——————————————————————————–
Trying to mail a prescription, submit a paper claim, or send a formal appeal to CVS Caremark? You need the right address — and CVS Caremark uses different mailing addresses for different purposes. Just as importantly, those addresses can vary by plan and change over time, so sending something to the wrong location can delay processing by weeks. This guide explains the types of CVS Caremark address you might need, how to tell them apart, and — most importantly — how to confirm the correct, current one for your plan before you mail anything.
Why You Should Verify the Address First
Here is the single most important point on this page: CVS Caremark is one of the largest pharmacy benefit managers (PBMs) in the country, and it routes different functions through different processing centers, some of which are assigned per plan or per employer. That means the mail-order, claims, or appeals address that is correct for one member may be wrong for another. Published P.O. boxes also get retired and replaced. For example, mail-order prescription forms have listed fulfillment addresses in different cities depending on the plan, and claim/appeal P.O. box numbers have shifted over time.
Because of this, treat any CVS Caremark address you find online — including the illustrative examples below — as something to confirm, not as guaranteed-current. The authoritative sources are, in order: the address printed on the specific form or letter CVS Caremark sent you, your member ID card, your plan documents, and the official caremark.com portal after you log in. When in doubt, call the number on your card and ask the representative to confirm the exact mailing address for your purpose.
The Different Types of CVS Caremark Address
Rather than a single address, think in terms of purposes. CVS Caremark generally maintains separate addresses for each of the following.
Corporate Headquarters
CVS Health, the parent company of CVS Caremark, is headquartered in Woonsocket, Rhode Island. This corporate address is appropriate only for general corporate correspondence, investor relations, or media inquiries. It is not for submitting prescriptions, claims, or appeals — sending member paperwork there will only cause delays.
Mail-Order Pharmacy
If you need to mail a paper prescription to CVS Caremark’s mail-order pharmacy, the correct address depends on your plan and can point to different fulfillment facilities (member forms have listed locations such as Palatine, IL and San Antonio, TX, among others). Rather than copying a P.O. box from a general web page, use the mail-service order form provided in your own plan materials or downloaded from caremark.com, which prints the address that applies to you.
Whatever the address, include your member ID number, date of birth, and physician’s contact information with any mailed prescription. Processing times for mailed prescriptions are longer than electronic submissions. Before mailing, confirm your plan covers mail order; most CVS Caremark plans offer a 90-day supply through mail order at a lower copay than retail. For questions, call the CVS Caremark number on your benefit card.
Claims (Direct Member Reimbursement)
If you paid out of pocket for a covered prescription and need reimbursement, you will mail a completed Direct Member Reimbursement (DMR) form and receipts to the claims address for your plan. CVS Caremark has historically routed paper claims to a P.O. box in Phoenix, AZ, but the exact box number can differ by plan and change over time — so pull the current address from your DMR form or the member portal. Attach the original pharmacy receipt showing the drug name, quantity, date of fill, and amount paid. Note that reimbursement claims have filing deadlines, often within 12 months of the date of service, though your plan may allow a shorter or longer window. Submit as soon as possible.
Appeals and Grievances
If a claim was denied and you want to file a formal written appeal, send it to the exact address specified in your denial letter. This is not a place to guess. CVS Caremark uses different appeals addresses depending on plan type (commercial, Medicare Part D, Medicaid), and Medicare Part D appeals in particular follow strict, CMS-regulated procedures and timelines. Your appeal should include your member ID, the prescription in question, the denial reference number, and a letter from your prescriber explaining medical necessity. For a walkthrough of the underlying process, see our article on what prior authorization means. If you no longer have the denial notice, call the number on your card to request a copy and confirm where to send the appeal.
When to Use Mail vs. Phone or Digital
In most cases, phone and digital channels are faster than mail. Here is a quick guide.
Use mail when:
- Your doctor provides a paper prescription that cannot be submitted electronically
- You need to file a reimbursement claim with supporting receipts
- You want to submit a formal written appeal or grievance for your records
- Your plan requires written notification for coordination of benefits
Use phone or digital when:
- You need to check drug coverage or copay information
- You want to order or refill a mail-order prescription (the online portal is faster)
- You need to report a problem with a shipment
- You want to update personal information like your address or phone number
The CVS Caremark member portal and app handle most routine transactions. For complex issues, calling the CVS Caremark customer service phone number is usually the most efficient route — and the fastest way to confirm a current mailing address.
Why CVS Caremark Has Multiple Addresses
CVS Caremark operates processing centers across the country, each handling different functions. Prescription fulfillment, claims processing, and appeals review happen at separate facilities with specialized staff and systems, and some are assigned by plan or employer group. This is standard for large PBMs — Express Scripts and OptumRx use a similar multi-location structure. The key is matching your correspondence to the correct, current address for your plan. Sending an appeal to the mail-order pharmacy, for example, will cause delays while the mail is internally rerouted — if it is rerouted at all.
Tips for Mailing to CVS Caremark
A few practical steps can prevent common problems.
Confirm the address first. Check your card, your plan documents, or caremark.com before you mail anything time-sensitive, and call to verify if you are unsure.
Use certified mail or a tracking number. For appeals, claims, and original prescriptions, proof of delivery protects you if the document is lost in transit.
Keep copies of everything. Before mailing, photocopy or scan all documents so you can resubmit immediately if needed.
Include your member ID on every page. Processing centers handle large volumes of mail; your member ID keeps all materials linked to your account.
Follow up. Call after a reasonable interval to confirm receipt, and resubmit promptly if they have no record of your mailing.
Frequently Asked Questions
What is the main CVS Caremark address?
There isn’t a single “main” address for member paperwork — CVS Caremark uses different addresses for mail-order prescriptions, claims, and appeals, and they vary by plan. The corporate headquarters is in Woonsocket, RI, but that is for corporate correspondence only. For member mail, confirm the correct address on your ID card, your plan materials, or caremark.com.
Can I email documents to CVS Caremark instead of mailing them?
Generally, CVS Caremark does not accept claims, prescriptions, or appeals by ordinary email. You can use the secure message feature on the member portal for general inquiries, but official submissions must go by mail or through the plan’s designated electronic channels. Check your plan for the accepted methods.
How long does it take CVS Caremark to process a mailed prescription?
Mailed prescriptions typically take longer than electronic ones — often around two weeks from receipt to delivery, depending on the plan and the medication. Electronic prescriptions sent by your doctor are usually processed faster. Check your plan materials for specific timeframes.
Where do I send a CVS Caremark Medicare Part D appeal?
Use the exact address listed in the denial notice you received. Medicare Part D appeals follow specific CMS-regulated procedures and deadlines. If you no longer have the denial letter, call the number on your Medicare Part D member card to request a copy and confirm the appeal address.
Is the CVS Caremark address the same as CVS Pharmacy?
No. CVS Caremark (the PBM) and CVS Pharmacy (the retail stores) operate out of different locations with different mailing addresses. Do not send PBM-related correspondence to a retail CVS store.
Get Your Mail to the Right Place
The right CVS Caremark address depends on what you are sending and which plan you have — and because these addresses change, the safest move is always to verify. Match your correspondence to the correct destination, confirm it on your card or the official site, include your member ID on everything, and use certified mail for anything important. Better yet, use digital and phone channels whenever possible; they are faster, more trackable, and always route to the correct place. For more context on how CVS Caremark fits into the broader pharmacy benefit landscape, visit our healthcare policy guide.
TL;DR: CVS Caremark uses different mailing addresses for mail-order prescriptions, reimbursement claims, and appeals, and the correct address varies by plan and changes over time. Do not rely on a P.O. box copied from a general web page. Confirm the current address on your member ID card, your plan documents, or the official caremark.com portal — and for appeals, use the exact address printed in your denial letter.
