Barcode Abbreviation

What Is a Barcode Abbreviation?

A barcode abbreviation is a short code that names a barcode standard, a data field, or an identifier type. These labels appear on scanner screens and shipping documents. They are not the barcode itself. They tell you what kind of data the barcode holds and where that data goes once the scanner reads it. GS1, the global body that sets barcode standards, describes its specifications as the shared language of business at gs1.org/standards/barcodes. Knowing the abbreviation tells you what the scanner will do with the data it reads.

Barcode Abbreviations for Product Identification: UPC, EAN, and GTIN

UPC, EAN, and GTIN are the 3 abbreviations that identify what a product is. They appear on item labels, inbound cartons, and supplier documents.

What does UPC stand for in a warehouse context?

UPC stands for Universal Product Code, the most common barcode on retail and wholesale products in North America. A UPC-A has 12 digits. A UPC-E is a compressed 6-digit version for small packaging. In a warehouse, the UPC tells the system what the product is, not where it lives. Scanning a UPC during receiving matches the item to a buy order line. It does not tell the system which bin to put it in.

EAN and GTIN

EAN stands for European Article Number, though it is used worldwide. EAN-13 is the 13-digit global version of UPC-A. Distributors receiving international goods will see EAN on inbound labels. Most modern scanners read both UPC and EAN without any setting change, so the practical difference is the digit count.

GTIN: The Umbrella Term for Product Codes

GTIN stands for Global Trade Item Number. It is an umbrella term that covers UPC, EAN, and several other formats. A GTIN can be 8, 12, 13, or 14 digits depending on the standard used. Large retail buyers often need suppliers to provide a GTIN for each product they sell. The key difference between a UPC and a GTIN is scope: a UPC is one specific format, while a GTIN is the category that includes all of them.

Inline FAQ: What is the difference between a UPC and a GTIN? A UPC is a 12-digit product code used mainly in North America. A GTIN is the broader term that includes UPC, EAN, and other formats. Every UPC is a GTIN, but not every GTIN is a UPC.

SKU, LOT, and SN: Internal Tracking Abbreviations

SKU, LOT, and SN are abbreviations that come from inside the business, not from a standards body. They track variants, batches, and individual units.

SKU stands for Stock Keeping Unit. A SKU is created by the business itself. It lets a distributor track variants like size, color, or pack count as separate items. SKU numbers are often encoded into barcodes on bin labels and pick tickets. A SKU is different from a barcode: the SKU is the identifier, and the barcode is the printed symbol that carries it.

LOT and SN: Batch and Unit Tracking

LOT refers to a lot number, which groups items made or received in the same batch. SN or S/N stands for serial number, a unique code for a single unit. Food, pharmaceutical, and electronics distributors rely on LOT and SN tracking for recalls and warranty claims. Both are often encoded in a barcode alongside the product GTIN on the same label, so 1 scan captures the product identity and the batch or unit identity at once.

Inline FAQ: What does SKU stand for and how is it different from a barcode? SKU stands for Stock Keeping Unit. A SKU is an internal code your business creates to track a specific product variant. A barcode is the printed symbol that carries the SKU, so the scanner can read it without manual typing.

Barcode Symbologies: Code 39, Code 128, ITF-14, and QR

A barcode symbology is the format, or the visual language, a barcode uses. When software asks which symbology to print, it is asking which format to use.

Code 39 encodes letters and numbers. It is common on internal warehouse labels because it is simple and widely supported. Code 128 encodes more data in less space. It is the standard for shipping labels and GS1-128 applications, which encode multiple data fields in a single barcode. If a scanner fails to read a label, a mismatch between the printed symbology and the scanner's expected format is often the cause.

ITF-14 stands for Interleaved Two of Five, a 14-digit barcode format used on cases and pallets rather than individual items. It encodes a GTIN-14 and is built to stay readable on rough corrugated packaging. Wholesale distributors see ITF-14 on master cartons arriving from suppliers.

What is a QR code used for in a warehouse?

QR stands for Quick Response, and a QR code is a two-dimensional barcode that holds far more data than a standard linear barcode. In warehousing, QR codes appear on bin labels, work orders, and equipment tags. A QR code can store a URL, so scanning one can open a receiving checklist or product page directly on a mobile device. That makes them useful for tasks where a worker needs more than just an identifier.

Inline FAQ: What is the difference between Code 39 and Code 128? Code 39 encodes letters and numbers in a simple format common on internal labels. Code 128 holds more data in less space and is the standard for shipping and GS1 labels. Use Code 128 for any label that needs to leave your building.

GS1, SSCC, and ASN: Shipping and Compliance Abbreviations

GS1, SSCC, and ASN are abbreviations that connect your warehouse to your trading partners. They appear on pallet labels, shipping documents, and vendor compliance requirements.

GS1 is the global organization that sets barcode and data standards. Many abbreviations in this guide, including GTIN and SSCC, come from GS1 specifications. GS1-128 is a barcode standard used on shipping labels that encodes multiple data fields at once, such as GTIN, lot number, and expiry date in a single scan. Understanding that GS1 is a standards body, not a product or a vendor, explains why so many abbreviations trace back to it.

SSCC and ASN: Pallet Identity and Pre-Shipment Notice

SSCC stands for Serial Shipping Container Code. It is an 18-digit number that uniquely identifies a pallet or shipping container. SSCC barcodes appear on pallet labels. Fulfillment centers scan SSCC codes during receiving to match a pallet to an incoming shipment record without counting every item by hand.

ASN stands for Advanced Shipping Notice, an electronic document sent before a shipment arrives. An ASN lists what is on each pallet and includes the SSCC barcodes for each one. The warehouse scans the SSCC on arrival and the system fills in the rest. Many large retail buyers need an ASN as part of their vendor compliance rules. Skipping the ASN means the buyer's receiving dock does manual entry, and they often charge back the cost.

Inline FAQ: What is an SSCC barcode and when is it used? SSCC stands for Serial Shipping Container Code. It is an 18-digit number printed as a barcode on a pallet label. The receiving warehouse scans it to pull up the full contents of that pallet from the ASN, removing the need to count and key in every item.

BIN, PO, and SO: Location and Order Abbreviations

What does a BIN code on a warehouse label mean?

BIN is short for bin location, the physical address of a storage slot in a warehouse. Bin codes are printed as barcodes on shelf labels. A typical bin code encodes aisle, bay, level, and slot in a short alphanumeric string. Scanning a bin barcode instead of typing a location removes the manual entry step that causes most mis-picks. A picker who scans both the item barcode and the bin barcode gives the system 2 confirmation points before the pick is logged.

PO stands for Buy Order. SO stands for Sales Order. Both are printed as barcodes on receiving documents and pick tickets. Scanning a PO barcode during receiving links each item scan to the correct buy order automatically. That keeps records accurate in your inventory or accounting system without rekeying data at the end of the shift.

WMS and IMS: The Software That Reads Every Scan

WMS stands for Warehouse Management System. IMS stands for Inventory Management System. These are the platforms that receive barcode scans and update stock records. A WMS manages location and movement inside a warehouse. An IMS tracks quantities across locations, often including multiple sites or sales channels. Smaller distributors often use an IMS that connects to QuickBooks rather than a full WMS, which keeps costs down while still automating the scan-to-record step.

The Cost Case for Barcode Scanning Software

Consider the labor cost before deciding a WMS is unnecessary. 2 warehouse staff spending 3 hours a day on manual data entry at $22 an hour, the median wage for stock clerks according to the US Bureau of Labor Statistics, adds up to $34,320 a year. A barcode scanning system that cuts that time in half pays for itself quickly. The IRS also needs businesses to value inventory at the start and end of each tax year: "To figure taxable income, you must value your inventory at the beginning and end of each tax year," per IRS Publication 538. Accurate scanning makes that count faster and more reliable.

Building a Barcode System That Uses These Abbreviations Correctly

Start by listing which barcode abbreviations your suppliers, customers, and carriers need. Map each one to a field in your inventory software. Choose Code 128 as your default symbology: it covers most warehouse use cases and is readable by every modern scanner.

The NIST Manufacturing Extension Partnership recommends aligning your labeling process to the standards your trading partners already use, which reduces compliance friction without requiring a full system overhaul. A custom-built inventory system can be designed around the label formats and abbreviations your operation already uses, including your existing QuickBooks setup, rather than forcing your team to change how they work to fit a new platform.

Closing the Knowledge Gap on the Warehouse Floor

If your scanner screens show abbreviations your team cannot explain, that gap is a risk. Every abbreviation in this guide connects to a real task: receiving, picking, shipping, or counting. When staff know what each one means, they catch label errors before those errors become wrong shipments or inventory discrepancies.

A barcode inventory management system overview can help you see how all these pieces connect in a single workflow. If you want to explore how barcode scanning integrates with QuickBooks, or need a warehouse bin location labeling guide built around your current setup, the right starting point is a review of the abbreviations and label formats your operation already uses, and then building from there.
