How to Do a Background Check on Someone You're Dating
In this guide
You want to know who you're actually meeting before you show up. A background check on someone you're dating isn't about being paranoid, it's about confirming that the person matches what they've told you, before you invest more time, trust, or money.
Done properly, this takes under an hour and uses only public information. Done sloppily, you end up with the wrong person's record, or a false sense of security because you missed the gaps every public search has.
This guide walks through exactly what to gather first, where to look for free, when a paid service earns its cost, and how to read what you find without over- or under-reacting to it.
What you need before you start
A background check is only as good as the identifiers behind it. Common first names produce dozens of false matches, so gather as much as you comfortably can before searching anything.
- Get their full legal name, including a middle name or initial if you can find one naturally in conversation.
- Note their approximate age or, better, their date of birth if it has come up.
- Confirm the city and state where they currently live, and any past cities they've mentioned.
- Save a clear photo from their profile or a recent selfie they've sent you.
- Write down their phone number or email if you have it, since both can be searched independently.
Free public sources to check first
County and state court portals
Most US counties publish civil and criminal case records through a searchable court portal. Search by full name and county of residence, and expect some noise: many portals return everyone who shares that name statewide.
State case search and sex offender registries
Every state runs its own criminal case search, and the National Sex Offender Public Website lets you search across all state registries by name or by address radius in one pass. Our guide on sex offender registry checks covers how to search this correctly and what tiers actually mean.
Property, licensing, and life-event records
- County assessor sites show property ownership, which can confirm an address and sometimes a co-owner's name.
- State licensing boards let you verify a claimed profession, from nursing to real estate to law.
- Obituary archives can surface family names and past addresses that help you confirm identity.
- Marriage and divorce indexes, where public, can tell you whether someone has an undisclosed spouse.
- Local news archives sometimes surface arrests, lawsuits, or business disputes that don't appear in a basic court search.
Paid aggregators and their limits
Paid people-search sites pull from the same public records but compile them into one report, which saves time. Their weakness is data age: aggregators often lag court systems by weeks or months, so a very recent filing, a recent move, or a just-dismissed charge may not show up yet or may show up as still active.
Treat any paid report as a starting point, not a conclusion, and cross-check anything alarming against the original court record before you act on it.
Confirming you have the right person
The single biggest failure mode in a personal background check is matching a record to the wrong John Smith. Before you treat any hit as real, confirm at least two of the following line up: middle name, date of birth, current or past address, or a distinctive employer.
- Cross-reference the address on a court record against an address they've mentioned or that appears in property records.
- Check the date of birth on a record against their stated age, allowing that people sometimes round down.
- Look for a middle name or suffix (Jr., II) that narrows a common surname to one person.
- If nothing matches beyond the first and last name, treat the record as unconfirmed, not as theirs.
How to read a criminal record entry
Court records use precise language that's easy to misread if you're not used to it. A charge is an accusation, not a finding of guilt. A conviction means a court found the person guilty or they pleaded guilty. Dismissed means the charge was dropped, sometimes for lack of evidence, sometimes as part of a plea deal on a different charge. Pending means it is still working through the court and nothing has been decided. Sealed or expunged records generally won't appear in a public search at all, which is a deliberate legal outcome, not a gap in your search.
Where public records fall short
No public search is complete. Records can be misfiled, delayed in reaching a statewide index, or simply never digitized for older cases. Someone who has moved states recently may have records still filed under a state you haven't searched. And, as covered in our guide to what a date background check can and can't tell you, a clean search result never proves someone is safe, it only means nothing surfaced in the sources you checked.
The FCRA line: what this is not for
This entire process is for personal safety judgment before a date, nothing more. Under the Fair Credit Reporting Act, any check used to decide employment, housing, credit, or tenancy must go through a certified consumer reporting agency with specific disclosure and dispute rights attached. Suss, county portals, and general people-search sites are not built or licensed for that purpose, and using them that way can expose you to legal liability.
Proportionality and ethics
There's a real difference between a reasonable pre-date check and ongoing surveillance. Checking public records once, before meeting someone new, is a normal safety step that millions of people take. Repeatedly searching someone after they've asked you to stop, tracking their location, or monitoring their social activity day to day crosses into behavior that can frighten or harm the other person and, in some jurisdictions, break the law.
- Do one check before meeting, not a running investigation throughout the relationship.
- Don't share what you find publicly or use it to confront someone aggressively.
- If a record raises a real safety concern, prioritize meeting in public and telling a friend your plans over digging deeper.
- Respect that everyone, including someone with a record, may have already served their consequences.
Quick-reference checklist
- Gather full name, approximate age, city/state, and a photo before you search anything.
- Start with free county and state court portals, plus the national sex offender registry.
- Check property, licensing, and obituary or marriage records for identity confirmation and undisclosed relationships.
- Use a paid aggregator only as a time-saver, and verify anything serious against the original record.
- Confirm at least two identifiers before trusting a match to a specific person.
- Never use this process for employment, housing, credit, or tenant screening.

Frequently asked questions
- Is it legal to run a background check on someone I'm dating?
- Yes, searching public records like court filings, property records, and sex offender registries for personal safety purposes is legal in the US. The line you must not cross is using the same information for employment, housing, credit, or tenant decisions, which requires an FCRA-compliant consumer reporting agency instead.
- How much does a personal background check cost?
- County and state court portals, the national sex offender registry, and property records are free to search yourself. Paid aggregators or a service like Suss typically charge a small subscription fee, ranging from a few dollars a week to under ten dollars a month, in exchange for compiling sources into one report.
- What if I can't find any record at all?
- No record found usually means exactly that, nothing surfaced in the sources searched. It does not guarantee a clean history, since sealed records, out-of-state cases, and recent filings can all be invisible to a public search. Combine it with other safety steps rather than treating it as proof.
- Can I check someone using just their first name?
- You can, but expect a high false-positive rate. A first and last name alone often matches many unrelated people, especially with common names. Confirming a date of birth, middle name, or address dramatically improves accuracy.
- What's the difference between an arrest and a conviction?
- An arrest means police took someone into custody on suspicion of a crime; it is not evidence of guilt. A conviction means a court found the person guilty, either through trial or a guilty plea. Focus your safety judgment on convictions, and treat unresolved arrests with more caution about drawing conclusions.
- Should I tell someone I background-checked them?
- There's no legal requirement to disclose it, and many people choose not to since it's a routine safety step. If something you find genuinely concerns you, it's usually better to be cautious about meeting rather than confronting them with the search results directly.
