What does it mean to 'check' a NOC code?

Checking a NOC code means verifying that the lead statement and main duties of the NOC 2021 code you selected actually describe your real job. IRCC officers do this manually when they review your Express Entry or PNP application — if the duties on your reference letter don't match, your work experience is rejected.

How accurate is an automated NOC code checker?

Check My NOC compares the exact phrasing of your reference-letter duties against the official ESDC main-duties list using semantic matching. It produces a percentage match and flags duties that fall outside the NOC's scope. It is not legal advice, but it is the same comparison an IRCC officer performs.

What is a 'good' NOC duty match score?

A duty match of 80% or higher is strong. 70–79% is acceptable but means your reference letter should be sharpened. Below 70% is risky — you should either rewrite the reference letter to mirror the NOC's main duties more closely, or pick a different NOC.

How to check your NOC code before you apply for PR

Picking a NOC code is only half the job. Before you submit Express Entry or your PNP application, you need to check that the duties on your employment reference letter actually match the official main duties listed on noc.esdc.gc.ca. This is the single most common reason work experience is refused by IRCC.

Knowing your NOC code is only half the equation. IRCC doesn't ask what your code is — they ask whether your reference letter duties prove it. Most refusals at the eligibility stage aren't wrong NOC codes, they're correct codes (like your claimed NOC for PR applicants) with reference letters that don't back them up.

A NOC code that doesn't match your actual duties isn't just a paperwork issue — IRCC can treat it as misrepresentation, which carries consequences that go well beyond a single refused application.

Confirming your NOC code before you submit is a lot cheaper than correcting it after.

Educational information only, not legal advice. Consequences vary based on individual circumstances.

Real example: A Business Analyst applicant claimed NOC 21221 but their reference letter described gathering requirements and writing user stories, none of the systems-analysis duties in the NOC. Refused at the eligibility stage.

What IRCC actually checks

Per the IRCC IRCC operational bulletin on Express Entry completeness check, an officer reads your reference letter and verifies two things: that you performed the actions described in the lead statement of your NOC, and that you performed a substantial number of the main duties listed for that NOC. Vague duty descriptions — "responsible for development", "handled clients" — trigger a procedural fairness letter and often a refusal.

The 4-step NOC code check

Pull the official duties. Open your NOC's page on noc.esdc.gc.ca and copy the lead statement and every bullet under "Main duties".
Pull your reference-letter duties. Copy the bulleted duties from your employment reference letter exactly as written.
Score the overlap. Mark each NOC duty as covered, partially covered, or missing from your letter. Aim for 80%+ coverage of the main duties.
Fix gaps before submission. Either ask your employer to update the reference letter so its phrasing mirrors the NOC main duties, or switch to a closer-fitting NOC code.

Skip the manual work — use the NOC checker

Check My NOC automates the whole process. Paste your duties, enter your NOC code, and get a percentage match plus a duty-by-duty breakdown in about 30 seconds. The Match + alternatives plan also ranks every NOC with 70%+ duty alignment so you can compare codes side by side.

What IRCC actually checks

What surprises most applicants: IRCC officers compare your reference letter duty lines word-by-word against the official NOC duty list. Generic phrases like “managed projects” or “supported the team” fail this check every time.

IRCC refused 23% of Express Entry applicants at the eligibility stage. A $9.99 check is insurance against a $1,500+ mistake.

Your reference letter is the only thing IRCC reads

Score it duty-by-duty against the official NOC 2021 lead statement in 30 seconds — anything under 70% is meaningful refusal risk.
