EAN-8 Check Digit Calculator
Calculate or verify an EAN-8 check digit from pasted compact product-code digits locally in your browser.
EAN-8 uses 7 data digits plus one check digit for compact product-code examples. Spaces and hyphens are removed locally.
EAN-8 checksum workflow tips
Use this calculator for compact EAN-8 examples, barcode fixture notes, product-data QA, and import-template checks. It validates the checksum only and does not confirm ownership or live catalog data.
Generate the barcode next
After calculating the check digit, use EAN-8 Barcode Generator to create a browser-local SVG preview from the completed compact value.

Use EAN-13 Check Digit Calculator, UPC-A Check Digit Calculator, or ISBN-13 Check Digit Calculator for related checksum workflows.
Limitations
A valid check digit only confirms numeric structure. It does not prove that a product, GS1 prefix, brand, price, or catalog record exists.
What this tool does
The EAN-8 Check Digit Calculator removes spaces and hyphens, calculates the eighth digit from 7 base digits, or verifies the final digit when you paste a full 8-digit EAN-8 example. It is useful for compact barcode examples, product-data QA notes, fixture documentation, and browser-local checksum checks.
Common use cases
Calculate or verify an EAN-8 check digit from pasted compact product-code digits locally without uploading, storing, or looking up catalog records.
Use EAN-8 Check Digit Calculator when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Enter 7 EAN-8 base digits to calculate the final check digit, or paste a full 8-digit EAN-8 to verify it.
- Review the normalized digits, calculated check digit, and full EAN-8 value.
- Copy the result for documentation, compact-code mock data, QA notes, or spreadsheet cleanup.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
EAN-8 check digit calculation runs locally in your browser. ClearUtils does not upload, store, fetch, look up, or log product-code input.
FAQ
Can this calculate an EAN-8 check digit?
Yes. Enter 7 digits and the calculator adds the eighth check digit using the standard EAN/GTIN weighting formula.
Does this confirm real product data?
No. It validates the numeric check digit only and does not query GS1 prefixes, product databases, prices, or ownership records.
Is my EAN-8 input uploaded?
No. EAN-8 check digit calculation runs locally in your browser and does not upload, store, fetch, or log input.
