How to dial a number in Sint Maarten from anywhere: the dialling helper.

Test a pattern

Tick the line types you accept, copy the combined pattern, and paste numbers to see which range each one falls in. Numbers are reduced to their national digits first (no spaces, no +1, no trunk prefix 1); nothing leaves your browser.

^(?:7215(?:1[02]|2\d|5[034679]|8[0-24-8])\d{4}|7215(?:4[2-8]|8[39]|9[056])\d{4})$

Walk the prefixes

Type the first digits of a number in national form, or tap them: the operators holding blocks under those digits, then the block a full prefix falls in. 10 blocks held by 1 operators are on record.

Cheat sheet

Line types and their regular expressions

Match each pattern against the national significant number: digits only, without the trunk prefix 1 and without +1. The patterns follow the national numbering plan and are anchored here.

^(?:7215(?:1[02]|2\d|5[034679]|8[0-24-8])\d{4})$

^(?:7215(?:4[2-8]|8[39]|9[056])\d{4})$

^(?:8(?:00|33|44|55|66|77|88)[2-9]\d{6})$

^(?:900[2-9]\d{6})$

^(?:52(?:3(?:[2-46-9][02-9]\d|5(?:[02-46-9]\d|5[0-46-9]))|4(?:[2-478][02-9]\d|5(?:[034]\d|2[024-9]|5[0-46-9])|6(?:0[1-9]|[2-9]\d)|9(?:[05-9]\d|2[0-5]|49)))\d{4}|52[34][2-9]1[02-9]\d{4}|5(?:00|2[125-9]|3[23]|44|66|77|88)[2-9]\d{6})$

Carrier prefix blocks

The operator each prefix block was allocated to, in national form, from the published allocation records for +1. Numbers are portable, so this is the original allocation, not necessarily the carrier serving a number today.

Questions developers ask

How many digits does a phone number in Sint Maarten have?

Mobile numbers have 10 national digits (7 when dialled locally). Fixed line numbers have 10 national digits (7 when dialled locally). That is the national number, without the country code +1 and without the trunk prefix 1.

What is the country code for Sint Maarten?

+1. From abroad, dial your own exit code, then 1, then the national number without its trunk prefix 1. From inside Sint Maarten, the exit code for international calls is 011.

Which prefixes are mobile numbers in Sint Maarten?

Mobile numbers in Sint Maarten use area code 721 and 26 of its central office codes (the three digits after the area code), such as 510, 553, 588; the mobile regular expression on this page lists them all (example: (721) 520-5678). Dialled within the North American Numbering Plan, every number reads alike: 1, the area code, then seven digits.

Can a mobile number in Sint Maarten be ported to another carrier?

Yes. Sint Maarten has mobile number portability, so a prefix tells you the carrier a number was originally allocated to, not necessarily the one serving it today. Only a live carrier lookup (an HLR or MNP query) answers that.
