How do I set up a US proxy?

How do I build the proxy username?

Start from your base username and append segments in the order of USERNAME-country-{cc}-state-{state}-city-{city}-zip-{zip}-asn-{asn}-session-{id}-ttl-{minutes}, leaving out those you do not need. Rules the gateway applies:

• Values are lower case, with _ instead of spaces: city-san_antonio.
• asn- takes the number only: asn-7922 for Comcast's AS7922.
• session- takes 1 to 32 letters or digits that you choose.
• ttl- is in minutes. Sticky sessions last up to 30 minutes, set per session with the ttl parameter; the IP can change earlier.

The ZIP segment has its own guide: what is ZIP code proxy targeting.

How do I test a US proxy with curl?

Send one curl request through the gateway: if the reply shows a US IP, the setup works. The first command uses the HTTP port; the second uses SOCKS5.

# HTTP proxy, Texas, rotating
curl -x http://gw.lodestate.com:7777 \
  -U "USERNAME-country-us-state-tx:PASSWORD" \
  "https://api.ipify.org?format=json"

# SOCKS5 proxy, same exit (socks5h resolves DNS through the proxy)
curl -x socks5h://gw.lodestate.com:7778 \
  -U "USERNAME-country-us-state-tx:PASSWORD" \
  "https://api.ipify.org?format=json"

# where does a geolocation database place the IP?
curl -x http://gw.lodestate.com:7777 \
  -U "USERNAME-country-us-state-tx:PASSWORD" \
  "https://ipinfo.io/json"

How do I use a US proxy in Python requests?

Pass the proxy URL to requests through the proxies argument; the same URL serves HTTP and HTTPS targets. Each requests.get() call opens a new connection, so a rotating username gets a new home IP each time. A sticky username keeps one IP.

import requests

GATEWAY = "gw.lodestate.com:7777"
PASSWORD = "PASSWORD"
ECHO = "https://api.ipify.org?format=json"

def proxies_for(username):
    url = f"http://{username}:{PASSWORD}@{GATEWAY}"
    return {"http": url, "https": url}

# rotating: a new connection per call, usually a new Texas home IP
rotating = proxies_for("USERNAME-country-us-state-tx")
for _ in range(3):
    print(requests.get(ECHO, proxies=rotating, timeout=30).json()["ip"])

# sticky: the session id keeps one New York City IP for up to 10 minutes
sticky = proxies_for("USERNAME-country-us-state-ny-city-new_york-session-nyc01-ttl-10")
for _ in range(3):
    print(requests.get(ECHO, proxies=sticky, timeout=30).json()["ip"])

How do I set a US proxy in a browser or a scraping tool?

Enter the same four values, host, port, username and password, in the tool's proxy settings.

• Firefox: Settings, Network Settings, Manual proxy configuration. Put gw.lodestate.com and port 7777 in HTTP Proxy and tick "Also use this proxy for HTTPS". Firefox asks for the username and password on the first page.
• Firefox and SOCKS5: Firefox has no SOCKS username field, so use the HTTP port or the IP allowlist.
• Chrome and Edge: they read the operating system's proxy settings and prompt for the login.
• Scrapy: set request.meta["proxy"] to http://USERNAME-country-us:[email protected]:7777.

Why does my US proxy return a 407 error or time out?

A 407 means the gateway refused the login; a timeout or an early error usually means a wrong port or an unreachable target. Check these in order:

1. 407 Proxy Authentication Required: a password typo, or a username segment the gateway rejects (capital letters, a space, a misspelled city id).
2. Error right after connecting: SOCKS5 traffic sent to port 7777, or HTTP sent to port 7778.
3. No IP for the place: no home is online in that ZIP or city right now. Widen to the city, then the state.
4. Allowlist login stopped working: your own IP changed. Add the new one, or log in with the password.
5. One site never loads: Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587 are blocked.

How much should a first test cost?

$1.50 for 1 GB covers a full test of every targeting level, and it costs less per GB than the paid trials we found. According to Lodestate's check of 29 October 2026, NodeMaven's $3.50 trial gave 750 MB, or $4.67/GB. ProxyEmpire's $1.97 trial gave 150 MB, or $13.13/GB.

No free trial — test with the 1 GB plan, paid from the minimum top-up; the part added only to reach the minimum is refundable on request within 30 days, in USDT or USDC, if unspent. From 5 GB the rate drops to $0.75/GB, half the 1 GB rate. Prepaid residential and rotating-mobile traffic never expires: unused GB stay on your account until you use them. All tiers: how much do US residential proxies cost per GB.

How do I set up a dedicated mobile port instead?

A dedicated 4G/5G port works the same way, with its own host, port and login shown in your dashboard. The username needs no targeting segments: the carrier is fixed when you buy the port. The IP changes when you rotate it, by link, API call or timer, as shown in how do I rotate a mobile proxy IP.
