Find out the source of all countries with geocodes #423
Description
Question to answer in this research
What trusted source of geo data we could use in the project? Data we need to store are
- country name
- country geocode (e.g. US/UK/FR)
- postal code format
- list of postal codes (since could require frequent updates, it's optional)
Research reason
The research is needed because we are going to handle worldwide postal codes, not the US only.
Ideas to start with
- Django have a great plugin https://github.com/yourlabs/django-cities-light . Probably there is something similar for flask as well.
