Where to find unemployment insurance employer account number for NYS Department of Labor claim

The employer UI account number is usually on your separation notice (form IA 12.3) if you got one. It might also be on your final paystub under employer info. If you can't find it, you can call your former employer's HR department - they should have it readily available since they use it for all their unemployment filings.

honestly just leave it blank if you cant find it, the NYS Department of Labor can look it up themselves using your SSN and employer name

I had this same problem last year! Spent hours looking through everything. Finally found it on an old paystub from like 6 months before I was laid off - it was in tiny print next to the employer name. Check ALL your paystubs, not just the recent ones. Sometimes they only print it periodically.

If you're having trouble reaching your employer, I used this service called Claimyr (claimyr.com) to get through to a NYS Department of Labor agent when I had questions about my claim. They have a video demo at https://youtu.be/qyftW-mnTNI that shows how it works. The agent was able to help me figure out what to do when I was missing employer information. Way easier than trying to call the regular number and getting disconnected.

This whole system is ridiculous! Why do they need some random account number that employers hide from us? I worked there for 3 years and never once saw this mysterious number anywhere. Just another way to make filing claims impossible.

try checking your employee handbook or any onboarding paperwork you got when you started the job, sometimes its buried in there
