Test the proxy with curl. The check prints the exit IP, not a country; if a lookup of that address names another country, check why location lookups can disagree. For Python configuration and error handling, follow the Requests setup guide.

• A sticky session keeps the same device. The carrier may still change the IP of that device. We do not sell fixed IP addresses on this product, and the pool in the United States is shared.
• A session lifetime is set once per session name with a ttl token, from 60 to 2592000 seconds, and cannot be changed afterwards.
• Mobile traffic runs on carrier modems operated by our network partner; residential traffic runs on opt-in peer devices in the partner network.

Compare rotating and sticky sessions, including why a sticky session can change IP.

• Price and marketplace monitoring

  Read the public price a shopper in the United States is shown, quoted in USD, together with the delivery and tax lines that come with it.

• Ad verification and brand safety

  Check how a creative and its landing page render for an audience in the United States served in English, on an ordinary home connection.

• Country-level price collection across a large catalogue

  Read the public US price list at the scale a catalogue needs, on home connections, with the postcode and the schedule held constant so the rows stay comparable from week to week.

• QA and geo-testing

  Load your own site from an exit in the United States with Accept-Language: en-US, and check the USD price, the English copy, hreflang, the payment methods offered and any redirect between store fronts.

• AI agents and data pipelines

  Give an agent or a scheduled job an egress in the United States that it selects itself by writing peer-us into the username.

How do I get a United States IP address?

Buy GB, then put peer-us in the proxy username and connect to our gateway over HTTP or SOCKS5: USERNAME-peer-us-rot-auto10. The pool is opt-in peer devices in the United States and it is shared between customers; the "IPs online now" row at the top of this page is the live count from our stock endpoint, and it is left out when the endpoint does not answer. If no device in the United States is online, the gateway answers 502 with E_NO_STOCK_COUNTRY instead of quietly sending you to another country.

What does United States traffic cost?

The same as every other country: one price list for both pools, EUR 4.50 per GB for a small order falling to EUR 2.50 per GB at the largest step, with the live table on this page. GB never expire. What you buy stays on your balance until you use it; a new purchase adds to the same balance. You can start with 0.5 GB for EUR 2.90, or buy from 1 GB. Payments are accepted in cryptocurrency.

Can I hold the same United States exit for a whole session?

Yes, with a session name: USERNAME-peer-us-sid-run1-rot-sticky. The same sid returns to the same device while it is online. A sticky session keeps the same device. The carrier may still change the IP of that device. Set the lifetime once per session with a ttl token, between 60 and 2592000 seconds; it cannot be changed afterwards. Write your job so a dropped device is retried rather than treated as a failure.

Should I use mobile or residential for United States?

The United States is one of the countries where we run both pools, so the choice is one token in the username: peer-us or mbl-us. Choose mobile when the job specifically requires a carrier-network exit. Keep the browser, viewport and account settings consistent when comparing the two pools; the network address alone does not select a desktop or phone layout. Both pools use the same GB balance. One balance covers both, so the honest answer is to run the same job twice and compare what comes back.
