If you’ve been putting off calling or emailing a friend or family member because you’re not sure if their number has changed, you’re not alone.

Here are four ways to easily determine if someone has updated their contact information:

-Contact their old phone service provider and ask for their new number
-Check their driver’s license or passport to see if their new address is listed


How do you know if someone changed their number on iPhone?

Check your phone records.

Assuming you have access to your phone records, you can see if the person you’re looking for has changed their phone number. Your phone company should provide you with a list of all of the phone numbers that have been called from your phone, including the date and time of the call. You can also see who called these numbers and sometimes see the phone numbers themselves in the call logs.

Compare your contacts lists.

Assuming you have a Microsoft Outlook account and you use the Contacts feature to manage your contacts, here’s a quick way to check if someone changed their phone number:

  1. Open Outlook and click on the “Contacts” tab.
  2. In the list of contacts, locate the person whose number you want to check.
  3. Right-click on the person’s name and select “Properties.”
  4. In the “Contact Properties” window, scroll down to the “Phone” section.
  5. If the person’s phone number has changed, it will be listed under a new number.

Look for changes in communication patterns.

If someone you know has recently changed their phone number, it’s likely that they’ve done so in order to increase their privacy. If you notice that your friend or family member is less likely to respond to your messages or emails, it’s likely that they’ve changed their number. Alternatively, if they suddenly start receiving a lot of calls or messages from people they don’t know, it’s likely that their number has been leaked and is now being used by someone else. If you can’t seem to track down their new number, it might be a good idea to reach out to their previous cell phone provider and see if they can provide you with the new number.

Check social media and other online profiles.

There is no one definitive way to know if someone has changed their phone number. A number of methods can be used to check social media and other online profiles, including searching for public records that may include the new number, and checking for any changes to the person’s biography or website. Additionally, it may be possible to contact the person’s previous phone carrier to inquire about any changes to their account.

Ask mutual friends or family members.

If you want to be sure that someone changed their phone number, you can ask mutual friends or family members. If they know the person well enough, they may be able to help you out. Alternatively, you can try contacting the new number directly to try and confirm that it is actually the new number.
