Determining user location using the user IP address

  • Advertisers
  • Agencies
  • Ad Networks

Targeting new or existing users may rely on knowing user location. Marketers segment their users based on their geographic location, which affects the creatives to be used, ad cost, and the overall engagement and quality of the users.

Determining user location

Each time a user performs an action that reaches AppsFlyer, that is an install or in-app event, AppsFlyer extracts the IP address of the user's device at the time of the action.

Appsflyer converts the IP address into location information using a third-party global provider, Digital Element. AppsFlyer periodically fetches the global IP addresses list from Digital Element, which is used to convert IP addresses of users into accurate Geo locations.

Example: Raw location data

Every entry in AppsFlyer raw data contains the following location-related fields, based on the IP address:

  • Region
  • Country Code
  • State
  • City
  • Postal Code
  • DMA (where applicable)

Where is the location information available in AppsFlyer?

AppsFlyer's various pages and aggregated reports utilize the location data to segment geographically distributed cohorts of users.

Examples include:

Reasons for location discrepancy

In some cases there may be differences in the derived location of users between AppsFlyer and other platforms, even if the other platform also uses Digital Element to resolve IP addresses.

The following is a list of possible reasons for such differences:

  • Periodic updates - to enable fast attribution, AppsFlyer resolves the IP addresses into location data internally. This means that AppsFlyer fetches the global map from Digital Element periodically and not in real time. If AppsFlyer and the other platform have fetched Digital Element data on different dates, changes may be present.
  • ISP Changes - Digital Element's databases are rapidly changing as ISPs are frequently changing their IP mappings.
  • Different Plans - Digital Element offers different package plans based on the required level of accuracy. Other platforms may be using other Digital Element package plans than AppsFlyer's, which may give different IP address resolving.
