If you want to change your age on Instagram, there are a few ways to go about it. The first option is to go to your account settings and select “Account Details.” From here, you can find the “Age” field and change it to the new age you want. If that’s not an option for you, you can also use a third-party app like AgeID or TrueAge. Both of these apps require you to take a picture of your ID card or driver’s license and then input that information into the app. Once you have done this, your new age will be reflected on Instagram. ..
