Saint Barthélemy Phone Number validator
How the phone number format works
- Format
- Saint Barthélemy 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 Saint Barthélemy phone number is 9 digits under the country code +590, shared with Guadeloupe and French Saint Martin — mobile numbers typically start with 06 or 07 nationally. St. Barts (officially Saint-Barthélemy) became its own French overseas collectivity in 2007, splitting off from Guadeloupe’s administration, though the numbering plan it inherited stayed tied to the wider +590 zone rather than getting a dedicated code of its own.
How this validator works
Enter the number in national form (0690001234) 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 in your browser. Because Guadeloupe, St. Barts, and French Saint Martin all draw from the same +590 pool, this check confirms the number is valid somewhere in that plan — it can’t independently confirm the line is specifically registered on St. Barts rather than a neighboring island.
What a pass doesn’t tell you
A pass confirms the digits form a real number under the shared French Caribbean +590 plan — it doesn’t confirm the SIM is active or which of the linked islands actually issued it.
Scope: catches a malformed digit or wrong-length entry before a St. Barts number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Is Saint Barthélemy part of Guadeloupe?
Not administratively anymore. St. Barts split from Guadeloupe in 2007 to become its own French overseas collectivity, though it still shares Guadeloupe's +590 country code and much of its numbering plan with Guadeloupe and neighboring Saint Martin.
Why is a small Caribbean island so associated with luxury tourism?
St. Barts built its reputation on high-end tourism from the 1950s onward, drawing a wealthy international clientele to its beaches and duty-free shopping — a deliberate positioning that continues to shape the island's economy far more than its 25-square-kilometer size would suggest.
Does a valid check confirm a Saint Barthélemy number is currently active?
No. It only confirms the 9 digits match a real number under the shared +590 plan — not that the SIM is active or the landline connected, which needs a carrier-side lookup this free tool doesn't perform.
