# Proxy Format

PlainProxies supports different proxy credential formats, allowing you to choose the structure that best fits your software or integration requirements.

The proxy format defines how authentication details are combined with the IP address and port. This applies to all proxy types, including Residential, Datacenter, ISP, and IPv6.

**IP:PORT:USER:PASS**

This option is commonly used by tools that expect credentials as part of a single string rather than a URL.

**USER:PASS\@IP:PORT**

This format is widely supported by browsers, libraries, and most scraping frameworks.
