Cameron Post Office & mailbox keys
Cameron Post Office
202 W. 2nd Street, Cameron, TX 76520 — not the DQ on W. 4th Street.
Start here to ask about residential mailbox assignment and keys. Contact the Post Office first to confirm that it serves your address, whether delivery is established, who owns the cluster mailbox, and what identification or proof of occupancy it needs you to bring.
- USPS-owned boxes: the local Post Office handles compartment keys and lock changes. USPS says a new resident is not charged for the first lock and keys; lost-key replacements can involve local charges.
- Privately owned boxes: the developer, HOA or property owner supplies locks and keys. USPS delivering to a box does not mean USPS owns it.
We have not independently confirmed who owns Highland Branch’s mailbox units. This is guidance for residential cluster mailboxes, not renting a PO Box. A validated mailing address or ZIP code alone does not establish active mail delivery.
