Is a retail shop owner eligible for express entry
And if yes
What is the NOC code for that
Yes. You can claim points for self-employment and provide the following evidence:

"if the applicant is self-employed, articles of incorporation or other evidence of business ownership, evidence of self-employment income and documentation from third-party individuals indicating the service provided along with payment details (self-declared main duties or affidavits are not acceptable proof of self-employed work experience)."
