Номер почтового ящика может быть меньше или больше четырех цифр. Для почтовых ящиков, как правило, каждый ящик имеет свой собственный почтовый индекс + 4.
Последние четыре цифры часто являются одной из следующих:
1. Ноль плюс последние три цифры номера ящика (eg. PO BOX 1001, Los Angeles CA 90001-0001).
2. Последние четыре цифры номера ящика (eg. PO BOX 9991, Twin Peaks CA 92391-9991).
3. Если номер ящика меньше четырех цифр, то перед номером ящика добавляется достаточно нулей, чтобы получить четырехзначное число.(eg. PO BOX 1, Shreveport LA 71161-0001).
Однако единого правила нет, почтовый индекс плюс четыре используется только для справки, а индекс ZIP + 4 нужно искать индивидуально для каждого поля на официальном веб-сайте USPS.
