Notes, Notations, link to Table
The red dashed lines on the map show groupings of islands, and do not
accurately reflect maritime boundaries.
The telephone codes shown above are either international country codes
(e.g.,
+596 for Martinique)
or North American area codes (shown as
+1 XXX).
The two-letter codes are
ISO 3166-1 codes,
most of which are also in use as Internet top-level domains.
The old AN code for the
former Netherlands Antilles has been discontinued in favor of the new codes
(SX for Sint Maarten,
CW for Curaçao, and
(BQ)
for Bonaire, Sint Eustasius, and Saba).
SX and CW are already in use on the Internet;
BQ may be activated some time in the future, but for now those islands
use the Netherlands .NL Internet domain.
Also, the French islands of
BL Saint-Barthélemy and
MF Saint-Martin
continue to use .gp (Guadeloupe) or
.fr (France) for Internet domains.
JM Jamaica added +1 658 as an overlay on its existing
North American telephone area code +1 876, effective
.
(Jamaica postponed implementation of the 658 overlay to allow more time for
businesses to update equipment to handle 10-digit dialing.
The first actual 658 numbers were assigned in
.)
Time Zones are shown in the same format used on the US/Canada map.
To convert to international format (offset from UTC/GMT), subtract 12 hours from the
time shown; for example, 7:00 (Eastern Standard Time) is
UTC–05:00.
The Bahamas, Turks & Caicos, Haiti, Bermuda, and Cuba observe
daylight saving time on the same schedule as the USA and Canada.
(Most of Mexico no longer observes DST.)
From the second Sunday in March until the first Sunday in November — for example,
from
until ,
or from
until
—
those areas are one hour later, as indicated by the 🌞 sunburst icon.
The rest of the year, they are on standard time, indicated by the ❄️ snowflake icon.
The Cayman Islands proposed observing DST in 2016, using the same dates as
the USA and Canada, but the plan was never implemented, so the Caymans remain
on Eastern Standard Time (7:00 / UTC–05:00)
year-round.
The other islands all observe standard time year-round.
Note that the Turks & Caicos Islands changed to Atlantic Standard Time
(UTC–04:00,
or 8:00 in LincMad notation),
year-round, but three years later switched back
to Eastern Standard/Eastern Daylight Time.
The Turks & Caicos do now observe DST.
Also, Venezuela created its own time zone, halfway between Colombia to the west
and the islands to the north and east, but in 2016 reverted to UTC–04:00
(8:00 in LincMad notation).
Details about the
Caribbean area codes
and other nearby country codes are presented in table format on a
separate web page.
As of ,
only
DO
Dominican Republic
continues to use area code
+1 809,
now overlaid with
+1 829
and +1 849.
Note that
PR Puerto Rico’s
+1 787
was overlaid with
+1 939.
Although BM Bermuda
is, strictly speaking, in the Atlantic Ocean (about 1000 km east of
South Carolina) rather than in the Caribbean Sea, it is included
on the map because it shared the old North American area code
+1 809 until 1996.
Bermuda is now +1 441;
+1 809 is now only
DO Dominican Republic.
