Mobile supports two targeting modifiers: country- and asn-. State and city targeting are not available on mobile.

Format

Country targeting

Use any supported ISO 3166-1 alpha-2 country code. Lowercase.

Carrier (ASN) targeting

asn-<number> pins your IP to a specific mobile carrier by its Autonomous System Number. Useful for testing content delivery, ad targeting, or app behaviour specific to a carrier’s network.

Common US mobile carrier ASNs

Find the ASN for any mobile IP using whois, bgp.he.net, or ipinfo.io.
Carrier ASN availability depends on the active pool. If an ASN has no IPs available, you’ll receive a 454 invalid asn response — drop the asn- modifier to use any carrier in that country.

Sessions

Mobile supports sticky sessions with the same session- + ttl- (minutes) format as residential:
See Residential → Sessions for the full mechanics — they’re identical on mobile.
