Use these identifiers accurately
The two-letter code GU is the compact ISO identifier used in addresses, locale selectors, and many data feeds. The dialing prefix +1671 belongs at the start of an international phone number. Time zone names such as Pacific/Guam should be preferred over a fixed UTC offset because they carry daylight-saving rules.
