IP geolocation has approximate accuracies of 95-99% on country level, 80% on state/region level and 70% on major city level.

IP geolocation should only be used to detect countries, states/regions and major cities. Any finer location detection within a city itself such as suburb or zip code detection is not recommended.

It is important that you understand the benefits and limitations of IP geolocation before utilizing it to segment your website visitors.
