Create standard barcodes with Python. No external modules needed. (optional Pillow support included).

Project description

CI status Build coverage documentation version on pypi licence

This library provides a simple way to create barcodes using only the Python standard lib. The barcodes are created as SVG objects.


Full documentation is published at

  • Works on Python 3.5 to 3.8

  • No visualiser (just use your browser)

  • Generate barcodes as SVG files.

  • Generate barcodes as images (png, jpeg, etc). Requires Pillow.


The best way is to use pip: pip install python-barcode. Don’t forget to add this to our app’s dependencies.

If you’ll be exporting to images (eg: not just SVG), you’ll need additional optional dependencies, so run: pip install python-barcode[images].

Provided Barcodes

  • EAN-8

  • EAN-13

  • EAN-14

  • UPC-A

  • JAN

  • ISBN-10

  • ISBN-13

  • ISSN

  • Code 39

  • Code 128

  • PZN

PRs for other code formats are welcome!



from barcode import EAN13
from barcode.writer import ImageWriter

# print to a file-like object:
rv = BytesIO()
EAN13(str(100000902922), writer=ImageWriter()).write(rv)

# or sure, to an actual file:
with open('somefile.jpeg', 'wb') as f:
    EAN13('100000011111', writer=ImageWriter()).write(f)


>>> import barcode
['code39', 'code128', 'ean', 'ean13', 'ean8', 'gs1', 'gtin',
 'isbn', 'isbn10', 'isbn13', 'issn', 'jan', 'pzn', 'upc', 'upca']
>>> EAN = barcode.get_barcode_class('ean13')
>>> EAN
<class 'barcode.ean.EuropeanArticleNumber13'>
>>> ean = EAN('5901234123457')
>>> ean
<barcode.ean.EuropeanArticleNumber13 object at 0x00BE98F0>
>>> fullname ='ean13_barcode')
>>> fullname
# Example with PNG
>>> from barcode.writer import ImageWriter
>>> ean = EAN('5901234123457', writer=ImageWriter())
>>> fullname ='ean13_barcode')
# New in v0.4.2
>>> from io import BytesIO
>>> fp = BytesIO()
>>> ean.write(fp)
# or
>>> f = open('/my/new/file', 'wb')
>>> ean.write(f) # Pillow (ImageWriter) produces RAW format here
>>> from barcode import generate
>>> name = generate('EAN13', '5901234123457', output='barcode_svg')
>>> name
# with file like object
>>> fp = BytesIO()
>>> generate('EAN13', '5901234123457', writer=ImageWriter(), output=fp)

Now open ean13_barcode.[svg|png] in a graphic app or simply in your browser and see the created barcode. That’s it.


`$ python-barcode create "123456789000" outfile -b ean --text "text to appear under barcode" `
New barcode saved as outfile.svg.

# The following will not work if Pillow is not installed (Pillow is required for exporting to images instead of SVG).
$ python-barcode create -t png "My Text" outfile
New barcode saved as outfile.png.

Try `python-barcode -h` for help.



  • Removed writer_options from barcode.get. This parameter was not used.

  • Add a with_doctype flag to SVGWriter. Set this to false to avoid including a DOCTYPE in the resulting SVG.


  • Added basic support for multiline text.

  • Dropped lots of older compat-only code and other cleanups.

  • Fixed a bug in the API when combining certain barcodes and writers.

  • Published documentation again and updated all project references.

  • Fix python_barcode.get mixups between options as writer_options. Previously, some writer/barcode combinations worked fine, while others failed. Now all work consistently.

  • The cli tool has been fixed and should now work as expected again.


  • Added support for GS1-128.


  • Officially support Python 3.7

  • Refer to Pillow in the docs, rather than PIL.


  • Removed buggy Barcode.raw attribute.

  • Various CLI errors ironed out.

  • Make the default value for writer_options` consistent across writers.


  • Fix pushing of releases to GitHub.


  • Fix crashes when attempting to use the CLI app.

  • Properly include version numbers in SVG comments.


  • Improve README rendering, and point to this fork’s location (the outdated README on PyPI was causing some confusion).


  • First release under the name python-barcode.

Previous Changelog

This project is a fork of pyBarcode, which, apparently, is no longer maintained. v0.8.0 is our first release, and is the latest master from that parent project.


  • Code 128 added.

  • Data for charsets and bars moved to subpackage barcode.charsets.

  • Merged in some improvements.


  • Fixed some issues with fontsize and fontalignment.

  • Added Python 3 support. It’s not well tested yet, but the tests run without errors with Python 3.3. Commandline script added.


  • Changed save and write methods to take the options as a dict not as keyword arguments (fix this in your code). Added option to left align the text under the barcode. Fixed bug with EAN13 generation.


  • Added new generate function to do all generation in one step.

  • Moved writer from a subpackage to a module (this breaks some existing code). UPC is now rendered as real UPC, not as EAN13 with the leading “0”.


  • Fixed bug in new write method (related to PIL) and updated docs.


  • Added write method to support file like objects as target.


  • Bugfix release. Removed redundancy in input validation.

  • EAN8 was broken. It now works as expected.


  • Removed **options from writers __init__ method. These options never had effect. They were always overwritten by default_options.

  • New config option available: text_distance (the distance between barcode and text).


  • Basic documentation included. The barcode object now has a new attribute called raw to have the rendered output without saving to disk.


  • Support for rendering barcodes as images is implemented. PIL is required to use it.


  • Compression for SVG output now works.


  • Writer API has changed for simple adding new (own) writers.

  • SVG output is now generated with xml.dom module instead of stringformatting (makes it more robust).


  • API of render changed. Now render takes keyword arguments instead of a dict.


  • More tests added.


  • First release.
