Letters & packages
How to send letters & packages
Domestic USPS/UPS/FedEx shipping usually works well; many missions prefer packages to the mission office, but ask whether to send to the missionary's apartment instead.
- Your missionary can email weekly on P-day (preparation day: their weekly day for errands, letters and rest); letters and packages are optional extras.
- Confirm the current mailing address with the mission office or the call packet before sending — offices move.
- Small, padded envelopes usually travel faster and cheaper than boxes; declare contents honestly and avoid restricted items.
