How to find your NOC code (and why yours may be wrong)

Almost every question about Canadian economic immigration eventually reduces to one thing: which National Occupational Classification code describes your work.

The NOC code decides which of the three Express Entry programs you can qualify for. Since the 2026 overhaul, it also decides which category-based rounds you can be invited in — and those categories are defined as lists of NOC codes, not as industries. Get the code wrong and everything built on top of it is wrong too.

It is also the single most common thing people assume rather than check.

What TEER is

NOC 2021 organises occupations by TEER — Training, Education, Experience and Responsibilities. There are six levels, numbered 0 to 5:

TEER matters because program eligibility is written in terms of it. It is not a ranking of how valuable the work is, and it is not a judgement about the person doing it — it is a classification of what the occupation typically requires.

Duties decide the code, not your job title

This is the part that catches people out, and IRCC states it plainly: make sure the main duties listed match what you actually did. If they do not, the code is not yours, and you need to find one whose duties do match.

Job titles are not standardised. Two people with “Project Manager” on their contract can belong under different NOC codes, and someone whose title is “Analyst” may be performing the duties of an occupation classified quite differently. Employers invent titles; the NOC does not recognise them.

What IRCC is comparing against is the NOC entry’s lead statement and its main duties list. A reference letter that recites your job title tells them nothing. A reference letter that describes duties matching the NOC entry is the evidence that does the work.

How to check it properly

1. Search your job title on IRCC’s NOC table to get a shortlist of candidate codes.
2. Open each candidate on the NOC site, using NOC 2021 Version 1.0, and read the lead statement and main duties in full.
3. Compare them against what you actually did day to day — not what your title was, and not what your employer’s org chart said.
4. If the duties do not line up, keep looking. A near-miss is a miss.
5. Write down the code, the official occupation title and the TEER level, and use those consistently everywhere.

If two codes look plausible, that is a real question rather than a formality. It is one of the more common things worth a consultation, because the answer can change which programs and categories are open.

Why this matters more since 2026

Category-based selection made the NOC code load-bearing in a way it was not before.

The Express Entry categories are published as tables of NOC codes. Being “in healthcare” or “in tech” as a matter of ordinary language is irrelevant — what counts is whether your code appears on the list. The STEM category, for instance, contains eleven occupations and does not include software developers or data scientists, which surprises most people who work in technology.

It also cuts the other way. IRCC’s category rules say the qualifying experience counts regardless of your primary occupation. Someone who has moved into a role outside every category list may still hold twelve months of qualifying experience in a listed occupation from earlier in their career. That only becomes visible if the earlier work has been classified properly.

Common mistakes

Using the code an employer or recruiter supplied. Employers classify roles for their own purposes, including for an LMIA, and those purposes do not always line up with what your experience supports.

Copying a code from someone with the same job title. Titles are not the unit of classification.

Using a 2016 NOC code. The 2021 version replaced four-digit codes with five digits and replaced skill levels with TEER. Older codes and older guides are still widely circulated.

Choosing the code that looks best rather than the one that fits. A code has to be supportable by reference letters describing real duties. A flattering classification you cannot evidence is worse than an accurate one.

Before you rely on this

This is general information about how the classification system works. Which code applies to a particular person’s history is a question about that person’s actual duties and documents, and this page cannot answer it. IRCC’s pages are the authoritative source, and the NOC is revised — check the version in force when you apply.
