My name is ...
Our names are ...
Although it may seem easier for nonnative German speakers to say, "Mein Name ist. . ." ("My name is. . ."), native Germans rarely will communicate in that way. Instead, they will say or write, "Ich heiße.." ("I am called". . .).
"Ich heiße ...."
"I am called . . . "
"Wir heißen...."
"We are called . . . "
"Sie heißen ...."
"They are called . . . .
"Sie heißen ...."
"You (formal) are called . . . .
Note:
ß stands for sharp "ss" (also called eszett). Your keyboard probably doesn't include ß so you may want to substitute "ss" for it.
