Postal Code Lookup Scraper

Postal Code Lookup Scraper

Resolve any postal code to its place, region, and coordinates in one batch. Feed country and postcode pairs, get back every matching place with its latitude, longitude, and administrative hierarchy. No API key, no rate limits, export to CSV, JSON, Excel, or XML.

Zippopotam is a free postal code lookup service covering over 60 countries, but its API only resolves one postcode at a time and returns nested JSON that is painful to flatten. This Actor resolves thousands of postal codes in a single run, strips the nesting, and returns one flat row per place. It handles multi-place postcodes, short-form codes for the UK, Canada, Netherlands, Brazil, Malta, Crown Dependencies, and Poland, and works without any API key or registration.

What you can do with Zippopotam data

🚚 Validate delivery postcodes.

A logistics company runs a nightly batch of 50,000 customer postcodes through the Actor to confirm each one resolves to a real place and to append coordinates for route optimization.

🧹 Clean CRM address data.

A data steward feeds a list of postal codes from a CRM export and uses the returned place names and regions to standardize inconsistent address fields.

🗺️ Build regional sales maps.

A market analyst resolves a list of postcodes from sales transactions and maps the resulting latitude and longitude pairs to visualize revenue by territory.

🔎 Pre-warm address autocomplete.

An e-commerce developer populates a search cache with valid postcode-to-place mappings so the storefront autocomplete responds instantly without hitting an external API per keystroke.

📍 Create GIS point layers.

A GIS specialist converts a spreadsheet of postal codes into a point feature class by running the Actor and importing the flat CSV with coordinates into ArcGIS or QGIS.

Configure the run

Drive the Actor with an array of country and postcode pairs, and control whether multi-place postcodes are exploded into separate rows or packed into one. The Input tab lists every parameter.

A first run with the defaults:

 },
 {
 "country": "de",
 "postcode": "10115"
 }
 ],
 "maxItems": 10
}

Troubleshooting

Why am I getting no results?

Check that your country codes are lowercase ISO-2 and your postcodes are valid for that country. For UK, Canada, Netherlands, Brazil, Malta, Crown Dependencies, and Poland, use the short form without spaces or inward suffix.

Why does my run stop after 10 items?

Free users are limited to 10 postal codes for preview. Upgrade to a paid Apify plan to increase maxItems up to 1,000,000.

Why do I get multiple rows for one postcode?

Some postcodes match multiple places. By default, explodePlaces is ON, so each place becomes its own row. Set explodePlaces to false to pack all places into one row.

Why is my UK postcode with a space rejected?

The Actor automatically strips spaces and inward suffixes for UK postcodes. Use the outward form like SW1A instead of SW1A 1AA.

Why does the run take a long time for many postcodes?

The Actor processes lookups sequentially to respect the public service. For very large batches, consider splitting into multiple runs or increasing the timeout.

Why are some fields empty in the output?

Zippopotam may not return all fields for every place. Empty fields are normal when the source data lacks that information.

What happens if a postcode matches multiple places?	By default, explodePlaces is ON, so each place becomes its own output row. If you turn it OFF, all places for that postcode are packed into a single row.

Can I export the results?	Yes. The Actor outputs a flat dataset that can be exported to CSV, JSON, Excel, or XML from the Apify platform.
Is there a rate limit?	The Actor respects Zippopotam's public service availability. For large batches, the Actor processes requests sequentially to avoid overwhelming the endpoint.
