Keep all 10 national digits and add +1. Do not add a trunk zero.
3. Store one canonical value
Use +12025550123 for machine storage and format it for display at the edge of your application.

What makes United States phone input different
United States fixtures use the North American Numbering Plan: a three-digit area code, three-digit central-office code and four-digit line number. E.164 keeps all ten national digits after +1; there is no domestic trunk zero to add or remove.
The generated 202-555-01xx examples stay inside the NANPA 555-0100 through 555-0199 block reserved for entertainment and advertising. That makes this page useful for repeatable UI and documentation tests without presenting a subscriber lookup.
Check 1
Require an explicit US region when a national value has no +1 prefix.
Check 2
Keep exactly ten national digits for this fixture contract.
Check 3
Do not use a leading zero as a substitute for missing country context.

Frontend checks
Test empty input, pasted punctuation, a missing country code, one digit too few and one digit too many. Avoid using a single global regex for every country.
Test a JavaScript regexBackend storage
Store a normalized E.164 value and keep display formatting separate. Try the E.164 formatter or structural validator.
Production validation
Numbering plans change. Use a maintained numbering library and treat carrier, line type and reachability as separate checks.

United States phone number FAQ
Are these United States phone numbers real?
They are generated test fixtures, not verified subscriber lines. Even a structurally valid value may coincide with an assigned number unless it comes from an officially reserved fictional range.
What does the +1 calling code mean?
+1 is the international country calling code for United States. In E.164 format it appears after the leading plus sign and before the national number.
Can generated numbers receive calls, SMS or verification codes?
No capability is provided or verified. Do not call, text or use generated values for account verification.
Official numbering reference
Numbering rules can change. Check the North American Numbering Plan Administrator before enforcing production rules.
