How To Find Someone's Birthday Online & Off Without Asking in 2026

You want to know their birthday. But asking feels weird.

Maybe it's a coworker you'd like to surprise. A long-lost cousin you're trying to reconnect with. Someone from high school whose cake you missed by a decade. Whatever the reason, you don't want to tip your hand — you just want the date.

Here's the thing: you don't have to ask.

Birthdays hide in plain sight. Public records. Old social media posts. That one Facebook friend who commented "Happy 30th!" back in 2019. A mutual friend who'd gladly help if you framed it right. The information is already out there, and you just need to know where to look.

We built TruthFinder for exactly this kind of search. Our People Search pulls from billions of public records and social profiles to surface details like birthdays, full names, past addresses, and more — often in a single report.

But TruthFinder isn't the only route. Below, you'll find every method that works in 2026, from social media sleuthing to public records to the one casual question that usually gets the answer.

The date you're looking for? It's closer than you think.

Online Methods For Finding Someone's Birthday

Thankfully, the internet has several ways to find someone's birthday with little to no effort. Let's have a look at some of the best ways to figure out when someone was born using the internet.

Social Media

Over 4.62 billion people in the world use some form of social media. Chances are if you’re looking for someone's birthday, they probably have an account on one of these platforms. Many users list their birthday information on their profiles. If you don't know where there social media account are, you could always locate them with their phone number. Let's have a look at how to find someone's birthday on some of the most popular social media sites.

How To Find Someone's Birthday On Facebook

1. Log into your Facebook account.
2. Enter the name of the person you're looking for into the search bar at the top of the page.
3. Once you reach the individual's profile page, scroll down to the "About" section which is the most common place to list a DOB.
4. However, if they have set the privacy settings to "Friends only" you'll need to befriend them on Facebook to view this section.

If the person has their Facebook account set to "Public" you will may be able to see their birthday without needing your own Facebook account. If you don't have an account, try running a Google search for the person's name in quotes + Facebook like this: "John Smith" Facebook. This should help you locate their page without needing a Facebook account of your own.

How To Find Someone's DOB On Twitter

1. Search for the person's Twitter account: Use the Twitter search bar to search for the person's Twitter account or run a Google search for the person's name + Twitter.
2. Check their profile: Once you find their account, check their profile for any information that may indicate their birthday. This could be in their profile bio or in the tweets they have shared. If the person has their profile set to private, you will need to follow them and be approved.
3. Look for birthday tweets: Search their Twitter feed for any tweets that mention their birthday or contain the hashtag #birthday.
4. Check for birthday greetings from others: Check the replies to their tweets to see if anyone has wished them a happy birthday.

Like Facebook, Twitter allows the user to set their profile to either "Public" or "Private". You will not need a Twitter account to view someone's profile as long as their profile is set to "Public".

How To Find Someone's Birthday On Instagram

Finding someone's birthday on Instagram can be quite tricky, as Instagram doesn't have a dedicated field for users to share their birthdays. However, here are a few ways you can try to figure out when someone was born:

1. Check their bio: Some people choose to include their birth date in their bio, which can be found on their profile page.
2. Look at their posts: If someone has posted about their birthday, or if they have posted photos from their birthday celebration, you may be able to find it by searching through their posts.
3. Check tagged photos: If someone has been tagged in photos related to their birthday, that could be another clue as to when they were born.

Similar to Facebook and Twitter, Instagram allows users to set their profiles to "Public" or "Private". To view someone's profile when it is set to private, you will need to have an Instagram profile and follow them.

How To Find Someone's Birthday On Snapchat

Snapchat doesn't have a direct feature that allows you to see someone's birthday on their profile, but there are a few ways to go about finding someone's birthday on Snapchat:

1. Check Their Snapchat Birthday Cake: If someone has added their birthday to their Snapchat account, a birthday cake icon will appear next to their name on their special day. Keep in mind, if the person entered a fake birthday when signing up, this will be incorrect.
2. Look Through Their Snapchat Story: If the person has posted a birthday celebration story on Snapchat, you might be able to get an idea of when their birthday is.
3. Look For Linked Social Media: If the person has linked their social media profiles, you may be able to find their birthday information on their linked Instagram or Facebook profiles.

Because the birthday information is part of the user's profile, you will need a Snapchat account to view someone's account.

How to Find Someone's Birthday on LinkedIn

1. Log in to your LinkedIn account or sign up for an account.
2. Search for the person: Use the search bar to search for the name of the person you are looking for. When the results appear, select the correct profile.
3. Check the person's profile information: Once you have found the person's profile, scroll down to their “About” section to see the information they have shared publicly. If the person has added their birthday to their profile, you will see it listed under the “Contact Info” section.

Like other social media platforms, you may be able to see the person's profile if it is set to “Public”, but some information may be hidden if their profile is set to private.

Public Records Search

Using an online public records search is a great way to locate someone's birthday because you'll have a wealth of information at your fingertips. Using a search like TruthFinder's People Search allows you to access millions of public records in a matter of minutes which may include someone's birthday. Think of it as a birthday lookup.

Use A Google Search To Locate Other Online Resources

Google is a great last resort option to locate someone's birthday online. As we mentioned earlier, you can use Google or any other search engine to locate public social media profiles, but what are some other ways to use Google to locate a person’s date of birth? Let's have a look.

How To Look For News Articles That May Include Someone's Birthday

1. Search for the person's name along with the words "birthday" or "birth date" in a search engine such as Google.
2. Check local and regional news websites for any articles about the person. Oftentimes, local news articles will mention a person's birthday in a story.
3. Search for the person's name in the archives of major news outlets, such as The New York Times or The Washington Post.
4. Look for articles that mention the person's achievements or milestones, such as graduation, retirement, or promotion, as they may also mention the person's birthday.

This method is probably best suited if you live in a smaller town opposed to a large city like New York, but it can't hurt.

How To Locate Obituaries

If the person you're searching for is no longer alive, you may be able to locate their birthday through an online obituary.

1. If the obituary is recent, you may be able to find it by searching for the person's name along with the word "obituary" in a search engine.
2. Look for articles related to the person's death or public online obituaries on sites like Legacy.com within the results.

Offline Methods For Finding Someone's Birthday

If you've hit a roadblock in your online search, you may want to try an offline method. Here are some ways you can use offline methods to search for someone's birthday.

Ask Mutual Friends & Family Members

This is probably the easiest method of all to find out when someone was born. If you have mutual friends or communicate with their family members, simply reach out to them and ask. Keep in mind that not everyone may be comfortable sharing this information, so be sure to have an honest reason to give them when you ask.

Look At Past Conversation History

If you've been in contact with this person for a while, you may be able to find out their birthday by looking through old text/email/social conversations. If the person has mentioned their birthday before, you might be able to find it scrolling through your old messages.

Get A Glimpse Of Their ID

We need to start by saying it is not ethical to go and take someone's ID, but there are ethical ways to go about getting someone to show you their ID. Get creative and ask to compare driver's license photos or compare ID formats if you're from different states. If you can get the person to show you their ID willingly, you'll get the chance to see their birthday listed right on their ID.

Scroll Through Old Photos

If you've been friends with this person for a while, you may have old photos that may indicate when the person's birthday is. Scroll through any old pictures that you may have and look for clues that might tell you when the person's birthday is.

View Their Birth Certificate

It is illegal and unethical to view someone's birth certificate without their consent. With that said, if the person is willing to show you this information, it has the exact information you're looking for.

How Accurate Are Online People Search Results?

No people search service can guarantee 100% accuracy because of the nature of public records. Reports aggregate what's publicly recorded; always treat results as a starting point rather than a verified official record.
