If all the ones in a single room don't work, the frozen pipe is between the split from the main line.

If no faucets work, it's likely somewhere near where the main water pipe enters the house.Will my pipes freeze if I have a basement?
Pipes in an unheated basement are usually safe from freezing because basement temperatures rarely go below 40, even in the coldest of winters, and sometimes when the heat goes off. Pipes in uninsulated walls may freeze, particularly if they are nearer the outside cover of that wall than the inside cover.How long does it take for pipes to unfreeze?
Using ½” copper pipe with ½” fiberglass insulation, at an ambient temperature of 20°F, it took about 2-hours for the pipe to reach 32°. This is the point at which the water in the pipe begins to freeze. For the pipes to become completely frozen to such an extent that there is zero water flow takes quite a bit longer.Do propane lines freeze?
Propane tanks will freeze up when the ambient temperature drops below -44°F. This is because propane has a boiling point of -44°F. If the temperature is not greater than -45°F, your propane will not vaporize, and your tank will freeze.How do you keep your pipes from freezing without heat?
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe - even at a trickle - helps prevent pipes from freezing.
