    You may have heard someone mention a \u201cVPN number,\u201d or you may have encountered the term in a blog post or AI-generated answer. What you won\u2019t find is a reputable VPN provider using it as an actual technical term. That\u2019s because no organization has officially designated a \u201cVPN number.\u201d<\/p>\n\n\n\n

    There are, however, plenty of real numbers associated with VPN connections, including IP addresses, port numbers, DNS server addresses, and error codes. Someone using the phrase \u201cVPN number\u201d is probably referring to one of these.<\/p>\n\n\n\n

    We\u2019ll cover every likely meaning and explain what each number does, where to find it, and whether it\u2019s integral to how your VPN works.<\/p>\n\n\n\n

    This table can help you identify what this could mean:<\/p>\n\n\n\n

    VPN category<\/strong><\/td>What It Is<\/strong><\/td>Where to Find It<\/strong><\/td><\/tr>
    VPN IP address<\/td>The public IP address of the VPN server<\/td>VPN app or IP lookup tool<\/td><\/tr>

    Most people using a commercial VPN app never need to find or enter these details. The app manages them automatically. You\u2019re more likely to encounter them when manually configuring a VPN, connecting to a workplace network, or troubleshooting a problem.<\/p>\n\n\n\n

    Your VPN IP Address Is the Most Likely Answer<\/h2>\n\n\n\n

    When someone mentions a VPN number, they\u2019re most likely talking about the public IP address of the VPN server you\u2019re connected to.<\/strong><\/p>\n\n\n\n

    Your internet provider assigns your connection a public IP address. Websites need this address to send data back to your device, but it can also reveal your approximate location and internet provider.<\/p>\n\n\n\n

    A VPN routes your traffic through a VPN server before sending it to its destination. Websites generally see the VPN server\u2019s public IP address instead of the address assigned to you by your internet provider.\u00a0<\/p>\n\n\n\n

    Some people informally call this their VPN number. The correct term is a VPN IP address or VPN server IP address.<\/strong><\/p>\n\n\n\n

    <\/p>

    Privacy primer:<\/strong> While masking your regular IP address<\/a> gives you more privacy online, it doesn\u2019t make you invisible or untraceable. Websites may still recognize you through account activity, cookies, browser fingerprinting, and other methods.<\/p><\/div>\n\n\n\n

    How to Find Your VPN IP Address<\/h3>\n\n\n\n

    You can compare your public IP address before and after connecting to the VPN:<\/p>\n\n\n\n

      \n
    1. Disconnect from your VPN.<\/li>\n\n\n\n
    2. Visit the PIA VPN IP address page<\/a>.<\/li>\n\n\n\n
    3. Record your IP address.<\/li>\n\n\n\n
    4. Connect to a VPN server.<\/li>\n\n\n\n
    5. Refresh the IP address test and compare the results.<\/li>\n<\/ol>\n\n\n\n

      The second address should be different and correspond with the VPN server location you selected.<\/p>\n\n\n\n

      An unexpected location doesn\u2019t always mean your VPN isn\u2019t working. IP geolocation databases can be inaccurate or outdated, so they may associate the server\u2019s IP address with a nearby city or a previous location.<\/p>\n\n\n\n

      If the address doesn\u2019t change at all, reconnect to the VPN and check again. You can also use an IP leak test<\/a> to investigate whether your regular public address remains exposed.<\/p>\n\n\n\n

      VPN Number Could Also Mean a Port Number<\/h2>\n\n\n\n

      A VPN port number is a real networking term. It identifies a logical communication endpoint used to send VPN traffic between your device and a server.<\/strong><\/p>\n\n\n\n

      You can think of an IP address as identifying the correct building and a port number as directing traffic to the correct door. The VPN protocol and provider configuration determine which port the connection uses.<\/p>\n\n\n\n

      Common VPN Port Numbers<\/h3>\n\n\n\n

      Different VPN protocols<\/a> often use different ports:<\/p>\n\n\n\n

      VPN Protocol<\/strong><\/td>Common Ports<\/strong><\/td><\/tr>
      OpenVPN<\/td>User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) 1194, with other ports possible<\/td><\/tr>
      Internet Key Exchange version 2\/Internet Protocol Security (IKEv2\/IPsec)<\/td>UDP 500 and 4500<\/td><\/tr>
      WireGuard<\/td>Commonly UDP 51820, but configurable<\/td><\/tr>
      Layer 2 Tunneling Protocol\/IPsec (L2TP\/IPsec)<\/td>UDP 1701, 500, and 4500<\/td><\/tr>
      Point-to-Point Tunneling Protocol (PPTP)<\/td>TCP 1723 and Generic Routing Encapsulation (GRE)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      These are common values rather than rules every VPN provider must follow. A provider or network administrator can configure a protocol to use a different port.<\/strong><\/p>\n\n\n\n

      Most people using a consumer VPN app don\u2019t need to know their VPN port number. The app selects the required protocol, server, and port in the background.<\/p>\n\n\n\n
