How to format a New Jersey phone number
US numbers have ten digits: the area code, a three-digit exchange and a four-digit line number. A New Jersey number is written as (201) 555-0123 for display, or +12015550123 in E.164 format for storage.
Safe numbers for testing
The range 555-0100 to 555-0199 is reserved for fictional use in every area code. Our generator combines these with real local area codes, so test data looks right without reaching a real person.
Why overlays matter for your forms
With overlays, you cannot guess a city from its area code alone, and people who move keep their numbers. Use area codes for display and formatting, not for location checks.
Create realistic New Jersey addresses for testing, with real cities, counties and ZIP codes.
