Where is area code 135?

Answer 1

UK area code 01352 (or international +44 1352) is Mold (in northeastern Wales).

North American (USA, Canada, etc.) area code +1 352 is in north central Florida, including Gainesville and Ocala.

(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

Impossible to say without knowing what country you're asking about.

There is no area code 135 in North America (USA, Canada, etc.); area codes in North America never begin with 1.
