1. Retail & Consumer Goods

Notes

• EAN-13 is the global default. Every product sold in international retail must carry one.
• UPC-A is effectively a subset of EAN-13 — all UPC-A scanners read EAN-13.
• GS1 DataBar is increasingly replacing EAN-13 for fresh food because it can encode expiry date and weight alongside the GTIN.
• Quiet zone requirement: minimum 2.5 mm on both sides for all GS1 retail barcodes.

2. Logistics & Shipping

Notes

• Code 128 is the workhorse of global logistics. If you support only one barcode for this industry, it should be Code 128.
• GS1-128 is Code 128 with GS1 Application Identifiers (AIs) — structured data fields like (00) for SSCC, (10) for lot number, (17) for expiry date.
• ITF-14 is specifically designed to survive low-quality printing on cardboard — wider bars tolerate bleed.
• MaxiCode is a UPS proprietary format. Fixed hexagonal matrix, designed for robotic conveyor scanners at 30+ items/second.

3. Healthcare & Pharmaceutical

Notes

• DataMatrix is mandated by the FDA under 21 CFR Part 830 (UDI regulation) for all medical devices. It must encode at minimum the Device Identifier (DI) and, where applicable, the Production Identifier (PI) — lot, serial, manufacturing date, expiry.
• GS1-128 on drug packaging is required in the US under DSCSA (Drug Supply Chain Security Act) for serialisation and track-and-trace.
• Codabar is a legacy format still found in older lab and hospital systems. New implementations should use GS1-128 or DataMatrix instead.
• Minimum module size for DataMatrix on medical devices: 0.254 mm (10 mil) per FDA guidance.

4. Manufacturing & Industrial

Notes

• Code 39 remains the standard in US defence procurement (MIL-STD-1189B) and European automotive supply chains (VDA 4902). It requires no check digit, which simplifies implementation.
• DataMatrix for DPM is the go-to for permanently marking machined parts, PCBs, and surgical instruments. Dot-peen, laser, and chemical etching all produce readable DataMatrix marks.
• QR Code error correction levels: L (7%), M (15%), Q (25%), H (30%). Manufacturing environments should use Level M or higher to tolerate surface contamination.
• Aztec Code requires no quiet zone — useful when label real estate is extremely limited.

5. Food & Grocery

Notes

• EAN-13 is the non-negotiable standard for any packaged food sold through retail. A GS1 Company Prefix is required to obtain valid EAN-13 numbers.
• GS1 DataBar Expanded is the preferred barcode for items priced by weight at checkout. It can encode GS1 Application Identifiers alongside the GTIN — critical for deli, bakery, and produce departments.
• GS1 Digital Link QR is the future-facing format. GS1 has set 2027 as the target for retailers to accept it as a replacement for EAN-13. It functions at POS and simultaneously provides a consumer-facing web link.
• EU Regulation 1169/2011 requires allergen information to be clearly declared — some implementations encode this in GS1 DataBar Expanded or GS1 Digital Link.

6. Library & Publishing

Notes

• ISBN-13 is simply EAN-13 with a 978 or 979 prefix. Any EAN-13 scanner reads ISBN barcodes without modification.
• The 978 prefix (Bookland) is used for standard ISBN books. The 979 prefix was introduced to expand capacity and is also used for sheet music (ISMN).
• Code 39 on spine labels is printable on any standard thermal desktop label printer — no special barcode printer required.
• New library system implementations should replace Codabar patron barcodes with Code 39 or Code 128 where possible.

7. Government, Transport & ID

Notes

• PDF417 on driver's licences is standardised by AAMVA (American Association of Motor Vehicle Administrators). It encodes name, address, DOB, licence class, restrictions, endorsements, and issue/expiry dates.
• Aztec Code is mandated by IATA for airline boarding passes (BCBP standard) and widely used in European rail. Its advantage is zero quiet zone requirement — critical for narrow thermal-printed tickets.
• Intelligent Mail barcode (IMb) replaced POSTNET and PLANET in 2013. It encodes a 65-bar sequence containing the Routing Code (ZIP+4) and a 20-digit Barcode ID for tray and sortation tracking.
• Royal Mail 4-State uses four bar heights (ascender, descender, full, tracker) to encode each character. The KIX code variant is used by PostNL in the Netherlands.

8. Finance & Retail Payments

Notes

• EMVCo QR is the global standard for merchant-presented QR payments. UPI (India), PayNow (Singapore), PromptPay (Thailand), and most Southeast Asian schemes are built on EMVCo QR or country-specific derivatives.
• The QR payment format encodes merchant ID, currency, country, and optionally a pre-filled amount — the payer's app reads and confirms the transaction.
• PDF417 on loyalty cards allows a single barcode to carry enough data for both transaction verification and loyalty point redemption, eliminating the need for a separate card swipe.
