Google hides the permanent Customer ID (ludocid) deep inside internal script tags. Here are the 3 proven ways to extract any business CID number in seconds—from automated one-click tools to manual source code inspection.

Why Doesn't Google Display the CID Number Directly?

When you open a business on Google Maps, the address bar displays a massive, temporary string of coordinates and session tokens (e.g., @41.0082,28.9784,17z/data=!4m6!3m5!1s0x...).

Google deliberately minimizes technical parameters for regular consumers. However, for SEO agencies, web developers, and multi-location franchises, obtaining the permanent CID is critical. Below are the three most reliable extraction methods.

Method 1: Use MapsCIDFinder (Instant, 1-Click)

The fastest and most reliable method is to use our free automated decoder:

  1. Open Google Maps and locate the target business profile.
  2. Click the Share button and copy the provided link (e.g., https://maps.app.goo.gl/9ZpL9vW...).
  3. Head over to MapsCIDFinder.com and paste the link into the URL input box.
  4. Click Resolve CID.

Our backend expands mobile redirects, extracts the permanent decimal CID, computes the 64-bit Hex value, identifies the Google Place ID, and formats ready-to-use review links and Schema tags instantly.

Method 2: Inspecting Google Maps Page Source (Manual)

If you prefer not to use an automated tool, you can locate the CID manually inside your browser's Developer Tools:

  1. Open the target business listing in desktop Google Chrome.
  2. Right-click anywhere on the profile page and select View Page Source (or press Ctrl + U / Cmd + Option + U).
  3. Open the page search bar with Ctrl + F (or Cmd + F).
  4. Search for the term ludocid\\x3d or simply ludocid.
  5. Directly following this parameter, you will find the 19-digit or 20-digit integer. That is the permanent CID number!
Source Code Match Example:

...ludocid\\x3d11401689387182079980#lrd\\x3d0x...

Method 3: Decoding the Hexadecimal Value in Embed URLs

When you click "Embed a map" on Google Maps, Google provides an <iframe> snippet containing a parameter starting with !1s0x.

This hexadecimal string represents the internal 64-bit entity ID. You can convert this hex string into decimal format using our Hex Converter Tool.

For instance:

  • Input Hex: 0x9e3af016c2543fec
  • Output Decimal: 11401689387182079980
