How to Change Phone Number on Instagram: Step-by-Step Guide (2026)

Figuring out how to change phone number on Instagram is one of those tasks that sounds simple but trips people up more often than you would expect. Maybe you switched carriers, got a new number, or realized your account is still linked to an old phone you no longer use. Whatever the reason, keeping your phone number current is important for account security, two-factor authentication, and making sure you can always recover your account if something goes wrong.

Instagram ties your phone number to several critical account functions -- login verification, password resets, and two-factor authentication codes. If the number on file is outdated, you could find yourself locked out of your own account with no way to verify your identity. This guide walks you through every method for changing, updating, or removing your phone number on Instagram in 2026, whether you are on iPhone, Android, or desktop.

Why You Should Keep Your Instagram Phone Number Updated

Before diving into the steps, it is worth understanding why this matters beyond simple housekeeping.

Your phone number on Instagram serves three primary purposes:

• Account recovery. If you forget your password or get locked out, Instagram sends a recovery code to your phone number. An outdated number means no recovery code.
• Two-factor authentication (2FA). If you use SMS-based 2FA (which many users still do), your phone number receives the login codes. A wrong number means you cannot log in from new devices.
• Identity verification. Instagram occasionally prompts users to verify their identity, especially after suspicious activity. Your phone number is one of the verification methods.
• Contact syncing. Friends searching for you by phone number will only find you if your current number is on file.

Keeping an old number linked to your account is not just inconvenient -- it is a security risk. If someone else receives your old phone number (which carriers routinely reassign), they could potentially intercept your verification codes.

How to Change Phone Number on Instagram (iPhone and Android)

The process is nearly identical on both platforms. Here is the step-by-step method using the Instagram mobile app, which is the easiest and most reliable approach.

Step 1: Open Your Profile Settings

1. Open the Instagram app and tap your profile picture in the bottom-right corner
2. Tap the hamburger menu (three horizontal lines) in the top-right corner
3. Select Settings and privacy

Step 2: Navigate to Personal Information

1. Tap Accounts Center at the top of the settings menu
2. Select Personal details
3. Tap Contact info
4. You will see your current phone number and email address listed here

Step 3: Update Your Phone Number

1. Tap your existing phone number
2. Select Change phone number (or Add phone number if none is listed)
3. Enter your new phone number with the correct country code
4. Tap Next
5. Instagram will send a confirmation code via SMS to the new number
6. Enter the 6-digit code to verify
7. Your phone number is now updated

The entire process takes about two minutes. Instagram does not require you to verify the old number before switching, which is helpful if you have already lost access to it.

How to Change Your Phone Number on Instagram from Desktop

If you prefer using a computer, you can update your phone number through the Instagram website. The desktop method is slightly different from the mobile app.

1. Go to instagram.com and log into your account
2. Click your profile picture in the bottom-left sidebar
3. Click Edit profile
4. Select Personal details under the Accounts Center section
5. Click Contact info
6. Click your current phone number and select Change phone number
7. Enter the new number and verify with the SMS code

One thing to note: some users report that the desktop interface occasionally redirects to the Accounts Center in a new tab. This is normal -- Meta has been consolidating settings across Facebook, Instagram, and Threads into a unified Accounts Center.

How to Remove Your Phone Number from Instagram

There are legitimate reasons to remove your phone number entirely. Perhaps you want to rely solely on email for account recovery, or you are concerned about privacy. Here is how to do it.

1. Go to Settings and privacy > Accounts Center > Personal details > Contact info
2. Tap your phone number
3. Select Delete or Remove
4. Confirm the removal

Important caveats before removing your number:

• You must have a confirmed email address on your account before Instagram will let you remove your phone number. The platform requires at least one contact method.
• If you use SMS-based two-factor authentication, you will need to switch to an authenticator app (like Google Authenticator or Authy) before removing your phone number, or disable 2FA entirely (not recommended).
• Removing your phone number means people can no longer find your account by searching your number in their contacts.

What to Do If You Cannot Access Your Old Phone Number

This is the scenario that causes the most frustration. You have a new phone number, but your Instagram account is still tied to the old one -- and you need the old number to log in or verify changes. Here are your options, ranked from easiest to most involved.

Option 1: Log In While Still Signed In

If you are still logged into Instagram on any device, you can change your phone number without needing the old one. Follow the standard steps above. Instagram does not re-verify the old number during the change process as long as you are already authenticated.

Option 2: Use Your Email Instead

If you are logged out and cannot receive SMS codes at your old number:

1. On the login screen, tap Forgot password?
2. Enter your username or email address (not your old phone number)
3. Select Send an email as the recovery method
4. Follow the email link to reset your password
5. Once logged in, update your phone number through settings

Option 3: Use Login Codes from an Authenticator App

If you set up an authenticator app for 2FA before losing your old number, use the app-generated codes to log in. Then update your phone number through settings.

Option 4: Use Backup Codes

When you first enabled 2FA, Instagram provided a set of backup recovery codes. If you saved these (and you should always save them), you can use one to bypass the SMS verification.

Option 5: Contact Instagram Support

If none of the above options work:

1. On the login screen, tap Get help logging in
2. Enter your username, email, or phone number
3. Tap Need more help? at the bottom
4. Follow the prompts to submit a support request
5. Instagram may ask you to verify your identity with a selfie video

Be patient with this process. Instagram support responses can take anywhere from a few hours to several days, and in some cases longer.

How to Change Your Phone Number Without Losing Two-Factor Authentication

Two-factor authentication is one of the best ways to protect your Instagram account, and changing your phone number does not have to disrupt it. The key is to switch your 2FA method before changing your number.

1. Go to Settings and privacy > Accounts Center > Password and security > Two-factor authentication
2. Enable Authentication app and set it up with Google Authenticator, Authy, or similar
3. Once app-based 2FA is active, update your phone number through Contact info
4. After the new number is confirmed, you can optionally re-enable SMS as a backup method
5. Save your new backup codes

If you already lost access to your old number, use a backup code or your email to log in first, then follow the same steps above.

Pro tip: always use an authenticator app as your primary 2FA method instead of SMS. Authenticator apps are not tied to a phone number, so changing carriers or numbers never affects your ability to log in.

Common Issues When Changing Your Instagram Phone Number

Even with clear steps, some users run into problems. Here are the most common issues and their fixes.

"This phone number is already in use"

Instagram requires each phone number to be unique across accounts. If you see this error, the number is linked to another Instagram account -- possibly an old account you forgot about. You will need to remove the number from the other account first, or use a different number.

Verification code not arriving

• Check that you entered the correct country code
• Make sure your phone can receive SMS (not just iMessages or data-based messages)
• Wait a few minutes -- codes can be delayed during high traffic periods
• Tap Resend code if available
• Try switching to WhatsApp verification if Instagram offers it as an option

"Something went wrong, please try again later"

This generic error usually means Instagram's servers are temporarily overloaded or your app needs updating. Try these fixes:

1. Force close the app and reopen it
2. Update Instagram to the latest version
3. Clear the app cache (Android: Settings > Apps > Instagram > Clear Cache)
4. Switch between WiFi and mobile data
5. Try again in a few hours

Changes not saving

If your phone number update seems to go through but reverts, make sure you are completing the SMS verification step. The change is not finalized until you enter the confirmation code.

How Changing Your Phone Number Affects Your Instagram Account

A common worry is that changing your phone number will somehow reset your account or lose your content. Here is what actually happens -- and what does not.

Things that stay exactly the same:

• All your posts, Reels, Stories highlights, and saved content
• Your followers and following list
• Your DMs and message history
• Your username, bio, and profile information
• Your linked Facebook/Threads accounts
• Your verification badge (if applicable)

Things that change:

• The phone number used for SMS-based 2FA codes
• The phone number used for account recovery
• The number people can use to find your account via contact syncing

In short, changing your phone number is purely a contact and security update. It has zero effect on your content, audience, or engagement metrics. If you are growing your Instagram presence -- whether organically or with a boost from services like SocialzAI -- your growth trajectory is completely unaffected by a phone number change.

Frequently Asked Questions

Can I have two phone numbers on one Instagram account?

No. Instagram only allows one phone number per account. However, you can have both a phone number and an email address linked to the same account, which gives you two recovery methods. If you manage multiple accounts, each one needs a unique phone number.

Will changing my phone number log me out of Instagram?

No. Changing your phone number does not log you out of any device where you are currently signed in. Your active sessions remain unaffected. However, if you use SMS-based two-factor authentication, you will need the new number to log in on any new devices going forward.

How often can I change my phone number on Instagram?

Instagram does not impose a strict limit on how often you can change your phone number, but making frequent changes in a short period may trigger temporary security restrictions on your account. If you need to change it, once is usually enough -- there is no reason to do it repeatedly.

Can I use a VoIP or Google Voice number for Instagram?

Instagram has become increasingly strict about blocking VoIP and virtual numbers. While some Google Voice numbers still work, many users report that Instagram rejects them during verification. For the most reliable experience, use a standard mobile carrier number.

What happens to my Instagram if my old phone number gets reassigned to someone else?

If a carrier reassigns your old number and you still have it linked to your Instagram, the new owner of that number could potentially receive your verification codes. They would still need your password to log in, but this is a significant security concern. This is exactly why you should update your number as soon as it changes and use an authenticator app for 2FA instead of SMS.

I changed my number but Instagram still shows the old one. What do I do?

This usually means the verification step was not completed. Go back to Settings and privacy > Accounts Center > Personal details > Contact info and check which number is currently listed. If it is the old one, start the change process again and make sure you enter the SMS verification code when prompted.
