Your claim number is the reference code the state assigns when you file for unemployment

When you file for unemployment in Massachusetts, the Department of Unemployment information (DUA) gives you a unique claim number. This number identifies your case in their system and appears on every piece of correspondence they send you — approval letters, payment notices, and denial letters. You will need this number to check your claim status, report your weekly earnings, and contact DUA about your account.

The claim number is not the same as your Social Security number or driver's license number. It is a separate identifier created just for your unemployment case. If you file multiple times over several years, you may receive a different claim number each time, because each filing period gets its own case file.

Key Takeaways

  • DUA sends your claim number by mail within one to two weeks of filing, or you can find it when ready in your online account if you filed through the MassLaborID portal.
  • The claim number appears on your approval letter, payment notices, and any official communication from DUA about your case.
  • You must provide your claim number when you call DUA customer service, report weekly earnings, or request a payment status update.
  • If you lose your claim number, you can retrieve it by logging into your MassLaborID account or calling DUA's main line and providing your Social Security number and date of birth.

Where to find your claim number after you file

If you filed online through the MassLaborID portal, your claim number appears when ready on the confirmation screen after you submit your process. Write it down or take a screenshot before you close the browser. This is the fastest way to get your number — you do not have to wait for mail.

If you filed by phone or in person at a DUA office, the state mails your claim number to the address on file within one to two weeks. The letter will say "Notice of Claim Filing" or "information of Unemployment Insurance Claim" and will include your claim number in large print near the top of the page. Keep this letter in a safe place; you will refer to it many times.

You can also log into your MassLaborID account at any time after filing and view your claim number in the "My Claims" section. This is useful if you did not save the confirmation number or if your mailed letter has not arrived yet.

How to use your claim number to check your status

To check whether your claim was approved or denied, log into MassLaborID and select your claim from the list. The status will show as "Approved," "Pending," "Denied," or "Under Review." You can also see the date DUA made the decision and any notes about next steps.

If you want to speak to someone at DUA by phone, have your claim number ready before you call. The customer service representative will ask for it to pull up your file quickly. Without it, they will need your Social Security number and date of birth instead, which takes longer.

Your claim number also appears on your payment notices and debit card statements. If you receive a payment, the notice will show which week the payment covers and your claim number so you can match it to your records.

Reporting weekly earnings with your claim number

In Massachusetts, you must report your earnings every week you receive unemployment benefits, even if you earned no money that week. You do this through the MassLaborID portal or by phone. Your claim number is required to file your weekly report.

When you log into MassLaborID to report earnings, the system will show your claim number at the top of the page. You select the week you are reporting for, enter your gross earnings (before taxes), and submit. The system records your claim number with that report so DUA can match it to your account.

If you report by phone, you will dial DUA's automated system and enter your claim number when prompted. The system uses this to locate your account and pull up the weeks you owe reports for. If you do not have your claim number when you call, you can provide your Social Security number instead, but the process is slower.

What to do if you cannot find your claim number

If you filed online and did not save your confirmation number, log into MassLaborID with your username and password. Go to "My Claims" and your claim number will be listed there. This is the fastest way to retrieve it without calling.

If you filed by phone or in person and have not received your mailed notice yet, you can call DUA's main customer service line at 1-877-626-6800. Have your Social Security number and date of birth ready. The representative will look up your claim number and read it to you over the phone. You can also ask them to mail a replacement notice if your original letter was lost.

If you have an old unemployment claim from a previous year, that claim number will not work for your current filing. Each new claim gets a new number. Do not use an old claim number when reporting earnings or contacting DUA about your current case.

Common mistakes with your claim number

The most common error is confusing your claim number with your Social Security number or benefit year number. Your claim number is unique to each filing and is usually shorter — often six to eight digits. Your benefit year is the 12-month period during which you can receive benefits, and it is different from your claim number.

Another mistake is using an old claim number for a new filing. If you filed for unemployment last year and are filing again this year, you have a new claim number. The old number will not work for your current case. Always verify you are using the number from your most recent filing.

Some people provide their claim number incorrectly when calling DUA because they misread it from their letter. Double-check the number before you call, and if the representative says the number does not match your account, read it back slowly digit by digit to make sure you said it right.

Frequently Asked Questions

Can I use my claim number to check my payment status online?

Yes. Log into MassLaborID, go to "My Claims," and select your claim. You will see a payment history showing all payments issued, the weeks they cover, and the amounts. You can also see pending payments and the expected deposit date if your payment has been processed but not yet deposited.

What if I filed multiple times and have more than one claim number?

Each filing period has its own claim number. If you filed in 2022 and again in 2024, you have two different claim numbers. When you contact DUA or report earnings, use the claim number from your current filing. Your old claim numbers are still in the system but only explore to those past benefit years.

Do I need my claim number to file my weekly report?

If you file through MassLaborID online, the system automatically knows which claim you are reporting for once you log in. If you call the automated phone line, you will need to enter your claim number. Having it ready makes the process faster, but you can also use your Social Security number if you do not have it.

Will DUA send me my claim number by email or text?

No. DUA sends your claim number by mail to your address on file and displays it in your MassLaborID account. They do not send it by email or text message. If someone contacts you claiming to be from DUA and asks for your claim number via text or email, do not respond — it is a scam.

What should I do if I think someone else is using my claim number?

Call DUA when ready at 1-877-626-6800 and report the suspected fraud. Have your claim number and Social Security number ready. DUA can freeze your account and investigate. You can also file a report with the Massachusetts Attorney General's office if you believe your identity has been stolen.
