Can I send HM Forces mail free of charge?
Occasionally, parcels for HM Forces personnel on operational duty can be sent free of charge. However, this is usually for a short period like the lead-up to Christmas. When this service operates, it is only open to friends and relatives of Forces personnel who are sending personal items via a Post Office® branch and it can’t be used for business mailings.Back to top
Can I send mail to personnel serving in the armed forces of other countries?
HM Forces Mail services are only for HM Armed Forces personnel serving at BFPO addresses, but this also includes civilian contractors situated at a BFPO address. We don’t have any special postal arrangements with the armed forces of any other nation, so you will need to pay at our usual international rates.Back to top
