Google Maps CID Extractor
Pull the CID (Ludocid) and FID out of any Google Maps link to build direct-to-listing URLs and reinforce your Maps presence. Ultra-easy keyword, same tool surface as the Place ID finder.
What is a Google Maps CID?
A Google Maps CID (short for customer ID or client ID, and also called the ludocid) is the numeric identifier Google assigns to a specific business listing. Every verified place on Google Maps carries one, and it stays the same even when the business name, address, or category changes. When you see a long string of digits inside a Maps link, that is usually the CID pointing straight to one listing. To find the google maps cid, you open the listing, copy the full Maps URL, and paste it into a CID extractor like this one. The tool reads the link, pulls out the CID and the feature ID (FID), and hands you a clean number you can drop into a direct listing link such as https://maps.google.com/?cid=NUMBER.
How do you extract the Google Maps CID from a link?
You extract a google maps cid by copying the full share URL from a listing and letting a cid extractor parse out the numeric ID and the feature ID for you. The whole process takes under a minute and does not require any code, a Google account, or an API key. Follow the steps below and you will have a usable CID and a working direct link.
- Open the business listing on Google Maps in your browser. Search for the name plus the city, then click the result so the panel expands on the left.
- Copy the Maps URL from the address bar, or use the Share button and copy the link it gives you. The full URL is what carries the identifiers, so grab the whole thing.
- Paste the google maps link into the extractor field above and run it. The tool decodes the URL and separates each identifier it can read.
- Read the CID and the FID from the results. The CID is the long decimal number. The FID looks like two hex chunks joined by a colon, for example 0x89c25a1b1cebf6cf:0x7a9f1c2d3e4b5a6f.
- Build your direct URL by placing the CID after the cid parameter, giving you https://maps.google.com/?cid=NUMBER. That link opens the exact listing every time.
- Save the CID alongside the business name and address in your notes or spreadsheet so you can reuse it for review links, citations, and audits later.
If the extractor cannot find an identifier, the culprit is almost always the link itself rather than the tool. Shortened links, links copied before the page finished loading, and links grabbed from a mobile app share sheet sometimes drop the data segment that carries the identifiers. When that happens, open the listing again in a desktop browser, wait for the left panel to fully render, and copy the URL straight from the address bar. That full URL contains everything the parser needs, and it resolves nearly every empty-result case in one try.
Why does the Google Maps CID matter for local SEO?
The google maps cid matters because it gives you a stable, unambiguous pointer to one listing that will not rot the way a shortened link can. Business names get rebranded, addresses move, and Google sometimes rewrites its URL formats, but the CID keeps resolving to the same place. That reliability is exactly what you want when you are building assets that need to last, like citations across dozens of directories or a review link printed on a receipt.
It also solves the disambiguation problem. Plenty of businesses share a name, and a plain text search can surface the wrong branch or a competitor with a near-identical brand. When you hand a customer, a directory, or a citation service a link built on the CID, there is no guessing which listing you mean. The identifier locks the reference to one place, which protects your review flow and keeps your NAP data pointing where it should.
For agencies and in-house teams, the CID becomes a small but powerful key in your record-keeping. You can store one number per client location and use it to rebuild review links, verify the correct listing during an audit, or feed a lookup that confirms the place is still live. That consistency saves time and cuts the risk of sending traffic or reviews to the wrong listing.
There is a reputation angle too. Reviews are one of the strongest local ranking and conversion signals, and every extra review you collect is worth more when it lands on the right listing. A direct review link built on stable identifiers removes the friction of asking a customer to search, scroll, and find your business among lookalikes. Fewer steps means more completed reviews, and more completed reviews on the correct listing compound into a stronger Maps presence over time. The identifier is the quiet plumbing that makes that flow dependable.
It also future-proofs the assets you hand to third parties. When you submit a listing to a directory, embed a review button on your site, or print a QR code on packaging, you are committing to a link that may live for years. If that link is a fragile search query or a shortened redirect, a single Google URL change can break it silently, and you may not notice until reviews stop arriving. Anchoring those assets to the numeric identifier gives you a link you can trust to keep resolving, which is exactly the kind of durable foundation local SEO rewards.
Understanding the IDs this tool extracts
This tool reads a Maps URL and pulls out the two identifiers Google embeds in it, then shows you how they relate to the Place ID you may already know from the API world. Here is what each one means and how to use it.
The CID (Ludocid)
The CID is a plain decimal number that Google uses to reference one business listing. You will sometimes see it labeled ludocid inside older link formats, which is why a good cid extractor looks for both spellings. Because it is just a number, it drops cleanly into a direct link like https://maps.google.com/?cid=NUMBER, and that link reliably opens the listing on Maps.
The FID (Feature ID)
The feature id (FID) is Google's internal reference for a map feature, and it appears in hex form as two chunks joined by a colon, such as 0x89c25a1b1cebf6cf:0x7a9f1c2d3e4b5a6f. The second chunk is the same value as the CID, just written in hexadecimal instead of decimal. That relationship is why converting between the FID and the CID is a simple base change rather than a lookup.
How they relate to the Place ID
The place id is a separate identifier that Google's Places API uses, and it usually starts with the prefix ChI. It is not the same as the CID, and you cannot swap one for the other in a link that expects the other format. A place id powers API calls and the standard direct review link, while the CID powers the maps.google.com/?cid= link. Knowing which one a given tool or endpoint wants saves a lot of confusion.
Hex versus decimal forms
The single biggest source of mistakes here is mixing up the hex and decimal forms of the same value. The FID's second segment is hex; the CID is that segment converted to decimal. If a link or a review flow rejects your number, check whether you pasted the hex chunk where a decimal CID was expected, or the other way around. The extractor shows both so you never have to guess.
A quick way to sanity-check yourself: a hex value can contain the letters a through f and the prefix 0x, while a pure decimal CID is nothing but digits. If you see any letters in a value you meant to use as a CID, you are still holding the hex form and need to convert it first. Keeping that one rule in mind catches the majority of broken links before they ever get published, and it is the reason this tool surfaces both representations side by side rather than making you pick.
Best practices and common mistakes
A few simple habits keep your extractions clean and your links working. Watch these and you will avoid the errors that trip up most people the first time they pull a CID.
- Use the full share URL, not a trimmed fragment. The identifiers live in the long data segment of the link, so a chopped URL often loses the FID and the CID entirely.
- Be careful with shortened goo.gl/maps links. They hide the real identifiers behind a redirect, so expand them in a browser first, then copy the resolved google maps link before you paste it in.
- Keep the decimal versus hex distinction straight. The CID is decimal, the FID is hex, and pasting one where the other belongs is the most common reason a direct link fails.
- Do not confuse the CID with the place id. They are different identifiers with different link formats, and swapping them breaks both the maps link and the direct review link.
- Store the identifiers with the business name and address. A bare number is easy to misattribute later, so label every CID and FID you save with the listing it belongs to.
- Verify the direct link before you publish it. Paste your finished maps.google.com/?cid= URL into a fresh browser tab and confirm it opens the exact listing you intended.
When should you use a Google Maps CID?
You reach for a CID whenever you need a rock-solid pointer to one listing, and there are several everyday situations where it beats a plain search link. Below are the scenarios where extracting the identifier pays off most.
- Building a review link. Pair the listing's place id with https://search.google.com/local/writereview?placeid=PLACE_ID to send customers straight to the review box, and keep the CID on file to rebuild or verify that direct review link later.
- Managing citations. Directories and NAP listings stay consistent when you point them at a stable identifier, so a CID-based link prevents the drift that shortened or search-based links cause over time.
- Running agency audits. When you check a client's listing, the CID confirms you are looking at the correct place and not a duplicate or a similarly named competitor across town.
- Doing API lookups. If you work with the Places API, the FID and CID help you cross-reference a listing, and you can map them back to the place id the API expects for programmatic queries.
- Cleaning up duplicate listings. When a location has accidental duplicates or a merged history, comparing the CID of each result tells you which listing is the live, verified one and which are stale copies you should ask Google to remove.
- Documenting client handoffs. When you onboard or transfer a client, recording the CID for every location gives the next person an unambiguous reference that survives rebrands, so nobody has to re-hunt the correct listing from scratch.
Across all of these, the common thread is precision. Local SEO is full of near-duplicate names, moved locations, and lookalike competitors, and a single wrong link can quietly leak reviews or citations to the wrong place for months. Pulling the identifier once and reusing it everywhere is a small habit that removes an entire class of avoidable errors, which is why experienced local marketers keep a CID on file for every location they manage.
Frequently asked questions
Is the Google Maps CID the same as the Place ID?
No. The CID is a decimal number used in maps.google.com/?cid= links, while the place id is a longer string that usually starts with ChI and powers the Places API and the standard direct review link. They point to the same business but are not interchangeable in a URL, so use the format each endpoint expects.
How do I turn a Google Maps CID into a working link?
Take the decimal CID from the extractor and place it after the cid parameter, producing https://maps.google.com/?cid=NUMBER. Paste that into a browser to confirm it opens the right listing. This link stays valid even if the business name or address changes, which makes it ideal for citations and long-lived references.
What is the ludocid and how is it different from the CID?
Ludocid is simply the label Google has used for the CID inside certain link formats, so they refer to the same numeric identifier. A good cid extractor recognizes both terms and returns the same value regardless of which spelling the source URL uses, so you do not need to treat them as two separate things.
Why does the FID look like hexadecimal?
The feature id (FID) is stored in hex as two chunks joined by a colon, such as 0x89c25a:0x7a9f1c. The second chunk is the CID written in hexadecimal, so converting it to decimal gives you the number you use in a direct link. That is why the FID and the CID are two views of one underlying value.
Do I need an API key to extract a CID?
No. Extraction only reads the identifiers already present in the Maps URL you paste, so no key, login, or paid quota is involved. An API key becomes relevant only if you later use the place id for programmatic Places API calls, which is a separate step from pulling the CID out of a link.
Can I get a direct review link from the CID alone?
The cleanest direct review link uses the place id in https://search.google.com/local/writereview?placeid=PLACE_ID, not the CID directly. Keep the CID to open and verify the listing, then obtain the matching place id when you need the review URL. Storing both identifiers together makes rebuilding either link fast and error-free.
