Services at Grand River Post Office
Street parking. Here's what you can do at this location:
PO Box & Mail
- Accountable Mail Pickup
- Pick up items that require a signature: Certified Mail, Registered Mail, Collect on Delivery, insured packages, and Signature Confirmation items.
- Hold Mail Pickup
- Pick up mail that USPS has been holding while you were away. You can request a hold for up to 30 days through usps.com or at the counter.
- Package Pickup (Notice Left)
- Pick up a package that couldn't be delivered — the carrier left a slip at your door. Bring the notice and a valid ID.
- PO Box (Online Management)

Other Services

- Staff can help answer questions or direct you to the right resource for issues with mail delivery, address changes, or other USPS services.
- Federal Duck Stamps
- Purchase a Migratory Bird Hunting and Conservation Stamp — required for waterfowl hunting in addition to a state license. Proceeds fund wetland conservation.
