How Do I Find Out My Landline Number?
To determine a landline number, contact the customer service department of the landline service provider or review the most recent landline phone bill. If this information is unavailable, call a phone with caller ID to reveal the landline number.
Landlines work by transmitting your call via metal or optical wires. Alexander Graham Bell invented the first landline in 1876. As of 2013, 34 percent of Americans did not have a landline, and less than 8 percent of households use landlines as their sole source of telephone communication. Since 2004, landline usage has reduced from 92.7 percent to 58.1 percent, while the number of cellphone-only households has risen from 5 percent to 39.4 percent.
