Romania phone number validator
How the phone number format works
- Format
- Romania phone number in national or international (+40) format
- Example
- +40712034567
Things to watch for
- Accepts national or international (E.164, e.g. +40...) 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 Romanian phone number carries a 9-digit national number behind a trunk 0 that’s dialed domestically but dropped for +40. A mobile number starts with 07 followed by 7 more digits (0722 123 456); a landline starts with 02 or 03 plus an area code — 021 for Bucharest, for instance — followed by a subscriber number that fills out the remaining length.
How this validator works
Enter the number nationally (0722123456) or with the country code (+40722123456); this tool checks digit count and prefix range against Romania’s real numbering plan using Google’s libphonenumber, entirely in your browser. Converting to +40 form always drops the leading trunk 0, leaving exactly 9 digits behind it — a number that still starts with 0 after +40, or runs short a digit, fails the check immediately.
What a pass doesn’t tell you
A pass confirms the digits match a real Romanian mobile or landline pattern — it says nothing about whether that SIM currently has an active plan or the landline is in service. Format validity and live-connection status are separate questions this tool doesn’t answer.
Scope: use this to catch a missing digit, an extra digit, or a kept trunk 0 after +40 before a number reaches a booking form or SMS platform — not as proof the SIM is currently active.

phone number FAQ
What happens to the leading 0 in a Romanian mobile number when converting to +40?
It's dropped. The 0 in 0722 123 456 is a national trunk prefix, so the international form is +40722123456 — the remaining 9 digits (722 123 456) are what identify the network and subscriber.
How can I tell a Romanian mobile number from a landline?
By the second digit after the trunk 0: mobile numbers use 07 (0722 123 456), while landline numbers use 02 or 03 followed by a 1- or 2-digit area code, such as 021 for Bucharest — both are 9 digits after the 0.
Does a valid Romanian number check confirm the SIM is active?
No. It only confirms the digits match a real Romanian mobile or landline pattern — it can't confirm a prepaid SIM is loaded or a landline connected, since that requires a carrier lookup this tool doesn't perform.
