Is there an area code 0454?

Answer 1

045 is a valid domestic area code in several countries.

There is no area code +1 045 in North America (USA, Canada, etc.).

There is no area code 045 in the UK (country code +44).

In Ireland, area code 045 (or +353 45 in international format) is Naas, Kildare, and Curragh.

In Italy, area code 045 (or +39 045) is Verona.

Country code +45 (dialed as 00 45 from many places) is Denmark.

(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.)

There is probably an area code 0454 in some country somewhere.
