Please note, that it's impossible to directly check the country where your Google Play account is registered. Google doesn't provide this information in the account settings.
However, you can find indirect signs indicating your account's country:
Google Play interface language: If you haven't changed the language manually, then Google Play is most likely using the language set for your country.
Available apps and games: Some apps and games are available only in certain countries. If you see apps intended for a specific country, it might be a sign that your account is registered there.
Payment methods: Available payment methods on Google Play may vary depending on the country.
Address in Google Pay: If you use Google Pay, check the address specified in the settings. It might be the address you used when registering the account.
Important: Information obtained through these methods is not a 100% confirmation of the country where your Google Play account is registered.
