- Example
- +61412345678

- 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 Christmas Island phone number uses Australia’s +61 country code and mobile-number shape, since Christmas Island is an Australian external territory rather than an independent country with its own numbering plan. Located in the Indian Ocean well south of Indonesia, the island is best known for its annual red crab migration — tens of millions of crabs crossing roads and forest floor each wet season — one of the largest animal migrations on Earth relative to the island’s tiny size.
How this validator works
Enter the number in national form (0412345678) or full international form (+61412345678); this tool checks the digit count and pattern against Australia’s real numbering plan using Google’s libphonenumber, entirely in your browser. Because Christmas Island has no dedicated country code, this check validates the number exactly as it would a mainland Australian one — it can’t independently confirm the line is specifically Christmas-Island-based.
What a pass doesn’t tell you
A pass confirms the digits form a real number under Australia’s shared +61 plan — it doesn’t confirm the SIM is active or registered to a Christmas Island address specifically.
Scope: catches a mistyped digit or malformed prefix before a number reaches a form — not a substitute for a carrier lookup.

phone number FAQ
Does Christmas Island have its own phone country code?
No. Like the Cocos (Keeling) Islands, Christmas Island is an Australian external territory and uses Australia's +61 country code and numbering plan rather than a dedicated code of its own.
What is Christmas Island best known for?
Its annual red crab migration, when tens of millions of native red crabs move from the island's forests to the ocean to spawn — a spectacle significant enough that roads are closed and crab bridges built to protect the migration, despite the island's small size and shared Australian phone plan.
Does a valid check confirm a Christmas Island number is currently active?
No. It only confirms the digits form a real number under Australia's shared +61 plan — not that the SIM is active, which needs a carrier-side lookup this free tool doesn't perform.
