A ZIP+4 code is a two-letter combination that is used by the United States Postal Service (USPS) to identify a specific address. In addition to a street address, it also includes other information such as the city or county and the address's latitude and longitude coordinates. A ZIP+4 code is also used to identify PO Boxes. USPS has an API that lets you access this data.
If you're concerned about the security of your personal information, you can try using the USPS ZIP+4 code lookup tool. Using this tool, you can search for a ZIP code by address or city. Using a ZIP+4 code search will also reveal any special ZIP codes reserved for PO Boxes. Typically, web searches will list a business's full address, including the ZIP code. But, if you've only found their contact page, you won't be able to see the extra four digits.
When you're looking up a ZIP+4 code, you'll see a number that identifies the designator, the addressee, and the postal address. This code is used to identify the address, as well as any changes. It also has the US eLOT Sequence Number, which specifies the four-digit number used to presort mail. The result code will vary depending on which ZIP+4 code is used.
The five-digit ZIP code is made up of a series of letters, ranging from 0 to 9. In general, these digits point to a particular post office and city, so it is easy to determine the correct ZIP+4 code. This tool will give you an approximate delivery time for your mail. It will also show you the nearest post office. This will save you a lot of time and money.
