Yes, almost all cordless phones use DC adapters. This applies to anything that has a DC adapter and a small thin cable that plugs into the device itself. Another way of checking is whether there is exposed metal that you can touch on the end that you're plugging into the device
You'll never see that if you're plugging AC power straight from the mains into a device:
Every adapter will show Input (AC volts, usually around 100-120 if it's US only, around 200-240V if it's rest-of-world only, around 100-240 if it's universal) and Output, in DC volts. The polarity is also normally shown, i.e. whether the positive or negative terminal is on the inside or outside of the connector.
