Frequently Asked Questions

Postal Code System
In the United States, postal codes are known as ZIP Codes, introduced by the USPS in 1963. The standard ZIP Code is a 5-digit sequence (e.g. 10012) designating specific regional hubs or delivery offices. A 9-digit extension, known as ZIP+4, is also supported to pinpoint exact street segments, apartment complexes, or mailing boxes for accelerated delivery sorting.
Dialing Format & Area Codes
US phone numbers adhere to the North American Numbering Plan (NANP), utilizing a standard 10-digit format: a 3-digit Area Code followed by a 7-digit local subscriber number. Our platform indexes genuine area codes for major US cities and provides mock phone numbers following local telecom guidelines to assist software QA testing.
