Use examples as fixtures, not as proof of validity
National numbering plans change, and many countries support several lengths, services, and regional prefixes. A single display template cannot represent every valid number. Treat this directory as a fast fixture library for interface testing. Production applications should rely on a maintained numbering library and an authorized ownership-verification process where needed.
Reserved examples versus format-only examples
The United States guide uses the maintained 555-01XX fictional subscriber block. The India and China presets are format-only and clearly warn that an output could match an assigned number. The generator carries the same label into copied and exported results.
