What is a VPN Number?
🔍 Quick answer:
"VPN number" isn't a standard term, but it usually refers to one of two things: 1) Your VPN IP address — the new IP address assigned to you by the VPN server (e.g., 185.245.85.132). This is what websites see instead of your real IP. 2) A VPN port number — the network port used by the VPN protocol (e.g., 51820 for WireGuard, 443 for OpenVPN TCP, 1194 for OpenVPN UDP). Most users don't need to worry about these numbers — VPN apps handle them automatically.
What "VPN number" could mean
Option 1: VPN IP address
When you connect to a VPN, you get a new IP address from the VPN server. This is a number like 185.245.85.132. Websites see this IP instead of your real home IP. You can see your current VPN IP by visiting whatismyip.com while connected.
Option 2: VPN port number
VPN protocols use specific network ports: WireGuard: 51820 UDP, OpenVPN: 1194 UDP or 443 TCP, IKEv2: 500 UDP. These numbers help your device connect to the VPN server. Port 443 is especially useful because it disguises VPN traffic as regular HTTPS web traffic.
Common VPN port numbers
| Protocol | Port number | Protocol type | Use case |
|---|---|---|---|
| WireGuard | 51820 | UDP | Fastest, recommended for most users |
| OpenVPN UDP | 1194 | UDP | Good balance of speed and security |
| OpenVPN TCP | 443 | TCP | Bypasses firewalls (masks as HTTPS) — most reliable |
| IKEv2/IPsec | 500, 4500 | UDP | Good for mobile devices, handles network switching |
| PPTP | 1723 | TCP | ❌ Obsolete — insecure, never use |
How to find your VPN IP address
- Connect to your VPN
- Open a browser and visit whatismyip.com
- The number displayed (e.g., 185.245.85.132) is your current VPN IP address
- If it shows your real location instead of the VPN server's location, your VPN isn't working correctly
💡 Pro tip: Most users never need to worry about VPN numbers — VPN apps handle IP addresses and ports automatically. If you're manually configuring a VPN (on a router, for example), you'll need the server IP address and port number from your VPN provider. The most common port for firewall bypass is 443 (OpenVPN TCP), which disguises VPN traffic as regular web browsing.
