Most candidates think the biggest background check risk is a criminal record or a fake degree. It is not. The most common thing that stalls an offer in the final stretch is a date mismatch on employment history. Specifically, a one-month gap between what the resume says and what HireRight comes back with.
This happens constantly. And it is almost never fraud.
Here is what is happening on the recruiter's side of your background check right now, and exactly what you need to do about it.
In Short: A one-month date discrepancy on a HireRight background check is one of the most common findings in tech hiring. It usually comes from payroll processing lag, start date rounding, or a staffing agency mismatch. Not intentional misrepresentation. On the recruiter's dashboard, it flags as a "Discrepancy" or "Decisional" status, not a fail. A W-2 from that tax year resolves it in most cases within 24 to 48 hours.
What is Actually Happening on Our End While You Wait
Here is what happens on the recruiter's side from the moment HireRight starts verifying your employment.
Step 1: HireRight Queries The Work Number First
Before anyone manually contacts your former employer, HireRight runs an automated check against The Work Number, the Equifax-owned database that stores payroll records for more than 2.7 million employers. If your former company uses ADP, Paychex, Workday Payroll, or a similar processor, their data feeds into The Work Number and HireRight pulls it instantly.
The Work Number returns three things: your official payroll title, your first and last payroll dates, and your employment status (active or terminated).
Notice what it returns: payroll dates. Not your physical start date. Not the date you signed your offer letter. Not the date you walked into the building for your first day. The date you first appeared in the payroll system.
If you started on the 27th of March but your company's next payroll cycle did not run until April 1st, The Work Number records your start as April. Your resume says March. HireRight flags a one-month discrepancy.
That is it. That is where most of these come from.
Step 2: Manual Outreach (If The Work Number Doesn't Have It)
If your former employer is too small to use The Work Number, or if their data is incomplete, HireRight falls back to direct outreach. A researcher calls or emails the former employer's HR department.
This is where delays happen. A small startup's HR function might be one person handling 12 other things. They might not respond for three to five business days. That silence shows up in your candidate file as "pending." Not failed. Not rejected. Pending.
If HireRight still cannot reach the employer after multiple attempts, the status shifts to "Unable to Verify." This is where candidates panic. It should not be a panic situation. I will explain what that status actually means for your offer in a moment.
Step 3: The Flag Appears on the Recruiter's Dashboard
Once HireRight has a discrepancy to report, it appears on the recruiter's ATS dashboard as one of three statuses:
"Discrepancy": HireRight verified your employment but the dates, title, or both do not match what you entered on the background check form. The employer has the verified data and your submitted data side by side.
"Decisional": Similar to Discrepancy, but used when HireRight has passed the finding to the hiring employer for review. The ball is in the employer's court.
"Unable to Verify": HireRight could not confirm the employment at all through automated or manual means. They are now typically asking you to submit documentation.
None of these are a rejection. Every one of them is a review prompt.
Here is what I actually do when I see one of these flags: I open the report, look at the specific field that triggered the flag, and compare the delta. A one-month date difference gets 15 seconds of my attention before I move it to the "minor, likely explainable" pile and flag it to the candidate for documentation. A discrepancy where a candidate claimed to work somewhere from 2019 to 2022 and the record shows 2021 to 2022 gets a different level of scrutiny.
The Five Reasons Dates Come Back Off By a Month (and Which One Is Yours)
Understanding why your date is off tells you exactly what document fixes it.
Reason 1: Payroll Processing Lag
You started work before the next payroll cycle. Your offer letter says January 15th. The payroll system did not pick you up until February 1st. The Work Number returns February. Your resume says January.
Fix: Your offer letter. It shows the January 15th start date on company letterhead. HireRight and the recruiter both accept this.
Reason 2: End-of-Month Rounding on the Resume
You left a job on March 28th. Your resume rounds to "March 2022." The Work Number returns a termination date of April 3rd (because your final paycheck processed in the next cycle). HireRight flags April vs. March.
Fix: Your final pay stub from that employer showing the pay period ending date. Alternatively, your W-2 from that tax year shows the annual wages which corroborate the timeline.
Reason 3: Staffing Agency vs. Client Company Mismatch
This one catches candidates completely off guard. You worked at Google through a staffing agency from January to December 2022. Your resume lists Google. HireRight contacts Google HR. Google has no record of you as an employee, because you were employed by the agency, not Google.
The Work Number or Google HR returns "unable to verify" or "no record found." HireRight flags it as a discrepancy against the role you listed.
Fix: Contact information for your staffing agency, or your W-2 from the agency (which will show the agency name as the employer, not Google). You may need to add a brief clarification to your recruiter explaining the contractor arrangement.
Reason 4: Memory Error on the Resume
You wrote your resume two years ago from memory, typed "June 2021" for your start date, and your actual payroll record shows July 2021. This is extremely common. People do not keep their employment records in front of them when writing resumes.
Fix: Your W-2 for that year, which confirms the wages earned and anchors the timeline without requiring a perfect date match.
Reason 5: Overlap From a Previous Role
You left Company A and started Company B with a week of overlap. You rounded Company A's end date forward to cover the gap cleanly on your resume. Company B's start date on the resume shows the same month as Company A's end date. HireRight, pulling both records, flags the apparent overlap.
Fix: Either document from either company confirming the actual dates. A brief explanation to the recruiter that you transitioned directly with a short overlap period is usually sufficient.
What "Unable to Verify" Actually Means (and When to Worry)
"Unable to Verify" does not mean HireRight found evidence that you did not work there. It means they could not complete the verification through their standard channels.
The most common causes have nothing to do with you:
- The former employer is out of business or was acquired and HR records were not transferred
- The HR contact is on leave or the department is understaffed
- The employer uses a verification policy that requires a written release form before they confirm anything
- The employer uses The Work Number but your records are incomplete in the database
When "Unable to Verify" appears on my dashboard, my first move is to reach out to the candidate and ask for proof of employment. I am not assuming fraud. I am following the standard documentation process to close out the check.
The documents that resolve "Unable to Verify", in order of how quickly they work:
- W-2 from that tax year (confirms employer, year, and wages; no exact date needed)
- Pay stub from that employer showing the pay period
- Offer letter from the employer showing start date
- A signed verification letter from a former manager on company letterhead
If the company is truly defunct and you have none of the above, a 1099 form, bank statements showing payroll deposits, or a LinkedIn recommendation from a manager at that company with the employment period noted can supplement your file.
What You Should Do Right Now (Based on Where You Are in the Process)
HireRight has not contacted you yet and your background check is in progress:
Pull your own records now. Find the W-2 for every employer you listed on the background check form. Make sure the employer name on your W-2 matches the name you submitted to HireRight. Contractors: check that you submitted the agency name, not the client name. Get everything organized so you can respond within 24 hours if HireRight reaches out.
HireRight sent you a task to provide documentation:
Log into the HireRight candidate portal and upload the documents directly there. Do not email the recruiter with attachments. HireRight needs the documentation in their system to update the report status. After uploading, send your recruiter a one-line note: "I have submitted documentation through the HireRight portal to resolve the date discrepancy. Please let me know if anything else is needed."
Your recruiter mentioned the flag:
Give them the short, factual explanation of what caused the mismatch. One of the five reasons listed above applies. Offer to send documentation. Do not apologize excessively or over-explain. A recruiter who already knows you, has already gone through the interview process with you, and has already extended an offer is motivated to close this. Make it easy for them to close it.
You received a pre-adverse action notice:
This means the employer is considering taking adverse action based on the background check findings. Under the FCRA, they must give you at least 5 business days to respond before making a final decision. File a dispute with HireRight through their candidate dispute process immediately. Provide your documentation. Then contact your recruiter, reference the dispute, and ask for a brief timeline extension.
The Documents That Fix This, Ranked by Reliability
| Document | What It Proves | How Fast It Works |
|---|---|---|
| W-2 (from that tax year) | Employer name, year, wages | Near-instant, highly trusted |
| Offer letter | Start date, employer, role | Same day if clear |
| Pay stub (showing pay period) | Exact date range | 24 to 48 hours |
| Signed letter from former manager | Custom verification | 24 to 72 hours |
| LinkedIn verification from manager | Supplemental only | Works as backup, not primary |
| Bank statements showing deposits | Employment tenure, not title | Last resort, slower |
The W-2 is the single most reliable document for resolving a HireRight employment date discrepancy. It is an IRS-issued tax document, it carries the highest credibility of any employment record, and it does not need to show an exact start date to confirm the timeline.
HireRight vs. Sterling: Does the Vendor Matter?
If you are wondering whether this process differs between HireRight and Sterling: yes, slightly.
HireRight is the background check vendor used by many large multinational companies including several FAANG-adjacent employers. Their candidate portal requires you to upload documents directly into their system. Sterling's Candidate Hub has a different interface but a similar document upload workflow.
The underlying verification process (querying The Work Number first, then manual outreach, then candidate documentation request) is essentially identical between the two. The FCRA rules apply equally to both.
What differs is response time. HireRight has drawn consistent criticism for slow turnaround on manual verifications and repetitive documentation requests. If HireRight asks for a document, submit it once through the portal, note the submission date, and follow up if the status has not changed after 5 business days.

FAQ: HireRight Employment Dates Off by a Month
Why are my employment dates off by a month on HireRight? The most common cause is payroll processing lag. Your physical start or end date and the date you appeared in your former employer's payroll system are often different by days to weeks. HireRight pulls payroll dates from The Work Number database, not your actual start date. A one-month difference between your resume and the payroll record is one of the most common background check findings in tech hiring.
Will a one-month date discrepancy on HireRight fail my background check? No. A one-month discrepancy typically shows up as a "Discrepancy" or "Decisional" status on the recruiter's dashboard, not a rejection. Recruiters assess the difference and determine whether it is material. A one-month gap is almost universally treated as a minor, explainable variance, not evidence of intentional misrepresentation.
What document do I need to fix a HireRight date discrepancy? A W-2 from the tax year in question is the fastest and most reliable fix. It confirms the employer name and wages without requiring a precise day-level date match. Offer letters and pay stubs showing the pay period are also accepted.
What does "Unable to Verify" mean on a HireRight background check? It means HireRight could not confirm your employment through The Work Number or direct employer outreach. It does not mean they found evidence you did not work there. Common causes include a defunct employer, an unresponsive HR department, or incomplete data in The Work Number. HireRight will contact you for documentation to resolve it.
What is "Decisional" status on HireRight? Decisional means HireRight has passed the background check findings to your prospective employer for review. The employer now makes the call on whether the finding is significant enough to affect the hiring decision. For date discrepancies, most employers clear decisional status once documentation is provided.
Can HireRight rescind a job offer? HireRight cannot rescind your offer. Only the employer can do that. HireRight is a reporting agency. The employer makes all adverse action decisions. Before rescinding any offer based on a background check finding, the employer must follow the FCRA pre-adverse action process, including sending you a copy of the report and giving you at least 5 business days to respond.
My former company went out of business. How do I verify employment with HireRight? If your former employer is defunct, provide HireRight with a W-2 or 1099 from that tax year, pay stubs showing the employer name and pay period, or an offer letter from that employer. If you have none of these, bank statements showing regular payroll deposits can support your claim. Contact your recruiter proactively and explain the situation before HireRight completes their outreach.
Should I tell my recruiter about the date discrepancy before HireRight flags it? If you already know your resume dates differ from your official payroll records, tell your recruiter before the flag surfaces. One factual sentence covers it: "My payroll start date at [Company] may show as [Month] due to processing timing, while my offer letter shows [Month]. Happy to provide documentation to confirm." Being proactive eliminates the integrity concern before it forms.
How long does HireRight take to resolve a date discrepancy? Once you submit documentation through the HireRight portal, most date discrepancies resolve within 24 to 48 hours. Manual employer outreach takes longer, typically 3 to 7 business days depending on employer responsiveness. If the employer is unresponsive, HireRight typically shifts to candidate documentation within 5 to 10 business days.
Is a staffing agency employment verified under the client company or the agency? Under the agency. If you were a contractor placed at Google through a staffing agency, HireRight verifies the employment against the agency, not Google. If you listed Google on your background check form instead of the agency name, this will trigger an "Unable to Verify" status at Google and a discrepancy against the role you submitted. Correct this immediately by resubmitting with the staffing agency name and providing agency documentation.
