Deep-Dive: How GS1-128 Encodes Data

GS1-128 (formerly known as UCC/EAN-128) is a specialized application of the Code 128 symbology governed by GS1 General Specifications. While standard Code 128 can encode arbitrary raw text, GS1-128 is strictly structured using standardized GS1 Application Identifiers (AIs). It enables supply chain partners to communicate complex logistics data—such as pallet Serial Shipping Container Codes (SSCC-18), batch numbers, production dates, expiry dates, net weights, and purchase order numbers—in a universally machine-readable format.

⚙️ Application Identifiers (AIs) & FNC1 Flag Character

The defining characteristic of GS1-128 is its structured data syntax:

›Function 1 (FNC1) Character: A mandatory invisible flag placed immediately after the start character that instructs the scanner that the following data adheres strictly to GS1 Application Identifier standards.
›Application Identifiers (AIs): Two-, three-, or four-digit prefixes enclosed in parentheses in human-readable text that define the meaning and format of following data.
›Common AIs: (00) SSCC-18 Pallet Identifier, (01) GTIN Trade Item Number, (10) Batch/Lot Number, (15) Best Before Date, (17) Expiration Date, (310x) Net Weight in Kilograms, (400) Customer PO Number.
›Variable Length Separators: When combining variable-length data fields, an FNC1 character is inserted between elements to signal the end of one field and the start of the next AI.

🖨️ Production & Printing Best Practices

✔Parentheses around Application Identifiers (e.g. "(01)") are strictly for human-readable presentation and must NOT be encoded into the barcode bars themselves.
✔Keep overall barcode length under 48 data characters (including AIs) and maximum physical length under 165 mm (6.5 inches) including quiet zones to fit standard shipping labels.
✔For pallet logistics labels (SSCC), print at an X-dimension between 0.495 mm and 1.016 mm and place the label on two adjacent sides of the pallet.

Perguntas Frequentes (FAQ)

What is a GS1 Application Identifier (AI)?

Application Identifiers (AIs) are 2, 3, or 4-digit prefixes in parentheses that define the meaning and format of the data that follows. For example, (01) is GTIN, (10) is Batch Number, and (17) is Expiration Date.
