# Suburbs and Postcodes

****Marlin GTX**** enables users to add, edit or delete suburb and postcode entries [wherever customer information can be edited](/gtx/docs/suburbs-and-postcodes#customer-maintenance).

Suburbs and postcodes can also be managed using the [Postcodes Maintenance](/gtx/docs/suburbs-and-postcodes#postcode-maintenance) module.

## Customer Maintenance

Suburbs and postcodes can be added and edited **wherever customer information can be edited** (e.g. Work Orders, Invoices, Customer Maintenance).

Click the **Magnifying Glass** in either the **Suburb** or **Postcode** field.

**To add a new entry:**

- Press the **Insert** key on the keyboard
- The **Create Postcode** pop-up will open:
  - **Enter** the required details
  - Click **Save**

You can also edit existing suburb information by selecting it and pressing **Ctrl+E** on the keyboard.

Suburbs and Postcodes can be [deleted](/gtx/docs/suburbs-and-postcodes#deleting-postcodes) by selecting them and pressing the **Delete** button.

          Note

          

Regardless of whether the suburb is entered via the **Suburb** or **Postcode** field, both will be created when the Save button is clicked.

## Postcode Maintenance

Suburb and postcode information can also be added and edited, independent of customers, using the **Postcode Maintenance** module.

**To access the module:**

- Select **System > System Files > Places > Postcodes** from the menu bar

The **Postcodes Maintenance** module will open, showing a list of active suburbs and postcodes within your GTX system.

**To edit existing postcode information:**

- **Select** it in the list
- Click on the **Edit** button at the top of the module window

**To add a new postcode/suburb:**

- Click on the **Add** button at the top of the module window
- The **Add Postcode** window will open.
  - **Enter** the required information
  - Click **Save**

          Warning

          

You cannot edit a **Suburb** name or **Postcode**:

- To change either value, the suburb must be **deleted** and re-added.

## Deleting Postcodes

Postcodes and suburbs **cannot be deleted using the Postcode Maintenance module**.

**To delete a postcode/suburb:**

- Wherever a **customer can be edited**:
  - Click on either the **Suburb** or **Postcode** picker
  - Highlight the suburb/postcode (arrow keys/type to search)
  - Press **Delete** on the keyboard

**The Delete Postcode pop-up will open:**

- **Make sure** you want to delete the suburb/postcode
- To delete it, click **Save**
