Jordan Ellis Private Investigator Austin, TX | (555) 123-4567 | jordan.ellis@email.com Dear Renata Aslanian, I'm writing to apply for the Private Investigator position at Ashford Investigative Services. Clients hire a private investigator for answers that hold up, and gathering evidence thoroughly and within legal boundaries has been my focus over five years as a licensed investigator. In my current role I conduct surveillance, background investigations, and insurance fraud investigations, and I built a case that provided documented evidence leading to a favorable resolution for a client in a contested insurance claim. I'm licensed as a private investigator, conduct research using public records and legal databases, and I document findings meticulously so evidence holds up if a case proceeds to legal action. I'd welcome the opportunity to bring that same thoroughness to Ashford Investigative Services. Thank you for considering my application. Sincerely, Jordan Ellis
How to write a private investigator cover letter
Hiring managers screen security and protective service candidates for judgment under pressure first — a strong private investigator cover letter proves that, then show an agency you can gather evidence thoroughly and legally to give clients the answers they need.
Your resume lists your certifications and assignments; the letter's job is to show the judgment behind them — a specific incident you handled well, in your own words.
Follow these steps to write yours.
1. Lead with your certification and one incident result
State your certification or licensure clearly near the top, then open with one concrete example of an incident you prevented or de-escalated — not a general claim about being vigilant or reliable.
2. Show you stay calm and follow procedure under pressure
Reference a specific example of following protocol correctly during a high-stakes or ambiguous situation. This signals the composure hiring managers screen for beyond a clean background check.
3. Close with your certifications and availability
Restate your certification or licensure status, note your shift availability if relevant, and invite a conversation. Keep the sign-off direct and professional.

ATS tips
- Use the exact certification and training terms from the private investigator posting (e.g., "POST certified," "CPR/AED") rather than paraphrasing them.
- Spell out acronyms at least once so both parsers and non-specialist HR staff can follow.
- List certifications and training as plain text — avoid icons or graphical skill ratings.
- State licenses and certifications by their exact, official title.
Common mistakes to avoid
- Claiming to be vigilant or reliable without a specific incident that proves it.
- Burying your certification or licensure status instead of stating it clearly near the top.
- Describing duties instead of a specific, measurable private investigator result.
- Disclosing identifiable incident, victim, or case details — describe situations generally to protect confidentiality.
- Sending an identical letter to every posting instead of matching it to the facility type and risk level involved.
Frequently asked questions
Should a private investigator cover letter mention licensure?
Yes, clearly. State private investigator licensure is typically a hard requirement and should be stated directly near the top of the letter.
Should I mention a specific case outcome?
Yes, in general terms — describing a case where your evidence led to a favorable resolution, without disclosing client or case-identifying details, is strong evidence of investigative skill.
How do I show my documentation holds up legally?
Reference your approach to meticulous, legally compliant documentation, since evidence that doesn't hold up in court or arbitration has little value to a client.
What if I'm moving from law enforcement or insurance investigation into PI work?
Lead with your relevant investigative background, and note your private investigator license status or the process you're pursuing to obtain one.
