If you‘ve recently been the victim of identity theft or phone number hacking, one of the best things you can do to protect yourself is get a new phone number. Changing your number is critical to block scammers and hackers from continuing to access your accounts and exploit your information.

In this comprehensive guide, we‘ll walk through step-by-step how to change your phone number with your carrier and update it across all your major accounts, including Google, Facebook, Instagram, Twitter, and more. We‘ll also provide key tips to further secure your accounts, watch out for phone scams, and take control of your identity after it‘s been compromised.

Why Changing Your Phone Number is Crucial After Identity Theft

Your phone number is a key piece of personal information that identity thieves target. Here are some of the main reasons getting a new number is so important after you‘ve fallen victim:

  • Stops account access: Many accounts use your phone number for two-factor authentication and password reset links. If criminals still have access, they can get into your accounts.
  • Prevents fraudulent activity: Thieves can use your number to open new accounts or take over existing ones. A new number cuts off their access.
  • Protects from repeat targeting: Once compromised, you‘re vulnerable to repeat attacks or hackers selling your info. A new number helps prevent this.
  • Improves peace of mind: Knowing your number is secure will help restore a sense of safety after the violation of identity theft.
  • Blocks SMS scams: Scammers also use numbers to send phishing links and texts. A new number stops these smishing attempts.

According to a 2022 identity theft study by NordVPN, 68% of victims had their phone numbers and SIM cards compromised. Additionally, 36% said hackers used their number to access financial accounts or commit other fraud.

This highlights how important your phone number is to your identity security. Let‘s look at how to change your number and update it across accounts.

Step 1: Getting a New Number from Your Carrier

Start by contacting your cell phone carrier to request a new wireless number. Here are quick overviews of how the process works with major providers:

  • AT&T: Get one free change within 30 days. After that, a $36 fee applies. Change online, in the app, or via customer service.
  • T-Mobile/Sprint: Receive one free change, then pay $15 per change after that. Contact T-Mobile support to request a new number.
  • Verizon: No limit disclosed on number changes. Avoid the $15 fee by changing in the app instead of through customer service.

When getting a new number, be aware it may temporarily impact services like voicemail, caller ID, and text messaging for a few days.
