A quick definition: ATS means applicant tracking system, the software many employers use to collect and organize applications.
TL;DR
- 01Use a simple filename a person can recognize quickly. Blacklight's default pattern is
FirstName-LastName-Resume. If you keep multiple versions, add one practical label such as a role, company, or year for your own organization. This guide stays within broad resume-formatting guidance and does not make vendor-specific ATS claims.
What the approved source safely supports
CareerOneStop's resume formatting guidance focuses on readable structure, standard headings, and broad formatting compatibility.
Blacklight applies that same clarity-first approach to the filename: keep it plain and easy to identify.
A clean naming pattern
Blacklight recommendation:
FirstName-LastName-Resume
If you need separate versions, one label is usually enough:
FirstName-LastName-ProductManager-ResumeFirstName-LastName-Acme-ResumeFirstName-LastName-Resume-2026
Use one separator style.
Make sure the filename matches the version inside the file.
Quick do / do not checklist
Do:
- add a role label when you keep different resumes for different job families
- add a company label when you want to find one tailored version later
- add a year label when you want a simple archive marker
Do not:
- stack several labels if one will do
- use vague endings like
final,final2, orlatestwhen a clearer label would work - treat the filename as the main lever in your resume strategy

What this article is not claiming
The reviewed sources here do not support filename-based ATS ranking, scoring, or parsing claims.
So Blacklight's guidance here is intentionally narrow: treat the filename as an organization and cleanup step, not as evidence about ATS mechanics.
Put more effort into the content of the resume itself.

Rename your file once using a clean pattern, then move on.

FAQ
Short answers for the next obvious questions
What is a safe default resume filename?
A simple Blacklight default is FirstName-LastName-Resume.
When should I add a role, company, or year label?
Use one of those labels only when it helps you stay organized. For example, a role label can help if you keep separate versions for different job families, a company label can help you find one tailored copy later, and a year label can help with archiving.
