United States numbers & Carrier Lookup checks

Before a Carrier Lookup check, numbers are normalised to E.164 — the international format with the correct dial code and national length — so mixed local formats in your list do not silently fail. A valid United States number looks like +1 XX XXXX XXXX; anything that cannot be normalised to that shape is flagged rather than billed.
