How to Track Your OPM Retirement Application Status in 2026: CSA Number, Interim Pay, and Services Online

‍

You can check your OPM retirement application status three ways: log in to OPM Retirement Services Online with your CSA number, call the OPM Retirement Information Office at 1-888-767-6738, or email retire@opm.gov. OPM, the U.S. Office of Personnel Management, assigns you a Civil Service Annuity (CSA) claim number once it receives your complete package from your agency.
‍

That seven-digit number always begins with the letters "CSA." It's your primary reference for tracking your case with OPM and getting post-receipt status information.
‍

Have you recently retired from federal service and found yourself watching your bank account for a pension that hasn't arrived? You're not imagining the delay. This guide shows you how to find your CSA number, how to read your status in Services Online, what interim pay is and when it starts, and what to do when the process stalls.
‍

The core process details and current processing figures below come from official OPM guidance available as of August 2026. Any third-party commentary is identified where used.
‍

What "OPM Retirement Application Status" Actually Means
‍

Your OPM retirement application status is the current processing stage of your federal retirement claim after it leaves your agency and reaches OPM. It moves through distinct phases: intake, interim pay authorization, specialist review and annuity calculation, and finalization.
‍

Each phase has its own timeline. You can monitor most of them through OPM Retirement Services Online once your CSA claim number is issued. Knowing which phase you're in tells you what to expect next, and whether a delay is normal or a signal to follow up.
‍

Here's a critical point that trips up many new retirees. OPM can't begin anything until your former agency's human resources and payroll offices finish their part. According to OPM.gov, OPM can't start processing your application until your agency HR and payroll provider send your full employment and pay history, which on average takes about 30 days after your retirement date just to reach OPM.
‍

Step 1: Get and Record Your CSA Number
‍

Your CSA number, short for Civil Service Annuity claim number, is your permanent reference code for everything tied to your federal annuity. Use it every time you contact OPM about your benefits.
‍

When OPM receives your retirement application, it notifies you and provides a seven-digit number preceded by "CSA." According to OPM.gov, you should receive your case number within approximately 30 days after OPM receives your completed retirement application.
‍

Your agency and payroll provider need time to transmit your package first, on average about 30 days after your retirement date just to reach OPM. Plan for both steps rather than a single fixed window.

‍

Where to find your CSA number:
‍

• Your welcome letter. OPM mails this shortly after receiving your package from your agency. The claim number appears in the top-right area of the letter.
  
  
• Your retirement card. The claim number is on the front of the card included with the welcome letter.
  
  
• Any OPM correspondence. The CSA number is included in all correspondence OPM sends you, including your interim pay notice.
  
  
• Your 1099-R, annual COLA notice, or Benefits Booklet. If you're already an annuitant, according to OPM.gov, your CSA or CSF claim number appears on each of these documents.

‍

Step 2: Check Your Status in OPM Retirement Services Online
‍

OPM Retirement Services Online is a secure website that lets you track your retirement claim and manage your annuity account. It's the fastest way to see where your case stands without waiting on hold.
‍

According to OPM.gov, non-disability annuitants can view the status of their annuity application while receiving interim payments through Services Online. To get in, you need the CSA number OPM issued to you.
‍

Here's how access works, per OPM.gov:
‍

• Did you use the same Login.gov account for your Online Retirement Application (ORA) that you use for Services Online? If so, you can log in directly.
  
  
• If OPM didn't have your email address when you applied, you'll receive a welcome letter by mail with login instructions.
  
  
• You'll need a Login.gov account with two-factor authentication. If you don't have one, create it to access Services Online.

Once inside, you can see updates on your case, including when OPM assigns you to a specialist and when it completes your case. You can also update your mailing address, email, and direct deposit information. According to OPM.gov, Services Online displays your application status, such as "Retirement Application Received," along with the date of the action.

Step 3: Understand Interim Pay

Interim pay is a partial annuity OPM issues while it finishes calculating your full pension. It's meant to give you partial retirement income during the review period. OPM notes there are rare situations where an applicant may not be authorized to receive interim payments.

According to OPM's Retirement Quick Guide, interim payments are typically 60% to 80% of your estimated net annuity, enough to help cover your expenses while you wait. Interim pay processing starts once OPM receives your complete retirement application package from the agency. It applies to those who apply for immediate retirement: voluntary, early voluntary, discontinued service/involuntary separation, and approved disability retirements.

Two things interim pay does not include are worth flagging now, because they surprise retirees later:
‍

• It doesn't include the FERS Special Retirement Supplement (SRS), the bridge benefit some FERS retirees receive before age 62.
  
  
• Your survivor annuity election is made as part of your retirement application and reviewed as OPM finalizes your annuity calculation. It's not something that "starts" during interim pay.

FERS, the Federal Employees Retirement System, and CSRS, the Civil Service Retirement System, are the two federal retirement systems. Your interim payment is based on an estimate under whichever system covers you, then trued up when your case completes.

Step 4: Know the Real Timeline

OPM publishes current processing averages. They're the best baseline for judging whether your wait is normal.

According to the OPM retirement processing times page (reflecting cases processed in July 2026), interim pay is set up in an average of 6 days after OPM receives your complete package. Immediate retirements take an average of 109 days to fully process. OPM notes these are averages. Cases involving a court order, special computation, workers' compensation, or missing documentation can take longer.

Here's how the official OPM stages line up against real-world experience.

OPM retirement processing stages and timelines

It helps to understand what those published averages do and don't measure. According to OPM's Retirement Quick Guide, the overall retirement process typically runs about three to five months from separation to your first full annuity payment. OPM warns that court orders, special computations, workers' compensation, missing documents, and similar complexities can extend it further.

OPM's published figures also start the clock only after your agency sends your file. The weeks your package spends in your own HR and payroll offices aren't counted in those numbers, which is why your personal experience can run longer than the headline averages suggest.

Step 5: What to Do When Your Application Stalls

Has your timeline clearly exceeded the averages? Take these steps in order:
‍

1. First 45 days: follow up with your agency. Until OPM receives your file and assigns a CSA number, your case sits with your agency's HR and payroll offices. OPM confirms it can only help after your application is received and a claim number is assigned.
   
   
2. After your CSA number is assigned: check Services Online first. Most status questions are answered there without a phone call.
   
   
3. Contact OPM if your case is beyond its published benchmarks. If OPM has received your complete application and interim pay hasn't started within OPM's stated timeframes, check Services Online first, then call the Retirement Information Office at 1-888-767-6738 for a status update. The line is open Monday through Friday, 7:40 a.m. to 5:00 p.m. ET, excluding federal holidays. According to OPM.gov, the busiest window is between 10:30 a.m. and 1:30 p.m. ET, so call early or late.
   
   
4. Email or mail for documented follow-up. Email retire@opm.gov, or write to the Retirement Operations Center, U.S. Office of Personnel Management, Post Office Box 45, Boyers, PA 16017. Include your full name, phone number, email, claim number, and signature.
   
   
5. Build a cash reserve before you retire. Interim pay may be lower than your finalized annuity, and processing can take several months. Keep a cash reserve sized to your expenses and expected retirement-processing timeline, so a delayed pension is less likely to disrupt your finances.

Federal Employee Advisor Network, a retirement planning firm specializing in federal employee benefits, helps federal employees model their interim-pay cash flow and retirement timing before their final workday, so the processing gap is planned for rather than survived.

Planning Around the Gap: A Real-World Scenario

Picture a FERS employee who separates in January with an estimated net monthly annuity of $4,000. During processing, interim pay at roughly 70% would deliver about $2,800 per month, a $1,200 monthly shortfall.

If finalization takes five months, that's a roughly $6,000 illustrative cash-flow gap before final reconciliation. Your actual adjustment payment can differ based on the finalized annuity, any deductions, and premiums owed for health and life insurance. This is exactly the kind of shortfall a planned cash reserve is designed to absorb.

You can also use the Thrift Savings Plan (TSP), the federal government's tax-advantaged retirement savings program, to bridge income during the wait. Withdrawal timing carries its own tax consequences worth reviewing with a professional.

Federal Employee Advisor Network builds this gap analysis directly into its pre-retirement consultations, so the interim period is funded before it begins.

The Bottom Line

Tracking your OPM retirement application status comes down to one reference code, your CSA number, and one primary tool, OPM Retirement Services Online. Get the number, create your Login.gov access, and check your status there before reaching for the phone.

Interim pay is typically around 60% to 80% of your estimated annuity. OPM's current published average for setting it up is a matter of days after it receives a complete package, though individual cases can take longer. Plan for full processing to take months rather than weeks. Above all, keep a cash reserve so the gap between interim and full pay is less likely to disrupt your retirement finances.

Want your interim-pay shortfall, TSP strategy, and retirement timing mapped out before your last day? Federal Employee Advisor Network, a retirement planning firm specializing in federal employee benefits, can build that plan with you. Schedule a consultation with a federal retirement specialist to plan for the potential cash-flow gap caused by retirement-processing delays.
