To add a call extension in Google Ads with Claude or ChatGPT, connect your Google Ads account to PaidSync.ai and ask the assistant to add a phone number to a campaign, which lets people call you straight from the ad. You give the campaign, the phone number and the country. PaidSync.ai returns the call extension as a preview before it is added.

Which Tools Do the Work

A call extension adds your phone number to a search ad, so mobile users can tap to call. Two tools handle it, depending on whether you want the number as a reusable asset:

add_call_extension and create_call_asset change it.

How the Workflow Is Built

ToolWhat it does
add_call_extensionAttaches your phone number to the campaign
create_call_assetCreates a reusable phone number asset

The country code matters. The tool defaults to US, so a number from the UAE, Spain or the UK needs its own code or Google may reject it. Use the number in the same format on your landing page, because mismatched numbers are a common source of review delays.

How to Add a Call Extension in Google Ads With Claude in 5 Steps

These steps use Claude to add a call extension. PaidSync.ai also works in ChatGPT, and the prompts are the same.

1

Connect Google Ads to PaidSync.ai

Start at paidsync.ai, then link Google Ads through Google's own sign-in screen. No developer token and no Google Cloud project are involved. The login you choose must reach the account where you will add a call extension.

2

Add PaidSync.ai to Claude

Install PaidSync.ai from Claude's connector directory and sign in. Ask "list my Google Ads accounts" and select the account to add a call extension in.

3

Pick the campaign

Ask "List my campaigns" and choose the one that should show the number. A call extension belongs on campaigns where a phone call is a real goal.

4

Give the number and country

Tell the assistant the phone number and its country, for example +34 and ES. Ask it to run add_call_extension on the campaign.

5

Check the preview

The assistant returns a preview with the number and the campaign. Approve it, then ask for the campaign extensions to confirm the call extension is attached.

How to Check the Result

Read the campaign extensions again and check the number matches the one on your site. If calls are a goal, track them as a conversion so you can compare them with clicks.

Use these two prompts to add a call extension, in this order.

"Add the phone number +34 910 000 000, country ES, as a call extension on my Brand Search campaign."
Comes back as a preview before it is applied.
"Create a call asset for +44 20 7946 0000 with country code GB."
Comes back as a preview before it is applied.
