Startup Idea : CV Number

I want to save trees from job seekers and employers. The idea is to have a website/app where job applicants can upload all educational information like degree, certifications, CVs e.t.c and generate a number like phone number or 10 digits to be used for all job hunts. Employers utilize the website/app to look up every qualification about the applicant. No need for paper applications. Employers will ask applicants to send their CV Number to apply in their job postings. The website can also be used by people who are currently employed. Simply log in and update any credentials. CV Number. Remains the same.
