United states postal service customer service telephone number

We work with the following carriers to deliver items. If you have an issue with your delivery, you can contact the carrier directly.

Important: Some national carriers use regional carriers to deliver your package. When this happens, your tracking information may not be accurately reflected on the national carrier website.

We ship some exceptionally large or heavy items by a specialty carrier such as CEVA, Pilot, or XPO. We use Parcel Pool for standard deliveries to Alaska and Hawaii, and OnTrac for same-day deliveries to Seattle.

Delivery Instructions entered on your Amazon account are only visible to Amazon Drivers. If your package is being delivered by a different carrier, please contact them to provide those instructions.

How to Change Your Address With the Postal Service

To let the post office know you are going to change your address permanently or temporarily and want your mail forwarded to your new location, you have two options:

• Go to USPS.com/move to change your address online.
  • This is the fastest and easiest way, and you immediately get an email confirming the change.
  • There is a $1.10 charge to change your address online. You will need a credit or debit card and a valid email address. The $1.10 charge to your card is an identity verification fee to prevent fraud and make sure you're the one making the change.
  • Warning: You don't need to pay a separate company to change your address. Scammers may charge $40 or more to do what you can do for just $1.10 using the moving section of the official USPS.com website.
• Go to your local post office and request the Mover’s Guide packet.
  • Inside the packet is PS Form 3575. Fill out this change of address form and give it to a postal worker behind the counter. Or, drop it into the letter mail slot inside the post office.
  • You should receive a confirmation letter at your new address in five business days.

How to Change Your Address With Other Government Agencies

Other federal and state agencies to contact when changing your address include: 

• IRS for federal taxes
• Social Security
• Veterans benefits
• Immigration
• Drivers license and Vehicle Registration
• Voter Registration

Forward or Hold Your Mail

Are you making a temporary move or heading out of town? The U.S. Postal Service (USPS) can forward your mail to a new address or hold it at your local post office for a limited time.

Forward Your Mail

If your move is temporary, the USPS can forward your mail from your old address to a new one for 15 days to one year.

• To get started, fill out an official USPS change of address form. This covers questions about the type of move, the mail forwarding start and end date, and more.
• Learn about other mail forwarding options, including the premium forwarding service.

Hold Your Mail

If you'll be away for three to 30 days, USPS can hold your mail at your local post office until you return. You can typically request this service as early as 30 days in advance or as late as the day before you want the hold to start. 

• Begin by creating or signing in to your USPS account. You can check to see if hold mail service is available for your address and choose the dates for your hold mail request.
  • Note: USPS has added an extra one-time-only security measure for online hold mail requests. You'll need to verify your identity online through a mobile phone passcode. Or, you can request an identity verification passcode to be mailed to your address. If you're not able to complete the identity verification online, you can still place a hold on your mail by going to your local post office. 
• If you want your mail held for longer than 30 days, sign up for the USPS mail forwarding service.
