Free SEO Tool
Free Google CID Finder
Find the CID (ludocid) of any Google Business Profile — paste a Google Maps URL, get the CID number and ready-to-use links. Free, no signup, runs in your browser.
How to get the URL: open the business on google.com/maps, click its listing, then copy the full URL from your browser's address bar.
Paste a Google Maps URL on the left — the CID appears here instantly. Nothing is sent to a server.
How to find a Google Business Profile CID
- Open the business on Google Maps — go to google.com/maps, search the business name, and click its listing.
- Copy the full URL from your browser's address bar (not the short "share" link — see the FAQ if you only have a maps.app.goo.gl link).
- Paste it above. The tool decodes the CID from the URL and builds the Maps and knowledge-panel links for you.
What a CID is — and why local SEOs use it
The CID (Customer ID, also seen as the ludocid URL parameter) is the permanent numeric ID Google assigns to every Business Profile. Unlike the business name or address, it never changes, which makes it the reliable way to reference a listing: https://maps.google.com/?cid=YOURCID always opens that exact profile. Local SEOs use CID links for citation building, review management, client reporting and rank tracking — and to confirm which of several similar listings Google actually treats as the entity. The CID hides inside every Google Maps URL as a hexadecimal value; this tool decodes it in your browser.
Frequently asked questions
What is a Google CID?
A CID (Customer ID) is the permanent numeric ID Google assigns to every Google Business Profile / Maps listing. It uniquely identifies the listing regardless of name changes, and it powers direct links like https://maps.google.com/?cid=YOURCID.
What is ludocid?
Ludocid is the same CID number used as a URL parameter in Google Search (…&ludocid=YOURCID). Adding it to a search URL forces Google to show that exact business's knowledge panel — useful for review links and local SEO audits.
How do I find the CID for a business?
Open the business on Google Maps (google.com/maps, search the name and click the listing), copy the full URL from your browser's address bar, and paste it into this tool. The CID is encoded in the URL as a hex value — the tool decodes it to the decimal CID instantly.
Is the CID the same as the Place ID?
No. The Place ID (starts with "ChIJ…") is a separate identifier used by Google's APIs, and it can change. The CID is the stable numeric ID behind the listing. This tool extracts CIDs; Place IDs can't be converted to CIDs without an API lookup.
Does a business's CID ever change?
Effectively no — the CID stays with the listing for its lifetime, which is why local SEOs use it for tracking, citations and direct links. It only changes if the listing itself is deleted and recreated.
Why does my short maps.app.goo.gl link not work?
Short share links don't contain the CID data. Open the short link in your browser first, let the full Google Maps page load, then copy the long URL from the address bar and paste that here. Everything runs in your browser — nothing is sent to a server.
