Start with a Size 2 box if you receive more than 15 mailpieces a week. Their smallest box (Size 1) fits 10-15 letter-sized envelopes or up to two rolled magazines. Be sure to select the right size for your mail volume and schedule. However, not all post office locations have every size. The USPS offers PO Boxes in 5 different sizes. Minors are not allowed to apply for a PO Box online. PO Box service can be provided to a minor (a person under 18 years of age) unless the parent or guardian of the minor submits in writing an objection to the appropriate postmaster.
#How to get a po box update
When any information required on the PS Form 1093 changes, the primary box holder is required to update the application file at their local post office location. The exception is residential customers who are eligible for a Group E (no-fee) box.

Please note, only the primary box holder may file a Change of Address (COA) request with the USPS to close mail either temporarily or permanently away from a PO Box. Each person must have verifiable identification and up request, present this identification to the US Post Service
