# EAN-8 Barcode Validator Validate 8-digit EAN-8 / GTIN-8 product barcodes with check-digit verification, GS1 country prefix and packaging breakdown. > Canonical page: https://elysiatools.com/en/tools/ean8-validator - **Category:** Validation - **Keywords:** ean-8, ean8, gtin-8, barcode, product, validator, check digit, gs1 ## Overview The EAN-8 Barcode Validator is a dedicated utility designed to verify 8-digit EAN-8 and GTIN-8 product barcodes. It performs instant check-digit verification, identifies the GS1 country prefix, and breaks down packaging details while tolerating common formatting variations like spaces, dashes, and add-on codes. ## Inputs - **EAN-8 Barcode** (text): 8-digit EAN-8 / GTIN-8 number. Spaces, dashes and a 2/5-digit add-on are tolerated. ## When to use - When you need to verify if an 8-digit EAN-8 barcode has a mathematically correct check digit. - When you want to identify the GS1 country of origin prefix from a GTIN-8 product code. - When troubleshooting scanning issues on small retail packaging by checking barcode formatting and add-on digits. ## How it works - Enter the 8-digit EAN-8 or GTIN-8 barcode into the input field, including any spaces, dashes, or 2/5-digit add-ons. - The validator strips non-numeric formatting characters and isolates the core 8-digit sequence. - The tool calculates the expected check digit using the GS1 modulo-10 algorithm and compares it to the final digit. - The validator outputs the validation status, identifies the GS1 country prefix, and details the packaging structure. ## Use cases - Retail inventory managers verifying barcode lists before printing labels for small-format products. - Quality assurance teams checking the validity of GTIN-8 codes received from suppliers. - E-commerce sellers validating product identifiers before listing items on online marketplaces. ## Frequently asked questions ### What is an EAN-8 barcode? It is an 8-digit barcode format used globally on small retail products where a standard EAN-13 barcode would be too large. ### Does this validator support spaces and dashes in the input? Yes, the validator automatically ignores spaces, dashes, and handles optional 2-digit or 5-digit add-on codes. ### How is the EAN-8 check digit calculated? It uses a modulo-10 algorithm with alternating weights of 3 and 1 applied to the first 7 digits. ### Can this tool validate EAN-13 barcodes? No, this tool is specifically designed for 8-digit EAN-8 and GTIN-8 barcodes. ### What does the GS1 country prefix indicate? It identifies the GS1 member organization where the manufacturer registered the barcode, which often corresponds to the country of origin. ## Related tools - [UPC/EAN Barcode Validator](https://elysiatools.com/en/tools/upc-ean-validator): Validate GTIN-12 (UPC), GTIN-13 (EAN), GTIN-8, and GTIN-14 product barcodes with check digit verification - [EU VAT Validator](https://elysiatools.com/en/tools/eu-vat-validator): Validate European Union Value Added Tax (VAT) numbers from all EU member states - [CSV Malformed Row Surgeon](https://elysiatools.com/en/tools/csv-malformed-row-surgeon): Surgically repair malformed CSV rows one at a time: unescaped (stray) quotes, mixed delimiters (tab/semicolon/comma in the same file), BOM-prefixed headers, CRLF/CR line endings and trailing empty lines.
