What is a Routing Guide? The Retail Vendor’s Survival Guide

What is a Routing Guide?

A routing guide is a retailer’s official document that spells out every rule a vendor must follow when shipping products to their distribution centers and stores. Think of it as the retailer’s shipping rulebook—covering approved carriers, delivery windows, packaging specifications, labeling requirements, and the penalties (chargebacks) for getting any of it wrong.

If you’re a D2C brand or first-time retail vendor, the routing guide is likely the single most important document you’ll receive during onboarding—and the one nobody warns you about. It typically arrives as a dense 30–100+ page PDF from your retail buyer or the vendor compliance team, and it contains everything from pallet height limits to the exact hour your truck must arrive at the receiving dock.

Every major retailer has their own routing guide, and no two are identical. Walmart’s routing guide has different rules than Target’s, which differs from Costco’s. If you supply multiple retailers, you need to track and comply with each one separately. Routing guide violations are one of the most common sources of retail chargebacks—making compliance not just a logistics detail, but a direct hit to your bottom line.

Why Every Retailer Has a Routing Guide

Retailers operate massive distribution networks. A single Walmart distribution center might receive hundreds of truckloads per day from thousands of different vendors. Without standardized shipping rules, the receiving dock would descend into chaos—wrong pallet sizes that don’t fit the racking, shipments arriving without appointments blocking dock doors, and unlabeled cartons that can’t be scanned into inventory.

The routing guide exists to prevent this. By mandating exactly how every vendor must prepare, label, and deliver their shipments, retailers can automate their receiving process and keep their supply chains moving efficiently. From the vendor’s perspective, the routing guide is non-negotiable—you either comply or you pay chargebacks. And enough chargebacks can end the relationship entirely.

How Often Routing Guides Change

Routing guides are living documents. Most retailers update theirs at least once per year, and some make changes quarterly. Walmart, for example, updates its transportation routing guide annually and publishes the updated version through Retail Link. Target communicates updates through Partners Online.

The problem for vendors is that changes can be subtle—a new pallet height maximum, a shifted delivery window, a new labeling requirement—and buried deep in the document. Missing a single update can trigger chargebacks on every shipment until you catch it. This is why vendors who supply multiple retailers need a systematic way to track routing guide versions and changes.

The Key Sections of Every Routing Guide

While every retailer’s routing guide is different, they all cover the same core topics. Here’s what you’ll find in virtually every routing guide and what each section means for your operations.

The labeling section typically references GS1-128 shipping labels and ASN (Advance Shipment Notification) requirements. The packaging section often includes retail-ready packaging and polybag and suffocation warning specifications. These are separate compliance topics with their own deep requirements—our dedicated guides cover each in detail.

Must Arrive By Date (MABD) and OTIF Explained

Two terms you’ll see repeatedly in any routing guide are MABD and OTIF. Understanding these concepts is critical because they form the basis of how retailers measure your shipping performance—and determine your chargebacks.

What is MABD (Must Arrive By Date)?

The Must Arrive By Date (MABD) is the deadline by which your shipment must be delivered to the retailer’s distribution center or store. It’s not a suggestion—it’s a hard cutoff. Miss the MABD and you face chargebacks, regardless of whether the delay was caused by your warehouse, the carrier, or weather.

The MABD is typically calculated backward from the date the retailer needs the product on the shelf. The retailer factors in their own receiving, quality inspection, and distribution timelines. By the time the MABD reaches you, there’s no slack in the schedule.

A critical distinction: the MABD is a delivery date, not a ship date. It doesn’t matter when you put the order on the truck—it matters when the truck arrives at the DC. This means you need to build in transit time when planning your ship date. If the MABD is Friday and transit is three days, you need to ship by Tuesday at the latest.

What is OTIF (On Time In Full)?

OTIF stands for On Time In Full—a scorecard metric that measures what percentage of your orders arrive by the MABD (on time) with the correct quantities (in full). It’s the single most important vendor performance metric at most major retailers.

OTIF Targets by Retailer

Walmart pioneered OTIF enforcement in 2017 and remains the most aggressive. Other retailers have adopted similar programs with varying thresholds and penalty structures.

OTIF scores are tracked on your vendor scorecard alongside other metrics like fill rate and case pack accuracy. Consistently low OTIF scores don’t just mean chargebacks—they can lead to reduced order volumes, loss of shelf space, or termination of the vendor relationship.

Routing Guide Requirements by Retailer

Each major retailer has unique routing guide requirements. Here’s what vendors need to know about the key differences between the biggest US retailers.

Walmart

Walmart’s routing guide is one of the most detailed in the industry. Vendors must determine whether they are Collect (Walmart arranges and pays for freight) or Prepaid (vendor arranges and pays for freight). This classification affects carrier selection, appointment scheduling, and billing. Collect vendors use Walmart’s preferred carriers and schedule through Walmart’s transportation management system.

Walmart’s OTIF program is the strictest in retail. As of 2024, Walmart sets separate targets: 98% on-time for Collect shipments, 90% on-time for Prepaid shipments, and 95% in-full. Vendors who fall below these thresholds face fines of 3% of the cost of goods sold (COGS) on non-compliant cases. All shipments require EDI 856 ASNs transmitted before the freight arrives at the DC. Pallet specifications, GS1-128 labeling, and appointment scheduling through Retail Link are all mandatory.

Target

Target’s routing guide emphasizes carrier compliance and delivery scheduling. Vendors must use Target-approved carriers for collect shipments and schedule deliveries through Ryder Online (for regional DCs) or Docklink (for flow DCs). Target sets a 100% On Time Arrival (OTA) goal and a 96% On Time Shipment (OTS) target, with non-compliance penalties of 3% of COGS (minimum $150 per occurrence).

Costco

Costco’s routing guide is notable for its strict packaging requirements. Pallets must not exceed 48″ × 40″ and have a maximum height of 52″ (including the pallet). Costco strongly discourages styrofoam (EPS) packing materials—use requires specific buyer approval—and requires specific stretch wrap specifications. Vendors must also meet Costco’s sustainability packaging guidelines, which are updated regularly.

Amazon

Amazon’s inbound routing guide (for Vendor Central suppliers) covers prep and packaging requirements, carton labeling, and shipment creation through Vendor Central. Amazon uses a different model than traditional brick-and-mortar retailers—shipments are often directed to specific fulfillment centers via Amazon’s routing system, and delivery appointments are managed through the Carrier Central portal.

Kroger

Kroger’s routing guide has additional temperature-control requirements for food and beverage vendors. Delivery appointments are managed through Kroger’s scheduling system, and vendors must comply with specific receiving window hours that vary by distribution center. Chargeback penalties range from $100 for packing list errors to $500 for missed appointments and up to $2,000 per item per division for poor pallet quality.

Common Routing Guide Violations and Their Costs

Routing guide violations result in chargebacks—deductions taken directly from your payment. Here are the most common violations and their typical costs.

How to Read Your Routing Guide: A Practical Walkthrough

Opening a 60-page routing guide for the first time is overwhelming. Here’s a systematic approach to extracting the information you actually need.

Routing Guide Compliance Strategies

Compliance isn’t about memorizing 60 pages. It’s about building the routing guide requirements into your systems and processes so compliance happens automatically.

Automating ASN generation is one of the highest-impact compliance investments you can make. ASN errors (late, missing, or inaccurate) are among the most common routing guide violations, and they’re entirely preventable with the right systems.

If you’re using a 3PL, verify that they are familiar with your specific retailers’ routing guides. Not all 3PLs handle retail fulfillment, and the difference between a 3PL that knows Walmart’s routing guide and one that doesn’t can be thousands of dollars in chargebacks per quarter. Ask your 3PL which retailers they currently serve and request their chargeback rates as a reference.

When Routing Guides Change (and They Will)

Routing guides are not static documents. Retailers update them regularly—sometimes with major structural changes, sometimes with small tweaks that are easy to miss but expensive to violate.

How Retailers Communicate Changes

Most retailers announce routing guide updates through their vendor portals (Retail Link, Partners Online, Vendor Hub). Some send email notifications to the vendor contact on file. The problem is that these notifications are easy to miss—they arrive alongside dozens of other portal alerts and operational emails. And in many cases, the retailer simply posts the updated PDF without a detailed changelog, leaving you to figure out what actually changed.

What Typically Changes

• ●OTIF thresholds: Retailers may raise the target percentage or increase penalty rates
• ●Carrier lists: Approved carriers are added, removed, or reclassified
• ●Packaging specifications: Pallet heights, stretch wrap requirements, or sustainability mandates
• ●Labeling requirements: New barcode formats, label placement rules, or data fields
• ●Delivery windows: Receiving hours, appointment scheduling rules, or seasonal adjustments
• ●Chargeback schedules: New violation categories or increased penalty amounts

How to Stay Current

The manual approach is to assign someone on your team to check each retailer portal monthly and compare the current routing guide PDF against the previous version. This works with one or two retailers, but becomes impractical when you supply five or more.

RetailerHub’s Version Intel feature tracks routing guide changes across all your retailers and highlights what’s new—so you don’t have to manually diff 60-page PDFs to find the one paragraph that changed. When a retailer updates their routing guide, you get an alert with the specific changes that affect your operations.

Routing Guide vs. Vendor Manual: What’s the Difference?

New vendors often confuse the routing guide with the vendor manual (also called the vendor compliance guide or supplier handbook). They’re related but distinct documents.

In practice, some retailers combine both into a single document, while others keep them separate. Walmart, for example, publishes a comprehensive vendor manual that includes routing instructions. Target maintains separate documents for transportation routing and general vendor requirements. Regardless of format, you need to know and comply with both sets of requirements.
