In one sentence: a Google Place ID is the unique reference Google gives to a specific place — your shop, your clinic, your office — so that software can point at exactly that place and no other business with a similar name.
Think of it as a postcode for software. “The Red Lion, High Street” is ambiguous — there are hundreds. A Place ID is not. It is what the Google Maps Platform uses internally to fetch a place’s details, opening hours, location and reviews.
It looks like a long, meaningless string of characters, usually starting with ChIJ:
ChIJN1t_tDeuEmsRUsoyG83frY4There is no meaning encoded in it that you can read. It is not your business name, not your address, and not something you can guess or construct — you look it up.
Where you will be asked for one
Most small business owners never think about Place IDs until something asks for one. The usual suspects:
- Review tools and widgets that pull your Google reviews onto your website and want an unambiguous target.
- “Leave us a review” links — a widely used format is
search.google.com/local/writereview?placeid=…, which opens the review box for that exact place. - Embedded maps and store locators on a website, where a name search would risk pinning the wrong branch.
- Booking, CRM and listing-management platforms connecting to your Google presence.
- Multi-location businesses, where each branch needs its own identifier and names alone are hopeless.
Three ways to find yours
1. Google’s own Place ID Finder (easiest, free)
Google publishes a Place ID Finder in its Maps Platform documentation. Open it, type your business name and town into the search box, and click the result — the map pin displays the Place ID ready to copy. No API key, no account, no cost for a one-off lookup. Search for “Google Maps Platform Place ID Finder” and use the page on developers.google.com rather than a third-party clone.
2. The Places API (for developers)
If you are already working with the Maps Platform, a text search or find-place request returns the place_id for each match. This is the right route when you need Place IDs for dozens of locations at once, or when you want to re-check stored IDs on a schedule. It needs an API key and is billed under the usual Maps Platform terms.
3. Skip it — use a tool that takes your business name
Often the Place ID is only a means to an end. If what you actually want is a review link to hand to customers, our free Google review link and QR code generator builds it from your business name, with a print-ready poster download and no account. And if you want your reviews on your website, WeWidget connects the same way — search your name, pick a style, paste the embed.
A note on Maps URLs: it is tempting to dig a Place ID out of the long URL you get when you share your listing from Google Maps. Those URLs contain identifiers, but generally not the Place ID — you will usually be looking at hex strings or a CID instead. Copying one of those into a field expecting a Place ID is a common and confusing failure. Use the Place ID Finder.
Three things people mix it up with
A CID
An older, purely numeric identifier that appears in some Maps and Business Profile URLs. Same business, different system. Not accepted where a Place ID is expected.
Your Google Business Profile
The dashboard where you manage your listing — hours, photos, replies to reviews. That is the account you log into, not an identifier you paste into other software.
A Google Ads or Merchant account ID
Different products entirely. If a support article mentions a customer ID or merchant ID, it is not talking about the place your customers walk into.
The gotcha: Place IDs are not forever
This is the part that catches people out. Google documents that a Place ID can change over time and should not be treated as a permanent key — listings get merged, businesses relocate, and Google’s underlying data gets reorganised. Google’s own guidance is to refresh stored Place IDs periodically.
In practice, that means an integration set up two years ago with a hard-coded Place ID can quietly stop returning your reviews, and nobody notices until someone asks why the testimonials section on the website is empty. The failure is silent, which is what makes it expensive.
Two defences: prefer tools that resolve your business rather than making you store an ID by hand, and if you must store one, re-verify it occasionally instead of assuming it still points where it did.
You probably do not need to care about any of this
Place IDs are plumbing. WeWidget was built so you never touch them: search your business name, choose from 15+ widget styles, paste two lines into your site, and your live Google reviews appear — re-syncing from Google daily, with unlimited page views and no Google login. The rating badge is free forever, no card; full review widgets come with a 30-day free trial and start at £5/month. See your badge in ten seconds →
Where to go next
If you came here to build a review link, the Google review QR code guide takes it from link to printed poster. If you came here because reviews aren’t appearing where you expect, start with widget not showing — or, if they have vanished from Google itself, why Google reviews disappear. And if you are setting your listings up properly for the first time, our UK directories checklist is the wider job this is one small part of.
