There is no telephone area code 010 in the United States, nor in North America. (The US is part of a unified numbering plan for North America, including Canada and 18 island nations and territories in or near the Caribbean.)
01 is the prefix for operator-assisted international calls from North America, but it can never be followed by another zero.
There are codes beginning with 101, including some beginning with 1010, used to select a particular long distance company on a per-call basis. For example, you might dial 101xxxx-1-999-555-0123.
There are several countries in which 010 is a valid domestic area code.
The telephone country code for Italy is +39. The area code for Genova (Genoa) is 010, or +39 010 in international format. Note: unlike most countries, you DO NOT drop the trunk prefix 0 from the Italian domestic area code when putting the number in international format.
The 874 area code is an invalid unassigned number. If you are getting calls from this area code they are being "spoofed".
It has the area code 082.
Oxford, PA has two area codes. They are 484 and 610. The area code that a number has will be dependent on what area of Oxford the number is from, or when the phone number was created.
.010
The America code is 1. In order to get the party you wish, the number is 1+specific area code+phone number.
Most people learn their area code as children, when they're old enough to remember their home telephone number. Older telephones will have a label that shows the telephone number with the area code. Your phone bill will have your number with the area code. You can look up the area code for your city or another city on the web.

The telephone area code of your phone number.
There is no country code 010, because country codes cannot begin with zero. Country code +1 is North America (USA, Canada, etc.), but there are no valid numbers beginning with +1 0.There are some countries, including Japan, that use 010 as the international access prefix for dialing an outbound international call.(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.)
Area code 877 was created in 1998 for toll free calls. Calls to number in this area code may be restricted by the customer to whom the number is assigned.
The same local telephone number can exist in many different area codes. (After all, that's the whole point of area codes.) If you know where the telephone number is from, and if that place has only one area code, you can find out that way.
