How to Pay Your USPS Bill or Postage Online and by Mail

Published on October 29, 20267 minute read

How USPS Payment Works

The U.S. Postal Service does not send monthly bills to most people. Instead, you pay for postage or services at the time you use them—when you buy stamps, mail a package, or rent a mailbox. If you have a business account or a postage meter, you may receive an invoice and have payment options. For residential customers, payment happens at the counter, through the USPS website, or through an authorized retailer.

If you owe USPS money—for example, because a package was returned and you need to pay postage due, or because you have a business account with an outstanding balance—you can pay online through your USPS account, by phone, by mail, or in person at a Post Office location.

Key Takeaways

Most USPS payments happen when you buy stamps or mail packages, not through a monthly bill.
Business account holders and postage meter users receive invoices and can pay online, by phone, or by check.
You can set up automatic payments (called Informed Delivery or account autopay) if you have a USPS business account.
Postage due on returned packages can be paid at the Post Office, online if you have an account, or by check sent to the address on the notice.
USPS does not accept credit card payments by phone for security reasons, but online payment through USPS.com accepts most cards.

Paying for Stamps and Postage Online

The easiest way to buy postage without leaving home is through USPS.com. You can purchase stamps, print shipping labels, and pay for Priority Mail, Priority Mail Express, and other services. Payment is made at checkout using a debit card, credit card, or bank account.

If you have a USPS account (free to create), you can save your payment method and shipping addresses. This speeds up future purchases. You can also use Click-N-Ship, USPS's online shipping tool, to print labels and pay for postage from home. The label prints immediately, and you can drop the package at any Post Office or in a collection box.

For residential customers who want to buy stamps only, you can also order them through USPS.com and have them delivered to your home. A small delivery fee applies.

Paying a USPS Business Account Invoice

If you have a USPS business account (for a mailbox rental, meter account, or commercial shipping), you will receive an invoice by mail or email. The invoice shows what you owe and when payment is due.

To pay a business account invoice, you have several options:

Online through your USPS account: Log in at USPS.com, go to your account settings, and look for the billing or payment section. You can pay with a debit card or credit card.
By phone: Call the USPS Business Customer Service line at 1-800-222-1811. They can take payment over the phone using a bank account (ACH). USPS does not accept credit or debit cards by phone.
By check or money order: Mail payment to the address shown on your invoice. Include your account number on the check.
Automatic payments: Set up recurring payments through your USPS account so you do not have to pay each month manually.

Payment is usually due within 30 days of the invoice date. If you pay late, USPS may suspend your account or add a late fee, depending on your account type.

Paying Postage Due on Returned Mail

If a package or letter is returned to the sender because the address was wrong or the recipient refused it, USPS may charge postage due. You will receive a notice in the mail asking you to pay the amount owed before the item is delivered or returned to you.

You can pay postage due in three ways:

In person at the Post Office: Bring the notice and pay with cash, check, debit card, or credit card.
By mail: Send a check or money order to the address on the notice.
Online (if you have a USPS account): Log in and look for pending postage due charges. Some accounts allow you to pay directly; others require you to contact the Post Office.

If you do not pay within the timeframe shown on the notice (usually 15 to 30 days), the item will be returned to the sender or destroyed.

Setting Up Automatic Payments for a Postage Meter or Mailbox Rental

If you use a USPS postage meter or rent a mailbox, you can set up automatic payments so your account stays active without manual payment each month. This is done through your USPS business account online.

To set up autopay, log in to USPS.com, find your account settings, and look for the payment or billing section. You will need to provide a bank account (for ACH withdrawal) or a debit card. Once set up, USPS will charge your account on the due date each month. You can change or cancel autopay at any time.

Automatic payments reduce the risk of late fees and account suspension. If your account balance drops below a certain amount (which varies by account type), USPS may automatically charge your payment method to replenish it.

What Happens If You Miss a USPS Payment

The consequences of a missed USPS payment depend on your account type. For a business account or postage meter, a late payment can result in:

A late fee (amount varies by account type)
Suspension of your account, preventing you from using your meter or mailbox
Loss of any discounts you receive on postage rates
Collection action if the debt remains unpaid for several months

If your account is suspended, contact USPS Business Customer Service at 1-800-222-1811 to bring your account current and request reinstatement. Payment must be made before your account can be reactivated.

For postage due on returned mail, if you do not pay within the notice period, the item will not be delivered and may be returned to the sender at no additional cost to you.

Paying USPS Fees and Services by Mail

If you prefer to pay by mail, send a check or money order to the address on your invoice or notice. Always include your account number, invoice number, or the reference number from your postage due notice so USPS can match the payment to your account.

Mail payments take 7 to 10 business days to process after USPS receives them. During this time, your account may still show as past due. If you need immediate payment confirmation, pay online or in person instead.

Do not send cash by mail. Use a check, money order, or pay online to protect yourself.

Frequently Asked Questions

Can I pay a USPS bill with a credit card over the phone?

How long does it take for an online USPS payment to go through?

Online payments through USPS.com are usually processed immediately. Your account should reflect the payment within a few minutes. If you pay by bank account (ACH) by phone, it may take one to three business days to clear.

What if I do not have a USPS account but need to pay postage due?

You can pay postage due in person at any Post Office location with cash, check, debit card, or credit card. You can also mail a check to the address on the postage due notice. You do not need a USPS account to pay postage due.

Contact USPS Customer Service at 1-800-275-8777 (residential) or 1-800-222-1811 (business) with your account number or invoice number. They can review the charges and explain what you owe. If you believe there is an error, ask for a detailed breakdown of the charges.
