NOC — National Occupational Classification
Canada's standardized system for classifying every occupation by a 5-digit code and a TEER category. Most economic-class immigration applications require you to identify the NOC code that matches your work experience.
What is the NOC?
The National Occupational Classification (NOC) is the system Canada uses to classify and describe every occupation in the labour market. Each occupation has a unique 5-digit code and is mapped to a TEER category (0 through 5) reflecting the typical training, education, experience, and responsibility level for the job.
Almost every economic-class immigration application requires you to identify the NOC code that best matches the duties of your work experience — not just the job title.
How is the NOC structured?
A NOC code looks like this: 21232 — Software developers and programmers.
- First digit = TEER category (0-5)
- Second digit = Broad occupation category
- Last three digits = Specific occupation
The current NOC version is NOC 2021 (in effect since November 2022). It replaced NOC 2016, which used 4-digit codes and a "Skill Level" classification. The 2021 version reorganized the system and introduced TEER categories.
Why does NOC classification matter?
- Express Entry eligibility. CEC requires 12+ months of TEER 0-3 work; FSW requires 1+ year continuous TEER 0-3 work; FSTC requires TEER 2 or 3 in specific skilled trades.
- LMIA-supported work permits. The Labour Market Impact Assessment process requires matching the job offer to a specific NOC code and TEER level.
- Category-based Express Entry draws. Categories like Healthcare, STEM, Trades, Transport, Agriculture, and Education are defined by specific NOC code lists.
Common gotchas
- Duties, not titles. Officers compare your reference-letter duties against the NOC's "main duties" list. If your title is "Manager" but your duties match a non-manager TEER 2 NOC, the manager NOC will be rejected.
- NOC misclassification = refusal risk. Choosing the wrong NOC is one of the leading causes of Express Entry application refusals. The duties must align with the NOC's official description.
- NOC 2021 transitions. Some pre-November-2022 work experience under NOC 2016 codes maps to different TEER levels under NOC 2021. We verify the mapping for transitional files.
- Reference letter language. A strong reference letter quotes or paraphrases the NOC's "main duties" statements directly, supported by pay stubs, contracts, and tax records.
