Where is area code 001 800?

Answer 1

00 isn't part of the area code or country code, it is a commonly used international access prefix.

If 00 is your international access prefix, then you're really asking about telephone country code and area code +1 800. Country code +1 is North America, including the USA, Canada, and certain nearby islands, mostly in the Caribbean. Area code +1 800 is used for toll-free calls within North America. It may be possible to dial a North American toll-free number (Area codes +1 800, +1 888, +1 877, +1 866, +1 855, and +1 844) from other countries, with the caller paying the international call charges. If that doesn't work, try searching the web to find a regular geographic number for the company you're trying to contact.

Alternatively, if your international access prefix is 001, then you're asking about telephone country code +800, which is UIFN, Universal International Freephone Numbers. A call to a +800 number should be toll-free from any country from which the call will complete.

It can be very confusing to quote an international telephone number with the international access prefix, since different countries use different prefixes for outbound international calls. To avoid that confusion, it is best to quote an international telephone number beginning with the plus symbol and the actual telephone country code, omitting any access prefix.

(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.)
