หมายเลขตู้ป ณ . ต้องน้อยกว่าหรือมากกว่าสี่หลัก สำหรับตู้ไปรษณีย์กฎทั่วไปคือแต่ละกล่องจะมีรหัส ZIP + 4 ของตัวเอง
ตัวเลขสี่หลักสุดท้ายมักเป็นตัวเลขใดตัวหนึ่งต่อไปนี้:
1. ศูนย์บวกสามหลักสุดท้ายของหมายเลขกล่อง (eg. PO BOX 1001, Los Angeles CA 90001-0001).
2. สี่หลักสุดท้ายของหมายเลขกล่อง (eg. PO BOX 9991, Twin Peaks CA 92391-9991).
3. หากหมายเลขกล่องน้อยกว่าสี่หลักให้มีเลขศูนย์ที่อยู่ข้างหน้าหมายเลขกล่องมากพอเพื่อสร้างตัวเลขสี่หลัก(eg. PO BOX 1, Shreveport LA 71161-0001).
อย่างไรก็ตามไม่มีกฎที่เหมือนกันรหัสไปรษณีย์บวกสี่ใช้สำหรับการอ้างอิงเท่านั้นต้องค้นหารหัส ZIP + 4 ทีละกล่องในเว็บไซต์ทางการของ USPS
