The Office of Personnel Management (OPM) is a federal agency that works like the human resources department for the entire U.S. government. It was created in 1979 and handles matters related to federal employees, retirement systems, and health insurance programs for government workers. OPM operates under the Executive Branch and reports to the President.

The agency manages several critical functions that affect millions of people. OPM oversees the Federal Employees Retirement System (FERS), the Civil Service Retirement System (CSRS), and the Federal Employees Health Benefits Program (FEHBP). It also conducts background investigations and security clearance processing for federal positions. Additionally, OPM sets standards for federal employee pay, benefits, and workplace policies.
Understanding what OPM does helps you know which office or department can actually handle your specific needs. For example, if you have questions about federal employee retirement, OPM is the right contact. If you worked for a private company, you would contact your employer's human resources department instead. OPM specifically serves current federal employees, former federal employees, retirees, and their families.
The agency also manages federal employee training and development programs. OPM maintains job classifications for federal positions and provides guidance on federal hiring practices. It sets rules about how federal agencies must treat their employees regarding pay, leave, and working conditions. When Congress passes laws affecting federal workers, OPM often creates the detailed rules that agencies must follow to implement those laws.
Practical Takeaway: Before contacting OPM, determine whether your question relates to federal employment, federal retirement, or federal employee health insurance. If you worked for a private company, a state or local government, or a non-federal organization, you likely need to contact a different agency or your former employer instead.
OPM offers several ways to reach the agency, depending on your specific question and preferred communication method. The organization maintains a central phone line, website, mailing address, and regional offices that serve different geographic areas. Knowing which contact method works best for your situation can save time and help you reach the right department more quickly.

The main OPM phone line is 202-606-1800. This number connects to the general information office during business hours, Monday through Friday, 8:30 a.m. to 5:00 p.m. Eastern Time. The phone line can direct your call to specific departments within OPM based on your question. However, wait times can be lengthy during busy periods, particularly early in the week and early in the month when many people contact the agency.
OPM's official website is www.opm.gov. The website contains extensive information organized by topic, including retirement, health insurance, federal employment, and pay scales. You can search for specific topics, read frequently asked questions, and access forms and publications without contacting the agency directly. Many common questions can be answered through the website resources before you need to call or write.
You can mail written inquiries to: Office of Personnel Management, 1900 E Street NW, Washington, D.C. 20415. Mail should clearly state your question and include relevant information such as your name, agency where you worked, dates of employment, and any employee identification numbers if applicable. Mailed inquiries typically take 2-4 weeks for a response, so this method works best when your question is not time-sensitive.
OPM also maintains regional offices in major cities across the United States. These offices can handle in-person inquiries about retirement, health insurance, and employment matters. Regional offices provide the advantage of face-to-face communication and the opportunity to ask follow-up questions directly. You can locate your nearest regional office on the OPM website by entering your state or zip code.
Practical Takeaway: Start with the OPM website to search for information about your specific question. If you cannot find the answer online, use the phone line for immediate concerns or mail your inquiry for detailed questions that are not time-sensitive. Consider visiting a regional office if you prefer in-person communication and live near one.
One of the most common reasons people contact OPM is to ask questions about federal retirement. Federal employees participate in either the Federal Employees Retirement System (FERS) or the Civil Service Retirement System (CSRS), depending on when they were hired. Retirement rules are complex because they involve multiple factors including length of service, age, and type of employment.

If you are a current federal employee with questions about how much retirement benefit you might receive, contact OPM's Retirement Services division at 202-606-0500. This line can direct you to staff who can discuss your specific situation. You can also request a retirement estimate from OPM. Your request should include your name, date of birth, federal agency, job series, and years of service. OPM uses this information to calculate an estimate of your monthly retirement benefit.
If you are already retired and receiving a federal pension, your retirement payments are managed by the National Finance Center (NFC), which operates under OPM. If you have questions about your current retirement payment amount, your Thrift Savings Plan (TSP) account, or benefits for your survivors, you may need to contact NFC at 1-800-400-0395 rather than the main OPM line. NFC handles payment processing and account management for retired federal employees.
Former federal employees who left government service before becoming eligible for retirement can request information about their service record and future retirement options. Even if you did not work long enough to receive a federal pension immediately, you may have rights to your own contributions or survivor benefits. OPM can provide information about what happens to your retirement account if you left federal service. You can request this information by contacting OPM's Retirement Services at the phone number listed above or by submitting a written request with your name and former agency.
Common retirement questions include whether military service counts toward federal retirement, how part-time work affects benefits, whether benefits are reduced if you work after retirement, and how survivor benefits work. OPM maintains a comprehensive retirement page on its website with answers to many of these questions. The website includes benefit calculators and publications explaining retirement rules in detail.
Practical Takeaway: Gather your employment records before contacting OPM about retirement, including your dates of service, job series, and agency. If you need to verify what OPM has on file about your service, submit a written request for your Official Personnel Folder (OPF), which contains your complete employment history.
Federal employees and retirees receive health insurance through the Federal Employees Health Benefits Program (FEHBP). This program offers coverage to current and retired federal workers and their families. OPM oversees FEHBP but does not process individual health insurance claims or enrollment matters directly. Instead, individual insurance carriers handle most benefits questions.

If you are a current or retired federal employee with a question about your health insurance coverage, your first step should be to contact your specific insurance carrier rather than OPM. Your insurance card shows the carrier's phone number. The carrier can answer questions about coverage, claims, deductibles, and finding providers within your plan's network. Insurance carriers employ customer service representatives who specialize in answering benefits questions and can often resolve issues immediately.
However, if your question concerns the FEHBP program itself, general rules about how the program works, or which plans are available during open season, you should contact OPM. You can call 202-606-0500 and ask to speak with someone in the FEHBP office, or you can visit www.opm.gov/healthcare-insurance, which contains detailed information about the program, plan comparisons, and enrollment instructions.
Open season for federal health insurance typically runs from November through December each year. During this period, federal employees and retirees can change their health insurance plan for the coming year. OPM publishes information about available plans, premium costs, and plan changes before each open season begins. If you miss the regular open season, you may still change plans if you experience certain life events such as marriage, birth of a child, loss of other coverage, or retirement. OPM has rules about which events allow plan changes and what documentation you must submit.
Life insurance for federal employees is handled through the Federal Employees Group Life Insurance (FEGLI) program, which OPM also oversees. Long-term care insurance is available to federal
