On this page, you can find a list of all zip codes in area code 423. What is a ZIP Code? A ZIP code is a term used to describe the postal code system in the United States. ZIP is the abbreviation of Zonal Improvement plan.
The ZIP code was created in 1963 as a measure to increase mail sorting efficiency. The standard ZIP code notation used by the United States Postal service uses five digits to identify a delivery area. The first three digits refer to a sectional center facility (or SCF), which is a network of super post offices. The last two numbers designate the specific post office within an SCF’s territory. Through a ZIP code, one can identify the location now. If you’re looking for contact information in the USA, it’s helpful to know the zip codes.
