Best reference check software in 2026: automated and AI tools

As of November 2026, the best reference check software depends on who you hire and how you want references to answer. Crosschq 360 is the strongest fit for US mid-size and enterprise teams that want fraud signals on every reference; Xref suits smaller employers that want a published monthly price and AI reference summaries; Referoo suits agencies in Australia, New Zealand and the UK that need email, SMS and phone references; and Checkster, now Harver's reference checking, suits high-volume employers. HiPeople fits teams that want references next to assessments, while Zinc and Certn sell references as part of a wider pre-employment check, with Certn also offering phone references made by its own team.

Everything about each product below comes from the vendor's own site, linked and dated November 2026. If you need the questions rather than software, start with our reference check template.

How we chose

• It must collect references itself: send requests, gather answers by survey, SMS or phone, and return a report. Tools that only store notes were left out.
• It must say how references are checked: we looked for the vendor's own description of verification and fake-reference detection, and quote it as the vendor puts it.
• It must be sold today under that name: where a product now belongs to another company, we say so only when the vendor's site says it.
• Buyers covered: agency recruiters, in-house teams from small business to enterprise, and high-volume hourly hiring.
• Sources: vendor websites and help centers, checked in November 2026. No ratings, review counts or vendor statistics.

Which reference check tools are worth a look?

Crosschq 360

Crosschq sells 360 Reference Checks as one module of a hiring platform that also includes AI interviews, assessments, fraud detection and ID verification through ID.me (Crosschq). References answer online surveys, with "135+ role-specific survey templates" and custom questions (360 page), and the candidate completes a self-reference survey as well (candidate help). Its help center is the most detailed on fraud of any vendor here: each check gets a Low, Medium or High Fraud Risk rating built from alerts such as "Two or more surveys completed on the same device," mismatched LinkedIn work histories, shared IP addresses and disposable email domains or VoIP numbers. Crosschq says the alerts prompt review and do not make hiring decisions (fraud risk). AI summaries of 360 reports, announced in March 2025, are switched on in report settings (Crosschq). Limits: no phone references, and pricing is not published; you book a demo. Best for: US mid-size and enterprise teams on a major ATS that want fraud signals on every reference.

Xref

Xref sends online reference surveys that references complete on a phone or computer, lets you send requests to up to 100 candidates at once, and supports several languages (Xref). On fraud, Xref says its algorithm "monitors multiple data touchpoints throughout the referencing process" and alerts you to unusual activity; its price list includes "Report analytics, sentiment & fraud detection" on every plan. The homepage introduces AI Reference Summaries, an overview of strengths, areas to improve and key points from all of a candidate's references (Xref). Xref is the only vendor here with full published plans, priced by company size with a yearly cap on unique people checked: Starter (1–74 employees, 25 people) $70 a month on annual billing or $80 paid monthly; Growth (76–150, 50 people) $140 or $160; Plus (151–300, 100 people) $290 or $335, adding custom questions; Premium (301–500, 200 people) $485 or $560, adding integrations support; Enterprise by quote. Prices are also shown in Australian and New Zealand dollars (Xref pricing). Limits: no phone option described, and the price list adds custom questions only from Plus up. Best for: small and midsize employers that want a known monthly cost.

Referoo

Referoo lets references answer by email questionnaire, by SMS (which it suggests for non-desk roles), or by phone, where the recruiter records a verbal reference against a template. Its built-in fraud detection flags duplicate IP addresses across referee responses and suspicious response patterns; the free trial lists "LinkedIn verification of referees" and IP tracking, and referee ID verification is optional. Two plans are named, Essential and Hub, with Hub adding ID and right-to-work checks and "Enhanced fraud detection"; prices are not published, and there is a 14-day trial (Referoo, trial). The site is built around Australia, New Zealand and the UK, with UK DBS and Australian criminal history checks alongside references (Referoo). No AI features are described. Best for: recruitment agencies in those markets on JobAdder, Bullhorn or Vincere.

Checkster, now Harver Reference Checking

checkster.com now redirects to Harver, which presents the product as "Checkster, Harver's Reference Checking Solution"; the same page carries a banner saying Outmatch is now part of Harver, so Outmatch's and Checkster's reference checking are one product today. The recruiter adds the candidate's contact details, the candidate enters references (typically three to five, the page says), and each reference answers a survey designed to take about two minutes on a phone. On fraud, "Harver's proprietary algorithm determines the legitimacy of each reference," aimed at family members posing as former managers and candidates completing their own checks. References can also opt in to hear about jobs with you, which Harver pitches as a sourcing channel (Harver). The page says it "integrates with most ATS"; Harver's integrations page names iCIMS Prime, UKG and Workday (integrations). Pricing is not published. Best for: high-volume employers, especially those already using Harver.

HiPeople

HiPeople sells reference checks next to application screening, assessments, AI interviews and interview notes, and says its agents handle "outreach, scheduling, rescheduling and follow-ups." References get a request to confirm a previous working relationship and tap Confirm, Adjust or Can't confirm against the candidate's employer, role and dates. For verification it cites "professional network authentication, shared experience verification and explicit job titles"; for fraud it fingerprints everyone involved, tracks IP activity, checks phone number age, provider and country, and flags VPN use or unexpected locations. When answers are "unclear or contradictory," its agents ask follow-up questions, and a bias detection feature flags overly positive, negative or inconsistent references (HiPeople). Its help center says a shared office network can cause an innocent fingerprint match (HiPeople docs). Integrations listed include Greenhouse, Workday, SAP SuccessFactors, Lever, Ashby, Bullhorn and Teamtailor (integrations). Pricing is not published. Best for: teams that want references, assessments and screening from one vendor.

Zinc

Zinc is a pre-employment checks platform: references sit beside criminal, right-to-work, financial and employment checks. References answer a "secure, custom branded digital questionnaire," Zinc chases them up to five times, and it "flags mismatched dates, job titles, and any unclear information for further review." For UK candidates it also offers HMRC employment checks using the candidate's Government Gateway login (Zinc references). No AI is described for references. Plans are Pay as you grow, SMB and Enterprise, with no prices published (Zinc); Greenhouse, Workday, iCIMS, SmartRecruiters, Lever, Ashby and Teamtailor appear on its integrations page. Best for: UK teams that want references in the same flow as their other checks.

Certn

Certn is a background screening company that offers two kinds of reference check: a digital one, where references complete a customizable online questionnaire, and a phone one, where "references are interviewed by Certn's verifications team." The candidate supplies one to three references (Certn). The page does not describe how references are verified or screened for fraud. Certn's US self-serve price list shows Reference Checks at $29.99 per check, by phone, email or SMS (US pricing); the Canadian list shows CA$39.99 (Canada pricing), while the product page says "Starting at $4.99," so confirm the figure for your package. Best for: employers who want a third party to make reference calls and bundle them with background checks.

What we left out, and why

SkillSurvey: iCIMS announced it had acquired SkillSurvey in October 2022 (iCIMS). As of November 2026, skillsurvey.com redirects to an iCIMS page that offers existing customers a login and no product details, so we could not confirm it is sold to new buyers; iCIMS customers should ask their account team. Hireproof: its site describes a structured interview platform and does not offer reference checks.

Automated reference surveys vs reference calls: which fits?

• Agency placements: surveys keep temp and contract desks moving, and Referoo adds SMS and a phone template for references who will not fill in a form. For permanent placements, survey first and call the former manager, because the client expects a write-up in your words.
• Executive search: call. Senior references expect a conversation, the useful answers come from follow-ups, and a survey link can feel careless at that level. Use our reference call script, and get the candidate's consent before any reference they did not name.
• Hourly roles: surveys that work on a phone in a few minutes, such as Checkster's, fit shift managers who will never return a voicemail. Pair them with the rest of a fast process; our guide to AI tools for high-volume hiring covers the steps around it.

For reference calls you run yourself, a note taker can transcribe the call once the reference agrees, including desktop apps such as Interview Signal that capture the call on your computer without a bot; our guide to AI note takers on reference check calls covers consent and what to keep. We make Interview Signal; everything about the other products on this page comes from their own sites, linked and dated.

What may you ask a reference, and what may you not?

Ask about the job: dates, title, scope, results, how the person worked with others, and whether the reference would rehire them. The reference check template has 14 questions with what to listen for. The legal limits come from the same laws that govern interviews:

• Job-related questions only. The EEOC says pre-employment questions should, as a general rule, be limited to what is essential to decide whether a person is qualified, and that employers are "explicitly prohibited from making pre-offer inquiries about disability" (EEOC).
• No back door through the reference. The EEOC's 1995 ADA guidance on pre-employment questions, still on its site, says an employer may not ask third parties, including former employers, "any questions that it could not directly ask the applicant" (EEOC guidance). Check that your vendor's question templates follow the same rule.
• What former employers may say is set by state law. Florida, for example, makes an employer immune from civil liability for disclosing information about a former employee to a prospective employer unless it was "knowingly false" or violated the employee's civil rights (Fla. Stat. 768.095). Other states differ; our page on employment reference laws covers the statutes state by state.

Do you need consent and candidate notice for reference checks?

Yes, in practice, and sometimes by law. Get the candidate's written permission to contact the references they name, and tell them which tool will contact those references. Tell references what their answers will be used for and who will see them. Then check the federal rules that apply when a third party is involved:

• FCRA when a third party compiles the report. A report from a consumer reporting agency for employment purposes is a consumer report, and one in which information on character or reputation "is obtained through personal interviews" with people who know the candidate is an investigative consumer report (15 U.S.C. 1681a). A report "solely as to transactions or experiences between the consumer and the person making the report," such as a former employer describing its own experience, is excluded.
• Notice and permission. The FTC says employers using consumer reports must give the candidate written notice "in a stand-alone format" and get written permission, and for investigative reports must give written notice that one may be requested (FTC). The statute requires that notice "not later than three days after the date on which the report was first requested" (15 U.S.C. 1681d), and adverse action notices follow if the report contributes to a no. Our FCRA background check guide walks through the steps. A screening company that phones references for you is a different case from survey software you run yourself, so ask each vendor how it treats its reports.
• AI scoring. If a tool uses machine learning, statistics or AI to turn reference answers into a score or classification that "substantially assists or replaces discretionary decision-making" for a New York City job, Local Law 144 may treat it as an automated employment decision tool, which needs a bias audit within the past year and notice to candidates 10 business days before use (DCWP FAQ, DCWP). See our Local Law 144 guide, and for the federal side, Title VII disparate impact.

This is general information as of November 2026, not legal advice.

What should AI do in a reference check, and what should it not?

• Summaries save reading, not judgment. AI summaries from Crosschq and Xref condense many answers into one view, but a summary can turn "I'd rehire her for the right role" into "would rehire." Read the hedged answers yourself.
• Fraud flags start a check. A shared office network can cause an innocent match, as Crosschq and HiPeople both note. Phone the reference through their employer before you act; our guide to spotting fake references has the steps.
• A person decides. Treat a reference score as one input next to the interviews, and record why you advanced or declined someone.
• Keep it accessible. Offer a phone option for references who cannot use a form, and adjust deadlines for candidates who ask for an accommodation.

Reference check software setup checklist

1. Decide the method per role family: survey, call, or survey then call.
2. Write or pick job-related questions, and remove anything you could not ask the candidate directly.
3. Set the number and type of references, including at least one former manager.
4. Add candidate authorization wording; if a screening company is involved, add its FCRA disclosure and authorization.
5. Write the note references see: purpose, who reads their answers, how long you keep them.
6. Turn on the vendor's fraud signals and agree who follows up a flag, and how.
7. Test the ATS integration with one requisition and check where the report lands.
8. If AI summaries or scores are on, check them against the raw answers for the first 20 checks.
9. Set retention for reference reports in line with your other hiring records.
