The fastest way depends on what you already know about them

Finding someone's birthday online usually means starting with the platforms where they've already shared it. Facebook shows birthdays on profiles if the person set their privacy to allow it — search their name, click their profile, and look for the birthday in the "About" section or on their timeline if they've posted about it. LinkedIn shows birthdays only to people in your network, and only if the person chose to display it. Google search with their full name plus "birthday" sometimes surfaces public records, news articles, or social media posts, though results depend heavily on how common their name is.

If you know them personally but don't have their birthday, the direct approach is fastest: text or call and ask. If you need it for a specific reason — sending a card, planning a surprise — most people are happy to tell you. If you're trying to find a birthday for someone you don't know well, the method changes based on your relationship and what information you already have.

Key Takeaways

  • Facebook and LinkedIn are the quickest sources if the person has a public or semi-public profile where they've shared their birthday.
  • Google search works best for public figures, people with unusual names, or anyone whose birthday has been published online.
  • Public records sites like Whitepages or Spokeo charge money and may show birthdays, but accuracy varies and the person may have opted out.
  • If you know the person, asking directly is faster and more reliable than searching.
  • Privacy settings matter — many people hide their birthday from everyone except close friends, making it unfindable online.

Searching social media profiles

Facebook is the easiest starting point because many people make their birthday visible. Go to the person's profile and look at the "About" section — if they've filled it in and allowed birthdays to show, you'll see the month and day. Some people post birthday wishes on their timeline, which also reveals the date. If their profile is private and you're not friends, you won't see this information.

LinkedIn shows birthdays only to your connections, and only if they've enabled it in their privacy settings. Instagram and Twitter rarely display birthdays on profiles, though people sometimes mention them in posts or bios. TikTok doesn't show birthdays publicly. If the person has a public Instagram account and you search their posts for "birthday" or look at their captions during their birth month, you might find it mentioned in a photo caption or comment.

Using Google and search engines

A Google search for someone's full name in quotes, followed by "birthday," works well if the person is a public figure, has a Wikipedia page, or has been mentioned in news articles. For example, searching "John Smith" birthday might return results if that John Smith is a musician, athlete, or public official. The search is less useful for common names — searching "John Smith" birthday returns thousands of results for different people.

You can narrow results by adding context: search their name plus their city, their profession, or a school they attended. If they have a personal website, blog, or professional bio online, Google may surface that. Some people list their birthday on alumni pages, professional directories, or community websites. The more specific information you include in the search, the more likely you'll find the right person.

Public records and people-search websites

Sites like Whitepages, Spokeo, BeenVerified, and TruthFinder compile public records and sometimes display birthdays. These sites charge money for detailed reports — usually between $10 and $30 for a single search. Accuracy varies because the data comes from public records that may be outdated or contain errors. Many people have also opted out of these sites, so the birthday may not appear even if the person exists in public records.

Public records themselves — like voter registration, property records, or court documents — sometimes include birthdays, but accessing them usually requires visiting a government office or using a specialized records search service. This approach is slower and more expensive than social media, so it's mainly useful if other methods fail or if you need to verify information you've already found.

What to do if you can't find it online

If someone's birthday isn't on social media or public records, they've likely chosen to keep it private. This is common — many people restrict birthday visibility to close friends only, or don't post it online at all. In this case, the only reliable way to get the information is to ask them directly or ask a mutual friend who might know.

If you're trying to find a birthday for a professional reason — verifying someone's identity, confirming information for a background check, or similar — explain why you need it. Most people will share their birthday if they understand the purpose. If you're planning a surprise and don't want to ask directly, a mutual friend is usually your best option.

Privacy and what you should know before searching

Searching for someone's birthday online is generally fine if you're doing it for a legitimate reason — sending a card, planning a party, or satisfying curiosity about someone you know. However, using someone's birthday to access their accounts, impersonate them, or commit identity theft is illegal. Birthdays are often part of security questions or two-factor authentication, so treat them as sensitive information.

If someone has chosen not to share their birthday publicly, respect that choice. Many people hide this information specifically to protect their privacy and security. If you find a birthday online but aren't sure it's accurate, verify it with the person before using it for anything important.

Frequently Asked Questions

Can I find someone's birthday if their Facebook profile is private?

Not unless you're friends with them. Private profiles hide the birthday section from non-friends. If you're not connected, you'd need to ask them directly or find the information through another source like a public records site or mutual friend.

Do people-search websites always have accurate birthdays?

No. These sites pull from public records that may be outdated, incomplete, or contain errors. Many people have also removed themselves from these databases. Always verify a birthday you find this way by asking the person or checking another source.

Is it legal to search for someone's birthday online?

Yes, searching public information is legal. Using that information to impersonate someone, access their accounts, or commit fraud is not. Treat birthdays as sensitive information even though they're often publicly available.

What if I only know someone's first name and city?

Google search becomes much harder with limited information. Try searching their name plus the city, school, or workplace if you know it. If they have social media, searching their name on Facebook or LinkedIn directly might work better than a general Google search.

Can I find a birthday from an old email address or username?

Sometimes. If that email or username is linked to a public profile, you might find birthday information there. Search the email address or username in Google, or try searching it on social media platforms. Results depend on whether the person used that identifier publicly.
