Browse recovery resource ZIP codes in Maryland
Explore five-digit ZIP codes published by treatment and housing sources. A ZIP code is a postal identifier, not proof of a facility’s physical location, service radius, current licensing, medical detox availability or an open bed.
Find a source-reported ZIP
Only the five-digit postal codes in published records appear. The Oxford House operator entries in this import do not contain ZIP codes and are therefore not represented in ZIP counts; they remain available through the state and city directories. Missing ZIP data does not mean no housing is available.

The detox count is a subset of 2024 SAMHSA treatment survey records, not a separate verified medical-detox category. Treatment counts include published 2024 SAMHSA survey, 2026 SAMHSA OTP and state treatment source entries where available; the state NTP subset is separately identified for transparency. Housing figures use only published ZIP-coded source records. Counts are source entries—not independently verified unique providers.
