Where in North America is area code 536?

Answer 1

There is no telephone area code +1 536 in North America (USA, Canada, etc.).

Telephone country code +53 is Cuba.

(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

Area codes 500, 533, 544, and 566 are used for "Personal Communication Services."
