The SCU is made up of three distinct groupings or levels. Members can 'graduate' from one level to the next by going through riti battesimali (baptismal rites). The religious symbolism is probably left over from the SCU's association with the Camorra.

Società Minore – The lowest level. Is made up of lower-level criminals who do street-level activities. Members start out as picciotti and go through a 40-day trial to ensure they are suitable for criminal work and are not associated with the police. They are then inducted into the next phase of the level, the manovalanza, or worker. The candidate must also swear an oath of devotion to SCU.
Società Maggiore – The second level. Is made up of two positions.
Lo Sgarro – The position is given only to members who have killed at least three people for SCU, and from now on members cannot leave, on pain of death. Members can now form their own crew of picciotti, known as a filiale. Upon indoctrination into the La Santa position the member is given a firearm (to symbolically use on oneself upon failing SCU), a cyanide pill, cotton (representing Monte Bianco, which is considered sacred), a lemon (treating the wounds of one's comrades), a needle to puncture the index finger of the right hand, handkerchiefs (representing purity of spirit) and a spartenza (a gift of some sort, usually cigarettes).[5]
Società Segreta– The final level. Is the core of the organization where key decisions are made.
The Sacra Corona Unita consists of about 50 clans with approximately 2,000 members and specializes in smuggling cigarettes, drugs, arms, and people. The Sacra Corona Unita collects payoffs from other criminal groups for landing rights on the southeast coast of Italy.
