Where to find your TSP account number
Your Thrift Savings Plan account number is a nine-digit code that identifies your individual retirement account within the federal employee system. You can find it on your most recent TSP statement, in your online TSP account, or by calling the TSP directly.
The fastest route is to log into your TSP account at tsp.gov using your username and password. Your account number appears at the top of your account summary page and on any statement you download. If you have a paper statement from the last few months, the number is printed in the upper right corner.
If you do not have access to your online account or a recent statement, call the TSP at 1-877-968-3778 during business hours (Monday through Friday, 7 a.m. to 7 p.m. Eastern time). Have your Social Security number and date of birth ready. A representative can read your account number to you over the phone.
Key Takeaways
- Your TSP account number is nine digits and appears on your online account summary, paper statements, and in your account profile at tsp.gov.
- Logging into tsp.gov is the fastest way to locate your number if you remember your username and password.
- If you have lost access to your online account, call 1-877-968-3778 with your Social Security number and birth date ready.
- Your account number is different from your Social Security number and is required when setting up direct deposit, rolling over funds, or contacting TSP about your account.
Recovering a forgotten TSP username or password
If you remember your account number but cannot log into tsp.gov, you can reset your credentials without calling. On the TSP login page, select "Forgot Username" or "Forgot Password" and follow the prompts. You will need to verify your identity using your Social Security number and date of birth.
The reset process takes a few minutes and sends you a temporary password or username reminder by email. Once you have reset your credentials, log in and your account number will be visible on the summary page. If the email reset does not work, call the TSP phone line and a representative can help you regain access.
What your TSP account number is used for
You need your account number when you set up direct deposit for TSP withdrawals, roll over funds to another retirement account, or contact TSP customer service about your account. Banks and financial institutions may also ask for it when you are moving money between accounts or setting up transfers.
Your account number is not the same as your Social Security number, even though both identify you in the federal system. Keep your account number separate from sensitive passwords, but it is safe to share with your employer's payroll office or with TSP representatives when you call.
Finding your account number on paper statements
If you receive paper statements by mail, your account number is printed in the upper right corner of the first page. The number appears in a field labeled "Account Number" or "TSP Account Number" and is always nine digits.
Statements are typically mailed quarterly, though you can request them more often or switch to email delivery through your online account settings. If your most recent statement is more than a few months old, the number has not changed — TSP account numbers remain the same for the life of your account.
What to do if you cannot locate your account number anywhere
If you do not have access to statements, cannot log into your online account, and do not remember your username, the phone line is your only option. Call 1-877-968-3778 and have your Social Security number, date of birth, and a form of government-issued identification ready. The representative will verify your identity and provide your account number.
The call typically takes five to ten minutes. TSP representatives can also update your contact information, reset your online access, or answer questions about your account balance and investment options while you have them on the line.
Keeping your account number secure
Your TSP account number is not classified information, but treat it like you would a bank account number. Do not share it in emails or texts, and do not post it on social media or public forums. When you call TSP or your employer's benefits office, verify that you are speaking to an official representative before providing the number.
If you suspect someone has misused your account number, log into tsp.gov immediately and check your recent transactions. Contact TSP right away if you see withdrawals or transfers you did not authorize. TSP can freeze your account and investigate unauthorized activity.
Frequently Asked Questions
Is my TSP account number the same as my employee identification number?
No. Your TSP account number is specific to your retirement savings account and is nine digits. Your employee ID is a separate number used by your agency for payroll and personnel records. Both are in the federal system, but they serve different purposes.
Can I find my TSP account number through my employer's benefits office?
Yes. Your agency's human resources or payroll office has your TSP account number on file. They can provide it to you if you ask, though logging into tsp.gov yourself is usually faster. Some agencies also print the number on benefits statements or enrollment documents.
What if I have multiple TSP accounts?
Most federal employees have one TSP account. If you have worked for multiple agencies or separated and rejoined federal service, you may have more than one. Log into tsp.gov and check your account list, or call 1-877-968-3778 to confirm how many accounts are in your name.
Do I need my account number to check my balance online?
No. You log into tsp.gov using your username and password, not your account number. Once you are logged in, your account number is displayed on the summary page. You only need the account number if you are contacting TSP by phone or setting up transfers outside the website.
How long does it take to get my account number if I call TSP?
A TSP representative can provide your account number immediately during the call. The entire process usually takes five to ten minutes, depending on how quickly you can verify your identity. Call during business hours Monday through Friday, 7 a.m. to 7 p.m. Eastern time.
