The Problem

Israeli phone numbers come in a variety of formats: with a +972 prefix, with a leading 0, with or without hyphens, and sometimes without an area code altogether. When a system receives numbers from forms, Excel files, or APIs, format inconsistency causes duplicates, SMS delivery failures, and dialing errors. Without automatic normalization, every number requires manual handling.
