What Your PA Unemployment Compensation Number Is and Why You Need It

Your Pennsylvania Unemployment Compensation (UC) number is a unique identifier assigned to your claim when you file with the Pennsylvania Department of Labor & Industry. It is not the same as your Social Security number. You will use this number every time you contact the department, file a weekly claim, check your claim status, or communicate with a claims examiner.

The UC number appears on all official correspondence from the state — your initial information letter, weekly claim forms, and payment statements. If you lose this number, you can still retrieve it, but having it on hand from the start saves time and frustration when you need to follow up on your claim.

Key Takeaways

  • Your PA UC number is mailed to you on your initial information letter within one to two weeks of filing your claim.
  • You can find your UC number by logging into your account on the PA UC website, calling the UC Service Center, or checking any official letter from the Department of Labor & Industry.
  • Always have your UC number ready when you call the department, file weekly claims online, or speak with a claims examiner.
  • If you file a new claim after a previous one closes, you will receive a new UC number for that separate claim period.

Where to Find Your UC Number After You File

When you file your initial claim with Pennsylvania, the Department of Labor & Industry mails you a information letter within one to two weeks. This letter contains your UC number in a prominent location — usually near the top or in a box labeled "Claim Number" or "UC Number." Keep this letter in a safe place and refer to it whenever you need the number.

If you filed online through the PA UC website and did not receive a paper letter yet, you can log into your account when ready after filing. Your UC number will display on your account dashboard or in the "Claim Information" section. Write it down or take a screenshot before you close your browser.

How to Look Up Your UC Number Online

The fastest way to retrieve your UC number is through the Pennsylvania UC website at www.uc.pa.gov. Go to the "File a Claim" or "Manage Your Claim" section and log in with your username and password. If you do not remember your login credentials, use the "Forgot Username" or "Forgot Password" link on the homepage.

Once you are logged in, your UC number appears on the main dashboard or in a section labeled "Your Claim Details" or "Claim Summary." You do not need to file anything or answer any questions — you are straightforward viewing information already on file. If the website is down for maintenance (which sometimes happens early morning or late evening), try again a few hours later.

Calling the PA UC Service Center to Get Your Number

If you cannot access the website or prefer to speak with someone, call the Pennsylvania UC Service Center at 1-888-313-7284. This line is open Monday through Friday, 8:00 a.m. to 4:00 p.m. Eastern Time. Have your Social Security number and date of birth ready when you call.

Wait times are often longest on Mondays and Tuesdays. If you reach an automated system first, listen for the option to speak with a representative or to retrieve claim information by phone. A representative can confirm your UC number, answer questions about your claim status, and help you resolve issues with your weekly filings.

What to Do If You Cannot Locate Your UC Number

If you have filed a claim but cannot find your UC number anywhere, do not panic. You can still file your weekly claims and manage your account using your Social Security number and date of birth as alternative identifiers on the PA UC website. The system will prompt you to enter these details if you do not have your UC number.

However, when you call the Service Center or speak with a claims examiner, you will need to provide your Social Security number to verify your identity. Once a representative pulls up your account, they will give you your UC number and you can write it down for future reference. Request that they also mail you a copy of your information letter if you never received the original.

Using Your UC Number for Weekly Claims and Correspondence

Every week you are receiving benefits, you must file a weekly claim form through the PA UC website or by phone. When you log in to file, your UC number may appear automatically if you are using a saved account. If you are filing by phone, have your UC number ready — the automated system will ask for it to pull up your account.

If you receive any letter or notice from the Department of Labor & Industry, reference your UC number in any reply or follow-up call. When you contact the Service Center about a specific issue — a missing payment, a question about your benefits, or a notice you received — providing your UC number helps the representative locate your file when ready instead of searching by name.

Important Details About UC Numbers and New Claims

Each time you file a new claim with Pennsylvania, you receive a new UC number. This happens when your previous claim year ends or when you file after a break in unemployment. Do not assume your old UC number still applies. Check your new information letter for the current UC number associated with your active claim.

If you are unsure whether you have an active claim or whether a previous claim is still open, log into the PA UC website and check the "Claim Status" section. It will show you which claims are active, which are closed, and the UC number for each one. This is especially important if you have worked and filed multiple times over several years.

Frequently Asked Questions

Can I use my old UC number if I file a new claim?

No. Each new claim receives its own UC number. When your claim year ends or you file after returning to work, the state assigns a fresh number. Always use the UC number from your most recent information letter.

What if I lost my information letter and cannot access the website?

Call the PA UC Service Center at 1-888-313-7284 with your Social Security number and date of birth. A representative will retrieve your UC number and can mail you a replacement information letter if needed.

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

Not always. The PA UC website can pull up your account using your Social Security number and password if you are logged in. However, having your UC number on hand speeds up the process and is required if you file by phone.

Will my UC number change if I appeal a decision?

No. Your UC number stays the same throughout your claim, including if you file an appeal or if the state reviews your case. The number identifies your entire claim history, not just one decision.

Is my UC number the same as my claim number?

Yes. Pennsylvania uses the terms interchangeably. Your UC number and your claim number are the same thing — a unique identifier for your unemployment claim with the state.
