Authorised services come from the lists importers publish on their websites, for brands that sell at least one electric model in Serbia or whose models are already common on the road (Nissan Leaf, Renault Zoe, BMW i3). Independent services are on the map only when their own website or page says they work on electric cars. Each service has a source and the date it was checked.

A body shop is on the map when an authorised service has one or when it says on its own website that it repairs electric cars. A tow service is on the map when its website mentions transporting vehicles on a flatbed; whether it also carries electric cars is stated when it says so.

A point on the map comes from the importer's or the service's website; when it gives none, it is placed by address with OpenStreetMap. Nothing is taken from Google Maps or other maps. Services have no ratings and are not ranked by quality; the list is sorted by distance or by name, the same for everyone.

When a website does not say something, the map says “Not mentioned”. A service is missing or a detail is wrong? Send a correction. A service can send its details itself through the page for companies; only public, verifiable facts are published.
