You just pulled a letter from your mailbox. The return address says PO Box 10 Anaheim CA 92815. You have never seen it before, and now you are wondering if it is real.
You are not alone. Thousands of people across the U.S. search for this exact address every month. Most of them are confused, concerned, or just curious. In this guide, you will learn exactly who uses this PO Box, why you received mail from it, and what steps to take next.
Let’s break it all down.
What Is PO Box 10 Anaheim CA 92815?
First things first. PO Box 10 Anaheim CA 92815 is a real, registered post office box. It is located at the Federal Anaheim post office in Orange County, California. The full zip code is sometimes written as 92815-0010.
A PO Box is simply a rented mailbox inside a post office. Businesses and organizations use them to receive and send official mail. So, this address belongs to a real entity, not some random or fake source.
However, the tricky part is that PO Boxes do not show a company name right away. That is why so many people feel unsure when they see unfamiliar mail from this address.

Now that you know the address is real, the next question is obvious. Who actually sends mail from PO Box 10 Anaheim CA 92815?

Providence and St. Joseph Network Support Services
The primary organization linked to this address is Providence Health. More specifically, it is used by St. Joseph Network Support Services for claims billing and administrative purposes.
If you have ever visited a doctor, hospital, or clinic within the Providence health system, this is likely the source of your letter. Providence operates a large network of medical groups and hospitals across California and several other states.
They use this PO Box as a centralized mailing address for billing-related correspondence. In other words, it is their claims processing hub.
Canopy Health and Other Healthcare Networks
Besides Providence, other healthcare networks also reference this address. For example, Canopy Health has listed PO Box 10 Anaheim CA 92815 in their provider manuals for billing correspondence.
So, if you are enrolled in a health plan connected to these networks, that could explain the letter as well.
Why Did You Receive Mail From PO Box 10 Anaheim CA 92815?
There are a few common reasons you might find this address on your mail. Here are the most likely ones.
- Medical bill. You may owe a balance from a recent doctor visit, lab test, or hospital stay.
- Insurance claim update. Your insurance provider processed a claim, and the notice came through this address.
- Explanation of Benefits (EOB). This is a summary of what your insurance covered and what you may still owe.
- Billing adjustment or correction. Sometimes billing departments send updated statements.
In most cases, the letter is tied to a healthcare visit you had in the past. Even if it was months ago, medical billing often takes time to process. That delay catches a lot of people off guard.
From personal experience, I once received a medical bill nearly five months after a routine checkup. It came from an address I did not recognize, and I almost tossed it out. Thankfully, I verified it first. The bill turned out to be completely legitimate.

Is PO Box 10 Anaheim CA 92815 Legitimate or a Scam?
This is the big question. And it is a fair one to ask. Let’s look at both sides.
Signs It Is Legitimate
Your letter is most likely real if any of these apply.
- It mentions a doctor visit, hospital stay, or lab test you actually had.
- The organization name matches a known healthcare provider like Providence.
- The contact information on the letter matches details on the provider’s official website.
- It includes your correct name, date of birth, or patient ID.
If you can connect the dots to a real medical event, the letter is probably authentic.
Red Flags to Watch For
On the other hand, be cautious if you notice these warning signs.
- You have no history with any medical provider in California or the Providence network.
- The letter asks for your Social Security number, bank account details, or credit card info through the mail.
- The tone feels overly urgent, threatening, or pressuring you to act immediately.
- The letter contains spelling errors or looks unprofessional.
Scammers sometimes use legitimate-looking addresses to trick people. So, always verify before you respond or send any money.
What Should You Do If You Get Mail From This Address?
If a letter from PO Box 10 Anaheim CA 92815 lands in your mailbox, follow these simple steps.
- Stay calm. Do not panic or rush into any action.
- Read the letter carefully. Note the organization name, account number, and any reference details.
- Verify the sender independently. Do not call the phone number on the letter right away. Instead, look up the organization online and use their official contact info.
- Check your patient portal. If you have a Providence or St. Joseph account, log in and look for any outstanding balances or recent claims.
- Call the official billing line. For Providence, call 866-747-2455. For St. Joseph Heritage Medical Group, call 855-221-8046.
- Report suspicious mail. If you believe the letter is fraudulent, report it to the Federal Trade Commission (FTC) at ReportFraud.ftc.gov.
This quick checklist can save you from both unpaid bills and potential scams.

If your letter turns out to be a real medical bill, here is how to handle the payment.
- Use the address on your statement. Always mail payments to the address printed on your specific billing statement. It may differ from the return address on the envelope.
- Pay online. Providence offers a secure online bill pay portal at Providence.org. You can view your balance, make a payment, or set up a plan.
