tel-carrier-db

A static cache of http://fonefinder.net's database, adapted for use with Node.js.

Usage

npm install --save tel-carrier-db

(function () {
  'use strict';

  var telDb = require('tel-carrier-db')
    , info
    ;

                    // country, area code, prefix, exchange/subscriber/line
  info = telDb.lookup('1', '801', '360', '5555');
  if (info) {
    console.log(info);
  } else {
    console.log('Not found');
  }
}());

Example Output:

{ "number": "+18013605555"
, "city": "PROVO"
, "state": "Utah"
, "st": "UT"
, "company": "CELLCO PARTNERSHIP DBA VERIZON WIRELESS - UT"
, "type": "WIRELESS PROV"
, "carrier": "verizon"
, "carrierName": "Verizon"
, "link": "http://www.verizonwireless.com"
, "wireless": true
}

Note that the country parameter is ignored. Only US numbers are supported at this time.

Also note that carrier, link, and wireless may be empty strings or undefined.

Update the Database

This tool is used to scrape the nanp nxx database used by tel-carrier

Here's the process:

#1 Installation

git clone [email protected]:coolaj86/nxx-lookup.git
pushd nxx-lookup
npm install --dev

#2 Download the database

node ./download

This will download to ./data which will result in about 80MiB of html files.

When the download completes it will write out about 5MiB of tables into data.json.

That file is an object that looks like this:

{ list: {
    "801": [
      [360,1531,39,39,908,4]
    , ...
    ]
  , ...
  }
, cities: [ "DALLAS", ... ]
, states: [ "Texas", ...]
, sts: [ "TX", ... ]
, companies: [ "CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX", ... ]
, types: [ "WIRELESS PROV", ... ]
, carriers: [ "verizon", ... ]
, links: [ "http://www.verizonwireless.com", ... ]
}

The array inside of list is in the following format:

{ "area code": [ ["prefix", "city", "state", "st", "comment", "type"] ] }

Note that what may appear to be numeric ids used for city, state, st, comment, and type are actually transient and you must not rely on them - they're just for the sake of poor-man's compression.

Porting

No porting information is available at this time.

In the future we may maintain a list of known-ported numbers to exclude from the nxx blocks. Don't count on it.
