Enso Village has three street addresses, which are determined by the city and fire department.
For US Postal Service purposes, you should use your building address plus your unit number from the table below. If you provide your correspondent with the five-digit ZIP code 95448 (Healdsburg) and the street address plus unit, that will do the trick. All mail ends up in the boxes in the mail room, not at an individual unit.
The USPS provides an online ZIP code lookup you can use as a reference. The reference page gives a ZIP+4 result which can be used if you prefer. It is not required. Mail that is pre-sorted or computer scanned often has ZIP+4 bar-codes added.
As of January 31, 2024 the lookup page lists these addresses and unit numbers:
1789 Boxheart Drive:
Units 1001 – 2010;
1795 Boxheart Drive:
Units 101 – 145 // 201 – 245 // 318 – 345 // 418 – 445;
1801 Boxheart Drive:
Units 146 – 175 // 246 – 283 // 346 – 374 // 455 – 474;
Other carriers (e.g. UPS or FedEx) should also be able to handle street address plus unit number, and will deliver to the package room.
