| The United States Post Office has a publication, number 28, that specifies everything you care to know about addresses. An address line, which could be a P.O. Box number, is recommended to be 30 bytes although 64 is considered optimum by the Post Office. If I recall correctly -- and I'm not sure I do -- 16 bytes is the absolute minimum you're allowed to use to meet U.S.P.S. standards. |
