Algeria Phone Number validator
How the phone number format works
- Format
- Algeria phone number in national or international (+213) format
- Example
- +213551234567
Things to watch for
- Accepts national or international (E.164, e.g. +213...) 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 Algerian mobile number is nine digits after the +213 country code, built from a single mobile prefix — 5, 6, or 7 — followed by eight more digits, e.g. +213551234567. Domestically that same number is dialed with a leading trunk 0 in front, giving the familiar 10-digit form 0551 23 45 67; the 0 is never part of the international form and gets dropped the moment +213 replaces it.
How this validator works
Enter the number as dialed at home (0551234567) or already converted to international form (+213551234567); this tool checks the digit count and the 5/6/7 mobile prefix against Algeria’s real numbering plan using Google’s libphonenumber, entirely in your browser. The most frequent mistake it catches is a leftover 0 tacked onto the front of the +213 form, which pushes the number to 10 digits after the country code instead of nine and fails immediately.
What a pass doesn’t tell you
A pass confirms the digits are shaped like a genuine Algerian mobile number — not that the SIM behind it is active today. Algeria’s prepaid market reassigns dormant numbers, so a well-formed number is no guarantee it currently belongs to anyone reachable.
Scope: use this to catch a missing digit, a wrong mobile prefix, or a leftover 0 after +213 before a number reaches a form or SMS platform — not as proof it rings through.

phone number FAQ
How many digits does an Algerian mobile number have in national form?
Ten digits including the leading 0 — for example 0551 23 45 67 — built from a trunk 0, a mobile prefix of 5, 6, or 7, and eight more digits. Drop that 0 for the +213 international form and only nine digits remain.
Why does +2130551234567 fail validation?
Because the leading 0 was kept after the country code was added. Algeria's trunk 0 exists only for domestic dialing; the correct international form is +213551234567, nine digits after +213, not ten.
Does a valid result mean the Algerian number is currently reachable?
No. It only confirms the digits fit a real Algerian mobile pattern under the national numbering plan — it can't confirm the SIM is topped up, registered, or currently switched on, which needs a network-side check this tool doesn't perform.
