# Catch Postcodes from a specific Suburb or City only

In some countries like Australia, the same postcode numbers may be found in different suburbs. So, if you want to catch the postcodes corresponding to a particular suburb, the best way to do it is by specifying the key `city` (suburb) and `postcode`. 

As in: 
`city:SuburbName|postcode:####`

`city:Belmont|postcode:3216`
`city:Highton|postcode:3216`
`city:Wandana Heights|postcode:3216`

This will allow you to have a higher quality match and target, ensuring that the city/suburb has to match, and so does the postcode.

So, if you're looking to give different freights costs to different suburbs that share the same postcode, you can create different Regions, each with the specification (suburb + postcode), and add your desired Rates on each region to achieve it.
