Receiving Mail

Do you need someone else to pick up your mail?

If you need someone that is not an authorized family member or dependent to collect your mail, you will need to come into the Post Office and complete a PS form 3801 request, this form must be completed as a hard copy.

If you are unable to physically visit our Post Office, you will need to get a special power of attorney explicitly for handling and managing mail.

Planning to be out of the area for more than 5 days?

If you are absent for 5 days or more, use this self-service worksheet to help us manage your mail while you are gone. Click the button above to download the Temporary Forward / Hold Form. 

  • Temporary Hold:
    We'll hold all your mail until you return. Nothing will be sent back until the hold expires. First Sergeants may place a member's box on hold if the member is unable to.

  • Temporary Forward:
    We’ll send all your mail to another location until you return. You may selectively forward mail or parcels as well.

If you’ll be gone for more than 6 months, we require a copy of your orders. If you need your hold or forward extended, please send an encrypted email to the Customer Service org box.

Do you need to request or update mail service?

Our RAFM Post Office Worksheet will enable you to:

  • In & Out Process:
    Please complete the Mail Worksheet (see link above) 45 days in advance for in-processing and 90 Days for out-processing with a copy of your orders.
    *In and out-processing times are Monday through Friday, 0900 – 1030 and 1500-1600.

  • Request General Delivery Service:

  • Marriage, Birth, Change of Name:
    Add or update personal and dependent information with the Mail Worksheet and send it in with a copy of your supporting documents.
