It is not toll-free. The toll-free codes in North America are 800, 888, 877, 866, 855, and 844, with 833 and 822 reserved for future toll-free use. Note that within Maryland, you can dial all local calls from a landline phone without using the '1' prefix. Thus, if you dial 443-xxx-xxxx from a landline phone and the call goes through, you can be assured that it is a local call. This technique works in Maryland and many other places, but not in all states.
