## Why does ad verification need IPs in each state and DMA?

Ad verification needs IPs inside each targeted area because ad platforms serve campaigns by state, DMA, city or ZIP radius. Only a viewer inside the area gets the ad, the offer and the landing page meant for it.

**An ad verification proxy loads a page from inside the targeted state, DMA or ZIP code, so you record what a local viewer gets.**

A DMA (Designated Market Area) is a Nielsen TV market, and many DMAs cross state lines. The El Paso DMA includes Las Cruces, New Mexico. The Washington, DC DMA includes Hagerstown, Maryland. A campaign bought for one DMA therefore needs checks on both sides of the line.

## Which US markets can I check ads from?

You can check ads from any of the 50 states and Washington, D.C., and from any city or ZIP code where IPs are available. **FiftyStateProxy's 30 city pages sit in 28 distinct DMAs, including all ten of the largest US TV markets.** Dallas and Fort Worth share one DMA, and so do San Francisco and San Jose.

### The ten largest DMAs, with a sample ZIP code each

| DMA | City page | Sample ZIP code | Username part |
| --- | --- | --- | --- |
| New York | New York City, NY | 11372 (Jackson Heights) | `-state-ny-city-new_york-zip-11372` |
| Los Angeles | Los Angeles, CA | 90049 (Brentwood) | `-state-ca-city-los_angeles-zip-90049` |
| Chicago | Chicago, IL | 60608 (Pilsen/Bridgeport) | `-state-il-city-chicago-zip-60608` |
| Dallas-Ft. Worth | Dallas and Fort Worth, TX | 76104 (Near Southside) | `-state-tx-city-fort_worth-zip-76104` |
| Philadelphia | Philadelphia, PA | 19125 (Fishtown) | `-state-pa-city-philadelphia-zip-19125` |
| Houston | Houston, TX | 77030 (Texas Medical Center) | `-state-tx-city-houston-zip-77030` |
| Atlanta | Atlanta, GA | 30318 (West Midtown) | `-state-ga-city-atlanta-zip-30318` |
| Washington, DC (Hagerstown, MD) | Washington, DC | 20009 (Dupont Circle/Adams Morgan) | `-state-dc-city-washington-zip-20009` |
| San Francisco-Oakland-San Jose | San Francisco and San Jose, CA | 94117 (Haight-Ashbury) | `-state-ca-city-san_francisco-zip-94117` |
| Boston (Manchester) | Boston, MA | 02127 (South Boston) | `-state-ma-city-boston-zip-02127` |

DMA names and ZIP codes come from the FiftyStateProxy city dataset (Nielsen DMAs, as of October 2026). More ZIP codes sit on each city's own page.

## Residential or mobile: which proxy checks which placement?

Use residential IPs for anything targeted by place, and a dedicated carrier port for anything targeted by mobile network. A port is picked by country and carrier from the stock shown at checkout, so state-level proof belongs on residential IPs.

| What you verify | Proxy to use | Why |
| --- | --- | --- |
| Display or search ads aimed at a state or DMA | Residential, state or city targeting | The IP sits inside the targeted market |
| Geo-fenced ads aimed at a ZIP radius | Residential, ZIP targeting | The narrowest place a username can set |
| Campaigns aimed at one home ISP | Residential, ASN targeting, such as `-asn-7922` (Comcast) | The IP belongs to that ISP's network |
| Mobile web and in-app ads aimed at a carrier | Dedicated T-Mobile, AT&T or Verizon port | The exit is a modem on that carrier's SIM |
| Nationwide mobile reach | Rotating mobile per GB, country level | A fresh carrier IP on each connection |

## How do I run a state-by-state ad check?

Connect the gateway once, using [how do I configure a US proxy in my browser or script](https://fiftystateproxy.com/how-to-set-up-a-us-proxy/ "Step-by-step US proxy setup guide"). Then repeat these steps for each campaign.

1. **List the campaign's targets** — Write down every state, DMA and ZIP radius in the media plan, with the creative each one should see.
2. **Map each target to a username** — For example -state-tx-city-el_paso-zip-79912 for El Paso and -state-nm for the New Mexico side of the same DMA.
3. **Keep one sticky session per target** — Reuse one session ID per target, so the ad call, the click-through and the landing page share one IP.
4. **Capture the evidence** — Save a screenshot, the creative ID and the landing URL for each target, with the time and the exit IP.
5. **Repeat on a carrier port** — Run the mobile placements again through a T-Mobile, AT&T or Verizon port.
