How to format a Tennessee phone number
US numbers have ten digits: the area code, a three-digit exchange and a four-digit line number. A Tennessee number is written as (423) 555-0123 for display, or +14235550123 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.
