Claude Proxy: Dedicated Native IP, 15 PTC for 30 Days
A dedicated IP for Claude: one native IP for Claude.ai and Claude Code — with Anthropic's region rules spelled out.

Why Claude needs a proxy setup that fits its rules
Anthropic's Supported Regions Policy goes beyond your IP address. Claude.ai, the API and Claude Code are offered only in listed countries — mainland China, Hong Kong, Macau and Russia are not among them — and the policy covers use while you are physically located in an unsupported region. Since September 2025 it also covers companies more than 50% owned by entities headquartered in unsupported regions, wherever they operate.
Sign-up adds a second check: every new account must verify a phone number from a supported location, and VoIP, Google Voice and app-generated numbers are refused. A proxy changes neither rule.

Where a fixed IP does help is the network itself. Claude Code reads standard proxy variables but doesn't support SOCKS, so it needs an HTTP proxy. Claude Enterprise can restrict access to allowlisted IP ranges such as office and VPN exits — a static IP gives remote team members one address the admin can add. And a team in a supported country keeps every member on one stable exit instead of a shared VPN.

Set up a Claude proxy in 5 minutes
Open the Claude ISP page and order
Open the Claude ISP page (the button at the top; the right plan tab is selected). Leave City on Auto, which picks the best-stocked city, or choose one from the list. Protocol is HTTP by default and SOCKS5 is optional. Keep HTTP if the IP is for Claude Code. Auto-renew is ticked by default, and the term is 30 days. The button shows the price in PTC (15 PTC, with the first-subscription discount if you are eligible). Click Pay.
Expected result The result shows the IP, its range, ASN, operator, city and expiry date. The IP is also in My assets, where you find host, port, username and password.
Browser and Claude.ai
Install the Proxy302 browser extension (Downloads and setup at the bottom of /guides) and press Sign in. In My assets, click Use extension on this IP's row (the extension takes HTTP IPs only), then press Connect in the extension. Open ipinfo.io to confirm the country, then open claude.ai.
Claude Code in the terminal
Set HTTPS_PROXY to the HTTP IP as shown below, start claude and run /status: the Proxy row shows the URL in use. Claude Code stops at launch if the URL can't be parsed, for example without the http:// prefix.
For a Claude Enterprise allowlist
Send the IP to your admin. Anthropic adds allowlisted ranges on request, so do this before you route the team through the new address.
Before continuing If your network can't reach the proxy directly, open Proxy302 Fast Connect (Tools & checks page) and click 「一键加速」 (One-click boost) first.
Run Claude Code through the proxy
Scroll horizontally with the arrow keys to read all content.
# Claude Code reads the standard proxy variables. It doesn't support SOCKS,
# so use an IP bought with Protocol = HTTP.
export HTTPS_PROXY="http://USERNAME:PASSWORD@HOST:PORT"
claude
# Inside Claude Code, run /status and check the Proxy row.Claude Code uses the first of https_proxy, HTTPS_PROXY, http_proxy, HTTP_PROXY that is set, and accepts basic-auth credentials in the URL. To make it permanent, put the same variable in the env block of ~/.claude/settings.json.
Quick fixes
claude.ai says Claude isn't available in your region
Check Open ipinfo.io in the same browser. Is the exit in a country on Anthropic's list?
Fix Turn the extension proxy on for this browser or switch to an IP in a supported country. Remember the policy also depends on where you physically are.
Your team is locked out after turning on IP allowlisting
Check Is the static IP on the allowlist your admin sent to Anthropic?
Fix Add the address (or its /32 range) to the allowlist and keep everyone on that exit.
Sign-up stops at phone verification
Check Is the number a mobile number from a supported location, not VoIP or an app number?
Fix A proxy can't help here: Anthropic only accepts numbers from supported locations.
Claude proxy FAQ
Can I use Claude from an unsupported country with a proxy?
Anthropic's policy is about where you are physically located, not only the IP you connect from, and it also covers companies majority-owned from unsupported regions. A proxy changes your network exit; it doesn't make that use permitted.
Does Claude Code work with a SOCKS5 proxy?
No. Claude Code documents HTTP/HTTPS proxy variables only and says SOCKS proxies aren't supported, so choose Protocol HTTP when you order.
Do I still need a phone number?
Yes. Every new account verifies a phone number from a supported location; VoIP and app-generated numbers aren't accepted.
Can our Enterprise allowlist include a Proxy302 IP?
Claude Enterprise allowlists take CIDR ranges such as office and VPN exits. A static IP stays the same for the term, so you can submit it as a single address.
Which should I buy: the Claude ISP, a regular static IP or rotating?
The Claude ISP: one dedicated native IP per person that does not rotate during the term. A regular static IP is the budget option. A rotating IP changes between requests, so a signed-in account would show up from many addresses; use rotating residential only for work that doesn't sign in.
How much is the Claude ISP, and is there a discount?
15 PTC for 30 days (1 PTC = US$1). Per account, the first 30-day IP in each plan is half price. Renewals and the second IP onward are full price.
