The languageCode read-only property of the PaymentAddress interface returns a string containing the language code for the address according to RFC 5646: Tags for Identifying Languages (also known as BCP 47).

This is used while localizing the display of the address, allowing the determination of the field separators and the order of fields when formatting the address.


var paymentLanguageCode = PaymentAddress.languageCode;


A string providing the RFC 5646: Tags for Identifying Languages (also known as BCP 47) format language code indicating the language the address was written in, such as "en-US", "pt-BR", or "ja-JP".
