How do I find my employer registration number for unemployment - Washington ESD needs it
I'm trying to file my weekly claim and Washington ESD is asking for my employer registration number. I have no idea where to find this or what it even looks like. My employer laid me off two weeks ago and didn't give me any paperwork with this number on it. I've looked at my pay stubs and W-2 but don't see anything that looks like a registration number. Does anyone know where I can find this or how to get it from my employer? I'm worried my claim will get delayed if I don't have the right information.

The employer registration number is usually on your separation notice or layoff paperwork. If you didn't get that, it should also be on any unemployment-related documents your employer was supposed to give you when they let you go.

•I never got any separation paperwork, they just told me Friday was my last day. Should I contact HR?

•Yes definitely contact HR. They're legally required to provide certain documents when laying people off, including info that helps with unemployment claims.

You can also try calling Washington ESD directly and they can look it up using your employer's business name and address. But good luck getting through - I've been trying to call them for weeks about my adjudication issue.

•Same here, I can never get through to anyone at Washington ESD. The phone system is impossible.

•I actually found a service called Claimyr that helped me get through to Washington ESD agents. They handle the calling for you and get you connected. Check out claimyr.com - they have a video demo at https://youtu.be/7DieNd3C7zQ that shows how it works.

•Interesting, I might have to try that. I'm so tired of sitting on hold for hours just to get disconnected.

The employer registration number is also called the UI account number sometimes. It's a series of numbers that Washington ESD assigns to every employer who pays into the unemployment system. Your employer should have this on file.

•UI account number - that helps! I'll ask HR specifically for that when I call them tomorrow.

•Yeah it's usually like 6-8 digits I think? My employer had it on my final paycheck stub.

If your employer is being difficult about providing it, you can file your claim without it initially. Washington ESD will contact the employer directly to get the information they need. It might delay things a bit but won't stop your claim entirely.

•That's good to know! I was worried my whole claim would get rejected if I didn't have every single piece of info.

•Exactly, Washington ESD deals with missing employer info all the time. They have ways to verify employment even if employers don't cooperate.

Check any old pay stubs too, sometimes it's listed there under employer ID or account number. Also your year-end tax documents might have it.

•I looked at my pay stubs but didn't see anything obvious. Maybe I missed it though, I'll check again for any ID numbers.

•Look for any multi-digit number that isn't your employee ID or social security number. It might be labeled differently.

Your employer is supposed to report your layoff to Washington ESD anyway, so they should already have all the info they need about your employment. The registration number just helps them match everything up faster.

•Oh that makes sense. So even if I can't find it, they should still be able to process my claim?

Freya Andersen
•Yeah, it might just take longer to verify everything. But don't let that stop you from filing as soon as possible.

I had the same problem last year when I got laid off. Turns out my employer never registered properly with Washington ESD and that's why I couldn't find a registration number. Caused a huge mess with my claim.

Hiroshi Nakamura
•Oh no, how did you find out they weren't registered? What happened to your claim?

•Washington ESD told me after investigating. My claim got delayed by like 6 weeks while they sorted it out with my employer. Eventually got all my back pay though.

If you need to talk to someone at Washington ESD about this, I had success using Claimyr to get through their phone system. They got me connected to an agent who could look up my employer's registration number using just the company name and address.

•How does Claimyr work exactly? Do they charge for the service?

•They handle all the calling and waiting on hold for you. Much easier than trying to get through myself. The video demo on their site explains it better than I can.

Some employers put the registration number on their quarterly wage statements too. If you have access to any employee portal or HR documents online, check there.

Hiroshi Nakamura
•Good idea, I think I can still access our employee portal for a few more days. I'll check for any wage statements.

Diego Fernández
•Yeah definitely check before they cut off your access. Most companies disable that pretty quickly after layoffs.

The registration number might also be on any COBRA paperwork if they offered you continued health insurance. Those documents usually have all the employer identification numbers.

•I did get COBRA info! I'll dig through those papers tonight. Thanks for the tip.

•Hope that helps! COBRA paperwork usually has way more employer details than regular HR stuff.

honestly the whole system is so confusing, why do they need so many different numbers and IDs for everything? like can't they just use the business name??

Leila Haddad
•Multiple businesses can have similar names, so the registration numbers help Washington ESD keep everything organized and prevent mix-ups with claims.

•i guess that makes sense but still annoying when youre trying to file and dont have all these random numbers

I work in HR and can tell you that every employer should have their Washington ESD registration number readily available. If they're giving you the runaround, that's a red flag that they might not be handling their unemployment obligations properly.

•What should I do if my employer refuses to give me the number or says they don't have it?

•Contact Washington ESD directly and report the issue. They take employer non-compliance seriously and will investigate. Don't let it delay your claim filing though.

Try looking at your state tax withholdings on old pay stubs. Sometimes the employer registration number is listed there along with other state identifiers.

•I'll check the tax section of my pay stubs more carefully. I might have overlooked it there.

•Yeah it's usually in small print but it should be there somewhere if they're properly reporting wages.

Does anyone know if the registration number is the same as the FEIN or EIN? My employer gave me their federal tax ID but I'm not sure if that's what Washington ESD wants.
0 coins
Leila Haddad
•No, the Washington ESD registration number is different from the federal EIN. The EIN is for federal taxes, the registration number is specifically for state unemployment insurance.

•Thanks for clarifying! I was about to use the wrong number on my claim.

I remember when I filed, Washington ESD's website had a lookup tool where you could search for employers by name to find their registration info. Not sure if it's still available but worth checking.

•That would be amazing if they have that! I'll look around their website for any employer search tools.

Just wanted to follow up - I used Claimyr yesterday to get through to Washington ESD and they found my employer's registration number in like 2 minutes. Way easier than trying to get it from my old job. Totally worth it if you're stuck.

•That's great to hear! I might try them if I can't track down the number on my own. How quickly did they get you connected?

•It was pretty fast, maybe 20 minutes total including the time they spent on hold for me. Much better than the hours I wasted trying to call myself.

Update: I found my employer registration number on my final paycheck! It was listed under state withholdings as 'UI Acct' followed by the number. Thanks everyone for the suggestions about where to look.

For anyone else looking for this info - I called my payroll company directly (not HR) and they had the registration number right away. Sometimes the payroll vendor has better records than the company itself.

•Smart thinking! I know we used ADP for payroll, I could try calling them if I can't find the number elsewhere.

•Exactly, ADP, Paychex, all those companies keep detailed records of employer registrations. They might be more helpful than your actual employer.

Another thing to try - if you have any old W-2 forms from your employer, sometimes the registration number appears in the state wage reporting section. It might be labeled as "State ID Number" or "SUTA Account Number" (State Unemployment Tax Act). I found mine there when I couldn't locate it anywhere else. Also, if you received any notices about workplace injuries or workers comp in the past, those documents sometimes include the employer's various state registration numbers too.
