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:
- Open Google Maps and locate the target business profile.
- Click the Share button and copy the provided link (e.g.,
https://maps.app.goo.gl/9ZpL9vW...). - Head over to MapsCIDFinder.com and paste the link into the URL input box.
- 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:
- Open the target business listing in desktop Google Chrome.
- Right-click anywhere on the profile page and select View Page Source (or press
Ctrl + U/Cmd + Option + U). - Open the page search bar with
Ctrl + F(orCmd + F). - Search for the term
ludocid\\x3dor simplyludocid. - Directly following this parameter, you will find the 19-digit or 20-digit integer. That is the permanent CID number!
...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
