IssueTracker

Thank you for posting.

Upon checking, it seems that the provided postal codes show in the result and we could not replicate the issue on our end. Kindly test again and provide additional details on the issue encountered.

Also note that the combination of Component Filtering (postal_code & country) is needed to get better results for the largest portion of all postal codes that exist in Google Maps in each country. Adding the country like CA narrows the context of this query sufficiently to trigger the desired result.

Sample request: https://maps.googleapis.com/maps/api/geocode/json?components=postal_code%3AH2X%200C8%7Ccountry%3ACA&key=YOUR_API_KEY

Result:

formatted_address: "Montreal, QC H2X 0C8, Canada",
