Applicant Tracking Systems (ATS) are software tools employers use to scan resumes for fit. They look for keywords, section titles, and simple formatting. If your resume lacks key words or uses odd layout, an ATS can skip it.

For a Postal Service Window Clerk you need to show skills the system will search for. Include customer service, cash handling, money orders, POS terminals, shipping, tracking, ZIP code verification, ID verification, and USPS forms. Mention any certifications like state ID training or cash-handling courses.

Use clear section titles. Keep these exact headings:

• Work Experience
• Education
• Skills

Avoid complex formatting. Do not use tables, columns, text boxes, headers, footers, images, or charts. ATS often misread those elements and drop content.

Stick to readable fonts like Arial, Calibri, or Times New Roman. Use standard file types such as .docx or PDF. If you use PDF, make sure text extracts cleanly and the file is not a scanned image.

When you write bullets, use short action lines. Start with a verb and add measurable results if you can. For example, show how many transactions you processed, or how you reduced customer wait time.

Common mistakes to avoid:

• Replacing exact keywords with creative synonyms that ATS won't match.
• Putting critical info in headers or footers that ATS ignores.
• Leaving out tools and forms like USPS documentation, tracking systems, or POS names.

Follow these steps and you improve your odds of passing an ATS and getting your resume read by a hiring manager.

Pick a clean template with a reverse-chronological layout. Use a single column so an ATS and a hiring manager can read your experience fast.

Keep length to one page if you have under 10 years of relevant postal or customer service work. If you have long management or operations history, two pages can work, but cut anything that doesn't show direct postal tasks.

Use simple, ATS-friendly fonts like Calibri or Arial. Set body text to 10–12pt and headers to 14–16pt. Keep line spacing at about 1.0–1.15 and leave clear margins for white space.

Use bold and italics sparingly for headings and key achievements. Avoid graphics, text boxes, or complex columns that break parsing. Use standard headings like Contact, Summary, Experience, Skills, and Education.

Avoid common mistakes like odd fonts, tiny margins, and long paragraphs. Don’t cram every job duty on one line. Cut filler and list measurable results, such as parcels handled per shift or error rate improvements.

Order each job entry with employer, location, dates, job title, and 3–6 bullet points. Start bullets with action verbs. Tailor a Skills section for things like cash handling, PO systems, ID verification, and customer service.
