What Is a Google Place ID? How to Find Yours (Free Guide)

Most people who search "place id" land on Google's own developer tool, copy a string that looks like ChIJN1t_tDeuEmsRUsoyG83frY4, and never find out what it actually does. It is not a tracking code and it is not your Google Business Profile URL. It is the one identifier that stays attached to a specific location even after everything else about the listing changes.

What Is a Google Place ID?

According to Google's own Places API documentation, a place ID is "a textual identifier that uniquely identifies a place" inside Google's database, with no fixed length or format. Place IDs exist for businesses, landmarks, parks, transit stations, and intersections, which is why the string you get for a coffee shop looks the same shape as the one for a train station.

The name, address, and phone number of a listing can all change without warning: a business rebrands, moves two doors down, or updates its hours. The place ID is Google's attempt to give developers and tools something more durable to key off than a name string that might read differently in every export.

Why You'd Actually Need One

Three situations come up repeatedly:

• Building a direct review link. Google's own, officially supported way to get a review link is through your Business Profile dashboard (Read reviews → Get more reviews), and it does not require a place ID at all. But if you manage review links for several locations at once, or you're embedding them in a review-management tool, the common technique is a URL built as https://search.google.com/local/writereview?placeid=YOUR_PLACE_ID: a pattern documented by review-platform vendors like ReviewTrackers, not something Google's help center itself publishes as the primary method.
• Calling the Places API. If you're integrating Google Maps data into your own app or CRM, most Places API requests (Place Details, Text Search, Nearby Search) take a place ID as the key parameter for pulling fresh details about one specific location.
• Matching records without relying on business names. If you're reconciling leads pulled from two different searches or two different tools, business names alone produce false matches ("Joe's Pizza" vs. "Joe's Pizza & Grill") and false negatives (the same business spelled two different ways). A place ID sidesteps that entirely, because it points to one specific listing regardless of how the name is formatted in either file. That's also the highest-priority match key MapsLeadExtractor's own import pipeline checks first before falling back to name and location. If that's the problem you're actually solving, the guide to merging CSV exports without creating duplicate leads covers it in more depth.

How to Find Your Google Place ID

Method 1: Google's official Place ID Finder (no account, no code)

Google publishes a free, interactive tool for exactly this on its Maps JavaScript API documentation. Type a business name or address into the search box, click the marker that appears on the map, and the place ID shows up in a panel below it. This is the same tool Google's own support community points people to when the question comes up.

Method 2: Pull it from a Places API response (for developers)

If you're already calling the Places API, Text Search and Nearby Search results include a place_id field on every result, and a Place Details request returns it as well. This is the more reliable path if you need place IDs for more than a handful of locations, since the Place ID Finder tool is built for one lookup at a time.

Place ID vs. CID vs. a Maps URL

Three different identifiers get confused constantly:

• Place ID is Google's internal, API-facing identifier (the alphanumeric string this guide is about).
• CID (Client ID / Customer ID) is an older, purely numeric identifier for a listing, sometimes visible in a Maps URL's parameters. It predates the modern Places API and some tools still use it, but Google's current documentation is built around place IDs.
• A Google Maps share link (the URL you get from the "Share" button on a listing) is neither of the above. It's a redirect URL, and extracting a usable place ID or CID from it usually requires opening the page and inspecting it rather than reading the link itself.

What to Know Before You Rely on One

Google's own documentation is explicit about three limits that matter if you're storing place IDs anywhere:

• Place IDs can change over time. Google's documentation states this directly: "Place IDs may change over time." A place ID you saved a year ago is not guaranteed to still resolve.
• The same location can have more than one place ID. Google's docs also confirm "it is possible for the same place or location to have multiple different place IDs," usually as a result of database updates or how a listing was originally indexed.
• Google recommends refreshing place IDs older than 12 months. A Place Details request using only the place ID field does this at no charge, according to Google's documentation.

In practice: a place ID is the best identifier available, but "best" isn't "permanent." Build any matching or deduplication logic with a fallback (name plus location is the usual one) for the cases where a stored place ID has gone stale.
