How to Find a Booking.com Hotel ID (3 Ways, With Examples)

Every property on Booking.com has a numeric hotel ID.
It's how Booking.com's own systems, and any API working with Booking.com data, identify a specific property.
You need it for review extraction, price monitoring, and data pipelines; if you searched for a Booking.com hotel ID finder, this page is that, in three methods.
The catch: unlike TripAdvisor, Booking.com never prints the ID in the URL.

Method 1: Read the Hotel ID From the Page Source

First, what the URL does and doesn't tell you:

https://www.booking.com/hotel/th/baan-coconut.html

The numeric ID lives in the page's HTML instead.
On a typical property page it appears over 100 times, so it's easy to find once you know what to search for:
1. Open the property page on Booking.com.
2. View the page source: Cmd+U on Mac, Ctrl+U on Windows (or right-click and pick "View Page Source").
3. Search for b_hotel_id. The number next to it is the hotel ID.
For Baan Coconut, the source contains b_hotel_id: '1302021', so the hotel ID is 1302021.
The same number also appears in data-hotel-id="1302021" attributes throughout the page, if you prefer searching for that.
This works for any public listing, no login required.

Method 2: Convert the URL With an API

When you're working in code, or you have a hotel name instead of a URL, an API lookup beats view-source.
StayAPI's Booking.com URL-to-ID endpoint takes the country/slug segment of the listing URL and returns the numeric ID:

curl -X GET "https://api.stayapi.com/v1/booking/hotel/url-to-id?url=th/baan-coconut" \
  -H "x-api-key: YOUR_API_KEY"

{
  "hotel_id": "1302021",
  "url": "https://www.booking.com/hotel/th/baan-coconut.html"
}

The url parameter is the part after /hotel/ in the listing URL: th/baan-coconut here.
One split() on the URL you already have produces it.
Starting from a hotel name with no URL at all?
The meta match endpoint resolves a name like "Baan Coconut Phuket" to its canonical Booking.com URL, which you then feed into URL-to-ID.
Sign up at stayapi.com to get an API key. Free tier, no credit card.
For a one-off lookup with no code, the free Booking.com hotel details tool takes the full listing URL in the browser.

Method 3: Bulk Lookup for a Hotel List

The scenario: 50-500 hotel names or URLs in a spreadsheet, and you need the Booking.com hotel ID for each.
View-source stops scaling at around 10 properties.
The workflow, no code required:
1. Put your hotel names or URLs in a Google Sheet, one per row.
2. Build an N8N or Make.com flow: for each row, resolve the name to a URL with meta match (skip this step if you already have URLs).
3. Send the URL's country/slug segment to the URL-to-ID endpoint.
4. Write hotel_id back to the row.
Starting from URLs, each hotel costs 1 request; starting from names, 2.
For very large lists (1,000+), run the flow overnight rather than firing everything at once.

What You Can Do With a Hotel ID

Once you have the ID, the rest of the Booking.com data API surface takes it as input:

The most common next step is pulling Booking.com reviews programmatically: the hotel ID is the one required parameter of the hotel reviews endpoint.
Comp-set work follows the same pattern: collect the IDs for your competitor set once, then track their prices and review scores on a schedule.

FAQ

What is a Booking.com hotel ID?

A unique numeric identifier Booking.com assigns to every property on the platform.
It doesn't appear in the listing URL; it lives in the page source and in API responses.

Is the hotel ID the same as the property ID in the extranet?

Booking.com shows partners a property ID inside the extranet after login.
For any public listing, including your own, the page-source method in this guide gets you the numeric ID without logging in.

Is the hotel ID the same as my booking confirmation number?

No.
A confirmation number identifies one reservation and comes in your booking email.
The hotel ID identifies the property itself, for every guest and every date.

Do Booking.com hotel IDs change?

Rarely.
IDs are stable unless a listing is removed and re-created, for example after an ownership change where the new owner lists the property fresh.

How do I find hotel IDs for hundreds of hotels at once?

Feed names or URLs through a lookup API in a loop, as in Method 3.
A spreadsheet plus an N8N flow handles it without code, and each hotel resolves in 1-2 requests.
