What is AutoNumeric?

AutoNumeric is a standalone Javascript library that provides live as-you-type formatting for international numbers and currencies.


AutoNumeric main features are:

  • Easy to use and configure
  • Very high configurability (more than 40 options available)
  • User experience oriented ; using autoNumeric just feels right and natural, specially with the function chaining feature
  • Supports most international numeric formats and currencies
    (If the one you use is not supported yet, open an issue and we'll add it as soon as possible!)
  • The mobile Android Chrome browser is partially supported

...and much more.

All in all, AutoNumeric supports most international numeric formats and currencies including those used in Europe, Asia, and North and South America.


The documentation previously shown in that readme has now been moved to a specific web page where it's much more user-friendly; you can check it out on


For checking the official AutoNumeric website, you can take a look at On this website you'll find additional tools for instance to generate your options configuration.

AutoNumeric versions

AutoNumeric provides 2 branches, master and next.

The very, very stable version is on the master branch (currently this is version 4.6.*).

The next branch contains all the new features and fixes, and is considered 'stable' too.

Do note that the next branch can see changes in the API (check the semver), but is always fully tested for regressions.
It's safe to use on production servers since it's always thoroughly tested and should not contain any bugs (that we know of).


AutoNumeric is an MIT-licensed open source project, and its authors are credited in AUTHORS.


AutoNumeric is created using the JetBrains IDE, which kindly provide access to its tools to the developers.
If you feel AutoNumeric is useful to you, please consider supporting the project.
