GS1 Global Trade Item Numbers (GTIN) & EAN Architecture
The European Article Number (EAN-13), formally governed under the international GS1 standard as GTIN-13, is the universal retail barcode identifier across Europe, Asia, Latin America, and Australia. EAN barcodes facilitate automated point-of-sale inventory depletion, supply chain traceability, and automated warehouse receiving.
Country Prefix & Manufacturer Code
The first 2–3 digits indicate the GS1 national member organization where the company prefix was registered (e.g., 00–13 for US/Canada, 50 for the UK, 400–440 for Germany). The subsequent digits represent the individual manufacturer identification and specific item reference.
Modulo-10 Check Digit Calculation
The 13th digit is mathematically derived from the preceding 12 digits using an alternating weighting formula: odd-indexed positions are multiplied by 1 and even-indexed positions by 3. Our engine automatically solves the modulo-10 complement to ensure full compliance with GS1 scanner validation.
Generador de códigos de barras EAN Preguntas frecuentes
¿Qué es EAN-13?
EAN-13 es un estándar de código de barras de 13 dígitos usado en productos minoristas en todo el mundo. El último dígito es un dígito de control calculado a partir de los primeros 12.
¿Cuál es la diferencia entre EAN-13 y EAN-8?
EAN-13 es el formato estándar de 13 dígitos. EAN-8 es una versión compacta de 8 dígitos usada en paquetes pequeños donde un EAN-13 completo no cabría.
¿Cómo se calcula el dígito de control EAN-13?
Los dígitos en posiciones impares se multiplican por 1, los dígitos en posiciones pares por 3. Suma todos los resultados y resta el último dígito del total de 10.
¿Puedo validar un código de barras EAN-13 existente?
Sí. Desactiva «Calcular dígito de control automáticamente» e introduce los 13 dígitos. La herramienta valida tu dígito de control y te indica el correcto si está mal.
1D Barcode Symbologies & Scanning Standards
Linear 1D barcodes encode alphanumeric data using alternating parallel lines and spaces with standardized width ratios. Choosing the appropriate symbology, such as Code 128 for variable-length logistics labels, EAN-13 for global retail products, or UPC-A for North American point-of-sale systems, ensures reliable optical recognition across laser scanners, CCD readers, and camera-based mobile apps.
Quiet Zones & Contrast
Maintain a solid unprinted margin (the quiet zone) of at least 10 times the narrowest bar width on both ends. Ensure high optical contrast-dark bars on a clean white background-to prevent scanner read failures under warehouse and retail lighting.
Vector Print & Privacy Security
Export your finished code in SVG vector format for crisp, infinite scalability on large signage, product packaging, and business cards without pixelation. All generation and camera decoding executes 100% locally in your browser memory-no private credentials, URLs, or scans are ever uploaded to a server.
Additional Technical FAQs
What is the minimum recommended print size for reliable scanning?
For standard smartphone camera scanning at close range (0.3–0.5 meters), print QR codes at a minimum size of 2 x 2 cm (0.8 x 0.8 inches). For posters and billboards, use a 10:1 distance-to-size ratio (e.g., a code scanned from 2 meters away should be at least 20 cm wide).
Are generated codes permanent, and do they ever expire?
All codes generated on BeYourTools are static and permanent. The encoded data (such as your URL, text, or barcode number) is directly baked into the graphical modules with zero server redirection, meaning they will function forever without expiration.
