Each SIM card is internationally identified by a unique integrated circuit card identifier (ICCID). M2M One dispatch a packing slip with each order that lists each SIM with the ICCID(s).

Some of our SIM card sleeves and the SIM cards themselves have ICCID engraved on them. An ICCID example is 89610 00000 00000 12345.

M2M One use the ICCID as the primary identifier during SIM provisioning and inventory management.
