title: Check if an address is within an area map
body: <p>The need I have is that a user (client) can put his/her address and to validate if it is within our delivery area.</p>
  
  <p>Currently I have designed this layer on google maps:</p>
  
  <p><a href="https://www.google.com/maps/d/u/0/viewer?mid=1E3bcIm6Dy4icmTA4S-hEqOZeHpU" rel="noreferrer">https://www.google.com/maps/d/u/0/viewer?mid=1E3bcIm6Dy4icmTA4S-hEqOZeHpU</a></p>
  
  <p>What is the technology that I use?</p>
  
  <p>I just need an input text of a formulary to write the address and respond with an OK or a sorry.</p>
  
  <p>All the information that I find are questions and solutions to calculate routes and only need to verify an address within an area.</p>
  
  <p>Now I know as autofill and get save the address to verify. Now I just need to know how I can verify that direction in my area.</p>
