An MLS, or multiple listing service, is a database used for real estate transactions. Real estate agents and brokers often add MLS searches to their sites to let visitors find listings in their area.

If you're in the real estate business, you can add an MLS search to your site using some custom code.

Note: To add MLS search to your site, you should be a member of an IDX service. Some IDX services include Diverse Solutions, IDXBroker, and Displet.

The steps in this guide include adding advanced code to a code block, which is available in the Core, Plus, Advanced, Business, Commerce Basic, and Commerce Advanced plans. To learn more, visit Choosing the right Squarespace plan.

Step 1 - Add a code block

Click Edit on the page or post where you'd like your search to appear. Click an insert point and select Code from the menu.

For more detailed steps, visit Adding content with blocks.

Step 2 - Paste the MLS code

Most IDX services provide HTML embed code for adding MLS search to your site. Find and copy this code from your IDX service and paste it into the code block.

Keep in mind, the code may not render when you're logged in to your site. Here's an example of how an MLS search could appear:

Some IDX services may require additional code that you'll need to add to code injection.
