Cross sections for e+p neutral current deep inelastic scattering have been measured at a center-of-mass energy of √(s)=318 GeV with the ZEUS detector at HERA using an integrated luminosity of 63.2 pb^\ensuremath-1. The double-differential cross section, d2\ensuremathσ/dxdQ2, is presented for 200 GeV2<Q2<30 000 GeV2 and for 0.005<x<0.65. The single-differential cross sections d\ensuremathσ/dQ2, d\ensuremathσ/dx and d\ensuremathσ/dy are presented for Q2>200 GeV2. The effect of Z-boson-exchange is seen in d\ensuremathσ/dx measured for Q2>10 000 GeV2. The data presented here were combined with ZEUS e+p neutral current data taken at √(s)=300 GeV and the structure function F2em was extracted. All results agree well with the predictions of the Standard Model.
