An alias search finds every name a candidate has been associated with, including maiden names, former married names, legal name changes, nicknames, and name variations, and searches criminal records under each one. Court records are filed under the name a person used at the time, and they don't update when that name changes. Without an alias search, a background check only finds records under the name on the application.
What Is an Alias in a Background Check?
In background screening, an alias is any name other than a candidate's current legal name that appears in public records, court systems, or other data sources. Common aliases include:
- Maiden names: a surname used before marriage
- Former married names: a surname taken at marriage and later changed after a divorce
- Legal name changes: names changed through a court order for any reason
- Hyphenated names: a candidate named Ana Torres-Reed may have records under "Ana Torres," "Ana Reed," or the full hyphenated name
- Middle names used as first names: someone who goes by their middle name professionally, while their legal first name appears in official records
- Nicknames: a candidate known as "Liz" may have records filed under "Elizabeth"
- Name variations and clerical errors: records filed under a misspelled version of a name
Most aliases have nothing to do with hiding anything. They're an ordinary result of marriage, divorce, and imprecise record-keeping. But from a screening perspective, each one is a place a record can be missed.
How an Alias Search Works
Step 1: The Address History Trace Identifies Names and Locations
An alias search starts with an address history trace. It uses the identifying information the candidate provides to pull their residential history and every name associated with them in public records and other data sources. It also confirms the candidate's identity and flags inconsistencies.
Step 2: Every Name Is Searched Where the Candidate Has Lived
The addresses show which counties need a criminal search, and the aliases show which names to search in each one. Court records are indexed by name and date of birth, and many counties require an exact name match. A search for "Michael" won't return a record filed under "Mike," and a search for a married name won't return a record filed under a maiden name.
Step 3: Potential Matches Are Verified
When an alias search returns a possible record, it's checked against the candidate's identifiers, such as date of birth, to confirm it belongs to the right person before it appears on the report.
An alias search is only as effective as the county searches that follow it. See what's in a background check report for how county searches fit with the rest of the check.
Examples of Records an Alias Search Catches
- The name change after marriage. A candidate changed their surname at marriage 5 years ago. A record from 7 years ago is filed under their maiden name. A search under the married name returns nothing. A search that includes the maiden name finds it.
- The divorce and name change back. A candidate used a married name for 10 years, then returned to their birth name. Records from those 10 years are filed under the married name.
- The middle name used professionally. A candidate legally named James Robert Smith has always gone by "Robert Smith." A record filed under "James Smith" may be missed in counties that require a close name match.
- The nickname on the application. A candidate lists "Liz." The court record is filed under "Elizabeth."
- The professional license under a prior name. A nurse's disciplinary history is attached to the license issued under her maiden name. A check of her current name shows a clean record. A search under her maiden name reveals the disciplinary action.
Benefits of Alias Searches
- More complete results. Records under prior names are included instead of silently missed.
- Stronger due diligence. For roles in healthcare, education, and finance, searching every known name is part of a defensible screening program.
- Fewer false matches. The same identifying information that finds aliases also helps confirm that a record belongs to the candidate.
- Consistency. Every candidate is searched under every associated name, not just the one they chose to list.
Challenges and Limits of Alias Searches
What Alias Searches Don't Do
An alias search is a tool for completeness. It isn't:
- A way to find records under names the candidate has never used
- A substitute for county-level criminal searches in the right jurisdictions
- A guarantee of completeness in counties with poor record digitization
- A way to access sealed or expunged records
Common Names Can Return the Wrong Person
A common name, especially a common maiden name, can return records belonging to other people. Every potential match needs to be verified before it's reported or used.
FCRA Rules Still Apply
Alias search results are part of the background check report, so the FCRA applies in full. Reporting limits apply under every name: an arrest that didn't lead to a conviction can't be reported after 7 years, whatever name it's filed under. If an alias search surfaces a record you're considering acting on, follow the pre-adverse and adverse action process.
How Bchex Handles Alias Searches
Bchex screening packages can include alias identification built directly into the screening workflow. The address history trace runs at the start of the order, and every associated name automatically feeds into the criminal searches in every relevant jurisdiction. When a potential match appears, Bchex verifies the match against the candidate's identifiers before it appears on the report, protecting against false positives from common names.
Bchex is PBSA-accredited, meaning its data sourcing, accuracy standards, and identity-matching practices have been independently audited.
Conclusion
A background check is only as complete as the names it searches. Court records stay filed under the name a person used at the time, so an alias search is what closes the gap between the name on the application and every name in the record. For employers who need thorough, defensible screening, alias coverage isn't an add-on. It's the difference between a full picture and a partial one.

FAQ
Is a Maiden Name an Alias?
Yes. In a background check, a maiden name is treated as an alias because records from before a name change stay filed under it.
What Does "Have You Ever Used an Alias" Mean on a Job Application?
It's asking for any other name you've used, including maiden names, former married names, legal name changes, and commonly used nicknames. It doesn't imply wrongdoing.
Is a Nickname an Alias?
It can be. If a nickname appears in records or you've used it on official documents, list it. Background checks may search common variations either way.
Does a Background Check Automatically Search for Aliases?
Not always. It depends on the provider and package. Ask whether an address history trace and alias searches are included.
Will a Maiden Name Show Up on a Background Check?
Usually, if the check includes an address history trace. Records filed under the maiden name are then included in the results.
Can Someone Hide a Criminal Record by Changing Their Name?
Generally no. A name change doesn't seal or expunge a record, and an alias search will find the prior name and search it.
What If an Alias Search Returns a Record That Isn't the Candidate's?
It should be caught before it's reported. Every potential match should be verified against the candidate's identifiers. Candidates can run a background check on themselves to catch errors early, and dispute them under the FCRA.
Should Candidates Disclose Their Aliases?
Yes. Listing prior names speeds up the check, and most will be found anyway. Leaving one off can look like an attempt to hide something.
