How to remove your date of birth from the internet

Date of birth is the quiet one. It rarely feels sensitive — people post it on social media every year — but it is one of the three or four fields that turn a name into a verifiable identity, and it is the field most commonly used to confirm you are you. Unlike a password it never changes, and unlike an address it never becomes out of date.

What you need to know first

Where your date of birth appears in a genuine public record — a court filing, a property deed, some voter rolls — it usually cannot be removed, because the record itself is public by law and the publisher is entitled to reproduce it. You can remove the copies held by commercial aggregators, which is most of what shows up in a search for your name, but the underlying public record stays. And because a date of birth never changes, any copy that leaked once remains accurate forever, which is exactly what makes it valuable to whoever holds it.

Where your date of birth comes from

• Voter registration records, which are public in many states and often include full date of birth
• Court and property filings that list parties by name and date of birth
• Marketing databases built from purchases, warranty cards and loyalty programmes
• Social media, where birthday fields are frequently public by default
• Breaches of any service that required your date of birth at signup

Name plus date of birth plus address is the standard triple used to verify identity over the phone and to match records between databases. It is what lets a stranger pass a knowledge-based security check, and it is what lets brokers confidently merge scattered records into one profile of you.

How to remove it, step by step

1. Opt out of the people-search sites carrying it. Most listings that show your age or full date of birth come from a handful of large aggregators. Their opt-outs are free and we publish step-by-step instructions for the ones that matter most.
2. Lock down social profiles. Set birthday visibility to private everywhere, or remove the year. Many platforms treat the year as optional. This also stops the annual public reminder that tells anyone watching exactly when it is.
3. Check your voter registration exposure. Several states publish voter rolls including date of birth, and some make them freely downloadable. Rules on confidentiality vary; your county elections office can tell you what is published and whether any exemption applies to you.
4. Stop giving it away unnecessarily. Plenty of services ask for a full date of birth when they only need to know you are over eighteen. Where a site accepts a partial date or an age range, use it — every place that does not hold it is one that cannot leak it.
5. Ask the big three data brokers to suppress it. The large background-data companies accept suppression requests that cover the underlying record rather than a single listing, which is more durable than opting out of consumer-facing sites one at a time.
