To program a NOAA Weather Radio, you need two things: the channel of the nearest NOAA Weather Radio transmitter, and the six-digit SAME code for your county. Set the channel first, then enter the SAME code in the radio’s SAME or county menu. The radio will then sound its alarm only for alerts that cover your county, including winter storm watches and warnings and blizzard warnings. The exact buttons vary by model, so keep your manual to hand, but the steps below apply to almost every SAME receiver.
Doing this before the first winter storm of the season matters. A National Weather Service guide puts it bluntly: “Your radio will not alert properly if programmed incorrectly!”
What NOAA Weather Radio is
NOAA Weather Radio is a nationwide network of radio stations broadcasting weather information from the nearest National Weather Service office. It runs 24 hours a day, seven days a week, from more than 1,000 transmitters covering all 50 states, adjacent coastal waters, Puerto Rico, the US Virgin Islands and the US Pacific Territories, according to the National Weather Service’s NOAA Weather Radio page. It also carries non-weather emergency information as an all-hazards service, working with the FCC’s Emergency Alert System.
The broadcasts use seven VHF frequencies: 162.400, 162.425, 162.450, 162.475, 162.500, 162.525 and 162.550 MHz. An ordinary AM/FM radio cannot receive them. You need a weather radio, a scanner, or a multi-band radio with a weather band. Our guide to radio bands explains where these frequencies sit compared with AM and FM.
What a SAME code is
SAME stands for Specific Area Message Encoding. Each alert carries codes for the areas it covers, and a SAME radio compares those codes with the ones you have programmed. If there is a match, it sounds the alarm. If not, it stays quiet. As the NWS Wilmington, Ohio office puts it, SAME lets receivers “be programmed by the user to only alarm for weather and other emergency events in specific, desired counties.”
The code has six digits. The NWS describes the format as PSSCCC:
- P is a partition digit. Some large counties are split into parts for alerting. A zero means “all or unspecified portions” of the county, which is what most people should use.
- SS is the state number. North Carolina, for example, is 37, which is why NWS Newport/Morehead City shows its codes starting 037.
- CCC is the county number.
The partition rules are on the NWS SAME code page. If your local NWS office uses partial-county alerting, its website will list the right P digit for your part of the county.
Step 1: Find your transmitter and channel
Your local NWS office’s website lists the transmitters it runs, their frequencies and the counties each one serves. Coverage overlaps, so you may hear more than one. Pick the one that gives clear reception and that broadcasts warnings for your county.
The NWS office in Newport/Morehead City advises that listeners “should experiment with all the transmitters available, to see which will give you the best reception for your location”. The Melbourne, Florida office adds a caution in its programming guide: you can enter more than one county code, “but only those which the radio station covers”. A clear signal from a transmitter that does not serve your county is no use for alerts.
If reception is weak everywhere in the house, try the radio near a window or on an upper floor. Our article on why reception is bad and how to fix it covers the common causes.
Step 2: Find your county’s SAME code
The NWS publishes SAME codes for every county, organised by state, on its NOAA Weather Radio county coverage pages. Many local NWS office sites also list the codes for the counties they serve. Write the six digits down. If you want alerts for a neighbouring county as well, for example the one you drive through to work, note that code too.
Step 3: Enter the channel and codes
The Melbourne guide walks through a typical receiver. Your buttons may differ, but the sequence is usually similar:
- Make sure the radio is plugged in, switched on and fitted with fresh batteries.
- Open the menu and find the channel setting. Scroll through the channels until you hear the broadcast from your chosen transmitter, then confirm.
- Open the SAME setting. Choose Single for one county or Multiple for several.
- Enter the six digits of your code one at a time, then confirm.
- For extra counties, move to the next SAME slot and repeat. The Melbourne guide says that receiver accepts “up to about 25” codes.
Step 4: Choose which alerts sound the alarm
Some receivers let you choose which event types trigger the alarm and which only show a message; your manual will say whether yours does. For winter, make sure these codes are switched on. The list comes from the NWS event code table:
| Event | SAME code |
|---|---|
| Winter Storm Watch | WSA |
| Winter Storm Warning | WSW |
| Blizzard Warning | BZW |
| Snow Squall Warning | SQW |
The NWS notes that older receivers may display newer codes as “unknown”, but they still play the audio. If your radio is old and shows “unknown” during a winter event, listen to the broadcast itself.
Step 5: Confirm it works with the weekly test
The NWS normally tests the warning alarm every Wednesday between 11am and noon, according to the Newport/Morehead City office. The Melbourne office adds that tests are skipped in bad weather and suggests checking the radio between 11am and noon and between 6pm and 8pm on Wednesdays. Schedules can vary by office, so check yours. If your radio never registers the weekly test, recheck the channel and code.
Standby mode and the alarm tone
The NWS notes that many receivers can be set to a muted standby mode. In standby, the radio stays silent until an alert for your area arrives, then the warning alarm sounds. The NWS Wilmington office describes this as a 10-second, 1050 Hz tone that serves as an audible attention signal. Put the radio where you will hear it at night, such as a bedroom or hallway, and keep batteries in it so it still works when the power goes off.
Why a radio still matters when you have a phone
Phone apps and wireless alerts are useful, but a weather radio does not depend on a mobile network or a charged phone. It also needs no location tracking: you tell it your county once, and that is all. ajmm.org has a useful explainer on which app permissions to allow or deny if you are deciding how much location access to give weather apps.

Frequently Asked Questions
Where do I find my SAME code?
The National Weather Service lists SAME codes for every county by state on its NOAA Weather Radio pages. Your local NWS office website usually lists the codes for its area too.
What does the first digit of a SAME code mean?
It is the partition digit. Zero means the whole county, which is right for most people. Other values cover part of a county in places where the NWS uses partial-county alerting.
Can I program more than one county?
Yes. Most SAME receivers accept several codes. The NWS Melbourne guide’s example receiver accepts up to about 25. Only program counties that your chosen transmitter covers.
Which SAME codes cover winter storms?
Winter Storm Watch is WSA, Winter Storm Warning is WSW, Blizzard Warning is BZW, and Snow Squall Warning is SQW.
How do I know my weather radio is working?
Watch for the weekly test, normally on Wednesdays around late morning. If your radio does not register it, check the channel and county code.
