Where in North America is area code 766?

Answer 1

Country code +7 is shared by Russia and Kazakhstan. There are currently no valid numbers beginning with +7 6, but that numbering range is reportedly reserved for Kazakhstan.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)

Answer 2

North American area code +1 767 is the Caribbean island nation of Dominica.

(Note that Dominica is not the same thing as Dominican Republic.)

Answer 3

There is no area code +1 766 in North America (USA, Canada, etc.). It is an unused, unassigned code. Also, all North American area codes with the second and third digits the same (for example, 500, 800, 844, or 766) are reserved as "easily remembered" codes for non-geographic purposes like toll-free numbers, premium numbers, and personal numbers, so if 766 is ever assigned, it will not be as an ordinary geographic area code.
