Seven Delray Beach place-name ZIPs
Delray Beach spreads across more than one five-digit code. The rows below come from GeoNames' US postal-code export (CC BY 4.0, retrieved 2026-08-03), filtered to the place string Delray Beach in Florida: 33444, 33445, 33446, 33448, 33482, 33483 and 33484.
Delivery type and population figures below come from zip-codes.com's Delray Beach city page, which lists the same seven codes as five Standard and two P.O. Box assignments and shows a data-last-updated date of October 1, 2026 (zip-codes.com: Delray Beach, FL, read 2026-10-21). Its population column is a better guide to where people live than the size of a code on a map.
All seven GeoNames rows sit in Palm Beach County. That matches the county shown on the commercial table and on Palm Beach County's own ZIP boundary maps for the coastal strip that includes Delray Beach.

Street delivery vs PO Box codes
For a street address, use one of the five Standard codes. By listed population, 33445 and 33446 are the largest residential codes, followed by 33484, 33444 and 33483. Those numbers come from the zip-codes.com table above; they do not tell you which block sits in which code, so look the address up rather than guessing from a neighborhood name.
33448 and 33482 are P.O. Box codes with no residential population in that table. Use them only when the person you are writing to rents a box and gives you that ZIP. Putting a PO Box ZIP on a street address is a common reason mail returns or forms reject the entry.
Aliases such as West Delray Beach on 33446, 33448 and 33484, and Gulf Stream on 33483, are alternate place strings some directories attach to the same five-digit code. In the GeoNames extract used here, the primary place name for every row is still Delray Beach, and the county stays Palm Beach.
Rough orientation for street codes: 33483 hugs the barrier-island and Atlantic Avenue corridor (Gulf Stream alias); 33444 and 33445 cover denser central and near-downtown tracts; 33446 and 33484 stretch farther west toward the West Delray Beach alias area. Always confirm with USPS ZIP Code Lookup before you file a tax return, order a credit card, or print a shipping label.
Boynton Beach sits immediately north and uses its own place-name ZIP set. Addresses near the city-limit line are a common mix-up: a Boynton Beach mailing address can sit a few blocks from a Delray Beach one. If the city printed on the resident's mail says Boynton Beach, use that city's code from the sister guide rather than forcing a Delray Beach ZIP from this table.
Area codes and nearby cities
Delray Beach phone numbers use area code 561, which NANPA overlaid with 728 beginning March 10, 2023, according to DialWick's area-code dataset (compiled from the North American numbering plan list). A ZIP change does not change a phone number; the two systems draw their boundaries separately.
Just north of Delray Beach on this site is Boynton Beach ZIP codes, another Palm Beach County list built from the same GeoNames export. For the general difference between a US ZIP and other countries' postal codes, see postal code vs ZIP code.
