Zelle phone-number lookups resolve to full contact profiles, rate-limited at 120/min
MicahBerkley · x · 2026-09-25
MicahBerkley describes a free way to enrich contact data: Zelle allows lookups by phone number or name and resolves them into fairly complete contact profiles. The rate limit is 2 requests per second (120/min) — slow, but a surprisingly effective free method for enriching outlier records. The trick also underscores the privacy risk of phone-number lookups in payment apps.
