# barcodenumber — Python module to validate Product codes (EAN, EAN13, ISBN,...)

License: copyleft · Maintenance: abandoned · Downloads: 447.3K/mo

## What it is and what it does

barcodenumber is a validation library for product identification codes. It wraps python-stdnum to provide a simple interface for checking the validity of barcodes and product identifiers across multiple standards—EAN, GTIN, ISBN, UPC, CODE39, GS1, and others. You pass a code type and a string to its check_code function, and it returns True or False.

The package is straightforward to use but carries significant risk: it has been abandoned since 2019-11-06 with no maintenance, no updates for modern Python versions, and no bug fixes. The classifiers claim support only through Python 3.8, and actual compatibility with later versions is unknown. The GPL-3 copyleft license also restricts use in proprietary or differently licensed projects.

Use it for:

- Validate EAN-13 or EAN-8 codes in e-commerce product databases.
- Check ISBN validity when processing book metadata or library systems.
- Verify GTIN-14 codes in supply chain or inventory management applications.
- Validate UPC codes in retail point-of-sale systems.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Validates product codes across multiple barcode and ISBN standards including EAN, GTIN, ISBN, UPC, and others using a simple check function.

No, unless you are maintaining legacy code already using it. The package is abandoned with no recent maintenance, unverified compatibility with modern Python versions, and a copyleft GPL-3 license that may conflict with your project. For new projects, use an actively maintained barcode validation library instead.

## Install

pip install barcodenumber
uv add barcodenumber
poetry add barcodenumber

## Installing barcodenumber

Before you install: Low install friction with a single runtime dependency (python-stdnum). However, the package is abandoned—last release was 2019-11-06, over 2473 days ago—so expect no maintenance, bug fixes, or compatibility updates.

License in practice: Licensed under GPL-3 (copyleft). Any derivative work or distribution must also be GPL-3 licensed, which may conflict with proprietary projects or other license requirements.

Quickstart:

pip install barcodenumber

import barcodenumber
barcodenumber.check_code('ean13', '9788478290222')

Package is abandoned since 2019-11-06 with only Python 2.7 and 3.3–3.8 listed in classifiers; compatibility with later versions is unverified.

Verify before relying:

- Whether the package actually works on Python versions after 3.8 despite being abandoned.
- Current maintenance status of the python-stdnum dependency and whether it remains actively supported.
