Geo-targeting lets you tell the proxy network "give me an IP from the United States" — or, on more precise networks, "give me an IP from California, San Francisco, ZIP 94110". The destination site sees you as a local user from that geography and serves you the local version of its content.
Granularity varies by provider. Country-level targeting is universal (every provider offers it). State and city are common on enterprise providers (Bright Data, Oxylabs, Decodo (formerly Smartproxy)). ZIP-code level is rare and almost exclusively offered by Bright Data. ASN-level (specific ISP within a country) is offered by Bright Data and a few others.
Common use cases: ad verification (does my ad show in Detroit?), local SEO (what does Google show for "pizza near me" in Hyderabad?), price monitoring (is this product cheaper on the German Amazon?), market research (what TikTok content trends in Indonesia?).
