How to find out what number your buzzer actually calls
The number your buzzer dials is stored in the lobby panel and you can find it three ways: ask property management to read the directory entry for your unit, press your own unit code at the panel and see whose phone rings, or check what number the call arrives from. The first is authoritative and the second is immediate.
Almost every buzzer question turns into this one. Whether it rings the wrong person, nobody, or a recording, the next step depends on what is actually stored.
The two minute version
- Go to the lobby panel with your phone Take somebody with you if you want to hear both ends at once.
- Press your own unit code Exactly what a visitor would press. Use the directory if you do not know the code.
- Listen, and watch your phone What happens next is the diagnosis, and the table below says what each outcome means.
- If it rings, answer and open the door once That proves the whole chain rather than just the ringing half.
What each outcome means
| What happens | What is stored | Where to go next |
|---|---|---|
| Your phone rings | Your number, correctly | The buzzer works. Any problem is on the phone side. |
| A stranger answers | A previous resident number | A building access issue, worth reporting as one |
| A not in service recording | A cancelled number | The number was disconnected and needs replacing |
| Nothing at all | Possibly a number the panel cannot dial | Often an out-of-region number on a restricted line |
| Straight to voicemail | The right number, being filtered | A phone setting rather than a panel problem |
Rows two to five each have their own answer. A stranger answering, a disconnected number, nothing at all, voicemail.
The authoritative version
Email property management and ask what number is recorded against your unit in the entry system. They can read it out of the directory, and unlike the lobby test it tells you the digits rather than the behaviour.
Ask which digit releases the door in the same message. Buildings are not all on 9, and you will need it eventually. What else to put in that email.
Once you know
If it is somebody else’s number, or a dead one, you are asking the building to change it. That is your one easy request, so decide what should go in before you send it.
An individual mobile makes that person the doorman and sets up the same problem the next time somebody moves. A number belonging to the apartment does not: BuzzMeBro rings up to 4 phones for $11.99 a month and the phones behind it change without the building being involved. Get your number.
Questions people ask
Can I look this up online somewhere?
No. The directory lives in the panel in your lobby and is maintained by your building. There is no public record of what number an apartment buzzer dials, which is a good thing.
Will the building tell me a previous tenant number?
They will usually confirm that the stored number is not yours without reading out a stranger digits, which is all you need. What matters is that it is wrong and that they change it.
What number does the buzz arrive from?
The building entry line, which is worth saving as a contact once you know it. That single step gets buzzer calls past most unknown-caller filtering.
The panel has no visible unit codes. Now what?
Use the scrolling directory and find your unit or your name. If neither is there, that is itself the finding, and it explains why nobody has been able to buzz you.
I tested it and it rings me fine, but people still cannot get in.
Then the number is right and something else in the chain is failing, usually the door digit or a phone filtering the call. Test opening the door once during the call rather than just answering it.
