What are the 4 digits after ZIP code?
The first part is the first five digits of the zip code which indicates the destination post office or delivery area. The last 4 digits of the nine-digit ZIP Code represents a specific delivery route within that overall delivery area. All 9 digits of a full zip code assist the USPS in effectively sorting the mail.
Do all addresses have a 9 digit zip code?
The last four digits are not specific to a city but to a street address or Post Office Box. This is what an address looks like with the ZIP +4 Code: The first five digits identify the area of the country and the delivery office to which the mail is directed. ZIP Codes in the far west start with a nine (9).
