What is the country code for Saint Barthelemy?
Saint Barthelemy (St. Barths) is a 25 square kilometre French overseas collectivity in the Caribbean with a permanent population of roughly 8,450 — though annual visitor numbers of 300,000-400,000 dwarf that figure, driven by the island's status as a luxury tourism destination.
Until February 2007, St. Barths was a commune of Guadeloupe, and it retained Guadeloupe's +590 telephone code even after becoming its own separate overseas collectivity with its own ISO code (BL). Obtaining a dedicated ITU country code wasn't worth pursuing for an island this size, so +590 remains shared today with both Guadeloupe and French Saint Martin.
The most distinctive quirk for callers is the 'double 590' — since the local landline prefix (0590) happens to match the country code (590), a full international number reads as +590 590 XX XX XX. The same pattern shows up on Martinique (+596 596) and French Guiana (+594 594), all part of the same French overseas numbering convention.
代码 +590 被分配给 Saint Barthelemy 由 ITU 根据 E.164 计划制定。这 “+” 意思是“拨打您当地的国际退出代码”；在移动设备上，按住 0 来输入它。
这四个意思都是一样的——它们将您的电话连接到 Saint Barthelemy.
How to call Saint Barthelemy from anywhere
The pattern: your exit code + 590 + the 9-digit local number (dropping the leading 0). For landlines, that means the digits '590' appear twice in a row — once as the country code, once as the start of the local number.
Full example: +590 590 27 XX XX (landline) or +590 690 XX XX XX (mobile) — the repeated 590 in the landline format is correct, not a typo.
Saint Barthelemy phone number format explained
St. Barths numbers are 10 digits locally: landlines start with 0590, mobiles with 0690. There are no geographic area codes — the whole island shares one numbering block, split only by line type.
For international dialing, drop the leading 0 and prepend +590, giving +590 590 XX XX XX for landlines and +590 690 XX XX XX for mobiles.

+590 590 XX XX XX (the 590 appears twice — country code, then local prefix)

Common mistakes when calling Saint Barthelemy
Almost every failed international call is a formatting issue, not a network issue.
Dropping one of the two '590's in a landline number
A St. Barths landline in international format is +590 590 XX XX XX — the country code (590) and the local prefix (590) both happen to be the same digits. This is correct, not a typo — the same pattern applies to Martinique (+596 596) and French Guiana (+594 594).
Assuming a +590 number is definitely St. Barths
Guadeloupe and French Saint Martin share the exact same +590 code and prefixes — there's no way to tell the territory apart from the number alone.
Confusing French Saint Martin with Dutch Sint Maarten
Calling the French side (+590) from St. Barths is a local call; calling the Dutch side (+1 721) of the same island is a full international call at international rates.
Keeping the leading zero when dialing internationally
Drop the 0 from 0590/0690 when dialing from abroad — the correct international format is +590 590/690, not +590 0590/0690.
Assuming a US mobile plan roams free
Only EU/EEA mobile plans get 'Roam Like at Home' treatment on St. Barths — US and other non-EU visitors should expect standard international roaming charges or plan on a local SIM.
Tips to reduce the cost of calling Saint Barthelemy
EU visitors can rely on Roam Like at Home
As part of France and the EU, St. Barths honors EU roaming rules — European mobile plans work at domestic rates and allowances, subject to fair-use limits.
Buy a local SIM if visiting from outside the EU
Orange Caraibe, Dauphin Telecom, and Digicel all sell prepaid SIMs in Gustavia and at the airport — often more cost-effective than international roaming for US/Canadian visitors.
Use Wi-Fi calling or VoIP for the Dutch side of the island
Since calling Sint Maarten from St. Barths is a full international call despite the short distance, WhatsApp, FaceTime, or Wi-Fi calling avoid the per-minute charge.
Consider Dauphin Telecom for local service quality
As the only independent, locally-owned operator, Dauphin Telecom is known for strong customer service and community ties on St. Barths and Saint Martin.
