parse-address-string

Extract street, city, state, zip, and country components from single-line address string

Example

var parseAddress = require('parse-address-string')

parseAddress('4296 W 7th St, Long Beach, CA 90802', function(err,addressObj){
	console.log('Street: ', addressObj.street_address1)
	console.log('City: ', addressObj.city)
	console.log('State: ', addressObj.state)
	console.log('Zip: ', addressObj.postal_code)
	console.log('Country: ', addressObj.country)
})

Notes

• This version currently targets US and Canada
  • Many other North American and European countries follow the same standard, but are not explicitly supported in this build
  • Updating lib/*.json would get you 90% of the way there
• explodeAddress conflates Street1 and Street2 as it is economically expensive to parse with high enough consistency
  • Would require a dictionary of prefix terms ("apt", "ste", etc) with heuristics to ensure it wasn't part of Street1
  • May add support for this in future versions
• Async callback format is for interoperability with potential future versions of this module, or if you wanted to swap it out with (for example) a call directly to google maps api

Api

parseAddress( addressString, callback )

addressString

callback(err, addressObj)

• err will always be false in current version, should still check if (err) for future compatibility
• addressObj has string or NULL properties street_address1, street_address2, city, state, postal_code, country

parseAddress.explodeAddress( addressString, callback )

Same as parseAddress()

parseAddress.implodeAddress( addressObject, callback)

Inverse of explodeAddress

addressObject - Object with some properties street_address1, street_address2, city, state, postal_code, country

callback(err, addressStr)

• err will always be false in current version, should still check if (err) for future compatibility
• addressStr Follows inline US/CA address format standard: Street1 Street2, City, State PostalCode, Country*
