Plot a list of addresses on a map
How do you plot a list of addresses on a map?
The interface reads up to 50 nonblank lines, but anonymous geocoding allows 30 uncached lookups per minute per requester. For a reliable all-new batch, use 30 or fewer addresses and download the results before refreshing.
How the batch is read
Paste one address per line. Blank lines are removed and only the first 50 nonblank lines are considered by the interface.
- Addresses are processed sequentially with a short delay
- Successful results become labeled map markers
- A normal no-match result remains as a row without coordinates
- The latest committed results are held only in browser component state
The 50-line interface and 30-miss limit differ
Anonymous geocoding permits 30 cache misses per minute per requester. A batch of 31 to 50 entirely new addresses can therefore hit the limit even though the interface accepts 50 lines.
- Use 30 or fewer addresses for a reliable all-cold anonymous batch
- Previously cached queries do not count as cold misses
- A hard request failure, including rate limiting, can abort the run before the new rows are committed
Prepare addresses for useful matches
Provide enough location context for the geocoder to distinguish similarly named streets and places.
- Use street, city, region, postcode, and country where available
- Keep one logical address on each line
- Remove private notes or identifiers that do not help resolve the location
- Review every marker rather than treating a success status as proof of the intended match
CSV and GeoJSON downloads are different
The CSV contains every committed row with blank longitude and latitude for unresolved addresses. The GeoJSON contains only successful points.
- CSV columns are address, lng, and lat
- GeoJSON point properties preserve the address label
- Neither download is saved automatically; export before refreshing
Data handling and the full-map next step
Address values are sent to the MapsMaker geocoding endpoint and query results are cached for 30 days. Use the editor when you need saved records, filters, media, sharing, or an eligible website embed.
- Do not submit sensitive addresses if the geocoding retention is unsuitable
- Use the CSV sample helper when the input already has headers and more fields
- Use the full editor for plan-governed imports and an ongoing publishing workflow
