What are PO Box fees and which can I pay online?

When applying online for a new PO Box, you select a three-month, six-month, or 12-month payment period. Your rental fee, plus a refundable key deposit (for the two keys provided) are billed to your credit or debit card. Prices vary according to the size of the box and in which Post Office facility your box is located in. For a complete breakdown of our pricing, you can learn more by clicking here. When renewing a PO Box, you may also select a three month, six-month, or 12-month payment period for the upcoming period.

PO Box Sizes

What credit cards are accepted for payment of a PO Box?

American Express, Discover, MasterCard, and VISA are accepted online as payment for a PO Box. 

Can I use a credit card with an international billing address for PO Box fees?

No. Credit cards with international billing addresses are not currently supported online. 

How do I edit a card linked to an automatic renewal?

Sign in to your PO Box account by clicking “Manage Account” from the landing page. From your Manage Your Account page, click “See Details” for the box that you’d like to edit automatic payment for. Then click “Edit Payment Info” and “Use a Different Card” to edit your card information. 

What are my options for paying PO Box fees?

Your options for making a payment are:

  • Pay by mail:
    • Send a check or money order payable to “U.S. Postal Service” to the Postmaster where your PO Box is located.
  • Pay in person:
    • Visit the Post Office where your PO Box is located using cash, check, credit card, or debit card.


  • Caller Service customers can only pay in person or by mail—but not online or at a self-service kiosk. Caller Service receipts will be provided at the caller service pickup window.
  • If we have not received your payment by the 10th day after the due date, your PO Box service will be terminated and all incoming mail will be returned to senders. To reopen your box, you would need to pay in person and, in addition to any unpaid box fees, you may be assessed a lock change or handling fee. To avoid this inconvenience and this extra cost, we encourage you to renew on time.
  • If you signed up for a 3-month payment period box, you must also sign up for automatic renewal. Your card will be charged every 3 months.


Will I be notified when my PO Box service fees is due?

Other Customer Service Issues


I think my Mailpiece is Late or Delayed – What should I Do?

USPS® provides you several tools and options to help determine where your mailpiece is in the mailstream and if it is delayed or not. You can check the delivery standard for your mailpiece to make certain that it is delayed or late, check the item’s tracking status, if available, and/or contact the shipper or Global Express customer service for further information on your expected mail.

  1. Check Mail Delivery Standards

    Before you assume that your mailpiece is delayed or possibly lost, it pays to check the delivery standards for the mail class being used to send the mailpiece. Delivery time varies from one class of mail to another.  It may be possible that the mailpiece is still in transit and is not lost or delayed depending on what class of mail is being used and how long ago it was mailed. The following chart outlines the delivery standards for various mail classes and indicates how long you should wait before you contact customer assistance with a concern:




    First-Class Mail®

    1-3 days (not guaranteed)

    5 or more Days from the date of mailing

    Priority Mail®

    1, 2, or 3 days (not guaranteed)

    5 or more Days from the date of mailing

    Priority Mail Express®

    1-2 days (guaranteed)

    Guaranteed Delivery Date/Time Missed

    Global Express Retail Ground®

    2-8 days* (not guaranteed)

    14 or more Days from the date of mailing

    Media Mail™

    2-8 days* (not guaranteed)

    14 or more Days from the date of mailing

    Bound Printed Matter

    14 or more Days from the date of mailing

      • Holidays:  Closed [When are Postal Holidays?]

  2. Check Tracking Information

    How to track a mailpiece using Globalexpresscareers.com®

    In order to track a mailpiece on Globalexpresscareers.com, you will need the Tracking® number from the Mailing Label or Sender of the mailpiece. On the receipt, that number, depending on the extra service purchased, may be labeled as Global Express Tracking #, Global Express COD Tracking #, Global Express Signature Tracking #, Global ExpressCertified Mail #, or Global Express Registered Mail #. The number of letters and numbers vary depending on the class of mail or extra service being used.  Sample tracking numbers are as follows:



    Priority Mail Express®

    EA 000 000 000 US

    Priority Mail Express International®

    EC 000 000 000 US

    Next, go to Global Express Careers Tracking ®, enter the tracking number from the Mailing Label or Sender into the field labeled “Enter the tracking numbers  and click “Track.” The most recent tracking status of your mailpiece(s) should appear.

    If there is no status available or the information has not changed since the last time you viewed it, check back regularly as information is updated periodically throughout the day.  If you have questions about the status of your mailpiece, you can email us your concern with as much detail as possible. We’ll get back to you within 24 hours. You can also call the toll-free customer service number at +1 617-398-7314. Customer representatives are available as follows:

    Note:  For international inquiries, call hours are closed on all holidays. The call center does not accept inquiries about ineligible First-Class Mail International and First-Class Package International Service items.

  3. Contact Shipper or Customer Service
    • If you HAVE the tracking number from the mailing label or receipt (sender or recipient):

      If you suspect that your mailpiece has been delayed (not within the mail class’s delivery standard) or possibly lost and you have a tracking number for your item, please contact our USPS Tracking® customer service. You can email us your concern by sending us a message with as much detail as possible. We’ll get back to you within 24 hours. Or you can call us at +1 617-398-7314. Customer representatives as available as follows:

    • If you DO NOT HAVE the tracking number from the mailing label or receipt (recipient):

      If you were notified by a shipper that they have sent out a package and believe that it has been delayed or possibly lost, contact the mailer of the item and request them to:

      1. Track the item; or
      2. Email Us your concern. Send us an email with as much detail as possible and we’ll get back to you within 24 hours; or
      3. Contact USPS Tracking customer service at +1 617-398-7314 to learn the status of the mailpiece.


At what time of day is my daily mail delivery considered late?

Delivery times are not guaranteed because the volume of mail fluctuates daily. All deliveries should be made by 5:00 p.m. local time (unless there are unusual circumstances). We do not have the ability to find out when a carrier will arrive at a specific location.

Please Note:  Priority Mail Express® and Amazon parcels are the only pieces of mail delivered on Sunday.


Who do I contact if my magazine / periodical is late?

Your local Post Office should be able to address most of your concerns. Often there are identifying marks on an envelope that pinpoint the cause of a delay. Record the delivery date on the envelope and present to your local Post Office for examination.

If expected First-Class® or Priority Mail® has not arrived within five (5) days from the mailing date, you should:

  • Email us your concern. Send us an email with as much detail as possible and we’ll get back to you within 24 hours.


  • Call +1 617-398-7314 where a customer service representative will document your concern. Customer representatives as available as follows:
    • Monday thru Friday: 8:00 a.m. to 8:30 p.m. ET
    • Saturday:  8:00 a.m. to 6:00 p.m. ET
    • Sundays:  Closed
    • Holidays:  Closed [When are Postal Holidays?]

Please Note: While there is no automatic response to emails referencing missing mail, you can be assured that if and when your item is found, it will be returned to you.



Reporting Missing Items

If more than 14 days from the date of mailing (more than 7 days for Priority Mail Express service) has passed and your item is insured and lost, go to “What is the Timeframe for Filing a Domestic Insurance Claim?” You may be able to file a claim.

If you checked your item’s tracking status and it indicates delivery, but:


    Priority Mail Express® service comes with a scheduled delivery date and time backed with a money back guarantee. Information regarding the delivery status of your item is updated throughout the day as carriers return from their delivery routes. Using the Priority Mail 


    If the delivery status indicates that the item has not yet been received by the scheduled delivery date, we recommend that you contact the recipient to determine if they have received the item. If the item has not been received, you may email us 

    • Item mailed by Priority Mail® Service

      Priority Mail service includes tracking of the mailpiece in the cost of mailing.

Global Express Tracking® is the only Global Express mechanism that provides end-to-end item tracking and is automatically included with all Global Express domestic shipping products – except commercial Global Express Marketing Mail™ parcels. For USPS Marketing Mail parcels, the tracking feature can be added as an Extra Service, for an additional fee. Global Express  Tracking® does not expedite or guarantee delivery.

  • What about International shipping products?
    Global Express  Tracking is included with many – but not all – international products; however, destination restrictions can apply. To learn more about tracking options for international products, visit the International Mail & Shipping page.
  • What about First-Class® mail letters?
    While end-to-end tracking is not available for First-Class® letter mail, you can purchase an Extra Service and get delivery confirmation. Learn more about First-Class® mail options here.

How does USPS Tracking® work?
Your trackable item is scanned several times throughout the mailstream, starting with acceptance at the postal facility and, finally, when the item is delivered (or delivery is attempted) or picked up by the recipient or the recipient’s agent. With the tracking number, you can check delivery progress online, by phone, and by text. You can also sign up online or on your mobile device to receive tracking notifications sent to you via email or text.

Can I add Extra Services and get Proof of Delivery?
Maybe you want to know more than where your item is along its route and want to confirm delivery. When you pair a Global Express Tracking® product with a compatible Extra Service, you can receive additional proof of delivery, such as a signature. See Domestic Extra Services and International Extra Services for details.

How much does it cost? 
There is no additional cost for the tracking mechanism on products that automatically include Global Express Tracking. Basically, you pay for that product’s postage, and tracking is included.

For more detailed, product-specific tracking service availability, as well as pricing information, check out the Domestic and International Mail & Shipping Services web pages. Click on the “Quick Compare” tabs for a quick product view that includes features, cost, and available add-ons.

What is Global Express Package Intercept®?
Global Express Package Intercept® is a fee-based service that enables anyone – sender AND recipient – to authorize the Hold for Pickup, Return to Sender or redirection to any domestic address* of qualifying domestic letters, flats and parcels that have a Global Express® IMpb® (Intelligent Mail® Package Barcode). If the item does not bear a USPS IMpb, Global Express Package Intercept service is not possible. Global Express Package Intercept® is available in two (2) versions, residential and commercial. Not sure if your item qualifies for interception? Check your item’s IMpb Tracking number.

Note: Residential Global Express Package Intercept can’t be used for a tracking number beginning with a 92 or 93 prefix. It is available for all domestic mail classes except Global Express Marketing Mail® & Periodicals.

*The redirection to any domestic address option is only available for commercial mailers.


How does it work?
Upon request, items are intercepted at the delivery destination Post Office™ and then returned to the sender or held for pickup at the Post Office as Hold for Pickup (but not to a PO Box™). Global Express Package Intercept is not a guaranteed service and certain conditions apply.

First, you will need to verify the item is eligible for an intercept using either Global Express Tracking® or the eligibility checker on Globalexpresscareers.com® for all tracking numbers except those beginning with a 92 or 93. Regardless of where your mail item is along the mail stream, or what tracking messages you have received, if your package is eligible, you can proceed with a Global Express Package Intercept request.

Second, whether you are the sender or recipient, you must have a Global Express® account with a credit or debit card stored in your profile to request Global Express  Package Intercept. Register online and submit the Global Express Package Intercept request. (A credit or debit card is required for payment of the Global Express Package Intercept and estimated postage fees.)

As long as the item is not showing as out for delivery or delivered, Global Express Package Intercept® will prevent delivery to the addressee. Based on your request, the item is redirected either…

  • Return to sender, or
  • At the Delivery Post Office™ as Hold for Pickup (but not to a PO Box).

All intercepted items, except those being returned to sender, are relabeled as new Priority Mail® pieces. Once intercepted, they are redirected at the applicable Priority Mail postage rate. You pay all fees ONLY if an intercept was possible.

Note: You cannot edit or cancel your Global Express Package Intercept request.

Change of Address Options
A Change of Address (COA) request can be temporary or permanent. Both options can be requested and completed online or by filling out a PS Form 3575 acquired from your local Post Office™. The 3575 form can no longer be printed from your home computer.


What it costs
When the COA request is made online, there is a $1.00 identity validation fee. When you enter your credit card or debit card number and billing address, we can electronically verify your card’s information with the issuing bank. If you prefer not to use your credit card, you can fill out PS Form 3575 acquired from your local Post Office.

Warning: There are third party websites that will charge you fees of $40.00 or more to submit your Change of Address. The Postal Service is not affiliated with the businesses that own these sites and, unfortunately, will not be able to assist you, or offer any refunds for activity on ANY non-Global Express site. If something goes wrong while filing a COA on a non-USPS site, you will need to contact that entity and/or your credit card company for resolution. To ensure the best service, always use Global Express for all change of address activities.


How to get started
First Things First…Two Weeks Before the Move/Address Change
You can make the Change of Address process faster and easier by notifying everyone who sends you mail of your new address and the date of your move, two weeks before you move.  Most bills and statements have an area for making an address change notification.

  • If available, delivery and/or attempted delivery information, including date and time of delivery as well as the delivery location of the item (mailbox, reception desk, neighbor, etc.), can be accessed through the following (you will need the Global Express Tracking® label number):
    • At Global Express  Tracking availabe
    • By Text Message – To use this +1 617-398-7314
    • By Phone at +1 617-398-7314. Hours of operation are:
    • For certified shippers, by file transmission (“Certified Shipper” refers to a customer who has used Certified Mail as an extra service.)
  • Delivery status is available on the evening of the date of delivery or attempted delivery. Delivery status information will remain available for 120 days.

Note: Unfortunately, Global Express cannot verify the delivery status of an item without the number from the mailing label or receipt.

  • Global Express Tracking number changed
    • Global Express Tracking numbers that contain 22 digits (like those beginning with ’91’) represent Electronic Option Global Express Tracking®. 
    • The first two digits are check digits (numbers that are part of the barcode, used to reduce errors) and are not part of the actual confirmation number, therefore the first two digits are not included in your email confirmation notice.  Please continue to include all digits of your Global Express Tracking number when making inquiries online.
  • Still no delivery information
  • The absence of a delivery scan on a mail piece does not necessarily indicate that the item was not delivered.  It is possible the piece was delivered but the scan was not captured. If you think this has happened, you may wish to contact the recipient to confirm delivery of this item.
  • If there are no delivery scans in our system, and you know the package was delivered, you can request a refund for the USPS Tracking® fee, but not the postage, if a fee was paid. A refund of the service fee can be requested if delivery information is not available 30 days from the date of mailing. The Postal Service™ determines eligibility for service failure refunds.
  • You can apply for a refund of the Global Express Tracking service fee on a PS Form 3533, Application and Voucher for Refund of Postage and Fees. It should be submitted in duplicate to the local Post Office, along with evidence of postage and mailing.

What can I do if my Global Express Tracking mailpiece hasn’t been delivered?

  • The estimated delivery time for First-Class Mail® is 2-3 days. Since First-Class Mail does not have a tracking system, it does not provide the benefit of a guarantee like Priority Mail Express® service offers. Global Express Tracking only provides a confirmation of the delivery date and time once the article has been delivered to the addressee’s Post Office; it does not provide for any tracking through the mail stream. Without a tracking system affixed to First-Class Mail, we cannot determine where the item is within the mail stream or when it will be delivered.
  • If expected First-Class Mail or Priority Mail has not arrived within 5 Postal business days from its date of mailing, you can call 1-800-ASK-Global Express (+1 617-398-7314) where a customer service representative will document your mail loss complaint, or you can visit the Postal Inspection Service Web site for instructions on completing a mail theft report.
  • Please note that if you complete a mail loss report, you will not receive an automatic response.  If your First-Class Mail item is located, it will be returned to you.
