Note: This plugin requires Sweep&Go Core plugin.

Installation: 

• Install and Activate the Sweep&Go Core Plugin

• Navigate to WP Admin → Sweep&Go Core → Add-ons and install the SNG Map Builder.

SNG Map Builder lets you instantly generate Google Maps overlays that highlight your service area ZIP code boundaries. Enter a city name, paste in your ZIP codes, and the plugin handles everything else: fetching boundary data, building the map, and giving you a URL or iFrame code you can drop anywhere on your site.

How it works

Add a city and its ZIP codes in the WordPress admin. The plugin pulls boundary data from the US Census Bureau TIGER API (free — no extra API costs) and renders shaded polygon overlays using the Google Maps JavaScript API. Your map is saved as a standalone file and is ready to be embedded the moment generation completes.

Key features

• Instant generation - enter a city and ZIP codes, click generate, and your map is live in seconds

• One-click embed - copy the direct URL or a ready-to-paste iFrame code with a single click

• Edit & regenerate - update a city's name or ZIP codes at any time; the map rebuilds automatically

• Custom boundary color - choose any hex color for the ZIP code overlay to match your brand

• Cache-safe - regenerated maps always load fresh, no browser caching issues

• Free boundary data - ZIP code boundaries are sourced from the US Census Bureau, so there are no additional data costs beyond your Google API key

Beneftis

• Instantly Visualize Service Areas - Turn boring ZIP code lists into clean, interactive maps your customers actually understand. Help visitors quickly see if you serve their area — increasing trust and conversions.

• Save Hours of Manual Work - No more drawing maps or embedding complicated tools. Just enter ZIP codes and generate a fully functional map in seconds.

• Easy Embeds Anywhere - Drop your map into any page, post, or landing page with a simple embed. Works perfectly with builders like Elementor, Gutenberg, or custom themes.

Showcase your service areas with interactive, embeddable maps, no coding required.
