 )\nThe extensions of the Standard Model based on the SU(3)C⊗SU(3)L⊗U(1
 )X gauge group are known as 331 models. Different properties such as the f
 ermion assignment and the electric charges of the exotic spectrum\, which 
 define a particular 331 model\, are fixed by a β parameter. In this work\
 , we study the electric charge quantization in two versions of the 331 mod
 els\, set by the conditions β=1/(33–√) and β=0. In these frameworks\
 , arise exotic particles\, for instance\, new leptons and gauge bosons wit
 h a fractional electric charge. Additionally\, depending on the version\, 
 quarks with non-standard fractional electric charges or even neutral appea
 r. Considering the definition of electric charge operator as a linear comb
 ination of the group generators that annihilates the vacuum\, classical co
 nstraints from the invariance of the Lagrangian\, and gauge and mixed gaug
 e-gravitational anomalies cancellation\, the quantization of the electric 
 charge can be verified in both versions.\n\nhttps://indico.uni.edu.pe/even
