Get the gateway id(s) from the meta data, like from the MQTT JSON message or by expanding an item in the device’s Data page in TTN Console.

Next:

- Simply find the matching id in the popups of nearby gateways on [your local community](https://www.thethingsnetwork.org/community/)’s map. This also gives you a link to the owner, if the gateway’s privacy settings allow for that:

- Or, use that id in a TTN Mapper URL. If it starts with `eui-` such as `eui-0000024b080606d8` then remove that prefix and uppercase the rest:

- Or, get the specific gateway from, e.g.:

- Similarly, one could use the id in a NOC URL, yielding slightly different details (beware, this is an HTTP URL; right-clicking and some “open in new incognito window” might help if your browser tries HTTPS instead):

- Likewise, use [the Account Server API](https://www.thethingsnetwork.org/docs/network/account/api.html#get-gatewaysgw_id), showing different details but still including the owner:

- Likewise, use [the `ttnctl` command line interface](https://www.thethingsnetwork.org/docs/network/cli/):

- To get all gateways around some location:

- To get all gateways in some country:

- To get all gateways of a specific user:

- You can paste the coordinates into Google Maps:

Beware:

- ⚠ The `http://noc.thethingsnetwork.org:8085` endpoint [is known to be unreliable](https://status.thethings.network/incidents/3zddstxw97k9).

- ⚠ The endpoints starting with [https://www.thethingsnetwork.org/gateway-data/](https://www.thethingsnetwork.org/gateway-data/) might not be officially supported APIs. As for validity/caching of that specific endpoint, @htdvisser wrote on Slack:

- ⚠ The coordinates in an uplink’s metadata may be different from what is reported using the methods above. Presumably that is caused by a gateway including GPS/GNSS coordinates, or _fake_ GPS/GNSS coordinates (which it [should not do](https://www.thethingsnetwork.org/forum/t/gateway-gps-configuration-in-local-conf-json/6176/4)) in its messages. It seems `ttnctl gateways status` uses the coordinates from the last uplink’s metadata, while `ttnctl gateways info` reports whatever is configured in TTN Console.
