to making this strategy work for you? As Rickerson says, technology:
Example zone picking workflow
Curious how this works in practice? Here’s a typical zone picking workflow:
- Order receipt: Orders are received and logged into the warehouse management system.
- Order allocation: The WMS assigns each item to the correct zone, streamlining the picking process.
- Zone picking: Workers in each zone pick the items assigned to their zone.
- Order consolidation: Items picked from different zones are brought together for order consolidation.
- Packing and shipping: Consolidated orders are packed and prepared for shipping, streamlining your overall picking and shipping operations and reducing delays in getting orders out the door.
Importance in warehouse management
Zone picking can be a game-changer. Here’s how it can improve your warehouse management process:
- Efficiency: By assigning workers to specific zones, you minimize travel time. Workers can spend less time moving and more time picking.
- Specialization: When workers stick to one zone, they become more familiar with their zone, reducing errors and speeding up the process.
- Scalability: You can easily scale zone picking to accommodate varying order volumes, making it ideal if you experience fluctuating demand.
- Reduced congestion: By limiting workers’ movement to specific zones, you’ll reduce warehouse congestion and improve overall operations.
How zone picking differs from other picking methods
Zone picking is distinct from other picking methods in several key ways:
- Single order picking: In single order picking, workers pick items for one order at a time. This method can lead to significant travel time and inefficiency, especially in large warehouses.
- Batch picking: In batch picking, workers pick items for multiple orders simultaneously. While this method can reduce travel time, it may lead to complexity in sorting items for different orders.
- Wave picking: Wave picking involves picking items for multiple orders in waves or batches. This method is typically used for high-volume operations but can result in congestion and longer fulfillment times if not managed properly.
- Cluster picking: In cluster picking, workers use multi-bin carts to pick and sort items for multiple orders concurrently. This method eliminates separate sorting steps but may be less efficient for high-volume, homogeneous picks.

How zone picking works
Creating effective zones in a warehouse starts with careful planning and the right tools.
Zone layout and design
Effective zone layout and design are crucial for optimizing warehouse operations. Consider the following key steps when planning your zone-based system:
- Analyze product data: Study product dimensions, weights, and picking frequencies to determine optimal storage locations.
- Define zones: Divide the warehouse into zones based on product categories, picking volumes, or other logical groupings.
- Assign workers: Allocate workers to specific zones, ensuring each worker is familiar with their assigned area.
- Optimize paths: Designate clear paths for picking and moving items between zones to avoid congestion.
Examples of typical zone layouts
To better understand how these principles can be applied, let’s look at some common zone layouts used in warehouses:
Product type zones: Group similar products, such as electronics, clothing, or perishables.
ABC zones: Use ABC analysis to categorize products by picking frequency, with A-items (high frequency) near dispatch areas and C-items (low frequency) further away.
Temperature-controlled zones: Designate areas for products requiring specific temperature conditions, such as frozen, refrigerated, and ambient zones.
Technology
Implementing a successful zone picking system requires the right technology to support your operations. Here are some essential tools and systems to consider:
- Warehouse management system: Centralized system for managing inventory, tracking orders, and coordinating zone picking.
- Shelving and racking: Optimize shelving and racking systems to accommodate various product sizes and weights.
- Conveyor systems: Use conveyors to move items efficiently between zones.
- Pick carts and totes: Equip workers with pick carts and totes designed for easy maneuverability within zones.
- Labeling and signage: Clearly label zones and include directional signs to guide workers and minimize errors.
- RF scanners: Handheld devices used by pickers to scan items, ensuring accuracy and real-time inventory updates.
