We have an odd scenario where we need to support vCard 2.1, however, we've discovered a formatting issue with it on newer phones. In cases where we specify format 2.1, the label for the address shows as CHARSET. Upon further investigation, I discovered you format the ADR field exactly the same for 2.1 as you do for 3.0. This is making the phones pickup the label as the defined charset and not the type as specified or ignoring the field all together.
It took some digging, but I did find the original 2.1 specification with an example:
Delivery Addressing Properties
Delivery Address
This property specifies a structured representation of the physical delivery address for the vCard object. The property is made up of components that are based on the X.500 Post Office Box attribute, the X.520 Street Address geographical attribute, the X.520 Locality Name geographical attribute, the X.520 State or Province Name geographical attribute, the X.520 Postal Code attribute, and the X.520 Country Name geographical attribute.
This property is identified by the property name ADR. The property value consists of components of the address specified as positional fields separated by the Field Delimiter character (ASCII decimal 59). The property value is a concatenation of the Post Office Address (first field) Extended Address (second field), Street (third field), Locality (fourth field), Region (fifth field), Postal Code (six field), and Country (seventh field) strings. An example of this property follows:
ADR;DOM;HOME:P.O. Box 101;Suite 101;123 Main Street;Any Town;CA;91921-1234;
Support for this property is optional for vCard Writers conforming to this specification.
Delivery Address Type
This property parameter specifies the sub-types of physical delivery that is associated with the delivery address. For example, the label may need to be differentiated for Home, Work, Parcel, Postal, Domestic, and International physical delivery. One or more sub-types can be specified for a given delivery address.
The property parameter can have one or more of the following values:
Description
Property Parameter Value
TYPE=
Indicates a domestic address
DOM
Indicates an international address (Default)
INTL
Indicates a postal delivery address (Default)
POSTAL
Indicates a parcel delivery address (Default)
PARCEL
Indicates a home delivery address
HOME
Indicates a work delivery address (Default)
WORK
While it does say that you can specify TYPE=, modern Android and iPhones do not seem to pick up on this. The few examples I've found across the internet have also favored the type as the second field for ADR and omits the TYPE=
