How to Send IP Address with Mixpanel SDK While Retaining Country and City Data?

·Apr 24, 2026 03:56 AM·

Hi everyone! I’m aware that mixpanel is now using maxmind service for geolocation detection. Currently we didn’t send the IP address by default in our current implementation. Does anyone know how to send the IP address to all events from Mixpanel SDK but still keeping the country and city?

Hi Novita, I'm Leo from Mixpanel Support team. Happy to assist! Are you using a server or client-side SDKs? Asking because client-side SDKs do all these automatically so you do not have to send the IP. We use the IP of the incoming request, set the geolocation then discard the IP for privacy reasons. Looking forward to hearing from you. Kind regards, Leonardo Fratini Support @ Mixpanel Barcelona | Spain

I need this for both BE and FE tracker, but I believe all will be handled from client side. I know that the current geolocation is mapped automatically, but we still need the IP info for security reasons and fraud checking 🙏

Hi Novita, If you need the IP Address you will need to start sending and ingest IP Addresses as a property from your implementation. Mixpanel doesn't keep IP Addresses but you can still send them as regular properties in your events. Kind regards, Leonardo Fratini Support @ Mixpanel Barcelona | Spain

Hi Leonardo, The problem is our FE don’t have the IP address data. Previously we get the data from Amplitude automatically along with the location info (city, region, etc)

Hi Novita, In Mixpanel:
We use the request IP to set $city, $region, mp_country_code, then .
If you also need to store the IP, you must send it as a custom property (e.g. "client_ip"), not ip / $ip.
Since your FE can’t see the IP, the usual pattern is:
Backend reads the client IP from the incoming request.
Backend sends the event to Mixpanel with:
"ip": client IP (for geolocation parsing, will be dropped)
"client_ip": client IP (or similar name, which will be stored for fraud/security checks)
That way you preserve Mixpanel geolocation and still keep the IP for your own analysis. Kind regards, Leonardo Fratini Support @ Mixpanel Barcelona | Spain
