Where is phone area 972 from?

Answer 1

North American area code +1 972 is in Dallas, Texas.

Telephone country code +972 is Israel.

(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.)
