StreetAddress

Parses a US street address string and returns a normalized Address object. Returns nil when the string is not a recognized US address format.

This is a port of the Perl module Geo::StreetAddress::US originally written by Schuyler D. Erle.

Ruby Version

Requires Ruby 3.3 or later. For Ruby 2.x support, use gem version 1.0.6.

Installation

gem install StreetAddress

then in your code

require 'street_address'

or in your Gemfile

gem 'StreetAddress', require: 'street_address'

Basic Usage

require 'street_address'

address = StreetAddress::US.parse("1600 Pennsylvania Ave, Washington, DC, 20500")
address.number      # "1600"
address.street      # "Pennsylvania"
address.street_type # "Ave"
address.city        # "Washington"
address.state       # "DC"
address.state_name  # "District Of Columbia"
address.postal_code # "20500"
address.intersection? # false
address.to_s        # "1600 Pennsylvania Ave, Washington, DC 20500"
address.to_s(:line1) # "1600 Pennsylvania Ave"
address.to_s(:line2) # "Washington, DC 20500"
address.to_h        # { number: "1600", street: "Pennsylvania", ... }

address = StreetAddress::US.parse("1600 Pennsylvania Ave")
address.street # "Pennsylvania"
address.number # "1600"
address.state  # nil

ZIP+4 Support

address = StreetAddress::US.parse("5904 Richmond Hwy Ste 340 Alexandria VA 22303-1864")
address.postal_code     # "22303"
address.postal_code_ext # "1864"
address.full_postal_code # "22303-1864"

# Also works without the hyphen
address = StreetAddress::US.parse("5904 Richmond Hwy Ste 340 Alexandria VA 223031864")
address.postal_code_ext # "1864"

Intersection Parsing

address = StreetAddress::US.parse("Hollywood Blvd and Vine St, Los Angeles, CA")
address.intersection? # true
address.street        # "Hollywood"
address.street_type   # "Blvd"
address.street2       # "Vine"
address.street_type2  # "St"

Stricter Parsing

address = StreetAddress::US.parse_address("1600 Pennsylvania Avenue")
# nil - not enough information to be a full address

address = StreetAddress::US.parse_address("1600 Pennsylvania Ave, Washington, DC, 20500")
# Returns Address object - full address provided
