How the phone number format works

Format
French Guiana phone number in national or international (+594) format
Example
+594694201234

Things to watch for

  • Accepts national or international (E.164, e.g. +594...) format
  • Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
Regex for phone number
^[+]?[0-9 ()\-]{6,}$

A French Guiana phone number is 9 digits under the country code +594 — mobile numbers typically begin with 06 or 07 nationally. Located on South America’s northeast coast, French Guiana is a full overseas department of France, constitutionally equivalent to a mainland French region, and hosts the Guiana Space Centre at Kourou, Europe’s spaceport, chosen for its location near the equator.

How this validator works

Enter the number in national form (0694201234) or full international form (+594694201234); this tool checks the 9-digit length and leading-digit pattern against French Guiana’s real numbering plan using Google’s libphonenumber, entirely client-side. As an overseas department, French Guiana has its own dedicated +594 code distinct from mainland France’s +33 — don’t assume the two share a numbering plan just because both use French administration and currency.

What a pass doesn’t tell you

A pass confirms the digits form a real French Guiana number shape — it doesn’t confirm the SIM is active or the landline connected, a separate carrier-side question this tool doesn’t try to answer.

Scope: useful for catching a wrong-code mix-up with mainland France before a French Guiana number reaches a form — not a substitute for a real lookup service.

phone number FAQ

Is French Guiana part of France or a separate country?

French Guiana is a full overseas department and region of France, meaning it's constitutionally as much a part of France as Provence or Brittany — not a colony or associated territory. It uses the euro, French law, and its own +594 slice of the French numbering system.

Why is French Guiana significant for space launches?

It hosts the Guiana Space Centre at Kourou, Europe's primary spaceport, chosen partly for its near-equatorial location, which gives rockets a velocity boost from Earth's rotation — a strategic asset that has little to do with its phone numbering but shapes a large share of the local economy.

Does a valid check confirm a French Guiana number is currently active?

No. It only confirms the 9 digits match a real French Guiana numbering pattern — not that the SIM is active, which needs a carrier-side lookup this free tool doesn't perform.
