The NANPA assigns NPA-NXX codes for the United States, not for Canada
nor the non-US NANP-Caribbean. At NANPA's site, you can get c.o.code
detail for the 48-states/DC, Alaska, Hawaii, Guam/CNMI (in the
Pacific), as well as the two US Caribbean locations of Puerto Rico and
the US Virgin Islands.
When NANPA was spun out of Bellcore, it was intended for the new NANPA
to take over c.o.code (NPA-NXX) assignments for all of the _US_
jurisdictions away from the dominant incumbent local telco in that
area code, but Canada and the non-US Caribbean didn't indicate that
they would turn over c.o.code administration to the NANPA.
You can get (web page) lists of c.o.code assignments in Canada, from
the Canadian Numbering Administrator's website (the CNAC is presently
contracted to SAIC, who are the current owners of Telcordia; Telcordia
was previously Bellcore when the at-that-time seven RBOC holding
companies each owned an equal 1/7th of Bellcore).
The CNAC's website is http://www.cnac.ca
The "Numbering Resources" page is http://www.cnac.ca/numb_res.htm
You can click on a map of Canada at http://www.cnac.ca/mapcodes.htm
to go to individual area code pages of c.o.codes for Canada.
The c.o.code administration for the Canadian NPAs/provinces _USED_ to be
handled by the dominant incumbent local telco for that NPA, but last year,
this was transferred over to the (SAIC's) CNAC.
The 600 "SAC" is a Canada-only Special Area Code, but I don't think
there is much activity on it - it is for Canadian data functions,
Canadian international-inbound functions, Canadian "caller-pays"
cellular airtime, etc. The list of 600-NXX code assignments to
_carriers_ (similar to the way 800-NXX codes _USED_ to be assigned to
carriers prior to 1993/94's introduction of "full" portability; and
the way of 456-NXX codes, 900-NXX codes, and 500-NXX codes are
presently assigned to carriers), can be found at:
http://www.cnac.ca/sac_600.htm
As for the Caribbean, when it was all under area code 809, whoever was
NANPA at the time assigned the c.o.codes, or at least managed the
"range" of c.o.codes (at one time, you could get a decent idea of
which country/island the NNX code in 809 was located in by the first
one or two digits of the c.o.code, but that changed prior to
introduction of N0X and N1X c.o.codes in 809, which was prior to each
island/country of the NANP-Caribbean breaking off from 809 into its
own unique area code.
The NANPA prior to 1984 was AT&T Long Lines and AT&T HQ/Gen'l Depts;
With divestiture in 1984, through 1997, Bellcore was the NANPA;
In 1998/1999, Lockheed-Martin moved the NANPA out of Bellcore in NJ,
but now Warburg-Pincus' "Neustar" is the NANPA, but remaining in
Washington DC, with most of the same staff that was with NANPA under
Lockheed.
When 809 began to break up into unique area codes for each island or
country in the NANP-Caribbean, c.o.code assignments was transferred
over to the island -- usually the local/island government's regulatory
agency or entity created by regulatory/government, but sometimes the
c.o.code assignment was now handled "in association with" the dominant
incumbent local telco (usually Cable & Wireless or a
subsidiary/venture of C&W usually in association with island gov't; or
in the case of the Dominican Republic -- GTE/Verizon's "CoDeTel" is the
dominant incumbent LEC).
The Dominican Republic is the NANP-Caribbean island/country that
retained NPA 809. You can go to the following webpages of GTE/Verizon
Codetel or one of the competitors (Tricom) to get some kind of list of
c.o.codes in NPA 809, Dominican Republic:

Of course, you can always download the "NNAG" from Telcordia-TRA which
is a part of the LERG; the NNAG (NPA-NXX Activity Guide) is issued
monthly, giving c.o.code change information in the NANP and can be
downloaded FOR FREE from Telcordia-TRA's website,
http://www.trainfo.com
Other TRA products, such as the LERG (Local Exchange Routing Guide) or
the NNACL (NPA-NXX Active Code List) must be purchased from TRA, but
their catalog of products is available from the TRA
website. NANP-Caribbean c.o.code data (as well as Canadian NPA-NXXes)
are included in TRA's products.
