How to Use Claude in 2026: Network & Static IP Guide
Clean IP picks: Static IPs from $1.5 each, Dynamic IPs from $0.5/GB
Claude is an AI assistant developed by Anthropic, widely used for code generation, long-form content, writing, and document analysis.
For cross-border e-commerce, global marketing, and development teams, reliable access to Claude has become part of everyday work.
However, Claude is not available in every country and region.
This guide covers why Claude may be unavailable, what kind of network environment is needed, how a fixed IP can help, and how to configure one. Availability and platform requirements are based on Anthropic's current official guidance.
Why Is Claude Unavailable in Mainland China?
Anthropic's supported-region policy lists the countries and regions where Claude is available and states that individuals located in unsupported regions are not eligible to use the service.
Entities registered or headquartered in unsupported regions, as well as entities majority-owned or controlled by individuals or entities from those regions, are also outside the supported scope.
Mainland China is not on the supported list. Changing your network exit point does not make the service officially supported there, as Anthropic's policy is based on where the user is actually located.
Phone verification is another requirement. According to Anthropic's Help Center:
▸ The number must be from a supported region: When creating an account for the first time, you need a phone number from a supported region to receive a six-digit verification code.
▸ Some number types are not accepted: VoIP numbers, Google Voice, app-generated numbers, landlines, and other numbers that cannot receive SMS messages are not supported.
▸ There is no official bypass: New users must complete phone verification, and Anthropic does not provide an alternative verification method.
So, using an overseas email address alone does not bypass the phone verification requirement.
What Kind of Network Environment Does Claude Require?
If your business is located in a region where Claude is supported, everyday use mainly comes down to three things.
1. A Network Exit in a Supported Region
Your network exit point should be located in a country or region on Anthropic's supported list.
2. A Relatively Stable IP
Frequently switching between countries or network connections can cause your login environment to change repeatedly.
3. A Normal Browser and Account Environment
Common browsers such as Chrome and Edge are sufficient. If you need to manage multiple separate business environments, browser profile isolation can be used when appropriate.
The second factor is usually the hardest to maintain over time. Public VPN services often use shared exit points, their IP addresses may change, and data center IPs can have clearly identifiable hosting or data center network attributes.
Why Consider a Fixed IP for Long-Term Claude Use?
The main difference between network options is how stable the exit IP remains:
In the proxy industry, static residential IPs are also commonly grouped under ISP proxies. The IP remains fixed during the rental period, is assigned to a single customer, and carries ISP network attributes.
Keep in mind that a static residential IP cannot guarantee that an account will never be restricted. Its main benefit is keeping the network exit consistent over time.
How to Configure an IPDEEP Static Residential IP
1. Choose a Country or City
Select a location based on your target market. For long-term use, it is recommended to stick to the same city.
2. Purchase a Static Residential IP
Visit the IPDEEP Static Residential IP product page and choose a location and rental period. Dedicated IPs are not assigned to other users during the rental period.
3. Get Your Connection Details
Get the Host, Port, Username, and Password from the dashboard.
4. Configure It in Your Proxy Tool or Browser
Enter the connection details provided in the dashboard according to the requirements of your proxy tool or browser.
5. Check the IP Information
Use an IP checker to verify the exit country's or city's location, ASN, and network ownership. For a new setup, it is a good idea to check the IP multiple times.
6. Keep the Same Exit IP
For everyday use, try to keep the same connection and avoid frequently switching between nodes.
IPDEEP's Static Residential IPs are dedicated ISP-based IPs that remain fixed during the rental period. They support HTTP, HTTPS, and SOCKS5, with customizable bandwidth up to 50 Mbps, and can be selected by country and city.
Pricing varies by location and rental period. Some promotional nodes start at around $1.70 per IP/month. Check the current purchase page for available locations and pricing.
Frequently Asked Questions
Q1: Can a Static Residential IP Guarantee Successful Claude Registration?
No. A static residential IP addresses network exit stability and IP type.
Whether you can register and use Claude also depends on your physical location, whether your phone number meets the requirements, your account status, and the platform's policies.
Q2: Does Claude Require Phone Verification During Registration?
Yes. New users must complete phone verification using a number from a supported region. VoIP numbers, Google Voice, app-generated numbers, and landlines are not accepted, and there is no official way to bypass verification.
Q3: Can Users in Mainland China Register for and Use Claude?
According to Anthropic's current supported-region policy, mainland China is not on the list. Anthropic states that countries and regions not listed are unsupported. Changing your network exit does not change this policy.
Q4: Which Is Better for Claude: Static or Dynamic Residential IPs?
It depends on how you use them. If you need to log in from the same region over the long term and keep your environment consistent, a static residential IP is more suitable because the exit IP remains fixed during the rental period.
If you need multiple exit points for data collection, price monitoring, or similar tasks, an Dynamic Residential IP is more practical.
Conclusion
Claude is not directly available in mainland China because of its supported-region policy. Changing to a different network tool does not change that policy.
If your business is located in a supported region and requires a stable long-term login environment, using a fixed network exit can be a practical option.
If you need a fixed overseas network exit, visit the IPDEEP Static Residential IP product page to view available locations, bandwidth options, and pricing.
