This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric diester bonds. The systematic name is glycoprotein-N-acetyl-D-glucosaminyl-phospho-D-mannose N-acetyl-D-glucosaminylphosphohydrolase. Other names in common use include α-N-acetylglucosaminyl phosphodiesterase, lysosomal α-N-acetylglucosaminidase, phosphodiester glycosidase, α-N-acetyl-D-glucosamine-1-phosphodiester, N-acetylglucosaminidase, 2-acetamido-2-deoxy-α-D-glucose 1-phosphodiester, and acetamidodeoxyglucohydrolase.
