Google forwarding numbers explained

What is a Google forwarding number?

A Google forwarding number is a number owned by Google that stands in for your business number, so Google can see that a call happened and how long it lasted.

When someone dials it, Google connects them to the number you entered in Google Ads. Your phone rings as normal and the caller usually hears nothing different. Google's call reporting help explains where these numbers are used. In the UK they are local or national numbers assigned from Google's own range, not your number.

Where does Google use forwarding numbers?

Google uses them in two places.

The website version is set up under calls to a phone number on your website. It needs the Google tag on every page and a snippet that swaps your number.

What are the limits of Google forwarding numbers?

Forwarding numbers are free and easy, but they only answer one question: did a call happen from Google?

• No recordings or transcripts, so you cannot hear whether the call was a real enquiry.
• Only Google Ads visitors get them, so you cannot compare against SEO, social or print in one report.
• Numbers are temporary and change, so a customer who saves the number may later ring one that no longer reaches you.
• Counting rules are limited to duration, with no lead labelling or per-call value.
• Availability varies by country and Google can stop showing them for a given ad.

These limits are the main reason Google's figures and your real enquiries differ — see why Google Ads calls do not match real enquiries.

How do your own tracking numbers compare?

Your own numbers stay yours and carry more evidence per call.

Should I use Google forwarding numbers or my own?

Use Google forwarding numbers if you only run Google Ads, only need call counts and do not want to manage numbers. Use your own tracking numbers if you want recordings, need to compare channels, manage clients as an agency, or want Google to learn from qualified calls only.

You can combine them. Keep call reporting on in call assets for calls straight from the ad, and use Call Bullet numbers on the website. Just make sure the website snippet from Google is removed so the two scripts do not fight over the number on the page.

How do I switch from Google's website snippet to Call Bullet?

Switching takes one short session.

1. Buy a small website pool of UK numbers in Call Bullet with the area code you want.
2. Install the Call Bullet swap script or WordPress plugin on every page.
3. Remove Google's website call number replacement snippet from your tag setup.
4. Connect Google Ads in Call Bullet and run the validation check.
5. In Google Ads, set the old website call action to secondary and the Call Bullet import action to primary.
6. Check after a week that website calls now appear once, with recordings, in both tools.

Read GCLID call tracking for how the click is matched, and calls from ads vs calls from website for keeping both routes clean.

Do forwarding numbers affect my local SEO?

Google forwarding numbers only show to ad visitors, so they do not change the number search engines see on your page. Call Bullet works the same way: the swap script changes the number in the visitor's browser while your main number stays in the page source and in your Google Business Profile, so your name, address and phone details stay consistent.

What happens to calls when a forwarding number changes?

Google reassigns forwarding numbers over time, so a number shown in an ad last month may not reach you next month.

For most callers this does not matter, because they ring straight from the ad. It matters for people who save the number, write it down or call back days later from their phone's history. If that number has since been reassigned or retired, the call may not reach your business at all.

Your own tracking numbers avoid this. A Call Bullet number stays assigned to your workspace for as long as you keep it, so a customer who saved it in March can still reach you in October. Website pool numbers are recycled between visitors, but they always forward to your business. If you stop using a pool number, it is held back from reuse for a period so stray callbacks still connect. For print, vans and directories, use a fixed number so the published number never changes.

Can I keep my main number on Google Business Profile?

Yes. Your Google Business Profile should keep your main business number as its primary number, because that number is part of your consistent business listing across the web.

If you want to measure calls from the profile, Google lets you add a tracking number as the primary number and move your main number to an additional number, so the listing still matches. Call Bullet's fixed numbers suit this, and you can publish and check them from the Numbers page. Read call tracking for Google Business Profile for the full approach. Ads, the website and the profile then each have a clean source, and your reports separate paid calls from the free calls your profile already earns.
