Country codes for proxies

Why country codes matter

When you choose the exit country in a proxy username or in an API call, you use a two-letter ISO country code. A wrong code is rejected or, in some tools, silently ignored, so it is worth knowing the codes that people mix up. The United Kingdom is gb and not uk, Greece is gr, Switzerland is ch, South Korea is kr, and Vietnam is vn.

The table below lists every country with its codes, its currency and its calling code, and shows which ones ProxyOnly has in stock right now. Stock changes, so use the country page or the order page for the live position.

Using the codes

Codes go in lowercase in the username, and in either case in the API.

Which proxy type fits any country

Pick the proxy type from the job rather than the price. Here is how the types we sell compare, so you can match one to your work in any country:

Datacenter IPv4. The default choice for most jobs. These are dedicated IPv4 addresses hosted in a datacenter, fast and inexpensive, and the best fit for high-volume reading of public pages, monitoring and automation. Some websites treat datacenter ranges more cautiously than consumer connections, so test your target before you commit to a long rental.

ISP proxies. Static addresses that are registered to an internet service provider rather than a hosting company. They keep the speed of datacenter hardware and look more like an ordinary home or office connection, which helps with destinations that are strict about hosting ranges.

Shared IPv4. A shared address is used by more than one customer and costs less. It suits light tasks, quick checks and testing where a clean, exclusive address is not essential.

IPv6. IPv6 addresses are very cheap and plentiful, and they work well with destinations that serve IPv6 traffic, such as many large search, video and social platforms. Many smaller sites are still IPv4 only, so check that your target supports IPv6 before you buy.

Mobile proxies. Addresses from mobile carrier networks. Many phones share the same carrier address, so websites tend to be tolerant of this traffic, which makes mobile proxies the right choice for testing mobile ads, apps and landing pages. They cost more than datacenter addresses.

Residential proxies. Addresses from home internet connections, billed by the amount of traffic you use and not by the IP. They suit light, bursty jobs on sites that block datacenter and ISP ranges. Heavy traffic gets expensive quickly, so estimate your monthly volume first.

If you are unsure, rent one address of the type you think you need, run your real task against it for a day, and look at the success rate. Because rental periods start at a few days, trying a type costs very little.
