Where to find your TSP account number

Your Thrift Savings Plan account number is a five-digit code assigned to you when you open a TSP account. You can find it in three places: your most recent TSP statement, your online TSP account at tsp.gov, or by calling the TSP customer service line at 1-877-968-3778.

The fastest route is logging into your TSP account on tsp.gov. Once you sign in with your username and password, your account number appears at the top of your account summary page. If you do not have online access set up yet, you can register at the same website using your Social Security number and date of birth.

If you have a paper statement from TSP, the account number is printed in the upper right corner of the first page. Statements are mailed quarterly, so if you have not received one recently, the online portal is your quickest option.

Key Takeaways

  • Your TSP account number is a five-digit code that appears on statements, in your online account, and through customer service.
  • The tsp.gov website is the fastest way to find your number if you have already registered for online access.
  • You can register for online access using your Social Security number and date of birth if you do not have a username yet.
  • TSP customer service at 1-877-968-3778 can provide your account number over the phone if you cannot access the website or your statements.

Registering for online access to tsp.gov

If you have never logged into your TSP account online, you will need to create a username and password first. Go to tsp.gov and select "Register" on the login page. You will be asked for your Social Security number, date of birth, and the last four digits of your phone number.

TSP will send a temporary password to the phone number or email address on file with your account. Use that temporary password to log in, then create a permanent password of your own. Once you are logged in, your account number is visible on the account summary page.

Registration usually takes a few minutes. If you run into trouble, TSP customer service can walk you through the process or provide your account number directly.

What your TSP account number is used for

You need your TSP account number when you set up direct deposit, transfer money between accounts, or provide banking information to an employer or financial institution. It is also required if you are rolling over TSP funds to an IRA or another retirement plan, or if you need to contact TSP customer service about your account.

Your account number is not the same as your Social Security number or your employee identification number. TSP uses the five-digit account number to track your contributions, investment choices, and balance across all the funds you hold.

Calling TSP customer service for your account number

If you cannot access tsp.gov or do not have a recent statement, you can call TSP customer service at 1-877-968-3778. The line is open Monday through Friday, 7 a.m. to 7 p.m. Eastern time. Have your Social Security number and date of birth ready when you call.

Customer service representatives can provide your account number over the phone and can also help you register for online access if you need it. Wait times are typically shorter early in the morning or late in the afternoon.

Finding your account number on paper statements

TSP mails quarterly statements to the address on file with your account. Your account number is printed in the upper right corner of the first page, above your name. The statement also shows your current balance, recent transactions, and the value of each fund you hold.

If you have not received a statement in more than three months, your mailing address may be out of date. You can update your address through your online TSP account or by calling customer service. Statements typically arrive within two weeks of the end of each quarter.

What to do if you cannot find your account number

If you have lost access to your statements and cannot log into tsp.gov, the phone line is your most direct option. TSP customer service can verify your identity using your Social Security number and date of birth, then provide your account number when ready.

If you are a new federal employee and have not yet received your first TSP statement or set up online access, contact your agency's human resources or benefits office. They can confirm that your TSP account has been opened and provide guidance on accessing it.
