How to use the proper Country Codes for Island Territories
If you are using Aircall or another calling software, it is essential to input the correct country code to successfully dial numbers in these territories. Using the mainland country code (e.g., +33 for France) will not work for calls directed to these island territories. Instead, always use the specific country code listed above.
For example:
- To call Guadeloupe, you must use +590 instead of France’s +33
- For Sint Maarten (Dutch), use +1-721 rather than the Netherlands’ +31
