Sharing the buzzer without handing out your phone number
Buzzer access and a personal phone number do not have to be the same thing. If the lobby panel stores a number that belongs to the apartment, such as a BuzzMeBro number, each person is reached behind it and no individual’s number is programmed into the panel. Access can then be given or removed later without asking the building again or anybody changing their phone number.
Live with others? BuzzMeBro puts more than one of you on the buzzer. First month free. Start free
A subletter for the summer, a partner’s teenager, a housemate you have known for three weeks. Each of them may need to let a delivery in, and none of that requires your mobile number, or theirs, in the building’s panel.
What putting a personal number in the panel means
On a typical telephone entry panel, each resident entry holds one phone number, programmed by whoever manages the panel. Mircom’s TX3 guide notes that a visitor cannot see the number being dialled. DoorKing’s manual shows the stored number can be displayed with the panel’s master code.
- Removing it later takes another request to the building.
- It can outlive the arrangement, ringing somebody who has moved on.
- Whoever answers a buzz can press the door digit, so the number and the access are the same thing.
- You cannot change your mind on a Tuesday afternoon without the building.
That last one is the real cost. What fixing a stale entry involves.
Separating access from the number
If the panel holds a number that belongs to the apartment, that is the only number the building stores. Who is reachable behind it is a list the household controls, not a record the building keeps.
| Their number in the panel | Behind an apartment number | |
|---|---|---|
| Panel stores their personal number | Yes | No |
| To grant access | A request to the building | Add their phone |
| To remove access | Another request to the building | Remove their phone |
| Survives them leaving | Yes, until somebody asks | No |
The consent half
The reverse matters just as much. Nobody should point a building buzzer at somebody’s phone without asking them first, and nobody should be added quietly.
With BuzzMeBro, a person you add gets a text from the apartment number telling them their phone is now on the buzzer. Everyone else on the apartment gets a text naming who made the change and the last four digits of the phone added or removed. It is $9.99 a month for the apartment across up to 4 phones, and our privacy policy covers what we store. How adding somebody works.
Only a call from your own lobby panel can open the door, so a stranger dialling the apartment number cannot open anything. What the building has to change.
From our own door
- BuzzMeBro has run on our founder’s own Toronto apartment door since August 2026.
- Switching the panel to our number means the building updates one stored number for the unit and nothing else, and pointing it back at the old number undoes it the same day.
- We do not record calls, do not sell data, never use it to train AI, and delete it before any sale of the company.
Questions people ask
Can I keep my number out of the buzzer entirely?
With an apartment number on the panel, your personal number is not stored in the panel. Your phone still rings, because that is the point, and the call shows the apartment number, which you can save as a contact.
Can a subletter be added just for the summer?
Yes. Add them when they arrive and remove them when they go, with no request to property management at either end. Their lease arrangement with the landlord is a separate matter.
Will the others on the list see my number?
Whoever adds you types your number in, so they know it already. After that, the BuzzMeBro app shows each phone masked, with the area code and last four digits, and the change texts show only the last four digits.
Can somebody add my phone without asking me?
They should not, and BuzzMeBro’s terms forbid adding anyone who has not agreed. The added phone gets a text saying it is on the buzzer, and everybody already on the apartment is texted about the change, so nobody is added quietly.
What if the arrangement ends badly?
Remove the phone. The buzzer stops ringing it, the number on the lobby panel is untouched, and there is nothing to ask the building for. Keys and fobs are separate and go back through the building.
