Build postal code lists for geo-targeted ads in under a minute
Every major ad platform can target by postal code. None of them will tell you which postal codes are within 20 miles of your store. That's the step RingFence does in seconds.
Why postal code targeting beats a radius pin
Most ad platforms offer a radius pin: drop a point, pick a distance. It's quick, but it's a black box. You can't see which neighborhoods are in, you can't carve out the area across the river you don't serve, and you can't reuse it on the next platform. A postal code list fixes all three:
- Auditable. Every code in the campaign is on a list someone can review.
- Editable. Drop the codes you don't serve; add the one just outside the circle that you do.
- Portable. The same list works for search ads, social ads, direct mail, and your CRM.
The workflow
- Search. Enter your store's postal code or town and the radius. RingFence returns every postal code inside the circle, nearest first.
- Refine. Filter the table by state, town, or distance. Delete rows you don't serve. The postal code list updates as you go.
- Copy or download. Copy the codes one per line or comma-separated, whichever your platform's bulk location tool expects, or download a CSV.
- Upload. Paste into the platform's bulk location targeting. Done.
Running campaigns in more than one country
This is where most ZIP tools give up. RingFence uses the same workflow for a 20 km radius around Munich, a 15-mile radius around Manchester, or a 30-mile radius around Toronto. One tool, one export format, every market. Switch the unit to kilometers and keep going.
Automate the recurring ones
If you launch a campaign for every new location, call the RingFence API with format=zip_list and get back one postal code per line, ready to feed into whatever builds your campaigns.

Every impression outside your service area is wasted budget. A precise postal code list, built in seconds and reused everywhere, is the cheapest optimization in local advertising.
Frequently asked questions
Why target ads by postal code instead of a radius pin?
A postal code list is explicit and auditable: you can see exactly which areas are in, remove ones you don't serve, add ones you do, and reuse the same list across platforms and channels.
How do I get a list of ZIP codes within a radius for ads?
Search the center and radius in RingFence, filter or edit the results, then copy the postal codes with your choice of separator or download them as CSV for bulk upload.
