In addition, the Blues were fined £460,000 along with the Football Association who were given a £390,000 penalty.
FIFA said in a statement: "The FIFA disciplinary committee has sanctioned the English club Chelsea FC and The Football Association for breaches relating to the international transfer and registration of players under the age of 18.
"Chelsea was found to have breached art. 19 of the Regulations in the case of twenty-nine (29) minor players and to have committed several other infringements relating to registration requirements for players.

"The club also breached art. 18bis of the Regulations in connection with two agreements it concluded concerning minors and which allowed it to influence other clubs in transfer-related matters.
"The disciplinary committee sanctioned Chelsea with a ban on registering new players at both national and international level for the next two (2) complete and consecutive registration periods.
"This ban applies to the club as a whole - with the exception of the women's and futsal teams - and does not prevent the release of players."
