Accessing Facebook is not always easy, especially when you encounter geographical restrictions or need to manage multiple accounts simultaneously while ensuring security. Many of you, particularly advertisers or Facebook marketers, have surely experienced the headache of having an account blocked for unclear reasons. In this context, a Proxy for Facebook Ads has become an indispensable tool to protect online privacy, increase stability, and enhance security for over 3 billion monthly Facebook users. Let’s explore reputable proxy providers with Optimal Agency that you can trust to optimize performance and security when operating on this platform.
Proxy is more suitable for Facebook Ads than VPN. Why?
When it comes to running Facebook ads, we understand that maintaining stability and security for the ad account is paramount for advertisers. Many people often wonder whether to choose a Proxy or a VPN to hide their IP address and manage multiple accounts simultaneously. However, the reality shows that Proxy is significantly superior to VPN in the Facebook advertising environment. Let’s analyze in detail why.

Proxy is better for running Facebook ads
When it comes to operating multiple ad accounts, a proxy acts as a “shield” that helps advertisers avoid the risk of account locking. Here are the reasons why a proxy is considered the smarter and safer choice when deploying ad campaigns on Facebook.
IP address isolation
When running multiple ad accounts simultaneously, each account must have a distinct IP address. A proxy allows you to use a dedicated IP for each account, completely isolating login and advertising activity.
For example, if you are operating 10 different ad accounts for various brands, each account will have its own proxy. As a result, Facebook will be unable to detect that they all belong to the same manager. This helps prevent account linking, one of the leading causes of account suspension or disablement.
Reduced risk of blocking
Facebook can detect VPN IPs very quickly because most of these addresses are publicly shared and used by thousands of people. Conversely, a Residential Proxy, which is a real IP address from a household user, is considered more legitimate and natural in Facebook’s view. Therefore, when we use a residential proxy, the risk of account restriction or locking is significantly reduced. For instance, if you are running an ad campaign in the US, you can select a proxy with an IP address in California, making the account appear as if it is operating in the correct geographical area. This makes the account more trustworthy in the eyes of Facebook’s review system.
More effective account management
With a proxy, you can manage multiple ad accounts simultaneously without the risk of overlap. Each account is bound to a separate proxy, ensuring complete separation of login data, cookies, and access history. We, who have managed hundreds of ad accounts, have found that using a proxy not only optimizes the workflow but also helps build a professional, secure, and stable advertising system. When Facebook sees each account operating from a different location, it will evaluate this as natural behavior, thereby limiting the risk of account locking.
Why VPN is not ideal for running Facebook ads
Many people think that a VPN can provide similar effectiveness to a proxy, but the reality is otherwise. Although a VPN helps hide the IP address, its operating mechanism makes ad accounts easier for Facebook to detect and block. Let’s find out in detail why a VPN is not the optimal choice for professional advertisers.
Shared IPs
A VPN works by redirecting all device traffic through an intermediary server with a single IP address. The problem is that this IP is often shared and used by hundreds or even thousands of other people. This leads to a serious risk: if another user on the same IP is blocked by Facebook, all other users on that IP can also be affected. For example, if you are running legitimate ads but someone on the same VPN server engages in fraudulent behavior, Facebook’s system can still flag and disable your account.
Easily detected by Facebook
Facebook has an extremely sophisticated monitoring system to detect anonymous or suspicious behavior. When you use a VPN, Facebook will easily recognize that your IP address is a virtual IP, which does not correspond to your real location. This behavior makes Facebook assume you are concealing your true identity or intentionally manipulating the ad system, leading to warnings, ad restrictions, or even the locking of the entire Business Manager account. That’s why many advertisers using a VPN often encounter the status “Account suspended due to unusual activity.”
Is Proxy truly important for Facebook advertisers?

In today’s Facebook advertising market, managing multiple accounts, running campaigns for various businesses, or advertising in different geographical areas is becoming more complex than ever. Facebook’s fraud and anomaly detection system is increasingly stringent, so you need tools that help reduce your operational footprint and keep campaigns running stably. A proxy is one of those tools, especially when you want to operate without accidentally triggering warnings or getting accounts locked.
When you manage ads for multiple clients or multiple accounts simultaneously, using the same IP address can lead to serious consequences. Facebook can recognize unusual activity when one IP accesses several different accounts, and this can lead to account suspension or disablement. Therefore, we advise you to use a proxy to separate the access sources. For example, if you are running an account for a client in the United States but operating from an office in Vietnam, using a local proxy in the US will help Facebook recognize the traffic as originating from the correct area, reducing the risk of being flagged as anomalous behavior.
Overcoming geo-restrictions and ad limitations
A common situation many advertisers face is wanting to run a campaign targeting one country while the operational team is in another. If you do not use a proxy, Meta may limit ad spend or even prevent some ads from running due to detecting a location discrepancy. Using a proxy can help you run ad checks as if you were in the actual target market. For example, when we need to check the ad display in the US for a real estate campaign, we connect through a proxy located in the corresponding state to ensure the real display experience and check the localized landing page.
Proxy for GH campaigns and verification work
Whether your goal is to manage grey hat (GH) ad accounts, operate multiple profiles for clients, or simply verify your ads in multiple countries, a proxy is a practical tool for doing so more safely. Many advertisers working in the grey hat market still need to minimize their technical footprint to avoid being detected by Facebook’s automated system. We always recommend applying a dedicated proxy for each account instead of using a single proxy for multiple accounts.
Security benefits and reduced risk of account ban
Using a proxy correctly helps conceal your real IP address, reducing the risk of detection and ensuring your campaign is not interrupted. Although you technically could use your personal IP address, this poses a major risk. If multiple ad accounts share one IP, the likelihood of those accounts being disabled increases significantly. A proxy allows IP segmentation for each account, providing an additional layer of security and helping to maintain the credibility of the ad account.

Frequently Asked Questions
Technically, you can use a VPN to access Facebook from a different country to run ads. However, this may violate Facebook’s terms of service and advertising policies, and you need to consider carefully:
Facebook Ads is designed to target specific regions and audiences based on the ad account’s location settings. Attempting to use a VPN to run ads from other countries may violate Facebook’s policies.
When using a VPN to change location, you may encounter difficulties with payment and billing. Furthermore, it can affect the integrity and transparency of advertising activities.
The success of a Facebook Ads campaign depends on relevant ad content and precise target audience selection. Using a VPN to run ads in a country that is not the target market will lead to budget wastage.
