GoogleMaps API with component filter doesn't return same results when i set the country filter

Question

I need to query google maps to find information about a postal code. I need to know where in the world this postal code can be found. For exemple, if i want information about the postal code 75001, i expect to receive at least these results:

• Addison, TX 75001, USA
• 75001 Paris, France

If i query google maps by specifying the country code, we can cleary see that the postal code exist in the USA and in France:

• https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:75001|country:US&sensor=false will return Addison, TX 75001, USA
• https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:75001|country:FR&sensor=false will return 75001 Paris, France

If i query google maps by omitting the country code, it only return the USA address:

• https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:75001&sensor=false will only return Addison, TX 75001, USA

Why it doesn't return the one from France?

Answer 1

I tried it using different postal code like this 272012, and it give me two locations, one from China and one from Singapore.

https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:272012&sensor=false

And if I specified the country like CN or SG it give me only exact answer.

https://maps.googleapis.com/maps/api/geocode/json?components=postal_code:272012|country:SG&sensor=false

So I don't have any idea what is the problem with that postal code.
