• 加4?

  4-digits that are used to identify a geographic segment within the 5-digit delivery area, such as a city block or a group of apartments or an individual high-volume receiver of mail, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. This code is the low end of the range of +4 Codes that pertain to this ZIP Code. ZIP+4 Codes associated with nondelivery areas are composed of valid ZIP sector numbers and "ND" for the ZIP segment number, for example 12345-12ND. Non-deliverable areas are areas to which the USPS does not deliver mail, such as vacant lots and land that borders railroad tracks. Mailers should not match an address identified as a nondelivery area. If you absolutely must have numeric characters in the Plus4Code column, you may treat "ND" values as "00" (zero zero).

• 街道?

  The official name of a street as assigned by a local governing authority. The Street Name column contains only the street name and does not include directionals (EAST, WEST, etc.) or suffixes (ST, DR, BLVD, etc.). This element may also contain literals, such as PO BOX, GENERAL DELIVERY, USS, PSC, or UNIT. Numeric street names that have numeric components that are four characters (or less) in length at are justified such that the low-order digit of the number is positioned in the fourth position of the street name column. This shift is made so that the numeric street names appear in numeric sequence.

  [+]更多地址示例

  邮政信箱号码可以小于或大于四位数。对于邮政信箱来说，一般规则是每个信箱都有自己的ZIP+4邮编。
  最后四位数字通常表示方法如下：
  1. 零加上邮箱号码后三位数字构成 (eg. PO BOX 1001, Los Angeles CA 90001-0001).
  2. 邮箱号码后四位 (eg. PO BOX 9991, Twin Peaks CA 92391-9991).
  3. 如果邮箱号码数少于四位数，则在邮箱号码前面加上零形成四位数(eg. PO BOX 1, Shreveport LA 71161-0001).
  但没有统一的规则，邮政编码5+4仅供参考，折叠地址中5+4邮编需要去USPS官网查看确认。

• 一般来说，九位邮政编码会分配给一个或多个邮政信箱，具体取决于邮箱的邮件量。如果将一个邮政编码分配给多个邮政信箱，则这些邮箱很可能位于同一个区域，因此邮政信箱号码的奇数或偶数没有任何区别。
• 如果你想使用邮政信箱地址进行邮寄，也许需要先知道如何租用邮政信箱。
