2.8.49.4 Email address (ST)

Internationalization note: To make this data type interoperate with CEN’s Telecommunication data attribute group, we allow use of the second component for email addresses. The presence of an email address is specified by the addition of the value NET to the Phone Use Code table, and the type of internet address is specified with the values Internet and X.400 to the Phone Equipment Type table. When used for an Internet address, the first component of the XTN data type will be null. If the @-sign is being used as a subcomponent delimiter, the HL7 subcomponent escape sequence may be used when encoding an Internet address (see Section 2.9.1., "Formatting codes").

Note: Components five through nine reiterate the basic function of the first component in a delimited form that allows the expression of both local and international telephone numbers. In Version 2.3, the recommended form for the telephone number is to use the delimited form rather than the unstructured form supported by the first component (which is left in for backward compatibility only).
