12 uia state postal abbreviation
UIA State Postal Abbreviation (IMT-UI-STATE)
The UI-address state field is the 2-byte postal abbreviation of the State to which mailings are to be sent, located at positions 386 and 387. Valid 2-character postal abbreviations should be placed in this field if a U-I address is present. In addition to the values described for IMT-PL-STATE earlier, a value of "CN" may also be used for mailing addresses in Canadian provinces. The province of such an address needs to be incorporated into the IMT-UI-CITY field. Military APO and FPO codes ("AE", "AP", etc.) can also appear here. Foreign addresses should show a "ZZ" state code. These should also identify both the city and country in the IMT-UI-CITY field. If the U-I tax mailing address is unknown or unchanged, this field should be low-values.
