Metal Service Centers and Offices
MCC 5051 is the four-digit Merchant Category Code (ISO 18245) for Metal Service Centers and Offices. Card networks and banks attach it to a merchant to describe what they sell, and it falls under the Retail outlet services group. The MCC can influence the cashback or rewards category a purchase earns, whether a surcharge is allowed, interchange pricing, and how the spend is reported — so two similar shops can differ if their acquirers categorised them differently.
