Israel phone number validator
How the phone number format works
- Format
- Israel phone number in national or international (+972) format
- Example
- +972502345678
Things to watch for
- Accepts national or international (E.164, e.g. +972...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$An Israeli phone number comes in two shapes: a mobile number — 05X followed by seven digits (050-1234567) — or a landline pairing a single-digit area code (2 Jerusalem, 3 Tel Aviv, 4 Haifa, 8 the south, 9 Sharon) with seven more digits. Both drop their leading 0 the instant +972 is added, but because a mobile prefix is two digits (05X) against a landline’s one (0X), the resulting international numbers differ in length: nine digits after +972 for mobile, eight for landline.
How this validator works
Enter the number in national form (0501234567) or full international form (+972501234567); this tool checks the digit count and the mobile or area-code prefix against Israel’s real numbering plan using Google’s libphonenumber, entirely in your browser. Mixing up the two lengths — typing a landline’s eight digits after +972 as if it were a nine-digit mobile, or vice versa — is the most common way a valid-looking Israeli number fails here.
What a pass doesn’t tell you
A pass confirms the number’s shape matches a genuine Israeli mobile or landline pattern — it says nothing about whether that specific SIM is active or the line connected. Israeli mobile numbers are reassigned once a plan lapses, so a well-formed number isn’t proof of ownership.
Scope: useful for catching a wrong area code, a missing digit, or a leftover 0 after +972 before a number reaches a form or SMS gateway — not a live reachability check.

phone number FAQ
Why is an Israeli mobile number one digit longer than a landline internationally?
A mobile number is 05X plus seven digits, nine digits total once the leading 0 is dropped for +972 (e.g. +972501234567). A landline pairs a single-digit area code — 2 for Jerusalem, 3 for Tel Aviv, 4 for Haifa — with seven digits, only eight digits after the 0 is dropped, one shorter than mobile.
What happens to the 0 in 050-1234567 when converting to +972?
It's removed. That 0 is a national trunk prefix used only for dialling within Israel; the international form is +972 followed directly by 501234567, not the full ten-digit national string.
Does a valid format check confirm the Israeli number is assigned to someone?
No. It confirms the prefix and length match a real Israeli mobile or landline pattern under the Ministry of Communications' numbering plan — not that the SIM is active or the line connected, which needs a carrier-side check this tool doesn't perform.
