How to Use Phone Number Twice on Facebook

Let’s assume you’ve tried to set up multiple Facebook accounts for different purposes, like managing personal connections and business profiles, and you want to use the same phone number for verification on each. Unfortunately, Facebook’s policies make this tricky, as they restrict the use of one phone number across multiple accounts due to security and anti-spam measures. This often leaves users confused about how to manage both accounts smoothly. Since Facebook doesn’t provide specific instructions for scenarios like these, it’s essential to understand best practices to work around this limitation while staying compliant with their guidelines. Here, we’ll explore some helpful approaches and precautions for using the same phone number across two Facebook accounts.

Can You Use the Same Phone Number for More Than One Facebook Account?

Generally speaking, Facebook's system prohibits using the same phone number for more than one account. The main purpose of this security feature is to guarantee that every user has distinct and authenticated contact details. Facebook may block or replace the number on the original account if you attempt to add the same number to a second account. By utilizing temporary numbers or merely enabling two-factor authentication (2FA) on one account, some users have been able to effectively handle this. Think about other options, including using a separate email address or creating two accounts with distinct verification processes, if you require several accounts with the same number.

How Do I Add a Second Phone Number to My Facebook Page?

One practical strategy to handle contact for both personal and professional purposes is to add a second phone number to a Facebook page. Go to your Page's Settings tab, click on Contact Information, and then choose Add Another Phone Number to add another number. Enter the new number, then use the code Facebook supplied to verify it. This gives administrators a more flexible approach to control the page and lets them swap between numbers for notifications. To avoid login issues, make sure the phone isn't connected to any other personal Facebook accounts.

How Do I Add My Phone Number to Facebook Two-Factor Authentication?

Adding your phone number to Facebook’s two-factor authentication (2FA) helps secure your account with an extra layer of protection. To set this up, go to Settings, select Security and Login, and find Two-Factor Authentication. Choose to enable 2FA via SMS, and enter your phone number. Facebook will send you a code to verify the number, ensuring it’s linked to your account for future logins. This simple step keeps your account more secure, as each login attempt will require both your password and a code sent to your phone.

How to Get 2 Facebook Accounts on One Phone?

Either the main Facebook app and Facebook Lite or a browser and the app may be used to manage two Facebook accounts on a single phone. If the program has a "Switch Account" function that enables fast access across accounts, using it is an additional choice. Because they enable the same application to run in several instances, third-party programs like Parallel Space are also useful to some users. To prevent any security threats or login issues, exercise caution when utilizing third-party Facebook apps.

How to Use Phone Number Twice on Facebook?

Although Facebook normally prohibits using the same phone number for numerous accounts, there are a few ways to try to get around this restriction. Here's a tutorial on how to handle this and some advice on how to keep Facebook from flagging you.

1. Understand Facebook’s Policy on Phone Numbers

• Facebook’s system is designed to allow only one account per phone number for security reasons. This prevents fake accounts and spam, so if you try to add a phone number that’s already in use, Facebook will likely reject it.
• Be aware that Facebook strictly enforces this rule to protect user accounts, and any workarounds might carry some risk if not handled carefully.

2. Use Email as a Primary Contact on the Second Account

• One way to manage two accounts is by using an email address as the primary contact on one of the accounts instead of a phone number.
• How to Set It Up: Go to Settings on the second account, select Contact Info, and add an email address as your primary contact instead of your phone number.
• This way, each account has a unique identifier—one with a phone number and the other with an email—helping you avoid Facebook’s restrictions on using the same number.

3. Set Up Two-Factor Authentication on Only One Account

• If you require two-factor authentication (2FA) for enhanced security, set it up only on one account using your phone number.
• For the other account, use a two-factor authentication app instead of SMS verification, allowing you to bypass the need to use your phone number twice.
• Setup Tip: Go to Security and Login Settings, select Use two-factor authentication, and choose Authentication App as your 2FA method on the second account.

4. Use a Temporary or Secondary Number for Verification

• If you need to verify both accounts with a phone number temporarily, you could use a secondary number (like a Google Voice number) for the setup.
• After setting up, you can switch to an email for the second account’s primary contact to avoid future issues. Just be sure to update any two-factor authentication settings accordingly.

5. Alternate Between Numbers When Necessary

• If you’re unable to use the same number on two accounts permanently, consider using one number temporarily for verification and then switching the primary contact to an email.
• Switch Steps: Go to Settings > Personal Information > Contact Info, and change the phone number on the second account to an email.

6. Avoid Logging into Both Accounts on the Same Device

• Logging into multiple accounts with similar credentials on the same device can trigger Facebook’s security alerts. Using different devices, or even different browsers, for each account can reduce the chance of linking.
• Alternatively, you can use a reliable proxy service to separate login sessions if you’re using both accounts for different purposes.

7. Consider Using Proxies for Multiple Accounts

• If you manage multiple Facebook accounts, proxies can help avoid detection by routing each login through a unique IP address.
• How Proxies Help: Proxies can provide an additional layer of anonymity by making it appear as if each account is being accessed from a separate device or location, reducing the likelihood of Facebook associating the accounts.

8. If One Account is Flagged, Remove the Phone Number

• If Facebook flags one account due to duplicate contact info, remove the phone number from one of the accounts immediately.
• Removal Steps: Go to Settings > Contact Info and delete the phone number from the flagged account to avoid further complications.

Same Phone Number for 2 Accounts, But Can Only Log Onto 1, How to Solve?

Try accessing the accounts using their individual email addresses first if you're having trouble getting in since the same phone number is linked to two accounts. If the phone number is the primary contact on both accounts, Facebook's algorithm can give one account priority over the other. Choose "I can't access my account" under Account Recovery, then enter the email address rather than the phone number. If issues persist, consider removing the phone number from one account and linking it solely to the main account, or try using proxies to distinguish between login sessions.

Use Proxies to Solve the Problem

Managing several Facebook accounts on the same device may benefit from the use of proxies. By allowing you to generate unique IP addresses for every account, proxies lessen the likelihood that Facebook will connect them. This method keeps Facebook from reporting repeated logins as suspicious behavior, which is particularly helpful if you have accounts for both personal and professional use. To ensure reliability, set up a trustworthy proxy service, log in to each account independently using the allotted IP, and refrain from switching frequently.
