Quick answer: Go to campaign Settings, open Locations, type your zip code plus state or country (example: `94103, California`), select the dropdown match, choose your targeting type, and save. Check performance in the geographic report after a few days.
What Is Zip Code Targeting in Google Ads?
Zip code targeting lets you show ads only to people in a specific postal area. One campaign, one neighborhood.
Why zip code targeting matters for local businesses
Local services, retailers, and real estate advertisers all benefit from tight geographic control. You stop spending budget on clicks from people who cannot use your business. You put spend where it actually converts.
How Google determines location (signals and accuracy)
Per Google's Ads Help Center, location targeting uses multiple signals: IP address, device GPS, Wi-Fi, Bluetooth, and cell tower data. Google also factors in interest-based location signals. Precision is high, but signal quality varies across devices and networks. Ads can occasionally reach users just outside your target boundary.
Zip Code Targeting Availability by Country
Not every country supports postal code targeting in Google Ads.
Which countries and regions support postal code targeting
Per Google Ads documentation, postal code is a supported location target type in several countries including the US and UK. Formats vary by country. A US example looks like `76622, US`. A UK example looks like `RM17, UK`. Other countries may use different formats or not support postal code targeting at all.
How to check if your target location is available
In the Locations section of campaign settings, type the postal code. If Google recognizes it, a dropdown match appears. No match means that postal code is not available as a target in your region. There is no separate lookup tool required.
Step-by-Step: How to Target Zip Codes in Google Ads
This takes about two minutes.
Navigate to the Locations section
Open your campaign in Google Ads. Go to Settings, then Locations. Click the pencil icon to edit your location targets.
Enter zip code with proper formatting
Type the zip code followed by the state or country name. Per Google's Ads Guide, the correct format is `94103, California` or `76622, US`. Do not enter the zip code alone. Google needs geographic context to return the correct match.
Set presence vs. presence or interest
Google Ads offers two targeting types. "Presence" targets people physically located in that zip code. "Presence or interest" also reaches people who have shown interest in that area. For local service businesses, "presence" gives tighter, more relevant reach.
Save and verify your targeting
Click Save. Then open the geographic report under the Locations tab to confirm ads are serving in the intended area. Wait a few days for meaningful data before drawing conclusions.
Zip Code Targeting Best Practices
Format requirements and common mistakes
Always pair the zip code with the state or full country name. Entering `94103` alone returns no match. Entering `94103, California` works correctly. Check the format before saving, not after.
When to use zip code vs. radius targeting
Zip codes follow defined political or postal boundaries. Radius targeting draws a circle from a central address. Use zip codes when matching a service territory or delivery zone. Use radius when your business serves a fixed distance from one location.
Batch targeting rules (1000 limit per batch)
Google Ads lets you add up to 1,000 location targets at a time. If you need more, add them in separate batches. There is no documented cap on total locations per campaign.
Monitoring performance by postal code
Per Google Ads documentation, geographic performance data is viewable at the postal code level. Use it to identify which zip codes drive conversions, which drain budget, and which to exclude entirely.
Limitations and When Zip Code Targeting May Not Work
Minimum area and user count privacy thresholds
Google Ads enforces privacy thresholds. Radius targets under 1 km are not permitted. Zip codes with very low user counts may not qualify as targetable locations at all.
Why small targets show intermittently
Per Google's Ads Help Center, small location targets may cause ads to show intermittently or not at all if they do not meet Google's minimum targeting criteria. If a zip code is too small, expand to a neighboring area or combine multiple postal codes into one campaign.
Location accuracy: signals and their limitations
Location targeting is not guaranteed to be 100% accurate. Ads can occasionally serve to users just outside the target boundary. Monitor geographic reports regularly and exclude locations that consistently underperform.
Make Zip Code Targeting Work Harder for Your Business
Pairing geographic targeting with local messaging
Tight targeting without local messaging leaves conversions on the table. An ad that reflects where your customers live and what they care about outperforms a generic one aimed at the same zip code.

Frequently Asked Questions
Do I need to include the state or country when entering a zip code in Google Ads?
Yes. Google requires geographic context alongside the postal code. The correct format is '94103, California' or '76622, US'. Entering the zip code alone returns no match in the location search.
What happens if my target zip code is too small?
Small location targets may cause ads to show intermittently or not at all. This happens when the zip code does not meet Google's minimum targeting criteria for user count or geographic area. Expand to a neighboring area or combine multiple postal codes to fix this.
What is the difference between 'Presence' and 'Presence or interest' in Google Ads location targeting?
'Presence' targets people who are physically located in your target zip code. 'Presence or interest' also includes people who have shown interest in that area through their search behavior. Local businesses typically get tighter reach with 'Presence'.
How many zip codes can I add at once in Google Ads?
Google Ads allows up to 1,000 location targets per batch. If you need to target more zip codes, add them in separate batches.
