payable
Normalizes phone numbers into a canonical E.164 match key so formatting variants like '(415) 555-0100' and '+1 415-555-0100' collide. Strips formatting to digits and returns E.164, country code, and validity. Deterministic and instant — no carrier lookups. Use it for phone dedup, phone normalization, contact record linkage, or as an E.164 formatter.
