Gibraltar Phone Number validator
How the phone number format works
- Format
- Gibraltar phone number in national or international (+350) format
- Example
- +35057123456
Things to watch for
- Accepts national or international (E.164, e.g. +350...) 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 Gibraltar phone number is 8 digits under the country code +350 — a mobile number starts with 5 (5712 3456), landlines with 2. Gibraltar is a British Overseas Territory at the southern tip of the Iberian Peninsula, and while it shares the pound sterling and close constitutional ties with the UK, its telecoms numbering runs on its own dedicated country code rather than sitting inside the UK’s +44.
How this validator works
Enter the 8 digits alone (57123456) or with the country code (+35057123456) — this tool checks the digit count and leading-digit range against Gibraltar’s real numbering plan using Google’s libphonenumber, entirely client-side. There’s no trunk zero to strip, so the national and international forms differ only by the +350 prefix, and a number formatted like a UK mobile won’t pass here unless it also matches Gibraltar’s own assigned ranges.
What a pass doesn’t tell you
A pass confirms the 8 digits fall within a real Gibraltar numbering range — it doesn’t confirm the line is connected or the mobile SIM active. Format validity and current reachability are separate questions this tool doesn’t try to answer.
Scope: useful for catching a mistyped digit or a wrong-country assumption before a Gibraltar number reaches a form or SMS gateway — not a substitute for a real lookup service.

phone number FAQ
Is a Gibraltar number part of the UK's +44 numbering plan?
No. Gibraltar is a British Overseas Territory and uses the pound sterling and UK institutions in many respects, but its phone numbers carry a distinct country code, +350, separate from the UK's +44.
Is there a trunk 0 to drop when converting to +350?
No. Gibraltar has no national trunk prefix, so the 8 digits used domestically are the same 8 digits that follow +350 internationally.
Does a valid check confirm the Gibraltar line is currently active?
No. It only confirms the 8 digits match a real Gibraltar numbering range — not that the SIM is active or the line connected, which needs a carrier-side lookup this tool doesn't perform.
