사서함 번호는 4 자리 이하일 수 있습니다. 우체국 상자의 경우 일반적으로 각 상자에는 고유 한 ZIP + 4 코드가 있습니다.
마지막 네 자리는 종종 다음 중 하나입니다.
1. 0과 상자 번호의 마지막 세 자리 (eg. PO BOX 1001, Los Angeles CA 90001-0001).
2. 박스 번호의 마지막 4 자리 (eg. PO BOX 9991, Twin Peaks CA 92391-9991).
3. 상자 번호가 4 자리 미만인 경우 상자 번호 앞에 4 자리 숫자를 생성하기에 충분한 0이 추가됩니다.(eg. PO BOX 1, Shreveport LA 71161-0001).
그러나 통일 된 규칙은 없습니다. 우편 번호 + 4는 참조 용일 뿐이며 ZIP + 4 코드는 USPS 공식 웹 사이트에서 각 상자에 대해 개별적으로 조회해야합니다.
