Guadeloupe Phone Number validator
How the phone number format works
- Format
- Guadeloupe phone number in national or international (+590) format
- Example
- +590690001234
Things to watch for
- Accepts national or international (E.164, e.g. +590...) 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 Guadeloupe phone number is 9 digits under the country code +590 — mobile numbers typically start with 690. A French overseas department in the Caribbean, Guadeloupe’s main landmass is often described as butterfly-shaped, formed by the twin islands of Basse-Terre and Grande-Terre joined at a narrow channel; its +590 numbering plan also extends to the nearby French collectivities of Saint-Martin and Saint-Barthélemy, meaning the code alone doesn’t pin a number to Guadeloupe specifically.
How this validator works
Enter the number in national form (690001234) or full international form (+590690001234); this tool checks the 9-digit length and leading-digit pattern against the shared +590 numbering plan using Google’s libphonenumber, entirely client-side. As with Martinique, it’s easy to assume Guadeloupe shares mainland France’s +33 code since it’s an integrated French department — it doesn’t, and a number formatted with +33 fails validation here.
What a pass doesn’t tell you
A pass confirms the digits form a real number within the shared +590 plan — it doesn’t confirm the SIM is active, the landline connected, or that the number is Guadeloupe-based rather than Saint-Martin or Saint-Barthélemy, which digits alone can’t distinguish.
Scope: useful for catching a wrong-code mix-up with mainland France or a missing digit before a number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Why is Guadeloupe often described as butterfly-shaped?
Its two main islands, Basse-Terre and Grande-Terre, sit joined by a narrow strait in a way that resembles a butterfly's wings on a map — a geographic quirk unconnected to its phone plan, which runs under +590 like the rest of the French overseas department.
Does Guadeloupe share its phone code with any other territory?
Yes — Guadeloupe's +590 code is also used by the nearby French collectivities of Saint-Martin and Saint-Barthélemy, all administered under one shared numbering plan rather than each having a separate code of its own.
Does a valid check confirm a Guadeloupe number is currently active?
No. It only confirms the 9 digits match a real Guadeloupe numbering pattern — not that the SIM is active or the landline connected, which needs a carrier-side lookup this free tool doesn't perform.
