Also converts between the formats: paste a Place ID to get the CID, or a Feature ID to get the Place ID. Try an example
- ChIJ…Place ID — for the Places API, Maps URLs and the classic review link.
- 0x…:0x…Feature ID — inside every Google Maps link of a business (after !1s).
- 123…CID — the customer ID, the decimal form of the second half of the Feature ID.
About the Google Place ID Finder
The Google Place ID Finder reads every identifier of a Google Maps listing: the Place ID (ChIJ…), the CID (customer ID) and the Feature ID (0x…:0x…) — from a normal Maps link, the short share link of the Maps app, a review link or one of the IDs themselves. It also builds the links that follow from them: review form, Maps listing and directions.
Google's own Place ID finder needs a map search and the Places API; here a link is enough, because a ChIJ Place ID is just an encoded form of the Feature ID. For a ready-to-share review link with QR code, use the Google Review Link Generator; for structured data with your Maps link in hasMap, the LocalBusiness Schema Generator.
A text identifier such as ChIJN1t_tDeuEmsRUsoyG83frY4 that names one place in Google's database. The Places API, the official Maps URLs and the classic review link all use it. Business listings have IDs starting with ChIJ; IDs starting with Ei or Gh usually belong to addresses, streets or plus codes.
The customer ID (also called ludocid) is a 64-bit number for a business listing. maps.google.com/?cid=… opens the listing, and the g.page review short link is nothing but the CID in encoded form. It is the second half of the Feature ID, converted from hexadecimal to decimal.
A ChIJ Place ID is a Base64-encoded structure that contains both halves of the Feature ID from the Google Maps link. The tool decodes and encodes this structure directly — checked against Google's own published example (the Sydney office, ChIJN1t_tDeuEmsRUsoyG83frY4 ↔ CID 10281119596374313554). No Google API is called.
Yes. Google notes that Place IDs can change over time, for example when a business moves or listings are merged, and recommends refreshing stored IDs that are older than twelve months. Before you print a review link, test it once.
The CID is only the second half of the Feature ID. The first half — a location component — cannot be reconstructed from it. Paste the full Google Maps link of the listing instead; the share link from the Maps app works too.
No. The conversion happens in memory for this one request. Only short links (maps.app.goo.gl, share.google, goo.gl/maps, g.page) are sent to Google's redirect service to read where they point.
