A hotel often has several identifiers: the Google Ads customer ID, Google Hotel Center account ID and an individual property or hotel ID. They are related to different objects, so copying the wrong number delays a link request.
The correct ID depends on the direction of the connection. When Google Ads initiates the link, it asks for the Hotel Center Account ID. When Hotel Center initiates the link, the operator supplies a Google Ads customer ID.

Know which ID belongs to which platform
A Google Ads customer ID identifies the advertiser account that manages campaigns, budgets and conversions. It normally appears as a ten-digit number formatted in three groups.
The Hotel Center account ID identifies the Hotel Center account containing the travel feed. A property ID identifies a particular hotel in that feed; it is not a substitute for the account ID.
Practical checklist
- Write down the Google Ads customer ID and account name.
- Write down the Hotel Center account ID and owner name.
- Identify the correct hotel property IDs if linking only a subset.
Find the Google Ads customer ID
Sign in to the intended Google Ads account and inspect the account header or account selector for the customer ID. Check that you are not looking at the manager account when the Hotel campaign will run in a client account.
If a marketing agency handles several hotels, record the Ads ID next to the hotel's legal or trading name. Avoid sending screenshots that expose unrelated accounts.
Practical checklist
- Select the advertiser account, not the umbrella manager by mistake.
- Copy the ten-digit ID without altering digits.
- Verify you have admin permissions for the linking workflow.
Locate the Hotel Center account ID safely
Open the relevant Hotel Center account and check its account selector or account settings for the account identifier. Ask the Hotel Center owner or booking engine partner to confirm the ID if the interface does not expose it clearly.
A hotel can have a connectivity provider managing Hotel Center on its behalf. In that case, document the provider and approval contact rather than requesting passwords.
Practical checklist
- Confirm the identifier is the Hotel Center Account ID.
- Verify the property is actually listed in that account.
- Request permission-based approval instead of shared credentials.
Use the ID in the right linking direction
From Google Ads, open Tools → Data Manager → Google Hotel Center and enter the Hotel Center Account ID. An owner will then review the request inside Hotel Center.
From Hotel Center, open Account settings, initiate an account link using the Google Ads customer ID, choose properties and send. The Google Ads administrator approves the incoming request in Data Manager.
Practical checklist
- Document which account sent the request.
- Confirm the recipient sees the request.
- Check for Linked or Manage link status after approval.
Common mistakes to avoid
- Confusing a single property's hotel ID with the Hotel Center account ID.
- Linking a manager account when the hotel campaign needs a non-manager advertising account.
- Sharing login passwords instead of using Google's approval flow.
Frequently asked questions
Is a Google Ads customer ID the same as a Hotel Center Account ID?
No. They identify different Google products and are entered in different directions of the linking process.
Can the Hotel Center owner approve a request without using the agency's Google Ads login?
Yes. The Google Ads user sends the request and the Hotel Center owner reviews it in their own Hotel Center account.
