Best Proxies for Ad Verification in the US: State, DMA and Carrier Checks

Why does ad verification need US IPs at state and DMA level?

Ad verification needs IPs inside the targeted area, because ad platforms serve ads by location. A check from outside that area sees a different result. A campaign bought for the Houston DMA should appear in Houston, not in Dallas. Checking from the right location confirms three things:

• Delivery: the ad shows where it was bought, and not outside that area.
• Creative: the right version, language and offer appear in each market.
• Landing page: redirects end on the correct, safe page for that location.

Geo-testing your own site works the same way: load it from several states and compare what each visitor sees.

What is a DMA, and which DMAs do the largest US cities belong to?

A DMA (Designated Market Area) is a US media market: a group of counties around a core city that advertisers buy as one unit. DMAs can cross state lines; the "Washington, DC (Hagerstown, MD)" DMA reaches into Maryland. AmericaProxies has no DMA parameter, so target the DMA's main city or several ZIP codes inside it. The table covers the 10 largest DMAs, with names and ranks from the US cities hub.

How do I check in-app and mobile ads by carrier?

Use a dedicated mobile port on the carrier you want to check, because in-app ad systems can read the carrier network behind an IP. AmericaProxies rents ports on T-Mobile, AT&T and Verizon. Their wireless networks are AS21928, AS20057 and AS22394/AS6167, per RIPEstat. MVNO users ride the same networks: Cricket on AT&T, Visible on Verizon and Metro by T-Mobile on T-Mobile.

Run the app on a test device or emulator through the port, then rotate the IP between checks. AmericaProxies does not list port stock by city, so carrier checks are national. City-level checks use residential IPs. Compare carriers on the US mobile proxies page.

Which targeting recipe fits each ad check?

Match the proxy to the way the campaign was bought: state, DMA, ZIP code, ISP or carrier. Add segments to the gateway username USERNAME-country-{cc}-state-{state}-city-{city}-zip-{zip}-asn-{asn}-session-{id}-ttl-{minutes} and drop the ones you do not need. Use a sticky session whenever one check spans several requests.

How do I geo-test a website or app from different states?

Load your site or app through residential IPs from several states and compare what each visitor sees. Typical geo-testing checks with AmericaProxies:

• Prices, taxes and shipping messages that change by state or ZIP code.
• State-specific notices, such as privacy or age banners.
• Store locators and local stock for New York, Texas or California visitors.
• Time-based content across the Eastern, Central, Mountain and Pacific time zones.

Use one sticky session per state, so each test run keeps a single IP. The US state pages list every state code.

How much do ad verification proxies cost?

Ad verification with AmericaProxies costs $1.50 for 1 GB of residential traffic and falls to $0.52/GB at volume, as of October 2026. A plan above $25 is paid at its exact price; a smaller plan is paid from a $25 minimum top-up, and the part added only to reach the minimum is refundable on request within 30 days, in USDT or USDC, if unspent. Ad checks load full pages, so budget by page weight. For example, a check that loads 2 MB allows about 500 checks per GB. A dedicated US mobile port costs $45 for 30 days with unlimited data under fair use, which suits frequent in-app checks. Every tier is on the pricing page.
