Bhutan
Bhutan, a South Asian kingdom in the Himalayas, is identified internationally by the ISO 3166-1 alpha-2 code BT and the alpha-3 code BTN. To reach Bhutanese phone numbers, international callers use the calling code +975. The country’s official top-level domain is .bt, used for domain registration by businesses and organizations operating within Bhutan. For financial transactions, Bhutan uses two official currencies: the Bhutanese ngultrum (BTN), pegged at par to the Indian rupee, and the Indian rupee (INR) itself, which is also legal tender. In business, logistics, and digital contexts, these identifiers—BT, BTN, +975, .bt, BTN, and INR—are essential for clear, standardized communication.
