Poland phone number validator
How the phone number format works
- Format
- Poland phone number in national or international (+48) format
- Example
- +48512345678
Things to watch for
- Accepts national or international (E.164, e.g. +48...) 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,}$A Polish phone number is always 9 digits, with no separate area code and no trunk prefix — Poland closed its numbering plan years ago so every number, mobile or landline, is dialed the same way regardless of region. Mobile numbers fall within the 5, 6, 7, and 8 prefix ranges (512 345 678); numbers built on the old regional codes, like 12 for Kraków or 22 for Warsaw, now function as ordinary 9-digit numbers rather than a separate area code plus local number.
How this validator works
Enter the 9 digits alone (512345678) or with the country code (+48512345678) — this tool checks length and prefix range against Poland’s real numbering plan using Google’s libphonenumber library, entirely in your browser. Because there’s no trunk zero to drop, the national and international forms differ by exactly the +48 prefix and nothing else, unlike countries where a leading 0 has to be stripped first.
What a pass doesn’t tell you
A pass confirms the 9 digits fall within a real Polish number range — it says nothing about whether that specific mobile or landline is currently active. Format validity and live-line status are separate questions; this tool only answers the first one.
Scope: catch a missing digit, an extra digit, or a wrongly-kept 0 in front of +48 before the number reaches a booking form or SMS gateway — not proof the number rings.

phone number FAQ
How many digits does a Polish phone number have?
Exactly 9, with no area code and no trunk prefix — that holds for both mobile and landline numbers, and it stays 9 digits whether dialed domestically or converted to +48 for international calls.
Do I need to drop a leading 0 when adding +48 to a Polish number?
No. Poland closed its old area-code system and removed the trunk 0 entirely, so the international form is simply +48 followed by the same 9 digits — nothing added, nothing stripped.
How can I tell a Polish mobile number from a landline?
By the leading digit range: mobile numbers generally fall in the 5, 6, 7, and 8 prefix ranges, while landline-style numbers use ranges tied to the old regional codes (like 12 for Kraków or 22 for Warsaw) — both are still 9 digits total.
