postal codes
Postal codes are alphanumeric or numeric sequences assigned to specific geographic areas to help postal services efficiently sort and deliver mail. They function as a precise address component, indicating regions, neighborhoods, or streets, which speeds up the sorting process and ensures accurate delivery. Postal codes can also assist in demographic analysis, logistics planning, and regional organization. They vary by country in format and length but all serve the fundamental purpose of streamlining mail distribution and improving postal accuracy.
