There’s no official “VPN number,” yet many people use the term in various contexts. Most often, people mean the IP address you get when you connect to a VPN server. However, port numbers, server counts, and even phone numbers can factor into a VPN “number.”
These numbers (and more) serve different purposes. Some help establish your VPN connection, others identify where your traffic seems to come from, and some have nothing to do with VPNs at all. Knowing the difference can make it easier to find what you actually need.
Quick Guide: What Does “VPN Number” Actually Mean?
When people search for “VPN number,” they often confuse it with several other technical concepts:
- VPN IP address: The public IP address websites see when you’re connected to a VPN server. It replaces your usual public IP address from the websites’ perspective. It’s often referred to as a “VPN number.”
- Phone number: The number associated with your mobile phone service. A VPN doesn’t change it or hide it when you make regular calls or send texts.
- VPN account number: This would be a numerical identifier associated with your VPN subscription. You don’t need one to connect to CyberGhost VPN, which uses account login credentials.
- VPN port number: This identifies a network endpoint used to send traffic to the appropriate service. VPN protocols use ports to establish connections, but they don’t identify you personally.
What Is a VPN and How Does It Work?
A virtual private network (VPN) is a service that encrypts your internet traffic and routes it through a VPN server, helping protect your data and hide your usual IP address. It creates a secure VPN tunnel between your device and the server, using a VPN protocol to establish and manage the connection.
Your ISP gives your connection a public IP address, which websites can use to gather your approximate location. But when you connect to a VPN, the same websites can only see the IP address from the VPN server instead. At the same time, VPN encryption helps prevent your ISP and others monitoring the network from reading traffic inside the tunnel.
What Is a VPN Number? Here’s What Different Numbers Refer To
Let’s break down the numbers relating to VPN use to see which one you’re looking for.
IP Addresses
An IP address identifies a device or network connection and helps direct internet traffic to the right destination. It can come in one of two formats: IPv4, which uses four groups of numbers (such as 192.168.1.1), and IPv6, which uses a longer combination of numbers and letters (such as 2001:db8::1). A VPN IP address is what most people refer to when talking about a “VPN number.”
To check your VPN IP address:
- Connect to a VPN server.
- Check whether your VPN app displays a current VPN IP address.
- Alternatively, visit an IP-checking website to see the public IP address websites see.
Your VPN IP address may change when you reconnect or switch servers. CyberGhost VPN has a global network of servers, giving you a range of locations to choose from. Some VPNs also don’t handle IPv6 traffic properly, potentially exposing your real IPv6 address even when it protects your IPv4 traffic. CyberGhost VPN blocks IPv6 traffic while connected to help prevent these leaks.
Shared vs Dedicated IPs
Several VPN subscribers can use the same shared IP address, while a dedicated IP address is for exclusive use. Both are regular public IP addresses, but they offer different advantages:
- Shared IP: Multiple people use the same VPN IP address, making it harder to associate activity with one person based on the IP alone. The downside is that websites may restrict the address if other users have abused it.
- Dedicated IP: You get an exclusive IP address that generally stays the same over time. This is useful for accessing services that require a consistent IP, such as certain work systems or banking platforms.
The choice between shared and dedicated IPs boils down to your individual needs and priorities. If you prioritize extra privacy and cost-effectiveness, a shared IP is a great choice. If you need a stable, unique online identity for specific purposes, a dedicated IP might be the way to go. CyberGhost VPN offers both options. By default, CyberGhost VPN assigns a shared IP, but you can also get a dedicated IP as an add-on feature.
VPN Protocols
VPN protocols are sets of rules that determine how your device establishes and maintains a secure connection with a VPN server. They aren’t VPN numbers, but their names often appear in VPN settings alongside technical connection details. Protocols prioritize speed, security, and stability in varying ways.
CyberGhost VPN supports three protocols:
- OpenVPN: A widely used, open-source protocol known for its security and flexibility. It supports both TCP and UDP connections.
- WireGuard®: A modern, lightweight protocol designed for fast connections and efficient performance.
- IKEv2/IPsec: A protocol combination known for maintaining stable connections when switching between networks, such as moving from Wi-Fi to mobile data.
You don’t have to choose one manually. CyberGhost VPN can select the best protocol for your device and connection, although you can change it in the app settings.
Port Numbers
A port number helps direct network traffic to the correct service or application. VPN protocols can be associated with certain ports, but they don’t have one fixed port number in every situation. The port a VPN uses can vary depending on the protocol, provider, implementation, and configuration.
Common VPN port numbers include:
- OpenVPN: UDP 1194 or TCP 443
- WireGuard®: UDP 51820 (often used but configurable)
- IKEv2/IPsec: UDP 500 and 4500
- L2TP: UDP 1701
In most cases, your VPN app handles protocol and port settings, choosing an available configuration to help establish a stable connection without requiring manual setup. If you experience connection problems, switching protocols may help. The app may also let you choose a protocol yourself.
VPN Server Numbers
A VPN server number refers to how many servers a VPN provider operates across its network. Most premium VPNs have servers in multiple countries and cities, giving you many locations to connect to.
However, server count is only one of the metrics to measure a VPN, and a bigger number doesn’t guarantee better performance. Server locations, capacity, and connection speeds all play a part. It’s best to look at everything together and test a VPN service yourself to see how well a provider performs.
DNS Server Number
A DNS server translates website names into IP addresses, so your device knows where to connect. DNS servers have their own IP addresses, which you might come across in your network settings or when running a DNS leak test.
When you’re connected to a VPN, your DNS requests usually go through the encrypted VPN tunnel to private DNS servers. This helps prevent your ISP from seeing the websites you’re looking up and reduces the risk of DNS leaks.
Error Codes
If you encounter issues while using a VPN, it might display specific error codes. Your VPN software displays these numerical or text codes to tell you what’s wrong. Every unique code links to a specific type of problem, and it helps VPN developers (and sometimes you) figure out a solution. Examples include “Error 691: Incorrect username or password” and “Error 800: Cannot establish a connection to the VPN server.”
VPN Phone Number
A VPN doesn’t give you a new phone number or hide your existing one. It masks your public IP address, not your mobile number. People you call or text through your regular mobile service can still see your number, even when you’re connected to a VPN. If you want to keep your phone number private, you’ll need a separate solution, such as a secondary number or a calling service that doesn’t share your number with recipients.
VPN Customer Service Number
When things go wrong, or you have burning questions about your VPN, the most important number isn’t an IP address or a port number — it’s the VPN’s customer service number.

Get to Know “VPN Numbers” for What They Really Are
There’s no single number that makes your VPN tick. What people call a “VPN number” could be a VPN IP address, a port number, a server address, or even an error code. Knowing which one you’re looking for makes it much easier to find the right setting, understand your connection, or troubleshoot when something goes wrong.
You don’t need to keep track of most of these numbers yourself. CyberGhost VPN handles the technical details of establishing your connection and lets you choose a server location to change your public IP address. You can try it for yourself with a 45-day money-back guarantee (14 days for monthly plans) to see if the service is right for you.
FAQ
Where can I find my VPN number?
If by “VPN number” you mean the IP address your VPN gives you, you can usually see it in the VPN app after connecting or check it with an IP lookup tool. You may also find VPN server and connection details in your app’s settings.
What is a VPN number used for?
It’s a misconception that VPNs have a single “number.” Instead, VPNs use multiple numbers for different purposes: IP addresses help mask your location, and port numbers direct traffic types. The VPN server location determines the apparent location associated with your VPN IP address. Together, these numbers protect your privacy without you having to manage them.
What is my VPN port number?
Your VPN port depends on the protocol and configuration you’re using. For example, OpenVPN typically uses UDP port 1194 or TCP port 443, while IKEv2/IPsec normally uses UDP ports 500 and 4500. Most VPN apps choose the appropriate port for you.
Why does my VPN IP address keep changing?
Many VPNs use shared IP addresses, so you may receive another IP address when you reconnect or switch servers. This is normal. If you need a consistent IP address, some VPN providers offer a dedicated IP that stays assigned to you.
