# DESCRIPTION

Number::Phone::JP::AreaCode provides utilities for Japanese area code of phone.
You can retrieve area code by address and opposite.

If you want to know about Japanese area code of phone, please refer [http://www.soumu.go.jp/main\_sosiki/joho\_tsusin/top/tel\_number/shigai\_list.html](http://www.soumu.go.jp/main_sosiki/joho_tsusin/top/tel_number/shigai_list.html) (Japanese web page).

# FUNCTIONS

All of functions return `undef` if result of retrieving is nothing.

- address\_by\_area\_code($area\_code)

    Retrieve addresses list by area code.
    This function returns hash reference like;

        {
            addresses         => [ 'еЊ—жµ·йЃ“в—Їв—Їеё‚Г—Г—з”є', 'еЊ—жµ·йЃ“в—Їв—Їеё‚в–ів–із”є' ],
            local_code_digits => '3'
        }

    `addresses` is the list of addresses that belong with area code.
    `local_code_digits` is the number of digits of local code.

    You can append country code (0) or not. As you like it!

- area\_code\_by\_address($address)

    Retrieve area code by address (perfect matching). `$address` __MUST__ have prefecture name.
    This function returns hash reference like;

        {
            area_code => '72',
            local_code_digits => '3'
        }

    `area_code` is the area code which excepted country code (0).
    `local_code_digits` is the number of digits of local code.

- area\_code\_by\_address\_prefix\_match($address)

    Retrieve area code by address (prefix matching and longest matching). `$address` __MUST__ have prefecture name.
    This function returns hash reference that is the same as `area_code_by_address`.

- area\_code\_by\_address\_fuzzy($address)

    Retrieve area code by address (partial match). `$address` __MUST__ have prefecture name.
    This function returns hash reference like;

        {
            '大阪府◯◯市' => {
                area_code         => '6',
                local_code_digits => '4',
            },
            '大阪府△△市' => {
                area_code         => '72',
                local_code_digits => '3',
            }
        }
