Maryland Address Generator
Use this Maryland address generator when you need realistic-format test data for checkout forms, tax-engine tests, QA scripts, UI demos, or seed records. The generator pairs a real MD city with one of its real ZIP codes and a phone area code used in the state, then combines those fields with a synthetic street line.
Maryland sales-tax background
6% statewide base sales tax. Statewide sales and use tax is 6%; local sales taxes generally do not apply. This page is an address-format testing utility and not tax advice. If your application needs official tax calculation, use a tax engine or the state's current tax-agency documentation.
State and local income taxes apply.
Cities and ZIP codes in this dataset
The dataset keeps city, state, and ZIP internally consistent. ZIP examples are intentionally small so the static site stays fast and easy to audit.

Common use cases

- Form-validation tests for city, state, ZIP code, and phone-area-code combinations.
- Mock customer records, design prototypes, documentation screenshots, and seed data.
Important caveats
The street number and street name are synthetic. The output is not deliverable and is not meant to pass USPS, AVS, bank, telecom, government, or shipping verification. For why this happens, read the AVS and ZIP validation explainer.
