You received a check or payment notice with an address you’ve never seen before. The payee line reads “Pay to the order of” followed by an unfamiliar name, and the remittance address points to PO Box 55520, Portland, Oregon 97238.
Here’s what we found: The box exists. The company behind it doesn’t.
At least not publicly. PO Box 55520 operates within a postal range used exclusively for financial transactions, but no business claims ownership of this address in public records, corporate registries, or consumer databases. This isn’t unusual for payment processing centers, but it leaves people stuck with a piece of paper and no way to verify where their money goes.

Why Portland Handles Your Payments
Portland’s 97238 ZIP code processes millions of bill payments every month. Banks, debt collectors, utility companies, and government agencies route checks through this district because the postal service built infrastructure specifically for high-volume financial mail.
The address range covering boxes 55481 through 55536 includes box 55520. One box away, at 55457, sits Quick Collect Inc., a medical debt collection agency operating since 1985. This proximity matters because payment processors and collection agencies cluster together in these postal districts. When one address handles medical collections, neighboring boxes often serve similar functions.
Lockbox services work like this: A company hires a bank or third-party processor to receive payments on their behalf. The processor rents a PO box, opens incoming mail, scans checks, credits accounts, and deposits funds. Your payment goes to Portland, but the actual creditor might operate anywhere in the country.
What Anonymous Addresses Hide
Three types of businesses typically avoid publishing their payment addresses:
Debt buyers and collection agencies use generic addresses to prevent consumers from identifying them before opening mail. If you recognized the collector’s name on the envelope, you might not open it.
Bank bill payment services like CheckFree process transactions for thousands of companies through centralized facilities. The Portland address appears on your bank’s check, but the money ultimately reaches your electric company, credit card issuer, or mortgage lender.
Third-party billing companies handle payments for medical practices, legal firms, and small businesses that outsource their receivables. The billing company owns the PO box, not your actual service provider.
This system protects processors from mail theft and fraud, but it creates a verification problem for anyone holding a payment request.
How to Confirm This Address
Start with your existing records. Pull out bills, statements, and account correspondence from the past six months. Look for any mention of Portland payment addresses or account numbers that match what appears on your current payment request.
Call the company using a phone number from your original billing documents. Do not use contact information from the suspicious notice. Ask specifically: “Do you use PO Box 55520 in Portland for payments?” Most legitimate creditors will confirm their payment addresses immediately.
Check the account number on the payment slip. Scammers often leave this field blank or use obviously fake numbers. Your real account number should match what appears on previous bills.
Review your credit report at annualcreditreport.com. Legitimate debts show up there, including the creditor’s name and account balance. If nothing matches, the payment request deserves skepticism.
Contact your bank if the request came as a check. Banks maintain databases of common payees and can sometimes identify who processes payments through specific addresses.
Red Flags That Demand Attention
Certain warning signs indicate fraud rather than legitimate billing:
The payment demand arrived without prior notice. Real creditors send multiple communications before requesting payment to a new address.
The notice threatens legal action or claims “final warning” status for a debt you don’t recognize. Collection agencies must validate debts when consumers dispute them.
The amount requested doesn’t match any account you hold. Payment processors don’t guess at figures.
The notice arrived via unusual channels like text message or email when you normally receive paper bills. Scammers test multiple contact methods hoping one sticks.
No account number appears anywhere on the payment request. Every legitimate bill includes account identifiers.
Where This Leaves You
Payment processing through Portland postal boxes happens daily for millions of Americans. Most transactions are legitimate. The problem comes when the system’s anonymity collides with your need to verify an unexpected payment request.
If you cannot confirm PO Box 55520 connects to a creditor you actually owe, do not send money. Request written validation of the debt, including the original creditor’s name, account history, and explanation of the Portland address. Legitimate businesses provide this documentation without hesitation.
Report suspicious collection attempts to the Consumer Financial Protection Bureau at consumerfinance.gov. They track patterns and investigate fraudulent schemes.
The address exists. Your job is determining whether the payment request does too.
