Decoder - Helpful Hints and Frequently Asked Questions
AmeriCom Area Decoder provides users with current information related
to area, city, and country telephone codes. This information is
gathered from a myriad of sources, checked for known anomolies and
inconsistencies, and compiled for distribution via the AreaDecoder.com
that AmeriCom does not currently provide white pages information,
postal code lookups, or reverse phone number lookup. If you are
trying to enter any of this information, you will not necessarily
get the results you are looking for.

How come I don't get what I'm looking for?
are probably entering in too much data (i.e. part or all of the
phone number instead of just the country, city, and/or area code)
or entering data that is irrelevant to the search.
phone number can be broken down into three parts: the country code,
the city or area code, and the actual phone number. In addition,
each continent and/or country has different rules for placing national
and international calls. Quite often leading numbers, such as 0's
and/or 1's, are misconstrued as being part of the country or city
code, when in fact they are not. These numbers are used by the local
phone company to place long distance calls within the country or
international long distance calls. For example, 011 is the US code
for dialing internationally, and will not return any values if you
include in the phone number.
cases include the way a particular region delimits (seperates) the
parts of a phone number. Some countries use dashes (-), some use
periods (.) or commas (,), and some use slashes (/). The Area Decoder
uses a plus sign (+) to represent the country code (i.e. 1 for the
US, Canada, and Carribean countries), and dashes to seperate the
country code from the city code and phone number.
but not least, the system will try to "guess" which city,
state, and/or country you are looking for if the spelling is incorrect.
Because we use the American English spelling for most countries,
native language spellings will most like produce errors or approximate
lookups. Cities, on the other hand, may be in the native spelling
as well as (or instead of) the English spelling. Trying both is
your best bet.
How can I better optimize my searches? (continuation of #1)
the case of a US phone number 555-1212 in Utah, you would dial 1-801-555-1212
from within the US. The general international form would read +1-801-555-1212.
To use this information in a lookup, you would type +1-801 in the
Simple Search field, or 1 in the Country Code field and 801 in the
City or Area Code field of the Power Search section. (The Simple
Search defaults to US area codes if you only type in three digits:
"801" typed alone in this case would return Salt Lake
numbers may be a little different. If you're in Holland, for example,
you would dial a "0" (zero) for long distance calls. In
the case of a phone number in The Hague, The Netherlands, a national
long distance call would be read as 070.555.5555. The international
form, however, would read +31-70-555-5555 (notice the dropped leading
"0" in front of the 70). For a Simple Search lookup, you
would therefore type +31-70 to get the city information. On the
Power Search section, you would type 31 in the Country Code field
and 70 in the City or Area Code field.
Why doesn't AmeriCom provide more information?
has specialized in accurate area code information on the Internet
for the past 5 years. Until recently we have not needed to provide
more. However, due to overwhelming customer response, we have decided
to expand our services. Keep an eye out for future development and
How come the information is incorrect?
gather our information from multiple sources across the globe. Because
the telecommunications industry is growing and expanding so rapidly,
it is difficult to keep up with all of the changes. Additionally,
the data is not always correct at the source. Our thanks go to the
many customers who help us update our information and keep it as
correct as possible.
What can I do if I have an idea or suggestion?
have a feedback form that you can fill out and send to us. We use
the information to determine where our efforts would be best spent.

Why does my search take so long?
your search does not match a unique city, state, and/or country
name exactly, the system will do an approximate search or a duplicate
search, returning multiple values. This second and third pass can
take a couple of seconds longer, especially under heavy system load.
How can you tell which part is the country code and which part is
the city code?
are a few rules that country and city codes follow that will help
you determine where you are calling, and can make your searches
more effective. All international country codes are one, two, or
three digits long. North America is generally 1 (excluding Mexico),
European countries generally have two digit codes, and smaller countries
three. Area codes are three digit codes used primarily in the US
and Canada. City codes are non-US city or area codes that are generally
two to four digits long, depending upon the native phone company's
