What is a ZIP Code?
A ZIP Code (Zone Improvement Plan) is a postal code used by the United States Postal Service (USPS) to ensure accurate and fast mail delivery. Introduced in 1963, ZIP codes help identify the exact geographic location of addresses, making mail sorting and delivery efficient.
Why ZIP Codes Are Important
- Mail Delivery: Ensures accuracy and speed in postal services.
- Location Identification: Identifies specific cities, towns, and counties.
- Business Use: Helps companies plan deliveries, services, and marketing.
- Data & Demographics: Used for statistics, mapping, and population insights.
