New GS1 US research suggests warehouses relying on 1D barcodes carry hundreds of thousands of dollars in avoidable cost, making 2D barcodes a direct lever on operational performance. The findings quantify how labeling design now shapes error rates, labor spend, and the speed of information through distribution networks.
Error Costs Expose Limits of 1D Workflows
Facilities that still depend on linear barcodes absorb a sizable penalty in day-to-day execution. The GS1 US study estimates that a typical site running predominantly on 1D codes incurs more than $800,000 a year through shipment mistakes, rescanning, and relabeling activity. The largest contributor is mis-shipped or mis-recorded product, with average facilities spending about $696,000 annually on shipment errors alone. Additional labor for rescanning accounts for roughly $87,826, while relabeling adds around $31,871.
These costs map directly to friction at the scan point. Organizations using mostly 1D barcodes report a first-pass scan failure rate of 7 percent, along with a relabeling rate of 1.5 percent. Each failed scan stalls material flow, creates rework, and elevates the risk that cartons or pallets leave the building with the wrong data attached. Survey responses also point to variation in supplier labeling as a root cause. Many facilities receive cartons with multiple barcodes in different formats and positions, forcing workers to pause, inspect, and guess which symbol will drive the right system transaction.
The report, based on responses from 400 U.S. organizations across retail, manufacturing, logistics, transportation, hospitality, and healthcare, highlights how inconsistent label standards ripple through operations. About 31 percent of respondents said labels with several barcodes increased the likelihood of scanning the wrong symbol. Another 29 percent reported that this label complexity slowed down scanning overall. One 3PL operator cited in the research described frequent pallet break-downs and manual item checks when supplier labels fail to meet internal standards, along with extra training just to navigate multiple codes on a single label.
2D Codes Consolidate Data and Labor
The same analysis models a different cost profile for facilities that have adopted 2D barcodes as the primary identifier. When labels carry 2D symbols capable of encoding more data in a single scan, the study estimates annual costs drop to about $302,253 per site. The implied savings compared with 1D-based workflows exceeds $515,000 per facility. That gain comes from a mix of fewer shipment errors, lower manual relabeling, and faster throughput at each scan station.
2D barcodes can embed product identifiers alongside lot, batch, expiration date, and serial information on one symbol. Researchers link this to better inventory accuracy, stronger traceability, and more reliable fulfillment, since fewer manual lookups or secondary scans are needed to complete a transaction. Gena Morgan, vice president for global standards at GS1 US, notes in the report that 2D formats help clear longstanding scan inefficiencies and enable richer product transparency. When workers scan once and capture all relevant attributes, exception handling drops and the same labor covers more volume.
The operational implications extend beyond the four walls of the warehouse. Industry reports show that end-to-end visibility efforts often struggle when upstream partners apply different identifiers or omit key attributes at the unit or case level. A 2D standard that travels from production line through packing, transport, and final distribution gives planning, quality, and customer teams access to the same data without reconciliation. In regulated sectors that rely on lot-level or item-level traceability, encoding this information directly into the code supports faster recalls and audit response.
The Bigger Challenge Lies Outside The Warehouse
The economics of 2D barcodes are becoming easier to quantify, but capturing the full value depends on coordination beyond a single facility. Many distribution networks still operate with a mix of suppliers, contract manufacturers and logistics providers using different labeling practices and data standards. As traceability requirements increase and fulfillment networks become more interconnected, the quality of information attached to a product can matter as much as the movement of the product itself. Companies that standardize identification across trading partners gain cleaner data, fewer exceptions and greater confidence in the transactions that flow through their networks every day.
