burhan/django-localflavor

Django-localflavor is a package that adds country-specific validation and form tools to Django web applications. Instead of building your own checks for postal codes, phone numbers, or national ID formats, you can use pre-built helpers that understand the rules for dozens of countries. For example, if you're building a site that serves users in Canada, you can use a postal code field that knows the Canadian format and validates accordingly. The package originated as part of Django's core framework, but was spun out into a separate project to keep Django itself lean. Now it lives independently, which means it can be updated on its own schedule without waiting for Django releases. You install it separately via pip and then import country-specific form fields and validators into your Django project. Each country has its own module with relevant helpers. A developer building a checkout form for a Brazilian e-commerce site, for instance, could use pre-made fields for validating Brazilian phone numbers or CPF (national ID) numbers. Similarly, someone running a UK-focused service could leverage postal code validation tuned to how Royal Mail actually formats addresses. This saves time compared to writing regex patterns or validation logic from scratch, and the code has been tested across real-world data. The project maintains compatibility with multiple Django versions, so whether you're on an older or newer release, you can usually find a version that works. The full list of supported countries and their available fields is documented online, so you can check upfront whether the localflavor for your target region exists. If it doesn't, you're free to contribute one, the project is open source and welcomes additions.
