Planning Letter 396

The Government of St. Maarten, Netherlands Antilles, had requested, and was granted, entry into the NANP. The new 721 NPA has been assigned to serve St. Maarten (previously under country code 599), with the introduction timeline as follows:
5/31/10 –
~ Start of permissive dialing (the new NPA or current 599 country code may be used for a dialed number terminating in St. Maarten).
~ The latest date for all international and domestic carriers to activate 721 NPA. A test number for verification of 721 activation will be provided at a later date.
11/30/10 –
~ End of permissive dialing and start of mandatory dialing of the new NPA.

Once the permissive dialing period ends, calls dialed with the 599 country code will receive a recorded message instructing callers to dial the correct country (1) and area code (721). The new 721 NPA will only be in effect for St. Maarten, the remainder of the Netherlands Antilles will continue to use country code 599. For more information, please visit www.nanpa.com.
