need to import without lat and long

You can create a custom post type that NEVER needs addresses:
GD > General > > General tab > Select CPT to disable physical location
https://wpgeodirectory.com/docs/core-general/#physical

Such a CPT can NEVER have addresses or maps.

If you want addresses, lat and lng are required, see https://wpgeodirectory.com/docs/core-export/#mandatory

You can add zeros as lat and lng if you like, but you do need lat and lng. Two zeros will position your listings on the map on the equator on the GMT zero timeline.

These tools help you look up lat and lng in bulk: https://wpgeodirectory.com/docs/core-export/#resources

Thanks

that is correct. Here you find resources of websites providing bulk lat and lon from lists of addresses: https://wpgeodirectory.com/docs/core-export/#resources

personally I think now this is the best: https://www.doogal.co.uk/BatchGeocoding.php

Obviously you’ll need to change from UK to whatever country you want.

Thanks
