Punctuation - Subfields do not end with a mark of punctuation unless an abbreviation, initial/letter, or other data that ends with a mark of punctuation is present.
Style for Recording Address Information - In subfield $c standard abbreviations for states and provinces are preferred, such as the two-character U.S. Postal Service abbreviations for the American states and the Canada Post abbreviations for the Canadian provinces. In subfield $d, the full name of the country is preferred, with exceptions for widely recognized abbreviations, such as U.S. for the United States of America.
Input Order of Telephone Numbers - If the address has a regular telephone number and a contact person at that address has a different telephone number, the telephone number associated with the address follows the address information (subfields $a-$e); the telephone number associated with an attention or contact person follows the name of the person with whom it is associated.

If the telephone numbers of the address and the person are the same, the telephone number follows the address information.
Style for Recording Telephone, Fax, etc. Numbers - In field 270, periods, spaces, and parentheses used to divide the portions of a number are replaced with hyphens. The numbers recorded in subfields $j, $k, $l, and $n are recorded as follows:

Exchange/line number portion often includes internal separators which are replaced by hyphens. If an extension is also given, it is appended to the telephone number preceded by a space and " x".
