Recently had to fix a similar issue where a zipcode from Florida landed in Spain (https://github.com/olivierlacan/indigene/issues/219).

That's what I get for trying to limit myself to client-side APIs but I'll take your repro and try to address it. Here's the tracking issue if you're interested: https://github.com/olivierlacan/indigene/issues/251

Edit: should be addressed by this change if you'd like to give another try: https://github.com/olivierlacan/indigene/pull/252
