Purchase the owner's telephone number from the property.

In some cases, the property may refuse to provide the owner's phone number. This is because the telephone number of the owner belongs to private information, and according to relevant laws and regulations, the property needs to protect the privacy of the owner.

Generally speaking, if the downstairs owners need to contact the upstairs owners to communicate, they should inform them through the property, and the property will contact the upstairs owners to coordinate and solve the problem. In this case, the property can refuse to provide the telephone number of the upstairs owner, but it needs to ensure that the information can be transmitted to the upstairs owner.

Under special circumstances, such as the reserved telephone cannot be connected, if it is necessary to contact by force, the public security organ must be present and record on the spot before entering by force.

In short, in any case, the property has the right to protect the privacy of the owner, so when asking for the owner's phone number, we should respect the position of the property and follow the relevant laws and regulations.
