How to Find Your Google AdSense Publisher ID (pub-XXXXXXXX)
Your AdSense publisher ID (pub-XXXXXXXXXXXXXXXX) is hidden behind two clicks. Here's exactly where to find it — and what to do with it.
How to Find Your Google AdSense Publisher ID (pub-XXXXXXXX)
Every AdSense article assumes you already know your pub- ID. Most people don't. Here's the exact two-click path, plus the three places you'll actually use it.
The Exact Path
- Sign in at adsense.google.com.
- In the left menu, click Account.
- Click Settings → Account Information.
- Your Publisher ID is the value labelled 'Publisher ID', formatted pub-XXXXXXXXXXXXXXXX.
Where You'll Use It
- In ads.txt at your site root: google.com, pub-XXXXXXXXXXXXXXXX, DIRECT, f08c47fec0942fa0
- Inside the AdSense auto-ads script (the data-ad-client attribute).
- Anywhere a third-party platform (Shopify, Ghost, etc.) asks for your AdSense account ID.
Common Mistakes
- Copying with leading or trailing spaces — ads.txt parsers will reject it.
- Using your Google Ads customer ID (XXX-XXX-XXXX) instead of your AdSense pub- ID.
- Placing ads.txt anywhere other than the domain root.
Verify Your Setup
After updating ads.txt, visit https://yourdomain.com/ads.txt directly in a browser and confirm the line shows up exactly as written. Google's ads.txt crawler re-checks within 24 hours.

Open SEO AnalyzerFrequently Asked Questions
Is my publisher ID different from my customer ID?+
Yes. The customer ID is for Google Ads (advertiser side). The publisher ID (pub-XXXXXXXX) is for AdSense (publisher side). Don't mix them in ads.txt.
What if I can't see Account Information in AdSense?+
Your account might be pending review or limited. Check the home dashboard for any warning banner — the Settings menu unlocks once your account is fully active.
Can I have more than one publisher ID?+
No. Each AdSense account has exactly one publisher ID, which covers all the sites you add to that account.
Why does Google say my ads.txt is invalid?+
Most often a typo in the publisher ID, or hosting ads.txt at /folder/ads.txt instead of the root. It must be at https://yourdomain.com/ads.txt.
