Where is area code 171?

Answer 1

There is no telephone area code 171 in North America (USA, Canada, etc.). North American area codes cannot begin with 1.

There is no longer a telephone area code 171 in the United Kingdom (+44 171 or 0171 in domestic format). That code was used for inner London from 1995 until 2000, when London was reunified under the single area code 020. Numbers that were in area code 0171 changed to 020 and added the digit '7' to the front of the local number to make the new 8-digit local number.

Other countries may have a domestic telephone area code 171 or similar.

Telephone country code +1 is North America, but you need the three-digit area code (i.e., one more digit) to narrow down the location. For example, +1 713 is Houston, Texas, but +1 714 is part of Orange County, California.
