Open Snapchat and go to your profile settings

To change your birthday on Snapchat, start by opening the app and tapping your profile icon in the top left corner. This takes you to your profile page, where you'll see your username, display name, and a gear icon in the top right. Tap that gear icon to enter your account settings.

Once you're in settings, scroll down until you see the "Username" section. Just below that, you'll find "Birthday" listed as an editable field. This is where Snapchat stores the birth date you provided when you created your account.

Key Takeaways

  • Your birthday is found in Snapchat's account settings, accessible through your profile icon and the gear icon.
  • Snapchat allows you to change your birthday once per year, so choose your update carefully.
  • The app requires you to enter your birthday in the format MM/DD/YYYY to save the change.
  • If you cannot find the birthday field or the change won't save, sign out completely and sign back in to refresh your account.

Tap the birthday field and enter your new date

When you tap on the "Birthday" field, a date picker will appear. You can scroll through the months and years to find the correct date, or you can type the date directly if your phone allows it. Snapchat requires the format MM/DD/YYYY — for example, 03/15/1990 for March 15, 1990.

Double-check the date before you confirm it. Snapchat limits birthday changes to once per year, so if you make a mistake, you'll have to wait twelve months before you can change it again. Once you're certain the date is correct, tap the checkmark or "Done" button to save your change.

Understand Snapchat's one-change-per-year rule

Snapchat enforces a strict policy: you can change your birthday only once every twelve months. This rule exists to prevent account abuse and protect younger users. If you've already changed your birthday recently, the app will show you when you're next able to make another change.

If you need to correct a birthday you just entered and you've already used your one annual change, you'll need to contact Snapchat support. Go to the Help section in settings, select "Contact Us," and explain that you entered your birthday incorrectly. Support can sometimes override the one-change limit in cases of genuine mistakes, but there's no may provide they will.

What happens if the change won't save

Sometimes the birthday field won't accept your input or the change disappears after you close settings. The most common fix is to sign out of Snapchat completely, then sign back in. This refreshes your account connection and often resolves temporary glitches.

If signing out and back in doesn't work, try uninstalling and reinstalling the app. Make sure you remember your username and password before you uninstall — you'll need them to log back in. After reinstalling, open the app, log in, and try changing your birthday again. If the problem persists, contact Snapchat support through the Help section in settings.

Why Snapchat asks for your birthday

Snapchat collects your birthday for several reasons. The app uses it to verify you're old enough to use the platform — Snapchat's terms of service require users to be at least 13 years old. Your birthday also determines which features you can access; some filters and functions are restricted for younger users.

Additionally, Snapchat uses your birthday to send you a birthday notification on your profile, which friends can see. This is optional — you can turn off birthday notifications in your privacy settings if you prefer not to share that information with your friends list.

Changing your birthday on the web version

If you're using Snapchat on a computer through the web version, the process is slightly different. Log into your account at snapchat.com, then click your profile icon in the top right corner. Select "Settings" from the dropdown menu, then look for "Birthday" in your account information section.

The web version uses the same MM/DD/YYYY format and enforces the same one-change-per-year limit. After you enter your new birthday and click "Save," the change will sync to your mobile app within a few minutes. If it doesn't appear on your phone right away, close and reopen the Snapchat app.

Frequently Asked Questions

Can I change my birthday more than once a year?

No. Snapchat limits birthday changes to once per calendar year. If you've already made a change, you'll have to wait until the anniversary of that change before you can update it again. Contact support if you made a genuine mistake and need an exception.

What if I entered the wrong birthday when I created my account?

You can change it using the same process described above — tap your profile, go to settings, find the birthday field, and enter the correct date. You have one change per year, so use it carefully. If you need to change it again before a year has passed, reach out to Snapchat support.

Will changing my birthday affect my Snapchat memories or streaks?

No. Changing your birthday does not delete or alter any of your saved snaps, memories, or streaks. It only updates the birth date associated with your account. Your friends will still see your updated birthday on your profile once the change saves.

Why does Snapchat need my real birthday?

Snapchat uses your birthday to verify you meet the minimum age requirement of 13 years old and to control which features you can access. Some filters and functions are age-restricted. Your birthday also powers the birthday notification feature that lets friends know it's your special day.

What should I do if the birthday field is grayed out or won't let me edit it?

If the field appears locked, you've likely already used your one annual change. Sign out completely, wait a few minutes, and sign back in to see if the restriction has lifted. If it's still locked and you haven't changed it in over a year, contact Snapchat support for help.
