A domestic-format example is (721) 520-5XXX; its international form is +1 721 520 5XXX. Final subscriber digits are masked with X, so this is a format guide rather than a number to call. The example comes from libphonenumber-js 1.13.11 example metadata; check the current national plan before relying on a number range.
Convert the number for +1
The national example does not show an extra domestic access prefix. Add +1 before the complete national number.
+1 does not identify Sint Maarten by itself
+1 is also used by Antigua & Barbuda, Anguilla, American Samoa, Barbados, Bermuda and 19 other destinations. The example +1 721 520 5XXX includes the destination-identifying digits after the shared code. Dadaphone must identify the complete number as Sint Maarten before you rely on the destination or rate.
Check mobile and landline availability separately
The masked metadata example is a mobile format; it does not prove that range is reachable. Dadaphone currently offers only a landline route to Sint Maarten; mobile calling is unavailable even though the metadata example shows a mobile format. Geographic landlines, mobiles, toll-free ranges, premium services and short codes can route differently. Confirm the number type, availability and price for the complete number before calling.
If the Sint Maarten number is rejected
Check the country code, national-number length and domestic access prefix. For a business, use its published international geographic number rather than an internal extension or local short code. Never add digits by guesswork.
Check local time before calling
Sint Maarten is recorded in UTC-04:00. Check the recipient's current city and date, especially when the destination spans more than one time zone.
