United States FAQs
Which ZIP code do I use for BAH?
Use your duty station ZIP code, not your home address. BAH is based on where you are stationed, not where you choose to live. If you live off-base 30 miles from your duty station, your BAH is still based on the duty station ZIP.
What if my ZIP code is not recognized?
Some rural ZIPs map to nearby Military Housing Areas. The DoD groups ZIPs into MHAs based on geographic proximity. If your exact ZIP is not listed, try the nearest city or military installation ZIP.
Can I get BAH for a different location?
Generally no. BAH is tied to your permanent duty station. Exceptions include TDY (temporary duty) over 30 days and some PCS (permanent change of station) situations where you may receive BAH for your old or new location during transition.
Do all ZIP codes in one city get the same BAH?
Usually yes. An entire metropolitan area typically falls within one MHA, so all ZIP codes in that area receive the same BAH rate. Some large metro areas near military bases may have slightly different MHA boundaries.
How accurate is a ZIP-based BAH estimate?
Very accurate for planning. The official DoD BAH calculator uses the same ZIP-to-MHA mapping. Minor differences may exist if the DoD has updated MHA boundaries more recently than this tool reflects.
