Seven lines in the ground vibrational state and two lines in the lowest excited vibrational mode of urea were detected as unblended or marginally blended in the 3 mm wavelength region in the course of a new unbiased line survey toward the high-mass star-forming region Sagittarius (Sgr) B2(N) close to the Galactic center. The detections were made toward Sgr B2(N1S), a position about 1" south of the continuum peak of Sgr B2(N1). The molecule was not detected toward Sgr B2(N2).\\

The molecule was detected in the course of n unbiased molecular line survey of the quiescent giant molecular cloud G+0.693−0.027, about 1' north-east of Sagittarius B2(N), with the IRAM 30 m dish at 3 and 2 mm.
