+9 is not a ZIP Code. ZIP Codes are postal codes used in the USA. They are uniformly 5 digits, with a 4-digit extension.
There are telephone country codes that begin with +9, but you need one or two more digits.
The whole point of the 9-digit ZIP Code is that it is more specific than a 5-digit ZIP Code. Thus, with only a very few special exceptions, each 5-digit ZIP Code has hundreds or even thousands of different 9-digit ZIP Codes.
There are 9 digits in a ZIP+4 code, which gives you one billion possible codes. Obviously, most of those are not used, but each ZIP+4 code serves at most one side of one block of one street, so there are millions of them.
The ZIP code for the White House is 20500.
The Zip Code for Milltown, New Jersey is 08850.
9 digits in a zip code
The United States ZIP code is five digits. The ZIP+4 code is nine numbers. 9 numbers helps get the mail to you faster because the 5-digit ZIP code identifies a delivery zone; the extra 4 digits in a ZIP+4 pinpoints the region within the zone down to the city block. Also, there can be several cities associated with one ZIP code because they are all within the one delivery zone. Take area code 7836: It encompasses 5 cities in Texas. Another example is 62812: it encompasses 6 cities!
If only I knew
You will need to provide a specific address. A five-digit ZIP code typically contains hundreds or thousands of ZIP+4 codes, as that is the whole point of ZIP+4 codes.
